Open study recordThis research study evaluates the effects of an FDA-approved medication Gabapentin in individuals with Bipolar Disorder who smoke marijuana. Participants in the study will will be assigned to take either Gabapentin or a matched placebo. Study medication will be taken for 17 days. There will be 5 study visits, with 2 MRI brain imaging scans completed. Questionnaires and clinical interview measures will be completed at study visits along with consistent assessment of potential side effects from study medication.
This observational study will characterise the general psychiatric and general medical phenotypes of 100 adults, sequentially admitted to NHS General Adult Psychiatry (GAP) "mental health" inpatient wards, providing the first detailed information on morbidity in this patient population. It is often supposed that most patients who attend secondary care General Adult Psychiatry (GAP) services would be excluded from clinical trials because they have too many co-morbidities, they are 'treatment resistant' (have a condition that does not improve despite trying two or more standard treatments), and their conditions are too severe. Hence, it would be helpful to properly measure these variables in GAP patients using questionnaires and a review of the case notes to see how many GAP patients would indeed be excluded from clinical trials. It is anticipated that this will show that the participants in clinical trials are very different from 'real life' GAP patients, and that could explain why some promising results from clinical trials do not translate into useful new treatments. Also, this data could act as a benchmark or baseline against which to measure the efficacy of novel treatments and interventions. PRIMARY OBJECTIVE Using the most commonly employed diagnostic tools, severity rating scales, and a systematic review of the case notes, the typical characteristics of GAP patients will be described. SECONDARY OBJECTIVES The above data will be used to compared 'typical/real life' patients with the participants in impactful clinical trials. This is a cross sectional quantitative study. Participants will spend about an hour attending to the questionnaires and talking to their clinician. STUDY SETTING The study will take place in St John's Hospital, Livingston, West Lothian, on the acute psychiatric ward, and the outpatient department. STUDY POPULATION 100 patients who attend the West Lothian NHS GAP service will be consecutively recruited. These participants will be between 18 and 65 years old and suffering from mental disorders that their GP could not treat. IDENTIFYING PARTICIPANTS The usual clinical team will ask eligible patients if they would like to participate. CONSENTING PARTICIPANTS Consent will be thoroughly informed by an information leaflet and subsequent discussion with the involved clinician. Participants will take the information leaflet away with them and express their consent, or not, in their own time by using the contact details on the information leaflet, or when they next see their clinician. WITHDRAWAL OF STUDY PARTICIPANTS Participants will have the option of withdrawal from all aspects of the trial, but the data collected up to that point could be used. To safeguard rights, the minimum personally identifiable information possible will be collected. There are no stopping rules. Participants could withdraw at any time.
Open study recordPreliminary data have suggested that cannabidiol (CBD) may have a number of clinical benefits, including anti-anxiety and antidepressant properties. This study is a pilot open-label clinical trial assessing a custom-formulated high-CBD product over the course of 4 weeks in patients with bipolar disorder who experience anxiety. This investigation will be the first of its kind to conduct a clinical trial of an industrial hemp-derived high-CBD product in individuals with bipolar disorder who experience anxiety. Despite the recent interest in medical cannabis and cannabinoid-based products, the availability of hemp-derived products in all 50 states, and preliminary and anecdotal evidence suggesting that hemp-derived products may have a profound anxiolytic effect, along with potential antidepressant effects, no studies have conducted a clinical trial of a hemp-derived product in individuals with bipolar disorder who suffer from anxiety. This investigation consists of a four-week open-label clinical trial of the custom formulated hemp-derived high-CBD solution. Participants will be pre-screened by phone in order to evaluate their eligibility for the study. If approved, potentially eligible participants will come to the hospital for a screening visit, and will complete a structured clinical interview, clinical and quality of life questionnaires, a urine screen, and a blood draw. Eligible participants will return for a baseline visit consisting of additional clinical and quality of life questionnaires, a brief cognitive assessment, and a buccal swab for genetic analysis. Participants will be given study product to use for the duration of the study, and will be instructed to self-administer the solution under the tongue twice daily for four weeks. Throughout the treatment period, participants will complete short in-person or remote visits on a weekly basis, where they will complete questionnaires about their mood and quality of life. Participants will also return to the hospital for a final visit after four weeks of treatment to complete additional questionnaires and cognitive assessments.
