• If this activity remains confined to a small area of
  brain, the result is a focal seizure. During this type
  of seizure, a patient remains conscious and may
  experience a strange sensation, such as a smell or
  taste, or have a brief episode of uncharacteristic
  behavior. Another common type of focal seizure
  includes the uncontrolled movement of an arm or
  leg. These seizures usually last from seconds to
  minutes and a complete recovery occurs within the
  same time period.
• A generalized seizure occurs when the electrical
  activity spreads throughout the brain. When this
  occurs, the patient loses consciousness, falls to the
  ground and may have uncontrolled movements of
  the body, arms and legs. Control over the bowel
  and bladder may be lost. The seizure can go on for
  several minutes, then it may take several hours for
  the person to awaken.
