These SPECT images show the blood flow in the brain of a person when there's no seizure activity (left) and during a seizure (middle). The subtraction SPECT coregistered to MRI (right) helps pinpoint the area of seizure activity by overlapping the SPECT results with brain MRI results.
A seizure is a sudden burst of electrical activity in the brain. It can cause changes in behavior, movements, feelings and levels of consciousness. Epilepsy is defined as having two or more seizures at least 24 hours apart that don't have a known cause. But epilepsy doesn't cause all seizures.

Frontal lobe seizures also are known as frontal lobe epilepsy. Changes in brain tissue, infection, injury, stroke, tumors or other conditions can cause frontal lobe seizures. Medicines can help control the seizures.
Epilepsy surgery is a procedure that removes an area of the brain where seizures occur. Epilepsy surgery is most effective when seizures always occur in a single location in the brain. Epilepsy surgery is not the first line of treatment. But it might be an option when at least two anti-seizure medicines have failed to control seizures.
A febrile seizure is a convulsion in a child that's caused by a fever. The fever is often from an infection. Febrile seizures occur in young, healthy children who have normal development and haven't had any neurological symptoms before. It can be frightening when your child has a febrile seizure.
