[Clinical presentation, co-occurrence and suicidality in psychiatric emergency patients with psychogenic non-epileptic seizures]

Abstract

Introduction: Non-epileptic psychogenic seizures (PNES) are a common condition but little studied in psychiatry. Our study is the first Moroccan of this topic. Our aim was to describe their clinical presentation, comorbidities and suicidality.

Method: It was a one-year recruitment study conducted in the Department of Psychiatry at the University Hospital of Fez. We collected socio-demographic data. Psychometric evaluation used the MINI criteria for different psychiatric disorders, personality disorders and suicidality, the Hamilton anxiety scale, the Beck depression scale and the Childhood Trauma Questionnaire.

Results: Thirty-two patients were included, the majority of whom were female with a low economic level (89 %). The average age of onset average was 23.97 years. The generalized form represented 71.9 % of cases with a triggering factor present in 46 %. The duration of the seizures average was 23.47minutes, and 37.5 % of the patients had at least one attack per day. Among patients, 68.8 % had comorbidity: major depressive disorder MDD (46 %) and post-traumatic stress disorder PTSD (18.6 %). Suicide risk was rated as moderate or severe in 12.5 % of patients, and 40.62 % had a previous suicide attempt. A personality disorder was present in 18.8 % of cases. Finally, a history of child abuse was found in 59.4 % of patients and was correlated to PNES age of onset and co-occurrence depression.

Conclusion: We found several similarities with previous studies in terms of clinical description and co-occurrences. However, our sample is characterized by more prolonged and more frequent seizures and a higher rate of suicidality.
