AbstractDifferent genetic polymorphisms in the SLC1A1 have been shown to be associated with obsessive-compulsive disorder. Rs301430 is a T/C functional polymorphism affecting the gene expression and extrasynaptic glutamate concentration.We observed that Rs301430 influence age at onset in obsessive-compulsive disorder.

ABSTRACTIntroduction: Research suggests that obsessive-compulsive disorder (OCD) is not a unitary entity, but rather a highly heterogeneous condition, with complex and variable clinical manifestations.Objective: The aims of this study were to compare clinical and demographic characteristics of OCD patients with early and late age of onset of obsessive-compulsive symptoms (OCS); and to compare the same features in early onset OCD with and without tics. The independent impact of age at onset and presence of tics on comorbidity patterns was investigated.Methods: Three hundred and thirty consecutive outpatients meeting Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for OCD were evaluated: 160 patients belonged to the “early onset” group (EOG): before 11 years of age, 75 patients hadResults: The EOG had a predominance of males, higher frequency of family history of OCS, higher mean scores on the “aggression/violence” and “miscellaneous” dimensions, and higher mean global DY-BOCS scores. Patients with EOG without tic disorders presented higher mean global DY-BOCS scores and higher mean scores in the “contamination/cleaning” dimension.Conclusion: The current results disentangle some of the clinical overlap between early onset OCD with and without tics.

Bdnf Rs6265

Brain-derived neurotrophic factor (BDNF) is the most abundant neurotrophin in the central nervous system and was shown to be involved in neuronal growth, differentiation and synaptic plasticity. A single nucleotide polymorphism at the pro-region of the BDNF gene (rs6265) has been reported to alter the amino acid from valine to methionine at codon 66 and was associated with neuropsychiatric disorders in several studies. To date, the results on the association of BDNF rs6265 to the aetiology of the neuropsychiatric illnesses have been inconsistent with some studies reporting a positive association and others reporting no association. Concerning the past inconsistent reports, this mini-review aims at determining the association of BDNF rs6265 and neuropsychiatric disorders among the different studies. Firstly, we discuss the findings on studies reporting the association of BDNF rs6265 with depression whereby a positive association between the BDNF variant and depression was obtained in several studies on the Caucasian, German, Chinese, and Malaysian population but not in studies on the Korean and other populations. Likewise, some studies found the occurrence of the SNP to be associated with a reduction in the BDNF level in depressed cases, but others found no effect at all. We then reported findings on the association of BDNF rs6265 with anxiety disorder, post-traumatic stress disorder, obsessive-compulsive disorder, panic disorder, bipolar disorder, and schizophrenia. Val allele has been found associated with these disorders, whereas some studies reported the involvement of the Met allele, and some reported no association at all. Similarly, the association of the BDNF variant with the BDNF level remains controversial. It is, therefore, essential to conduct more studies with larger sample sizes and look at the haplotype level to determine the association.

ABSTRACTIntroduction: Evidence from phenomenological, family, genetic, and treatment studies from Western centers have suggested that tic-related obsessive-compulsive disorder (OCD) could be different from non-tic-related OCD. This study from India investigated the differences in OCD with and without tics, with respect to sociode-mographics, symptom profile, and comorbidity, including obsessive-compulsive spectrum disorders, to examine whether the clinical profile of tic-related OCD is similar to that reported previously.Methods: Fifty subjects with OCD and tics (chronic motor tics and Tourette syndrome) were compared with 141 OCD subjects without tics.Results: Subjects having OCD with tics tended to be males, and had an earlier onset of illness. They had more of symmetry/aggressive and religious obsessions, and cleaning, ordering/arranging, hoarding, and repeating compulsions and were associated with trichotillomania and hypochondraisis. Stepwise backward (Wald) regression analysis showed that an early age of onset, male gender, aggressive obsessions, cleaning compulsions, and trichotillomania were significantly associated with tic-related OCD.Conclusion: The findings of this study from India are broadly similar to those reported previously from the West indicating the universality of differences in tic- and non-tic-related OCD. Our findings also support the existing evidence that tics contribute to the heterogeneity of OCD.

Background: Obsessive compulsive disorder (OCD) is a common and potentially debilitating disorder. Neuropsychological assessment provides unique complementary information that is critical for evaluating higher cortical abilities. This study aimed to assess the neuropsychological functions in OCD patients which can then point to the brain structures or pathways and to study the correlation between these assessments and different clinical variables. Methods: This cross-sectional case control study had included sixty patients who were divided into two groups, Group I: thirty OCD patients diagnosed by DSM-IV and Group II: thirty healthy controls who were recruited from the community, matched with patients’ age, gender, and education. Results: The age of onset in our study was 19.13 ± 0.35 years, the mean duration was 7.44 ± 3.88 years, 40% of the studied cases had severe OCD symptoms and 33.3% of them were compulsive cleaners. There was a high significant difference between the two groups regarding WCST in favor of the control group. There was a high significant difference between the two groups regarding ROCF where the control group showed better results than the OCD patients. Conclusions: Neuropsychological test performance remains an informative and objective means of investigation, especially when applied to psychiatric disorders. The executive functions in OCD patients were impaired in comparison to the normal study subjects.

Introduction: Patients with Gilles de la Tourette syndrome (GTS) may experience blocking tics (BTs) defined as recurrent, brief cessations of motor acts. The aim of this study was to assess the prevalence, age of onset, and clinical correlates of BTs in GTS patients.Materials and Methods: We performed a one-time registration study in a cohort of 195 consecutive GTS patients aged 5–66 years (mean age: 15.0 ± 9.2; 47 females, 24.1%). All patients were personally interviewed and examined.Results: At least one BT occurred at some point in the lifetime of 73 patients (37.4%) with a mean age of onset of 10.4 ± 5.9 years. BTs occurred an average of 4.8 ± 5.3 years after tic onset. The most common BT was cessation of walking (n = 59, 80.8%), followed by speech (n = 19, 26.0%), running (n = 18, 24.7%), and writing (n = 9, 12.3%). Most of the patients (n = 52, 71.2%) reported cessation of only one activity. Clinical associations of BTs included more severe tics, overall greater number of tics, and, to a lesser extent, higher age at evaluation and comorbid obsessive-compulsive disorder.Conclusions: BTs represent complex tics, early and common symptoms of GTS, and are associated with a more severe form of GTS.
