A gran mal seizure looks very different from the temporal lobe or petite mal seizure.
Before the Seizure
A typical grand mal seizure starts with a loss of consciousness and falling down. This is followed by a 15- to 20-second period with muscle rigidity (tonic phase) and then a one- to two-minute period of violent, rhythmic convulsions (clonic phase).
During the Seizure
During a grand mal seizure, you may take on a dusky appearance, resulting from decreased blood oxygen levels due to impaired breathing during the seizure. Most grand mal seizures last from 30 seconds to five minutes.
After the Seizure
After the seizure, you may experience a headache and drowsiness or confusion.
Note:
Seizures often occur randomly, though in rare cases, stimulation by light, sound or touch can trigger a seizure in susceptible people. Sleep deprivation and excessive alcohol use also may trigger seizures.
