Prevalence of Psychopathology in Dutch Epilepsy Inpatients: A Comparative Study

Area of Science:

• Neurology
• Psychiatry
• Epidemiology

Background:

• Epilepsy is a chronic neurological disorder associated with various comorbidities.
• Psychiatric disorders are frequently observed in epilepsy patients, impacting quality of life.
• Understanding the prevalence of these comorbidities is crucial for comprehensive patient care.

Purpose of the Study:

• To determine the prevalence of psychiatric disorders in Dutch epilepsy patients.
• To compare this prevalence with epidemiological data from the general Dutch population.
• To investigate potential differences in psychiatric disorder prevalence between temporal lobe epilepsy (TLE) and extra-temporal lobe epilepsy (extra-TLE).

Main Methods:

• A cohort of 209 epilepsy patients was assessed.
• The Composite International Diagnostic Interview (CIDI) was utilized for psychiatric disorder assessment.
• Prevalence data were compared between epilepsy patients and a representative sample of the general Dutch population.

Main Results:

• Anxiety and mood disorders were the most common psychiatric conditions in epilepsy patients.
• The last-year prevalence was 25% for anxiety disorders and 19% for mood disorders.
• Epilepsy patients exhibited a significantly higher prevalence of anxiety and mood disorders than the general population. No differences were observed between TLE and extra-TLE.

Conclusions:

• Dutch patients with epilepsy, particularly those attending a tertiary epilepsy center, have a higher burden of mood and anxiety disorders.
• These findings underscore the need for integrated psychiatric care within epilepsy management.
• Further research may explore underlying mechanisms and targeted interventions for these comorbidities.
