A seizure is a change in sensation, awareness or
behavior brought about by a brief electrical disturbance in the
brain. Seizures may be convulsions, short periods of unconsciousness,
distortion of the senses, or loss of control over movement. There
are more than 20 different types of seizures. The kind of seizure
a person has depends on which part of the body is affected by the
electrical disturbance i.e., where in the brain seizure starts and
where it spreads. The most common seizure types are classified as
either partial or generalized.
 |
Generalized Seizures
Generalized seizures happen when the electrical
disturbance sweeps through the whole brain at once, causing
loss of consciousness, falls, convulsions or massive muscle
spasms.
|

|
Partial Seizures
Partial seizures happen when the disturbance
occurs in just one part of the brain, affecting whatever physical
or mental activity that area controls.
