IntroductionAlthough defined by the presence of tics, most patients with Gilles de la Tourette syndrome (TS) also suffer from different psychiatric disorders. While much is known about clinical characteristics of comorbidities such as attention deficit/hyperactivity disorder (ADHD), obsessive compulsive disorder (OCD), depression, and anxiety disorders, only very little is known about rage attacks. Most of this data is based on small studies in children. Until today no larger studies have been performed in adults with TS—most likely because of the lack of validated instruments. The aim of this study was to develop a ...

Abstract Olfactory dysfunction is recognized in neurodevelopmental disorders and may serve as an early indicator of global dysfunction. The present meta-analysis measures olfaction effect sizes in attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorders (ASDs), and obsessive-compulsive disorder (OCD). Meta-analysis included 320 ADHD, 346 ASD, and 208 OCD individuals as compared to 910 controls. Olfactory performance deficits were small-to-moderate and heterogeneous (d =  - 0.42, 95% CI =  - 0.59

CONCLUSIONS: The FDRs, including parents, offspring, siblings, and twins, of patients with OCD have a higher risk of OCD, schizophrenia, bipolar disorder, MDD, ADHD, and ASD. The familial co-aggregation of OCD with OCD and other major psychiatric disorders was existent in a dose-dependent manner. Given the increased risks of psychiatric disorders, medical practitioners should closely monitor the mental health of the FDRs of patients with OCD. PMID: 31907096 [PubMed - as supplied by publisher]

Publication date: 12 December 2019Source: Cell, Volume 179, Issue 7Author(s): Cross-Disorder Group of the Psychiatric Genomics ConsortiumSummaryGenetic influences on psychiatric disorders transcend diagnostic boundaries, suggesting substantial pleiotropy of contributing loci. However, the nature and mechanisms of these pleiotropic effects remain unclear. We performed analyses of 232,964 cases and 494,162 controls from genome-wide studies of anorexia nervosa, attention-deficit/hyperactivity disorder, autism spectrum disorder, bipolar disorder, major depression, obsessive-compulsive disorder, schizophrenia, and Tourette synd...

A person with attention deficit hyperactivity disorder (ADHD), mania, or obsessive-compulsive personality disorder (OCD) may be familiar with the symptoms of an...

ConclusionsThe results suggest that neuropsychological underperformance associated with OCD and ADHD may be related to the presence of comorbid disorders, such as depression, rather than disorder-specific phenomena, highlighting the importance of excluding participants with comorbid disorders in neuropsychological studies and targeting comorbidities in clinical contexts.

We examined 165 consecutive GTS patients aged 5–50 years old (75.8% males). The patients were evaluated for GTS and co-morbid mental disorders according to the DSM-IV-TR. SHB was diagnosed during the interview. To determine a direct relationship between SHB and clinical variables, we conducted two analyses, at the time of evaluation and lifetime. We also compared the group of children and adults with SHB and tried to distinguish between deliberate (non-tic related SHB) and accidental (tic related SHB). Lifetime SHB was reported by 65 patients (39.4%). In 30 of the patients (46.2%), SHB was evaluated as mild, in 26 (4...
