What are the causes of seizures?
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
