- Generalized seizures:
All areas of the brain (the cortex) are involved in a generalized seizure.
Sometimes these are referred to as grand mal seizures. - To the observer, the
person experiencing such a seizure may cry out or make some sound,
stiffen for some seconds, then have rhythmic movements of the arms and
legs. Often the rhythmic movements slow before stopping. - Eyes are generally
open. - The person may not
appear to be breathing. The person is often breathing deeply after an
episode. - The return to consciousness
is gradual and should occur within a few moments. - Loss of urine is
common. - Often people will be
confused briefly after a generalized seizure.
- Partial or focal seizures:
Only part of the brain is involved, so only part of the body is affected.
Depending on the part of the brain having abnormal electrical activity,
symptoms may vary. - If the part of the
brain controlling movement of the hand is involved, for example, then
perhaps only the hand may show rhythmic movements or jerking. - If other areas of the
brain are involved, symptoms might include strange sensations or small
repetitive movements such as picking at clothes or lip smacking. - Sometimes the person
with a partial seizure appears dazed or confused. This may represent a
partial complex seizure. The term complex is used by doctors to
describe a person who is between being fully alert and unconscious.
- Absence or petit mal
seizures: These are most common in childhood. - Impairment of
consciousness is present with the person often staring blankly. - Repetitive blinking or
other small movements may be present. - Typically, these
seizures are brief, lasting only seconds. Some people may have many of
these in a day. - Other seizure types
exist, particularly in very small children.
