Background: objective of the study was to describe and compare frequency of psychiatric disorders in two groups of patients, one with psychogenic non-epileptic seizures (PNESs) and other with epilepsy.

Methods: We studied 64 patients in which 32 belonged to the group with PNESs and 32 belonged to group with Epilepsy, admitted in a video-EEG unit of tertiary care hospital in Kashmir in order to confirm epileptic diagnosis. This study was conducted from March 2019 to August 2019 in neurology department and the patients underwent neurological evaluation, inter ictal EEG, MRI, neuropsychological assessment and psychiatric diagnosis codified in DSM-5.

Results: Depression was found to be the most common diagnosis in the group with epilepsy-40% versus 15.75% of those with PNES, while as personality disorder (21.88%) was the common psychiatric disorder in group with PNES. Anxiety disorder was found to be the second leading psychiatric disorder and was almost common in both the groups, 13.33% in group with epilepsy and 18.75% in the group with PNES. It was also cited that Psychotic disorder (13.33%) was found only in the group with Epilepsy, while Personality disorder and PTSD was found only in the group with PNES. Bipolar disorder was more prevalent in group with epilepsy (13.33%) than in the group with PNES (3.13%). Somatic symptom disorder, dissociation and obsessive-compulsive disorder (OCD) was also found in both the groups.

Conclusions: Psychiatric disorder is more common in PNES than in epilepsy.
