are not all the same. Some can be mild and last only a minute or two. Others can cause problems that last much longer. Sudden, repeating seizures can cause harm to the heart or brain, and death if emergency care is not given right away.
There are many types of seizures. They each have their own symptoms.
Partial or Focal Seizures
These seizures start from one part of the brain. You may have:
Tingling or numbness in the arms, legs, hands, or feet
Muscle twitching on one side of a leg, arm, hand, finger, or muscle
Sensing smells, tastes, sights, sounds, or other things that are not real
Strange, repeating, motions or movements that you cannot control, such as chewing or smacking your lips
Partial seizures may spread from one part of the body to another.
Focal seizures may spread to both sides of the brain.
Generalized Convulsive (Grand Mal) Seizures
These seizures start from both sides of the brain. You may have:
Loss of consciousness
Loss of bladder or bowel control
Muscle spasms or stiffening
A sudden fall to the ground
Strange, repeating motions or movements that you cannot control
Biting your tongue
A sense of a strange warning before it happens, such as the smell of burning rubber.
After it happens, you may have:
Deep sleep, tiredness, confusion, or a change in responsiveness
Problems remembering the seizure
General Seizures Without Convulsions
Absence seizures, also called petit mal, are more common in children. A child may have:
A look of daydreaming
Blinking of the eyes rhythmically
Twitching of the face
No memory of the seizure after it happens
There are also other types of generalized seizures without convulsions.
