Epilepsy is a chronic neurological condition characterised by recurrent seizures resulting from abnormal electrical activity in the brain. It affects people of all ages and arises from a range of causes, including genetic predispositions, brain injuries, infections such as meningitis or encephalitis, and developmental disorders. In more than half of cases, no clear cause is identified.
Seizures are broadly classified as focal, beginning in one area of the brain, or generalised, involving both hemispheres from the outset. Focal seizures may preserve or impair awareness, while generalised seizures typically cause loss of consciousness and affect the whole body. Common subtypes include tonic-clonic seizures, absence seizures, myoclonic seizures, and atonic seizures, each with distinct presentations and management considerations.
Diagnosis typically involves a detailed medical history and electroencephalogram (EEG). Treatment is tailored to seizure type, age, and overall health. Antiseizure medications, such as levetiracetam, lamotrigine, or valproate, are the first line of management. For those who do not respond adequately, options include surgery, vagus nerve stimulation, responsive neurostimulation, or deep brain stimulation. Dietary approaches such as the ketogenic diet may provide additional support in select cases.
Lifestyle factors, including consistent sleep, stress management, and avoiding known triggers, also contribute to seizure control. Practical planning, including seizure action plans and regular clinical follow-up, supports safety and independence in daily life.
