Claim: CP is a disorder affecting movement.

An epileptic seizure , also known as an epileptic fit , seizure or fit , is a brief episode of signs or symptoms due to abnormal excessive or synchronous neuronal activity in the brain . The outward effect can vary from uncontrolled jerking movement -LRB- tonic-clonic seizure -RRB- to as subtle as a momentary loss of awareness -LRB- absence seizure -RRB- . Diseases of the brain characterized by an enduring predisposition to generate epileptic seizures are collectively called epilepsy .   Seizures can also occur in people who do not have epilepsy for various reasons including brain trauma , drug use , elevated body temperature , low blood sugar and low levels of oxygen . Additionally , there are a number of conditions that look like epileptic seizures but are not .   A first seizure generally does not require long term treatment with anti-seizure medications unless there is a specific problem on either electroencephalogram or brain imaging .   5 -- 10 % of people who live to 80 years old have at least one epileptic seizure and the chance of experiencing a second seizure is between 40 % and 50 % . About 50 % of patients with an unprovoked apparent `` first seizure '' have had other minor seizures , so their diagnosis is epilepsy . Epilepsy affects about 1 % of the population currently and affected about 4 % of the population at some point in time . Most of those affected -- nearly 80 % -- live in developing countries .