Open study recordThe purpose of this study is to evaluate Community Reinforcement and Family Training for Early Psychosis (CRAFT-EP) for families experiencing early psychosis and substance use delivered exclusively or primarily via telehealth (video conferencing). The intervention aims to improve treatment engagement, substance use patterns, and family wellbeing. To assess preliminary outcomes of the intervention, this study compares CRAFT-EP plus treatment as usual (TAU) compared to TAU alone. Family members will be randomized to CRAFT-EP + TAU or TAU alone. Data on family members and clients with psychosis will be collected for assessment purposes; if a client with psychosis does not have a family member participating in the study, the client with psychosis will be automatically be assigned to the TAU alone group. Total target enrollment is 40 family members and 40 clients with psychosis. Given that family members may participate without a corresponding client with psychosis due to fear of disclosing their participation in the study to the client or client lack of interest, and because the intervention works directly with family members and indirectly with clients, data collected from clients with or without a corresponding family member participating in the study will be hypothesis generating.
Open study recordHypothesis: the hypothesis of the study is that aerobic physical exercise (PE) performed with the method Braining accelerates recovery from bipolar depression as well as improves psychiatric and somatic health in individuals with bipolar depression Method: a randomized controlled trial with 54 patients with bipolar depression are randomized to 6 weeks of either 1) supervised aerobic PE 3 times/week, 2) supervised relaxation/stretching 3 times/week or 3) information about PE but no supervised activity. The hypothesis of this study is that adding aerobic PE might accelerate recovery, reduce negative side effects, improve mental wellbeing and function, increase long term prevention against relapsing bipolar episodes and reduce risk for complications such as cardiovascular disease in patients with bipolar disorder. Furthermore the study aims to evaluate if the effect of PE is linked to biological factors such as genetical factors, stress hormone levels, level of inflammation and other biological markers for health and disease that can be measured in standard blood samples. Patients diagnosed with bipolar disorder with ongoing depression are invited to participate in the study at regular visits in the psychiatric clinic. All study participants are medicated with mood stabilizers according to routine treatment and receive regular treatment for bipolar depression. After informed consent the study participants will be randomized to one of three groups 1) moderate to vigorous PE group training together with psychiatric staff three times per week 2) relaxing and stretching exercises group training together with psychiatric staff three times per week 3) information about PE and relaxation but no supervised PE or relaxation/stretching, for the 6 weeks of the study period. BEFORE: The first week consists of pre-test including interview regarding medical history and physical and psychiatric examination, ECG and blood samples. To measure level of physical activity the participants wear an activity monitor, Actiheart, that continuously registers physical activity for 7 days. The study participants will also fill out different questionnaires regarding general health and psychiatric symptoms. STUDY PERIOD: During the 6 weeks long study period the participants fill out an activity questionnaire and health questionnaires once a week. AFTER: during the sixth week of the study period evaluation is being performed with repetition of the physical and psychiatric examination, blood samples and questionnaires. After 1, 2 and 3 years after the exercise period the questionnaires are repeated. Blood samples are repeated one year after the study period.
Open study recordThis study will evaluate the effectiveness of valbenazine on patient- and clinician-reported outcomes assessing health-related quality of life, functioning, and treatment effect in participants with tardive dyskinesia (TD) who are receiving valbenazine for up to 24 weeks.
