A to Z Symptom: Seizure

May also be called: Febrile Seizures; Absence Seizures; Tonic-Clonic Seizures; Petit Mal Seizures; Grand Mal Seizures

More to Know

"Seizure" is a general term that refers to sudden abnormal electrical discharges in the brain that can cause someone to collapse, convulse, or have another temporary disturbance of normal brain function, often with a loss or change in consciousness.


There are different types of seizures, with different causes and treatments.


If epilepsy is suspected, the doctor will order medical tests, including an electroencephalogram (EEG) to measure brain wave activity.

Keep in Mind

While absence seizures do not look as serious as some other types of seizures, they can be dangerous if, for example, they occur during swimming, bathing, or driving. Someone who has them should never swim, ride a bicycle, or drive alone.
