Seizures are a possible side effect after brain surgery, says MedlinePlus. Besides seizures, a patient can also suffer from blood clots, strokes, coma, brain swelling or infection in the brain, around the surgical wound or in the skull.
Patients who undergo brain surgery are also subject to clumsiness, muscle weakness, difficulties in memory and speech, vision problems and other maladies, claims MedlinePlus. These effects may disappear, or they may be permanent.
Despite these risks, patients need to have brain surgery for a variety of reasons, says MedlinePlus. These include brain tumor, blood clots or bleeding in the brain, weak or abnormal blood vessels in the brain, infections of the brain, epilepsy and brain infections.