Open study record"Braining" is a clinical method for physical exercise as adjunctive therapy in psychiatric care. The core components are personnel-led group training sessions and motivating contact with psychiatric staff, as well as measurement and evaluation before and after the training period of 12 weeks. Objective. This study aims to describe the clinical and demographic variables in the population of patients who participated in Braining 2017-2020, investigate the feasibility of Braining, and analyse perceived short-term effects and side effects of Braining regarding psychiatric and somatic symptoms. Method. The project is a retrospective, descriptive study. Patients at Psykiatri Sydväst (PSV, Psychiatric Clinic Psychiatry Southwest, Stockholm) who participated in Braining 2017-2020 during at least 3 training sessions, will be asked for inclusion. Medical and demographic data, as well as patient treatment evaluations, are already available in medical records. Additionally, an extended 2-year long-term follow-up will be carried out. This includes blood and hair sample, physical examination as well as qualitative interviews with a representative subgroup. The method "Braining" is a clinical invention that helps patients to initiate and execute physical exercise (PE) regularly in psychiatric care. The core components are basic high performance group training sessions and motivational work led by the psychiatric staff. Braining is used as add-on treatment to regular psychiatric care (treatment as usual; TAU) and is included in the patient care plan. Braining is unique in that it: 1. Includes trained psychiatric clinical staff leading group exercise sessions together with patients from both out- and inpatient ward units in daily, high endurance group training sessions. 2. Is included in regular healthcare fee (free of charge). 3. Includes a motivational and educational visit (as either a group seminar or as an individual visit) at the start and end of a training period; usually 12 weeks. 4. Includes regular measurements (self-assessment questionnaires, blood samples, physical and mental health examination and education before and after the twelve week training period). 5. Includes short individual motivating visits before every training session, including assessment of day shape and fitness to participate. The scientific purpose of the project is to: * Describe clinical and demographic variables in patients participating in Braining 2017-2020. * Investigate the feasibility of the Braining method (PE together with staff as adjunctive therapy in Psychiatric care). * Analyse perceived short-term effects and side effects of Braining regarding psychiatric and somatic symptoms (degree of psychiatric symptoms, changes in molecular and cardiovascular parameters, lifestyle patterns, level of functioning and perceived quality of life). Also, if possible, provide an estimate of what long-term effects that might be expected in coming long-term clinical follow-ups. * Investigate patients' long term experience of Braining participation through qualitative interviews as well as analyse status and change of biomolecular markers two years after inclusion. Specific goals: All patients at PSV who participated in Braining 2017-2020 during at least 3 training sessions and do not meet the exclusion criteria will be asked for inclusion. For this population the investigators plan to describe: * Demographic and medical variables (such as diagnosis, age, gender, functional level, staff-assessed severity of psychiatric disease, self-assessment scales for symptoms of depression, mania / hypomania, and anxiety, self-assessed health-related quality of life, degree of sick leave, ongoing pharmacological treatment, ongoing CBT (cognitive behavioral therapy), need for emergency visits, inpatient care, suicidal attempts). * Feasibility of the Braining method. Evaluation of the degree of participation in Braining (such as number of training sessions performed, participation over time, differences between subgroups, possible incidents) as well as the participants' experience of Braining (based on surveys and follow-up interviews: positive or negative subjective assessments of the method, to what extent is the method recommended to other patients). Adverse events. * Differences before and after Braining in terms of statistically significant change in \[I\] degree of psychiatric symptoms and function, \[II\] cardio metabolic factors such as blood pressure, BMI, waist measurement, weight, \[III\] molecular parameters such as serum concentration of blood lipids, fasting blood sugar, HbA1c, CRP, \[IV\] health-related quality of life, \[V\] level of social function (such as work/study/sick leave) and care needs (such as need of inpatient care, medicine, emergency visits), \[VI\] assessed severity of psychiatric disorder, \[VII\] lifestyle patterns such as exercise, sleep, diet, substance use.
