Newest firstIntroduction Regular cannabis use is associated with attenuated neural reward signaling, primarily measured through monetary or drug-cue tasks. Yet, minimal research has studied functional positive face processing in inhibitory control contexts, particularly amongst cannabis-using adolescent and young adults. The present study seeks to investigate functional response differences in whole-brain and ventral striatal…
Open article record in new tab ↗Background A common feature of cannabis use disorder (CUD) is an intense reactivity to cannabis cues, which are becoming increasingly visible due to the growth in its decriminalization, accessibility, and marketing of cannabis products. The brain's automatic reactivity to cannabis cues can trigger craving and subsequent use. In this study, we aimed to test neural activity during cannabis cue reactivity in non-trea…
Open article record in new tab ↗PURPOSE OF REVIEW: This review evaluates structural neuroimaging research on substance-related psychosis to determine if these conditions share common neurobiological pathways with primary psychotic disorders, such as schizophrenia, or exhibit unique signatures. RECENT FINDINGS: Research indicates that methamphetamine, cannabis, and cocaine induce significant structural changes, including cortical thinning and gre…
Open article record in new tab ↗Background Progressive supranuclear palsy (PSP) and corticobasal degeneration (CBD) are 4-repeat tauopathies (4RT) presenting with overlapping syndromes. Imperfect clinicopathological associations increase sample-size demands in clinical trials. We test whether MRI can enrich trials for PSP/CBD and provide sensitive MRI-based outcome measures. Methods Longitudinal cohort analysis including participants from the 4…
Background Cannabis constituents, including Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD), show distinct pharmacological profiles with therapeutic relevance for neurological and psychiatric conditions. THC exerts euphoric effects primarily via CB1 receptor activation, while CBD displays non-euphoric properties affecting various pathways. Aims This study evaluated the effects of THC, CBD, and their combinatio…
Mounting evidence implicates inflammation as a key factor in Alzheimer’s disease (AD) development. We previously identified pro-inflammatory soluble epoxide hydrolase (sEH) metabolites to be elevated in plasma and CSF of AD participants and to be associated with lower cognition in non-AD subjects. Soluble epoxide hydrolase is a key enzyme converting anti-inflammatory epoxy fatty acids to pro-inflammatory diols, re…
Background Impaired inhibitory control has been observed in regular cannabis users. Theories suggest that regular cannabis use is maintained by reward-driven behaviour, which may be underpinned by adaptations in neural reward and inhibitory control systems, thus increasing vulnerability to dependency. Aims This study investigated neural correlates of cannabis cue-specific inhibitory control in regular cannabis use…
BackgroundDizziness is a frequent presenting complaint in the emergency department (ED), prompting extensive diagnostic evaluation. Non-contrast brain computed tomography (CT) is often utilized to rule out serious central pathologies, but its diagnostic yield is debated, leading to concerns about overuse. This study aimed to identify clinical predictors associated with abnormal brain CT findings in patients with a…
Background Adolescent substance use initiation is shaped by multiple genetic and neurobiological factors. Externalizing liability, a transdiagnostic genetic dimension capturing shared predisposition to impulsivity, disinhibition, and related traits, is among the strongest polygenic predictors of early substance initiation. Yet how this genetic risk relates to brain structure and function, and whether baseline brai…
Open article record in new tab ↗Increased extracellular glutamate concentrations in the brain can cause neuronal injury. Cannabinoid use has been demonstrated to reduce extracellular glutamate levels in the brain in many animal models. However, there are no systematic reviews published evaluating the effect of cannabis on glutamate levels in the human brain. This review aimed to review studies that investigated the effect of cannabinoids on glut…
Open article record in new tab ↗Purpose The monoacylglycerol lipase (MAGL) plays a pivotal role in modulating the endocannabinoid system and is considered an attractive therapeutic target for diseases in both the central nervous system and periphery. The current study aimed to develop and evaluate a suitable carbon-11 labeled tracer for imaging MAGL in preclinical studies. Methods (R)-YH168 was synthesized via a multi-step pathway and its half-m…
Alcohol use disorder (AUD) is a prevalent psychiatric condition characterised by problematic alcohol consumption and craving, necessitating the exploration of novel therapeutic interventions. Cannabidiol (CBD), a non-psychoactive component of cannabis, has shown potential in modulating neural processes associated with substance use disorders including AUD. This study aimed to investigate the effect of CBD on alcoh…
Though usually described as isolated models, neurodegenerative diseases exist in a significant proportion of cases as mixed pathologies, particularly in older adults. The presence of co-pathologies may influence phenotypes and progression, and the correct classification in vivo has proven to be challenging, particularly without proper biomarker panels. Recent breakthroughs in biomarkers, enabling earlier detection…
Open article record in new tab ↗Introduction Adolescence and young adulthood are simultaneously periods of significant brain development and the ages in which people often initiate cannabis use. This has led to significant interest in researching the effects that cannabis use in this period might have on the brains of users. This scoping review aims to summarize existing neuroimaging research on the effect of cannabis use in adolescence and/or y…
Open article record in new tab ↗The underlying neurobiological mechanisms of cannabidiol's (CBD) management of alcohol use disorder (AUD) remains elusive.Aim We conducted a systematic review of neuroimaging literature investigating the effects of CBD on the brain in healthy participants. We then theorise the potential neurobiological mechanisms by which CBD may ameliorate various symptoms of AUD.Methods This review was conducted according to the…
Open article record in new tab ↗Background Cannabidiol (CBD) impacts brain regions implicated in anxiety reactivity and stress reactivity (e.g., amygdala, anterior cingulate cortex (ACC), anterior insula (AI)); however, placebo-controlled studies are mixed regarding CBD's anxiolytic effects. We previously reported that CBD expectancy alone can alter subjective, physiological, and endocrine markers of stress/anxiety; however, it is unclear whethe…
Background This case report presents a patient with progressive memory loss and choreiform movements. Case presentation Neuropsychological tests indicated multi-domain amnestic mild cognitive impairment (aMCI), and neurological examination revealed asymmetrical involuntary hyperkinetic movements. Imaging studies showed severe left-sided atrophy and hypometabolism in the left frontal and temporoparietal cortex. [18…
Open article record in new tab ↗While continued cannabis use and misuse in individuals with schizophrenia is associated with a variety of negative outcomes, individuals with a history of use tend to show higher cognitive performance compared to non-users. While this is replicated in the literature, few studies have used task-based functional magnetic resonance imaging (fMRI) to evaluate whether the brain networks underpinning these cognitive fea…
Open article record in new tab ↗Current treatments for alcohol use disorders (AUD) have limited efficacy. Recently, Cannabidiol (CBD) has been examined in a multitude of clinical settings. Preclinical and clinical results suggest that CBD might be particularly well suited for the treatment of AUD and may reduce alcohol cue and stress-induced craving and alcohol seeking. This study aims to investigate this new pharmacotherapy with a particular fo…
Background Interactions between the endocannabinoid system (ECS) and neurotransmitter systems might mediate the risk of developing a schizophrenia spectrum disorder (SSD). Consequently, we investigated in patients with SSD and healthy controls (HC) the relations between (1) plasma concentrations of two prototypical endocannabinoids (N-arachidonoylethanolamine [anandamide] and 2-arachidonoylglycerol [2-AG]) and (2)…
