Disability in Person with Schizophrenia: Its Correlation with Psychopathology and Socio-Demographic Profile.

Schizophrenia causes considerable functional disability. The present study was designed to assess disability in person with schizophrenia and to see its relationship with psychopathology (PANNS score), UKU side effect, duration of illness, duration of treatment, perceived social support and other socio-demographic factors . The study was done at the Institute of Post Graduate Medical Education & Research (IPGMER), Kolkata, India. For this study 100 patients with a clinical diagnosis of schizophrenia as per ICD-10 were taken. Thereafter, all patients were assessed on Positive and Negative Syndrome Scale for Schizophrenia (PANSS) for psychopathology, on Indian Disability Evaluation Assessment Schedule (IDEA) for disability, on UKU Side Effect Rating Scale for side effects of drugs and on Social Support Questionnaire (SSQ) for perceived social support. It was found that majority of the patients were having severe level of disability in global, interpersonal activity and communication & understanding area and moderate level in work and self care domains. PANSS total score had a significant (<0.035) positive correlation and SSQ total score had a significant (p<0.000) negative correlation with global disability. Age of onset, duration of illness have an effect on disability. The total score of PANSS and SSQ SERS total score emerged as the sole significant predictor of global disability. Treatment in schizophrenia should be focused on psychopathology and social support system to improve competencies in retaining an occupation, better interpersonal relationship with co-workers, and significant others.

A study of sleeping disorders in blind patients.

An internal 24-hour biological clock working in tandem with external environmental cues like bright light regulates our daily rhythms specially sleep-wake cycle. In a blind individual, due to absence of external cue endogenous rhythm may take upper hand and free running of sleep-wake cycle starts without any synchronicity with day-night cycle, creating ground for sleep disorders. To evaluate the frequency of sleep disorders, 65 blind individuals without any comorbid medical or surgical problem were interviewed according to the criteria of Diagnostic and Statistical Manual of Mental Disorder-IV (DSM-IV). Simultaneously 70 persons with no visual impairment were assessed in the same manner as used for blind persons. Blind patients showed far higher presence (44.6%) of sleep problems compared to controls (15.7%), and this difference was highly significant statistically [odd's ratio (OR) = 4.32, CI 95 =1.8-10.54]. Blind patients showed far higher presence (43.1%) of DSM-IV based diagnosis compared to controls (8.6%), and this difference was highly significant statistically [OR = 8.072, CI 95 = 3.059-21.298]. Circadian sleep disorders, insomnia and hypersomnia were relatively higher in blind patients. High incidence of sleep disorders calls for development of short reliable screener for sleep disorders among blind persons and better liaison among ophthalmologists and psychiatrists for early detection of this problem.
