Generalized seizures
Generalized Seizures
Generalized seizures (/ˈdʒɛnərəˌlaɪzd ˈsiːʒərz/), also known as grand mal seizures, are a type of seizure that affects both sides of the brain or groups of cells on both sides of the brain at the same time. This term is used to describe a seizure that appears to involve all areas of the brain.
Etymology
The term "generalized" comes from the Latin word "generalis", meaning "relating to all, universal". "Seizure" is derived from the Old French "saisir", meaning "to take hold of" or "to grasp".
Types of Generalized Seizures
There are several types of generalized seizures, including:
- Tonic-clonic seizures - These seizures cause a mixture of symptoms, including stiffening of the body and repeated jerks of the arms and legs.
- Absence seizures - These seizures are characterized by a short loss of consciousness, with few or no other symptoms.
- Myoclonic seizures - These seizures cause quick, jerking movements of the muscles.
- Atonic seizures - Also known as drop seizures, these cause a loss of muscle control, which may cause sudden falls.
- Clonic seizures - These seizures are characterized by repeated, jerky muscle movements of the face, neck, and arms.
Causes
Generalized seizures can be caused by several conditions, including:
- Epilepsy - A neurological disorder that causes recurrent, unprovoked seizures.
- Brain tumor - A mass or growth of abnormal cells in the brain.
- Stroke - A condition that affects the blood supply to the brain.
- Brain injury - Damage to the brain from trauma.
Treatment
Treatment for generalized seizures typically involves medication, lifestyle changes, and in some cases, surgery. The goal of treatment is to reduce the frequency and severity of seizures, and to improve quality of life.
