Nerve cells (neurons) in the brain create, send and receive electrical impulses, which allow the brain's nerve cells to communicate. Anything that disrupts these communication pathways can lead to a seizure.
Epilepsy is the most common cause of seizures
. But not every person who has a seizure has epilepsy. Sometimes seizures happen because of:
- High fever, which can be associated with an infection such as meningitis
- Lack of sleep
- Low blood sodium (hyponatremia), which can happen with diuretic therapy
- Head trauma that causes an area of bleeding in the brain
- Brain tumor
- Illegal or recreational drugs, such as amphetamines or cocaine
- Alcohol abuse, during times of withdrawal or extreme intoxication
