A seizure is a sudden discharge of electrical activity in the brain that may cause a change in behavior, awareness, or sensation.
Abnormal electrical discharges in nerve cells in the brain.
Convulsion; fit; attack of violent muscle contractions.
While there are over 40 types of seizure, most are classed as either partial seizures which occur when the excessive electrical activity in the brain is limited to one area or generalized seizures which occur when the excessive electrical activity in the brain encompasses the entire organ. Although there is a wide range of signs, they mainly include such things as falling to the ground; muscle stiffening; jerking and twitching; loss of consciousness; an empty stare; rapid chewing/blinking/breathing. Usually lasting from between a couple of seconds and several minutes, recovery may be immediate or take up to several days.
uncontrolled electrical activity in the brain that can lead to abnormal muscle movements, changes in behavior, or loss of consciousness.
A seizure is a sudden attack of epileptic convulsion. It is a result of involuntary electrical activity in the brain. It can be associated with uncontrolled motor (movement) or sensory system action. Accordingly, a patient suffering a seizure may experience uncontrollable body movements, unusual smells or tastes and have loss of consciousness (awareness of surroundings).
Involuntary movement or changes in consciousness or behavior brought on by abnormal bursts of electrical activity in the brain.
Seizures are temporary abnormal electro-physiologic phenomena of the brain, resulting in abnormal synchronization of electrical neuronal activity. They can manifest as an alteration in mental state, tonic or clonic movements, convulsions, and various other psychic symptoms (such as déjà vu or jamais vu). They are due to temporary abnormal electrical activity of a group of brain cells.
