We sought to study characteristics of patients presenting with psychogenic non-epileptic seizures (PNES), with and without major psychiatric comorbidity. A total of 39 patients who were diagnosed with PNES in a tertiary care setting were studied, and those patients with and without axis I psychiatric disorders in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) were compared. The mean time in confirming the diagnosis was 9 years. More than half the patients were taking anti-epileptic medications when they presented for video-electroencephalographic monitoring. The mean monitoring time required to capture a PNES was 0.6 days. Comorbid chronic medical conditions were found in 38.5% and axis I-psychiatric diagnoses in 48.7%. There were no significant differences in characteristics between those with and without major psychiatric comorbidities.
