Newest firstBackground Several studies have reported associations between attention-deficit/hyperactivity disorder (ADHD) and substance use disorders (SUD). However, sex-differences in ADHD and SUD, especially when associated with other psychiatric comorbidities, are less studied. Objective To compare the prevalence of SUD among individuals with and without ADHD to describe groups, defined by sex and psychiatric comorbidity,…
Open article record in new tab ↗Background Cannabis use is elevated in youth with depression and attention-deficit/hyperactivity disorder (ADHD), but drivers of this increase remain underexplored. The self-medication hypothesis suggests cannabis is used by patients for mood regulation, a common difficulty in ADHD and depression. This study aimed to examine associations between mood instability and cannabis use in a large, representative clinical…
Background Risky sexual behaviours (RSB) and attention deficit hyperactivity disorder (ADHD) are both major concerns among university students. However, their association remains insufficiently understood. This study aimed to evaluate the relationship between ADHD symptoms and a broad range of RSB in university students. Methods A total of 13 085 French students enrolled in the i-Share (Internet-based Students' He…
Observational studies suggest that child maltreatment increases the risk of externalizing spectrum disorders such as attention deficit hyperactivity disorder (ADHD), conduct disorder (CD), antisocial personality disorder (ASPD), and substance use disorder (SUD). Yet, only few of such associations have been investigated by approaches that provide strong evidence for causation, such as Mendelian Randomization (MR).…
IntroductionAttention-deficit/hyperactivity disorder (ADHD) treatment and diagnoses show marked international and regional variation, not fully explained by underlying morbidity. In Denmark, earlier studies reported substantial regional differences, raising concerns about inequities in access to care. We examined nationwide patterns of ADHD medication use and diagnosis in 2024 and assessed system-level factors pot…
Open article record in new tab ↗Objective To evaluate the prevalence of attention-deficit/hyperactivity disorder (ADHD), comorbidity rates with disruptive behavior disorders and main negative outcomes in primary school students in Nampula, Mozambique. Methods We selected a random sample of 748 students for ADHD screening from a population of around 43,000 primary school students. The Swanson, Nolan, and Pelham Rating Scale version IV was applied…
Paracetamol is commonly used to treat fever and pain in pregnant women, but there are growing concerns that this may cause attention deficit hyperactivity disorder and autism spectrum disorder in the offspring. A growing number of epidemiological studies suggests that relative risks for these disorders increase by an average of about 25% following intrauterine paracetamol exposure. The data analyzed point to a dos…
Gilles de la Tourette syndrome (TS) is a complex neurodevelopmental disorder characterized by the presence of motor and vocal tics as well as psychiatric comorbidities such as attention-deficit/hyperactivity disorder (ADHD), obsessive-compulsive disorder (OCD), depression, and anxiety. The underlying cause of the disease is still unknown, but several lines of evidence suggest a paramount role of the dopaminergic s…
Background While a large amount of medical literature has explored the association between Attention Deficit/Hyperactivity Disorder (ADHD) and Substance Use Disorders (SUDs), less attention has been dedicated to the typologies of SUD and their relationships with ADHD-specific symptomatology and general psychopathology in dual disorder patients. Methods We selected 72 patients (aged 18-65) with a concomitant SUD ou…
Traumatic brain injury (TBI) is a frequent cause of chronic headache, fatigue, insomnia, hyperactivity, memory deficits, irritability and posttraumatic stress disorder. Recent evidence suggests beneficial effects of pro-cannabinoid treatments. We assessed in mice levels of endocannabinoids in association with the occurrence and persistence of comparable sequelae after controlled cortical impact in mice using a set…
BACKGROUND: Adult attention deficit hyperactivity disorder (ADHD) shows a robust association with alcohol and cannabis misuse, and these relationships are expressed differently in males and females. Manifestation of specific ADHD symptom profiles, even in the absence of the full disorder, may also be related to problems with alcohol and cannabis, although these relationships have not been investigated in epidemiol…
