Overview

Epilepsy is a chronic neurological disorder characterized by recurrent, unprovoked seizures. Seizures occur when the brain experiences sudden bursts of abnormal electrical activity, which can affect movement, behavior, awareness, or sensations. Seizures caused by epilepsy are sudden and unpredictable; there are no prior symptoms. Epilepsy can affect people of all age groups and may be caused by genetic factors, brain injury, infections, or unknown causes. Some patients experience frequent seizures, while others may have long seizure-free periods; there is no predictable pattern. Although epilepsy is a long-term condition, many people are able to manage it effectively with proper medical care and lead active and fulfilling lives.

Symptoms
Symptoms of epilepsy vary depending on the type of seizure. They may include brief staring spells, uncontrollable jerking movements of the arms or legs, loss of consciousness, confusion, fear, or unusual sensations such as tingling or flashing lights. After a seizure, a person may feel tired, confused, or have a headache. Most of the seizures last between 30 seconds and 2 minutes. If a seizure lasts more than 5 minutes, it is strongly advised to visit your nearest healthcare facility.

Causes
Epilepsy may be caused by genetic factors, head injury, stroke, brain tumours, infections such as meningitis, or lack of oxygen during birth. In many cases, no clear cause is identified. Structural changes in the brain or abnormal brain development can also increase the risk of developing epilepsy.

Diagnosis
Diagnosis is based on medical history, detailed description of seizure events, and neurological examination. An electroencephalogram (EEG) is commonly used to detect abnormal electrical activity in the brain. Additional Imaging tests, such as MRI or CT scans, help identify structural brain abnormalities that may be causing seizures.

Treatment
Epilepsy is mainly treated with anti-seizure medications, which help control abnormal brain activity and prevent seizures. Many patients achieve good seizure control with the right medication and dosage. If medications are ineffective, other options include special diets, nerve stimulation devices, or surgery to remove the seizure-causing area of the brain. Lifestyle measures such as adequate sleep, stress management, and avoiding seizure triggers are also important. With consistent treatment and follow-up, most people with epilepsy can significantly reduce seizure frequency.
