Epilepsy and psychiatric disturbance. A cross-sectional study

Area of Science:

• Neurology
• Psychiatry
• Clinical Psychology

Background:

• Cryptogenic epilepsy affects individuals with normal cognitive function.
• Understanding the psychiatric comorbidity in epilepsy is crucial for comprehensive patient care.
• Previous research has indicated potential links between epilepsy and mental health disorders.

Purpose of the Study:

• To investigate the prevalence of psychiatric disorders in patients with cryptogenic epilepsy and normal intelligence.
• To compare psychiatric diagnoses in epilepsy patients with age- and sex-matched controls.
• To determine if cryptogenic epilepsy with normal cognition poses an increased risk for psychiatric disturbances.

Main Methods:

• A psychiatric interview using the Clinical Interview Schedule was conducted.
• One hundred patients with cryptogenic epilepsy and normal intelligence were assessed.
• One hundred age- and sex-matched controls without neurological conditions were included for comparison.

Main Results:

• Psychiatric disorders were identified in 19 patients and 15 controls.
• Anxiety and depression were the most common diagnoses in both groups.
• Personality disorders were infrequently observed in the epilepsy cohort.

Conclusions:

• Patients with cryptogenic epilepsy and normal neuropsychological abilities do not exhibit a higher risk of psychiatric disturbance compared to the general population.
• The findings challenge the assumption of increased psychiatric vulnerability solely based on epilepsy diagnosis in cognitively unimpaired individuals.
• Routine psychiatric screening may be warranted for both epilepsy patients and controls due to similar comorbidity rates.
