A type of grand mal epilepsy that typically begins with abnormal clonic movements of the thumb and forefinger, the angle of the mouth, or the big toe and spreads to include the rest of the limb and finally the other side of the body. At this point, consciousness is usually lost. Recurrent episodes of convulsive seizures or spasms without loss of consciousness localized in a part or region of the body: Named after the neurologist j. Hughlings jackson (1835–1911).
A form of epilepsy in which the jerking movements start in one part of the body before spreading to others.
Type of epilepsy characterized by recurrent motor seizure episodes that typically start as a twitching or convulsive movement of a small group of muscles and then spread to other muscles on the same side of the body as, for example, twitching of the fingers of one hand spreading to muscles of the hand, forearm, and arm. The affected person usually remains conscious during the attack.
In this form, originally identified by English neurologist Hughlings Jackson, the patient often remains conscious but experiences muscle twitching. These episodes are triggered by an irritant affecting the brain’s surface. Surgical removal of this irritant can frequently lead to a complete cure.
A type of epilepsy where seizures affect only specific muscles, resulting from particular damaged regions in the brain.
