A.

Chiari 1 malformations are usually asymptomatic, meaning that it is found on an MRI done for unrelated reasons. A Chiari 1 malformation is the shifting of a small amount of the cerebellum down below the base of the skull. When severe, it can be associated with headaches and upper extremity weakness. But, in the great majority of cases it does not cause any symptoms. So, you should be very reluctant to have surgery for a Chiari malformation unless multiple physicians agree that it is appropriate.

In addition, Chiari 1 is not associated with seizures. Seizures arise from the cortex over the two cerebral hemispheres. Seizures do not arise from the base of the brain that is involved with the Chiari malformation.

To avoid having another seizure, it's important to work with your doctor to adjust the anti-seizure medicines to lessen the risk of recurrent seizures.
