Epilepsy is a chronic neurological disorder characterized by recurrent, unprovoked seizures caused by abnormal electrical activity in the brain. Seizures can vary widely in presentation, ranging from brief lapses in awareness or staring spells to convulsions with muscle stiffness, jerking movements, or loss of consciousness. The condition may result from genetic factors, brain injury, infections, stroke, tumors, or developmental disorders, though in many cases the exact cause is unknown. Diagnosis typically involves medical history, neurological examination, and tests such as electroencephalography (EEG) and brain imaging. While epilepsy cannot always be cured, it is often effectively managed with anti-seizure medications, lifestyle adjustments, and, in certain cases, surgery or specialized therapies to reduce seizure frequency and improve quality of life.
