Seizures are caused by a disturbance in the electrical activity of the brain. Seizures may cause sudden changes in movement, behavior, or awareness. The symptoms typically last for 30 seconds to 2 minutes. Seizures are classified by the location of the abnormal brain activity.
Generalized seizure- Generalized seizures occur when there is abnormal brain activity on both sides of the brain. Symptoms of generalized seizure may include loss of consciousness, muscle cramping, or falls. There are six types of generalized seizure.
Epilepsy is the tendency to have recurrent seizures without provocation. However, a person may have a seizure without epilepsy.
The seizure may be caused by a stroke, brain tumor, electrolyte imbalance, head trauma, fever, sleep deprivation, medications, recreational drug use, or alcohol abuse.
An electroencephalogram (EEG) is a test that measures the electrical activity of the brain and may be used to diagnose epilepsy. Your doctor may also order imaging of the brain such as an MRI or CT scan to determine if there is a lesion or abnormality that may cause the seizure.
If a person is likely to have a repeated seizure, the condition may be treated with anti-seizure medication. If anti-seizure medication does not help other treatments such as surgery may be an option.
