Dad had meningioma removed (1 1/2 yrs ago). still gets occasional seizures, and has weakness in left side. taking meds, done pt. why still an issue?

Meningioma: Meningiomas arise from the meninges and compress the underlying brain. The irritation of the underlying brain can persist even after the meningioma is removed and lead to seizures and epilepsy. After a seizure, the body opposite to the side of the seizure is often weak (Todd's paralysis). Additional seizure medications may be needed as well as an evaluation with a rehab physician (physiatrist).

He likely has residual areas of gliosis (scarring) secondary to local damage to brain tissues, and this area has become a site for epileptic activity. If the weakness is chronic, this too is due to the tumor. Physical therapy may help. Modification of anti-seizure medicines should also help. See a neurologist and get all of this handled.