Open study recordSevere mental illness (SMI) refers to the most burdensome psychiatric conditions. The need to pre-empt the onset of SMI is pressing because once SMI develops, quality of life is poor and available treatments have limited efficacy. Most risk factors for SMI are either unchangeable (e.g., genetics) or difficult to alter (e.g., low socio-economic status). In contrast, cannabis use is one specific risk factor that could be avoided. Certain individuals are more vulnerable to the harmful effects of cannabis. Genetic factors can help us identify these high-risk individuals. One in three individuals are carriers of a higher-risk genetic variant, and cannabis users with this genotype are at up to 7-fold increased risk of developing schizophrenia. In our study, genetic counselling will be provided to participants by a board-certified genetic counsellor. During the genetic counselling session, participants will have the option to receive their genotype. Participants will be counselled regarding their individualized risk of developing and of not developing SMI based on family history, whether or not they choose to use cannabis, and genotype (if the participants accept the genetic test results). The investigators hypothesize that this intervention will reduce exposure to cannabis compared to the youth who are not offered the intervention. Severe mental illness (SMI) refers to the most burdensome forms of psychiatric disorder, including schizophrenia, bipolar disorder, and severe depression. These illnesses typically emerge in adolescence or young adulthood and are associated with substantial impairment in functioning. A significant proportion (\~30%) of individuals with SMI remain resistant to any form of available pharmacotherapy. The combination of early onset, poor response to treatment and persistent disability makes SMI the most problematic group of illnesses to individuals and society. The need for early interventions to pre-empt the onset of SMI is pressing because once SMI develops, quality of life is poor for patients and their families. There is substantial overlap in the genetic and environmental risk factors for individual forms of SMI, and predictors of SMI are not specific to any one disorder. It is therefore necessary to conceptualize SMI as transdiagnostic and include diagnoses of schizophrenia, bipolar disorder, and depression, rather than focusing on single illnesses when developing preventative interventions. Prevention of SMI is currently hindered by the inability to identify those at risk early enough to normalize their developmental trajectory. Recent advances in genomics and the understanding of important gene-environment interactions may help overcome this challenge and enable effective and targeted prevention of SMI. Cannabis exposure during critical periods of brain maturation is an avoidable environmental risk factor for SMI. A replicated gene-cannabis interaction shows that carriers of a common genetic variant (C alleles at rs2494732 in the AKT1 gene) are at up to 7-fold increased risk of developing psychosis if they use cannabis. Genetic counselling provides a powerful tool to communicate genetic information to youth in a way that empowers and enhances health. The present project involves the delivery of a genetic counselling intervention to inform youth of their personalized risk of developing SMI based on genotype, family history, and whether or not they choose to use cannabis. This project will be the first application of molecular genetic information and genetic counselling to prevent SMI. Aim: To test if genetic counselling regarding personalized risk information based on a replicated gene-cannabis interaction reduces cannabis use in youth at high risk of developing severe mental illness. Hypotheses: 1. A genetic counselling intervention will be acceptable to youth at high familial risk of SMI. 2. A genetic counselling intervention with personalized feedback of AKT1 genotype will reduce cannabis use among vulnerable youth. 3. The effect of the intervention will be moderated by AKT1 genotype, with greater reduction of cannabis use among carriers of the sensitive C alleles. Method: A cohort of over 450 youth (aged 3-29) has been enrolled as part of the Families Overcoming Risks and Building Opportunities for Well-being (FORBOW) study. The investigators have obtained biological samples for measurement of genetic variation and the investigators will obtain biological samples to measure cannabis exposure. The investigators will randomly select one in every two eligible youth (aged 12-21) to be offered genetic counselling during which the participants will be provided with personalized genetic information and they will be counselled regarding risk of developing SMI based on genotype, family history, and whether or not they choose to use cannabis. The investigators will follow the participants through the developmental period with the highest risk of cannabis use initiation and the investigators will assess cannabis use and psychopathology annually. The primary outcome will be abstinence from cannabis reported by participants in confidential interviews and confirmed by measurement of the primary metabolites of psychoactive Δ9-tetrahydrocannabinol in blood and urine samples. Significance: This project will realize the first translational application of a gene-environment interaction to improve mental health and test an intervention with potential public health benefits.
