Risk Factors for Epilepsy

A risk factor is something that increases your likelihood of getting a disease or condition. It is possible to develop epilepsy with or without the risk factors listed below. However, the more risk factors you have, the greater your likelihood of developing epilepsy. If you have a number of risk factors, ask your doctor what you can do to reduce your risk.

Risk factors for epilepsy include:

Any injury to the brain, either from external (environmental) or internal (medical/metabolic) sources can increase your risk of epilepsy.

Side View of the Brain

Brain injury can be caused by:

Head injury
Stroke
Alzheimer’s disease
Tumors (primary or metastatic)
