Background : Alcohol is a ordinary commodity, used since time immemorial. Psychiatric co morbidities have a high prevalence among patients of alcohol dependence and often pose challenges in their diagnosis and treatment and are found to be a major contributor to relapses. They raise a challenging question of how to provide the best integrated treatment to address both. Aim : To study the socio demographic profile and psychiatric co morbidity in patients of alcohol dependence syndrome. Objectives: 1. To study the socio demographic profile of alcohol dependence patients 2. To determine the prevalence and type of psychiatric co–morbidity in alcohol dependent patients. Methodology : A consecutive sample of 100 Alcohol Dependence Syndrome patients attending outpatient were selected. A questionnaire was administered to collect sample and alcohol dependence characteristics. psychiatric co–morbidity evaluation was done using Mini International Neuropsychiatric Interview (MINI Plus) and the diagnosis was confirmed by using ICD–10. Results : Majority of the subjects were young adults with a mean age of 42 years, were illiterates, married, employed, belonged to rural background and from lower socio–economic status. psychiatric co–morbidities were present in 33% of population. More of affective spectrum (18%) as compared with lesser numbers of patients in the anxiety (11%) or psychotic spectrum (4%). psychiatric co–morbidity is significantly greater in those who are unemployed. Conclusions: The psychiatric co–morbidity was present in 33% of the population studied. More of affective spectrum, followed by anxiety spectrum and less number of them in psychotic spectrum. All psychiatric co–morbidities may need to be identified for patients diagnosed as alcohol dependence who present with longer duration of drinking and unemployed for effective and comprehensive management.
