The World Health Organisation states that there are various mechanisms through which epilepsy can occur and the exact etiology is still unknown in about 50% of the global cases.
There can be different causes of epilepsy. An imbalance of neurotransmitters or the nerve-signaling chemicals, congenital abnormalities, trauma or head injury, genetic conditions, prenatal or perinatal brain damage, stroke, brain tumor, brain infection in diseases such as meningitis, encephalitis or neurocysticercosis, etc., are some of the causes.
Certain risk factors for epilepsy include cerebral palsy, brain tumours, Alzheimer’s disease, Autism spectrum disorder, use of illegal drugs such as cocaine, etc.
It is important to note that every condition mentioned above does not necessarily leads to epilepsy. Epilepsy is known to occur more often in these conditions than in their absence.
