The manifestations of obsessive-compulsive disorder (OCD) may vary across cultures. This is article discusses six case presentations of Arabic Muslim people suffering from OCD and is closely associated with practising religious rituals which tend to dominate the clinical picture. This is particularly relevant to sensory phenomena, which are often perceived as abnormal perceptions or hallucinations. We conclude that these phenomena are not uncommon in OCD and have relevant cultural, diagnostic and therapeutic issues in some cases.
Background: High rates of history of childhood attention deficit hyperactivity disorder (ADHD) symptoms have been found in obsessive-compulsive disorder (OCD) adults. Both, when comorbid, cause the clinical course to be unfavorable, more susceptibility to substance use, and a bad response to treatment. We planned to assess the impact of childhood ADHD symptoms on OCD adults and the effect of this on clinical characteristics and comorbidities of the disorder. Results: Our cross-sectional investigation uncovered that 44% of the OCD patients had childhood ADHD symptoms. Patients with childhood ADHD manifestations with at present grown-up ADHD had more elevated amounts of depression, anxiety, and impulsiveness. OCD patients with child ADHD symptoms but not continued symptoms till adulthood versus those without child ADHD symptoms had higher levels of depression, anxiety, and impulsiveness and more severe OCD symptoms. Conclusion: ADHD in adults with OCD is associated with some features impairing the clinical picture including higher levels of anxiety, depression, and impulsiveness reflecting more chronic illness. A childhood history of ADHD symptoms, even if not continued till adulthood, caused more impulsiveness, more severe OCD symptoms, and more anxiety and depression comorbidity.
Background: Executive function (EF) domain deficits which most reported include in particular set shifting and inhibition, which are considered main deficits in obsessive-compulsive disorder (OCD). So, this research aimed to assess EF in patients with a primary diagnosis of OCD in comparison to a healthy control group; in order to understand the impaction of this disorder on the patient's neuropsychological status. Results: There was no significant difference between OCD patients and controls regarding demographic characteristics. Average duration of illness in OCD group was 3.97 ± 5.08 years. Forty patients (60.6%) had OCD medication prior to the study. Depression was the most prevalent comorbidity among OCD group (36.4%) then anxiety (12.1%) and social anxiety (3%). Regarding WCST indices, a significant difference (P < 0.05) was found between both groups in total number of correct answers, total number of errors, mean of errors, total number of perseverative errors, mean of perseverative errors, total number of non-perseverative errors, mean of nonperseverative errors, and conceptual level responses without significant difference (P ≥ 0.05) in the remaining indices. In ToL indices, there was highly significant difference (P < 0.001) between both groups regarding total time, but not regarding total moves (P ≥ 0.05). The defect in EF was positively correlated to the severity of symptoms of OCD. There was no significant difference between patients who had been receiving medical treatment and those who had not, also between patients who had comorbidities accompanying OCD and those who had not regarding EF as evident by both WCST measured parameters and TOL parameters. Conclusions: OCD patients appear to have EF deficits in the fields of set-shifting, inhibitory control, working memory, and planning ability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
