Epilepsy Specialists in Tamil Nadu

What is Epilepsy?

Epilepsy is a chronic neurological disorder characterised by a tendency to have recurrent, unprovoked seizures, which result from sudden, abnormal bursts of electrical activity in the brain. A single seizure does not necessarily mean a person has epilepsy, but the condition is generally diagnosed after two or more unprovoked seizures occurring more than 24 hours apart. Seizures can vary widely in presentation, ranging from brief lapses in awareness to convulsions involving the entire body, depending on which area and how much of the brain is affected by the abnormal electrical activity. Epilepsy can develop at any age and from a wide range of causes, though in a substantial proportion of cases no specific underlying cause is identified. With appropriate treatment, the majority of people with epilepsy achieve good seizure control and are able to lead full, active lives, though the condition requires ongoing management and certain lifestyle precautions.

Causes of Epilepsy

Causes include genetic factors, brain injury from trauma, stroke, or infection, structural brain abnormalities, and certain developmental conditions, though in a significant proportion of cases no specific cause is ever identified. Prior severe head injury, brain infections such as meningitis or encephalitis, and stroke are among the more commonly identified causes in adults. Family history of epilepsy increases risk, reflecting a genetic contribution to susceptibility in many cases.

Symptoms of Epilepsy

Sudden convulsions or muscle jerking, temporary confusion or loss of awareness, staring spells, unusual sensations such as strange smells or tastes preceding a seizure, temporary loss of consciousness, stiffening of the body, uncontrolled movements, in some cases loss of bladder or bowel control during a seizure

Treatment & Types of Epilepsy in Tamil Nadu

Treatment primarily involves antiseizure medications, with the specific choice guided by the type of seizure and individual patient factors, aiming to control seizures with the fewest possible side effects. For the minority of patients whose seizures do not respond adequately to medication, options such as specialised diets, nerve stimulation devices, or surgery to remove the specific area of the brain causing seizures may be considered. Regular follow-up with a neurologist helps monitor treatment effectiveness and adjust medication as needed over time.

Epilepsy is broadly classified into focal seizures, starting in one area of the brain and sometimes spreading, and generalised seizures, involving both sides of the brain from the onset, such as tonic-clonic (convulsive) or absence (brief staring) seizures. It is also categorized by cause as structural, genetic, infectious, metabolic, immune, or of unknown cause, which helps guide the choice of antiseizure medication and further evaluation.