Open study recordBipolar disorder (BD) is a lifelong condition characterized by recurrent episodes of depression and (hypo)mania. Periods of chronic and recurring depressive episodes are more common and can be severely disabling. Effective treatments exist; however, a significant portion of bipolar depressed patients do not respond to or have difficulty tolerating many of these interventions and thus look beyond established treatments to achieve symptom relief. Cannabidiol (CBD), a chemical from the Cannabis sativa plant, has shown to have some beneficial effects on mood symptoms in a few small studies which assessed its effects in other mental and physical health conditions, but no large studies have been conducted to assess its safety and efficacy in bipolar depression. Additionally, several clinical studies have shown CBD to be safe and tolerable. The primary objective of this study is to assess the effectiveness, safety and tolerability of cannabidiol in patients with bipolar depression (BD I or BD II) who have not responded to adequate trials with at least one first-line treatment for bipolar depression in comparison to those who will be treated with placebo. Placebo is an inactive substance that looks identical to the study medication but contains no therapeutic ingredient. This study is a randomized (like the flip of a coin), double-blind (you and the study team will not know which treatment arm you receive) study in which participants will receive either CBD or placebo added to their current treatment. Participants will have 5 clinical appointments and a phone appointment over a period of 10 weeks. This is a Phase 3, 6-week, double-blind, parallel group randomized controlled trial to assess the efficacy, safety and tolerability of adjunctive CBD vs placebo in patients with acute bipolar depression (BD I or BD II) who have not responded to adequate trials with at least one first-line treatment for bipolar I disorder (i.e. lithium, lamotrigine, lurasidone, or quetiapine either as monotherapy or adjunctive therapy), or at least one first or second-line treatment for bipolar II depression (i.e. quetiapine, lithium, lamotrigine, sertraline, or venlafaxine as monotherapy or adjunctive therapy, or bupropion adjunctive therapy). After the baseline visit, patients who meet the eligibility criteria will enter a 6-week double-blind treatment phase during which participants will be randomized to adjunctive CBD or identical placebo. Participants will be assessed at the screening visit, baseline visit, weeks 2, 4, and 6, or endpoint visit. All participants will receive a follow-up telephone call 2 weeks after the 6-week study endpoint or early termination visit to assess well-being. All participants will continue treatment with their mood stabilizer and/or atypical antipsychotic as prescribed by their treating physicians.
Open study recordCannabis use is associated with younger age at onset of bipolar disorder, poor outcome, and more frequent manic episodes, but the effects of cannabis on cognition are less clear. Contrary to reports among non-psychiatric patients, cannabis may improve cognition among people with bipolar disorder. Nevertheless, no study to date has systematically tested the acute effects of cannabis on cognition in bipolar disorder. Therefore, the investigators propose to determine the effects of oral cannabinoid administration on cognitive domains relevant to bipolar disorder, e.g., arousal, decision making, cognitive control, inhibition, and temporal perception (sense of timing). In addition, the investigators will evaluate different doses of the two major components of cannabis, cannabidiol and ∆9-tetrahydrocannabinol, and compare them to placebo on these neurocognitive measures. The investigators will also test the effects of acute exposure to cannabinoids on cerebrospinal levels of anandamide and homovanillic acid - markers of endocannabinoid and dopamine activity in the brain, respectively. These studies will provide information that effectively bridges the fields of addiction and general psychiatry, informing treatment development for co-morbid substance abuse and psychiatric disorders.
Open study recordThe objective of this study is to assess the changes in symptoms and cognition that occur after a 28-day abstinence period in patients with comorbid Cannabis Use Disorder (CUD) and Bipolar (Type I or II) disorder. Stabilized bipolar patients (N=52) with CUD will be randomly assigned to one of two groups: 1) A contingent reinforcement (CR) group (n=26); 2) a non-contingent reinforcement (NCR) group (n=26). The study will include a total of 8 visits to the CAMH Russell site (screening, training, baselines, week 1-4, follow-up). Participants should be between the ages of 18-60, meet criteria for CUD (moderate to severe), meet criteria for Bipolar Disorder, be on a stable dose of mood stabilizing medication(s), and be non-treatment seeking cannabis user. The visits will take up a total of approximately 22.5 hours with compensation for time provided for both groups. These visits will involve multiple clinical, substance use, and cognitive assessments. Abstinence will be maintained by weekly behavioural coaching sessions and contingency reinforcement for the CR group.
