What it is
Epilepsy is a brain disorder that causes recurring seizures. A seizure happens when clusters of nerve cells (neurons) in the brain send out the wrong signals.
What a seizure can look like
During a seizure, a person may:
- have strange sensations or emotions;
- behave strangely;
- have violent muscle spasms;
- lose consciousness.
Causes
Epilepsy has many possible causes, including:
- illness;
- brain injury;
- abnormal brain development.
In many cases, the cause is unknown.
Diagnosis
Doctors use brain scans and other tests to diagnose epilepsy. Starting treatment right away is important.
Treatment
There is no cure, but medicines control seizures for most people. When medicines don't work well:
- surgery may help;
- so may implanted devices, such as vagus nerve stimulators.
Special diets can help some children with epilepsy.
