Focal seizures

The prevention of focal seizure development involves avoiding insults or injury to the brain; for example, wearing protective headgear in sports (helmets) and other physical activities (bicycle riding) will reduce the incidence and severity of traumatic brain injury.

Taking appropriate precautions to avoid central nervous system (CNS) infections (e.g., meningoencephalitis) by vaccination may be considered to be preventive. In addition, avoiding or limiting alcohol intake, and abstaining from recreational drug use, should reduce the risk of CNS injury.