Open study recordThe purpose of this study is to develop and evaluate an intervention that adapts Community Reinforcement and Family Training (CRAFT) for families experiencing first episode psychosis and substance use delivered via telemedicine (video conferencing). The intervention aims to improve treatment engagement and reduce distress, and it will be delivered via telemedicine (CRAFT-FT). To assess feasibility of the intervention, family members will complete the sessions and provide feedback to refine the treatment manual. Data on client relatives with psychosis will be collected for preliminary assessment purposes. Client relatives will not complete the research study intervention.
Open study recordThis will be a multistate, multicenter clinical study to determine the efficacy and safety of medical cannabis for a wide variety of chronic medical conditions. Medical cannabis has been legal in parts of the USA since 1996, with the stated intention of reducing pain (both acute and chronic) as well as for treatment of multiple other conditions. The original implementation of medical cannabis in the USA was implemented in California as a compassionate measure to treat the HIV/AIDS epidemic. Additional studies have shown promising outcome for patients with multiple sclerosis, seizures, cancer, and other chronic conditions. However, there have been few comprehensive studies that have actually measured whether cannabis is an effective treatment for pain reduction. There is an absence of multistate, multicenter clinical studies with cannabis as medicine, not only in the USA but globally. With the expansion of medical cannabis into more than 38 states in the US, this type of clinical study is now feasible. On March 11, 2020, the World Health Organization formally characterized coronavirus, COVID-19, as a global pandemic and health systems globally are continuing their efforts to manage the outbreak. Coronavirus disease COVID-19 is an infectious disease caused by a newly discovered coronavirus. With the rapidly growing pandemic of COVID-19 caused by the new and challenging to treat zoonotic SARS-CoV2 coronavirus, there is an urgent need for new therapies and prevention strategies that can help curtail disease spread and reduce mortality. Inhibition of viral entry and thereby spread constitute plausible therapeutic avenues. This study will utilize an anonymous novel online questionnaire to determine study participants' qualifying condition(s) for medical cannabis use, cannabis ingestion method, frequency of use, prescription drug use, and demographic information. Secondary factors will include evaluation of pain control, quality of life metrics, any adverse side effects from cannabis use, as well as changes in adjunctive treatments. Patients will be given medical cannabis recommendations and certifications commensurate with the state law in which the encounter occurs. The variations in mechanisms between the states for recommending, registering, certifying, and developing mandated treatment plans or doses will be adhered to; however, variations in state law and cannabis programs should not cause variation in the study design because the end-result is still the same with patients being treated with medical cannabis.
Open study recordThe overarching goal of this study is to characterize the acute cognitive and psychophysiological effects of the main psychoactive constituent of cannabis, 9-delta-tetrahydrocannabinol (THC) in individuals with euthymic bipolar disorder (BD), and to begin probing the mechanisms that may underlie its effects in this illness. This study is expected to contribute to a better characterization of specific effects of THC in individuals with BD compared to healthy controls (HC). To compare the dose related acute effects of inhaled THC, administered through a vaporizer over approximately 20 minutes, between HC and euthymic BD individuals (referred to as eBD) on a range of subjective and objective parameters as described below: Primary Aims: * Verbal memory, measured by a modified computer version of the Rey Auditory Verbal Learning Test (RAVLT) and/or the CogState battery, administered while EEG data is collected. * Executive functioning measured by the CogState battery and/or Trails Making Test-Part B. Secondary Aims: * Attention, measured by the Continuous Performance Test-Identical Pairs (CPT-IP). * Working memory, measured by the Wechsler Memory Scale-3 Letter-Number Sequencing. * Mood, measured by the Profile of Mood States (POMS). * Psychotic-type experiences, measured by the Psychotomimetic States Inventory (PSI) and/or the Clinician Administered Dissociative Symptoms Scale (CADSS). * Anxiety symptoms, measured by the Visual Analog Scale for Anxiety (VAS-A). * Impulsivity, measured by the Balloon Analogue Risk Task (BART). Exploratory aims: •Serum prolactin, serum ACTH, serum cortisol and serum endocannabinoid levels.
