Serious Warning Signs Of A Cavernous Malformation

Seizures

Seizures are another neurological symptom that can indicate a cavernous malformation. While the most noticeable seizures are often clear signs of a medical emergency, certain types of seizures can go unnoticed. Seizure activity occurs when the brain sets off abnormal electrical impulses, which can occur as a result of accumulating pockets of blood or a more heavy bleed. Generalized seizures are seizures that occur when both hemispheres of the brain experience abnormal activity. Focal seizures occur when only a certain portion of the brain is affected. The most recognizable type of seizure is a generalized tonic-clonic seizure, formerly called a grand mal. During a tonic-clonic seizure, the patient loses consciousness, experiences stiffening of the muscles, and falls to the ground with spastic and jerking movements. A typical tonic-clonic seizure lasts between one and three minutes. If individuals don't have a diagnosed seizure disorder, a seizure is always a medical emergency.
