But some kinds of brain wave patterns associated with seizures do tend to run in families. Generalized seizures begin with a discharge of neurons throughout the brain . Cause loss of consciousness and stiffening of body, followed by violent jerking of limbs and irregular breathing. Usually last 1 to 2 minutes. Most common in children ages 6 to 14.
Attacks last only a few seconds.
Partial seizures begin with a discharge of neurons in just one part of the brain. May be limited to uncontrolled body movements. May involve brief changes in how things look, sound, taste or feel. Do not usually affect consciousness. Confusion after a seizure may be prolonged.
