The effects of epilepsy and its treatments on affect and emotion.
Epilepsy creates significant morbidity, disability, and loss of productivity worldwide. Although unpredictable seizures define epilepsy, the cognitive and emotional difficulties encountered by people with epilepsy may have an even greater impact on everyday function. Epilepsy is associated with lower quality of life (QOL); while this is partially attributable to ongoing seizures, QOL is independently affected by comorbid affective disorders like depression and anxiety. These can accompany all types of epilepsy, but may be especially noteworthy in partial epilepsy syndromes with foci in the frontal or temporal lobes. There is growing evidence that epileptogenic lesions disrupt cortical networks that carry out emotional processing. In addition to epilepsy itself, treatment strategies also affect cognitive functioning and mood. Antiepileptic drugs, vagal nerve stimulation, and surgical resection have all been associated with changes in mood, emotional processing, and social cognition. Overall, the relationship between epilepsy and emotion is vastly complex; when assessing emotional difficulties in a person with epilepsy, we must consider the psychosocial impact of the disease on the patient, the underlying pathophysiology of the disease, and the effects of ongoing treatments.
