Epilepsy is a neurological disorder that affects the brain's electrical activity and can cause seizures or convulsions. These seizures can vary in severity and duration, ranging from momentary lapses of awareness to full-body convulsions that last several minutes.

There are many different types of epilepsy, each with its own set of symptoms and triggers. Common triggers for seizures include stress, lack of sleep, flashing lights, and certain medications.

Epilepsy can be caused by a variety of factors, including genetics, brain injury, infections, and developmental disorders. In some cases, the cause may not be known.

Diagnosis of epilepsy typically involves a comprehensive medical evaluation, including medical history, physical examination, and diagnostic tests such as electroencephalography (EEG) and magnetic resonance imaging (MRI).
