A seizure is a sudden, uncontrolled electrical disturbance in the brain. It can cause changes in behavior, movements, and feelings. Seizures can be caused by a variety of factors, including epilepsy, head injuries, and infections.
Types of Seizures
There are two main types of seizures:
Focal seizures
These seizures start in one part of the brain and can cause changes in behavior, movements, and feelings.
Generalized seizures
These seizures affect the entire brain and can cause loss of consciousness, convulsions, and other symptoms.
Causes of Seizures
Seizures can be caused by a variety of factors, including:
Epilepsy
Epilepsy is a condition that causes seizures. It can be caused by a variety of factors, including genetics, brain injuries, and infections.
Head injuries
Head injuries can cause seizures, especially if they damage the brain.
Infections
Infections such as meningitis can cause seizures.
Brain tumors
Brain tumors can cause seizures, especially if they press on the brain.
Medications
Some medications can cause seizures as a side effect.

- Taking medications as prescribed
- Getting enough sleep
- Avoiding alcohol and drugs
- Managing stress
- Wearing a helmet during activities that could cause head injuries
