Depression and Anxiety in Patients with Epilepsy

The aim of this investigation was to study the interaction between depression/anxiety and epilepsy. One hundred fifty individuals with partial epilepsy, 70 with idiopathic generalized epilepsy, and 100 controls were administered two self-rating mood questionnaires (Zung and Stai) for the evaluation of depression and anxiety, respectively. The group with epilepsy was much more severely impaired than the controls according to both mood questionnaires; the patients with partial epilepsy, especially those with temporal lobe epilepsy (TLE), were more depressed and anxious than the patients with generalized epilepsy. The group with left TLE appeared to have the highest levels of depression and anxiety. The final results of our study confirmed that some mood disorders are common throughout the epilepsy population, especially in patients with left TLE. No correlation was noted between the frequency of seizures and onset of epilepsy and the results of the mood questionnaires. Moreover, no differences were found in depression and anxiety between males and females among both left focus and right focus epilepsy patients
