Epilepsy is a neurological disorder marked by sudden recurrent episodes of sensory disturbance, loss of consciousness, or convulsions, associated with abnormal electrical activity in the brain. Stress can cause problems sleeping which is also a seizure trigger. Chronic stress can lead to anxiety or depression. Sleep problems are symptoms of these mood problems. Being anxious and depressed can also worsen stress, causing a vicious cycle with more seizures and mood problems.  Othello has a seizure on stage, preceded by extreme emotional agitation, thus raising the issue of whether emotions can trigger seizures.