Open study recordDepressive symptoms are associated with significant psychosocial impairment. However, current treatments of bipolar depression are only partially effective. Cannabidiol is a natural component of cannabis without psychotomimetic or addictive properties. Cannabidiol has been shown to produce therapeutic effects including anticonvulsive, anxiolytic, antipsychotic and neuroprotective effects. The investigators hypothesize that treatment with cannabidiol will result in improvement of depressive and anxiety symptoms, as well as, improvement in functioning and inflammatory biomarkers. During the clinical trial, subjects will receive study medication (cannabidiol 150-300mg/day) or placebo for a period of 12 weeks.
Open study recordThe objective of this study is to determine whether the practice of a non-drug related intervention technique (behavioral modification technique consisting of a combination of breathing exercises, cold exposure and meditation) has an effect on long-term cannabinoid receptor function in a control group as well as in a group of patients suffering from bipolar affective disorder (BAD). Specifically, the objective of this study is to test whether the applied behavioral modification technique is able to alter cannabinoid receptor density in brain areas that modulate mood and motivational drive (such as vmPFC, PAG, VTA, amygdala and OFC). The investigators believe that these studies will form the impetus for a better understanding and deployment of non-drug related treatment methods in patients with various depressive symptoms. In particular, it appears that the proposed behavioral modification technique might be a powerful, currently under-appreciated, method to positively modulate the brain's own cannabinoid system. Bipolar affective disorder (BAD) is often poorly controlled by prescribed drugs. Clinical observations suggest that the endocannabinoid system is dysfunctional in BAD and fails to control the level of cortical excitation and inhibition in the brain. Thus, excessively high endocannabinoid tone (mania) or excessively low endocannabinoid tone (depression) may manifest itself in BAD patients. Interestingly, cannabis use is common in patients with this disorder and anecdotal reports suggest that some patients take it to alleviate symptoms of both mania and depression. The investigators have recently studied brain activations during a cold stress paradigm in a 57 year old Dutch national (Wim Hof), the so-called "Iceman", who has the ability to withstand frequent prolonged periods of extreme cold exposure using a self-developed technique that includes a combination of breathing exercises, cold exposure and meditation (referred to as the WH technique). The WH technique allows the "Iceman" to regulate his own autonomic nervous system in the presence of severe cold and to perform remarkable acts of survival under extreme thermal conditions. Moreover, it has been shown that the WH technique can be successfully taught to novice users. Preliminary studies performed by the investigators have examined CNS mechanisms associated with the practice of the WH technique and the obtained findings unequivocally demonstrated activation of autonomic brainstem areas that are implicated in stress-induced analgesia as well as cognitive cortical areas that are associated with self-reflection (such as the anterior insula). In particular, a strong activation of the periaqueductal gray (PAG) was determined, which is implicated in the release of endogenous opiates/cannabinoids that mediate decreased sensitivity to cold exposure and (via connections to higher-order cortical areas) promote a feeling of euphoria and well-being. This finding suggests that the WH technique might allow practitioners to assert increased level of control over key components of the affective system and as a result might be a viable, non-drug related approach for patients with pathological mood swings. The investigators believe that this method might be particularly effective in patients suffering from BAD, as the practice of the WH technique can be implemented during both remission and at the onset of highly motivational manic episodes, which will then help to limit the effects of negative mood swings during depressive (and manic) episodes. The investigators will study the effects of the WH technique on cannabinoid receptor density using the cannabinoid PET tracer (F18-FMPEP-d2) by determining regional changes in cannabinoid receptor density in various brain regions prior and post behavioral intervention.
