Neuropsychological performance in youth with obsessive-compulsive disorder.

There is a paucity of literature on neuropsychological functions in youth with obsessive-compulsive disorder (OCD). Most studies have small sample sizes and have yielded inconsistent results. A recent meta-analysis failed to identify any significant impairments. We studied neuropsychological functions (attention, verbal fluency, working memory, set-shifting, response inhibition, planning and visuospatial abilities) in a large sample of youth with OCD (n = 97) in comparison with controls who did not have OCD (n = 50). After controlling for the confounding effects (age, sex, severity of depression and anxiety, presence of comorbid attention-deficit hyperactivity disorder, any tic disorder, number of comorbidities, and non-verbal intelligence measured by the standard progressive matrices), the youth with OCD significantly underperformed with large effect sizes compared to controls, only on the test of 'behavioral reversal', measured by the Object Alternation Test (trials to reach criterion p < 0.001, Cohen's d = 1.49; perseverative errors p < 0.001, Cohen's d = 1.31). Patients also underperformed on a task of planning, but it was statistically insignificant. Certain comorbid disorders, antipsychotic use and age of onset did not influence neuropsychological performance significantly. Our study demonstrates that youth with OCD may have impaired 'set-shifting' in the form of 'behavioral reversal' and possibly planning, findings broadly consistent with the literature in adults and with the fronto-striatal model of OCD. It is possible that youth may accumulate more neuropsychological impairments over a period, as the illness continues into adulthood.

Specific learning disability in the context of current diagnostic systems and policies in India: Implications for assessment and certification.

Specific Learning Disability (SLD) is a neurodevelopmental disorder with significant problems in language processing, which are evident through difficulties in reading, writing, spelling, and mathematics. SLD was notified as a disability by the Government of India in 2016. Until then, it was primarily left to the discretion of the individual education boards to decide the assessment procedures and support measures for a child suspected to have SLD. However, with the enforcement of the Rights of Persons with Disabilities Act 2016 (RPWD Act), there is a legal binding to follow specific guidelines for assessment and certification mentioned in the RPWD Act. Nonetheless, there are issues inherent to the construct of SLD described in the diagnostic manuals and the current certification processes under the RPWD Act. In this context, this paper highlights the discrepancies in the requirements of the RPWD Act and the diagnostic criteria of the International Classification of Diseases -10 (ICD-10) and the Diagnostic and Statistical Manual- 5 (DSM-5) and draws implications for assessment and certification procedures which will affect the lives of millions of children in the Indian context. It also presents potential solutions and possible future directions related to the assessment of the SLD.
