Answer: D. Seizure.
A seizure is a sudden and temporary alteration in brain function that is caused by massive continuing electrical discharges n a group of nerve cells in the brain. The abnormal electrical discharge typically produces changes in mental activity and behaviour ranging from brief trancelike periods of inattention to unresponsiveness and the jerky muscle contractions that are known as convulsions. A seizure is not a disease but rather a sign of an underlying defect, injury or disease. A common cause of seizures is epilepsy, a chronic brain disorder that is characterized by recurrent seizures.