Open study recordThis study will determine the efficacy and safety of combination therapy with divalproex and lithium for treating mania in people with rapid cycling bipolar disorder and a substance abuse disorder. Longitudinal Evaluation of the Efficacy and Safety of Divalproex and Lithium in Dual Diagnosis Bipolar Rapid Cycling: This study recruits males and females age 18 and older who currently meet diagnostic criteria for rapid cycling bipolar disorder (type I or II) and who have met the criteria for substance abuse or dependence of cocaine, marijuana and/or alcohol within the past six months. Patients are initially stabilized on dual therapy of lithium and depakote and then randomly assigned to double-blind treatment with either lithium monotherapy or continued dual therapy. Patients remain in the study for six months or until they experience a relapse. Patients in this study are required to bring a friend or family member to all study visits as well as attend chemical dependency services. This study is sponsored by the NIMH. Subjects receive study-related care at no cost.
Open study recordThe objectives of this study are to determine whether this treatment may be useful for reducing cannabis consumption; reducing symptoms of bipolar mania; and weight mitigation therapy for individuals on psychopharmacotherapy. The purpose of this research study is to study the effects (both good and bad) of combining medicines, called quetiapine and topiramate, for treating your symptoms, and other children and adolescents' symptoms, of bipolar mania (an illness with periods of elation, excessive excitement, irritability, high energy, racing thoughts, poor sleep, poor judgment, reckless behavior). It is estimated that 1% of the population of adolescents in the United States has bipolar disorder. The purpose of this research study is also to study the effects (both good and bad) of combining the same two medicines, quetiapine and topiramate, for reducing your use, and other children and adolescents' use, of cannabis (commonly referred to as "pot"). It is estimated that 30.5% of adolescents in the United States have used cannabis at least once in their lifetime. Additionally, the purpose of this research is to look at how bipolar disorder and cannabis use effects brain chemicals and function. Quetiapine (marketed under the brand name Seroquel) has been approved by the FDA since 1997 to help adults who suffer from schizophrenia (an illness of feeling, thought, perception and behavior). On January 12, 2004, the FDA approved quetiapine for the treatment of bipolar symptoms in adults. As of December 2009, Quetiapine has now been approved by the FDA for use in adolescents (13-17 years of age) for the treatment of schizophrenia and for the treatment of manic episodes associated with bipolar I disorder in children and adolescents (10-17 years of age). Bipolar disorder is an illness characterized by recurrent mood swings including mania (i.e., periods of elation, excessive excitement, irritability, high energy, racing thoughts, poor sleep, poor judgment, reckless behavior) and clinical depression (i.e., a depressed mood, loss of interest in activities and disruption of sleep, appetite and energy). This study is being carried out to see if quetiapine is effective and safe for treatment of children and adolescents who have the symptoms of bipolar mania. This study is also being carried out to see if quetiapine, in combination with topiramate, will further reduce bipolar mania and reduce cannabis use. As of December 2, 2009, the US Food and Drug Administration (FDA) approved SEROQUEL (quetiapine fumarate) tablets for the treatment of schizophrenia in adolescents (13-17 years of age) as monotherapy, and for the acute treatment of manic episodes associated with bipolar I disorder in children and adolescents (10-17 years of age), both as monotherapy and as an adjunct to lithium or divalproex. Topiramate (marketed under the brand name Topamax) is approved by the U.S. FDA for the prevention of migraine headaches in adults. The FDA has also approved topiramate for epilepsy (a seizure disorder) and for use as adjunctive therapy (meaning in combination with other medicines) for partial onset seizures in adults. Topiramate is not approved by the FDA for use in adults or for use in children and adolescents who have bipolar disorder. This study is being done to see if topiramate, in combination with quetiapine, will reduce bipolar mania and reduce cannabis use. The FDA has declared research studies with MRI field strengths up to and including 8 Tesla (a measure of field strength) as non-significant risk. This research study uses an MRI with a field strength of 4 Tesla.
