The Kashmir Valley is a chronic conflict zone with a community prevalence of post traumatic stress disorder of 15.9%. The present study was conducted with the aim to find the psychiatric co-morbidity in patients suffering from Post Traumatic Stress Disorder seeking treatment at Government Psychiatric Diseases Hospital Srinagar, Kashmir India.

Sample comprised of 100 consecutive cases of post traumatic stress disorder (PTSD) with an age group of 16 -65 years diagnosed according to DSM - IV laid criteria. Patients with a prior history of any DSM-IV Axis- I or Axis- II disorder before the development of PTSD were excluded from the study. A detailed semi structured interview with all relevant items from MINI PLUS (MINI International Neuropsychiatric Interview based on DSM - IV), was administered to all the cases included in the study to find the co-morbidity.

Psychiatric Co-morbidity was highly prevalent in patients of Post Traumatic stress Disorder in our study. Major Depressive disorder (80%) formed the commonest co morbidity followed by Panic Disorder (32%), substance abuse and conversion disorder (16% each). Other co-morbidities include agoraphobia (8%), generalized anxiety disorder (8%), obsessive compulsive disorder (4%).

Post Traumatic Stress Disorder is a complex disorder with high prevalence of co-morbidity. The classification of PTSD as anxiety disorder with overlap in the mood disorders needs to be further studied.
