Tonic clonic seizures
Tonic-clonic seizures, better known as grand mal seizures
, are the most noticeable type of epileptic seizures.
When you have this type, your body stiffens, jerks, and shakes, and you lose consciousness
. Sometimes you lose control of your bladder or bowels.
They usually last 1 to 3 minutes
, but if they go on longer, someone should call 911. These seizures follow a pattern:
- Firstly, you seem to "check out." You won't answer if people talk to you. You won't react if someone waves a hand in your face or shakes you. You may collapse.
- Secondly, your muscles clench and become as stiff as a board. (This is the tonic phase. It lasts a few seconds.)
- Next comes a series of jerking movements. (This is the clonic phase. It can last a few seconds or several minutes.)
- Eventually, the jerking stops and you're alert and can talk again, but you may be dazed or unsteady for a little while.
