An epileptic seizure is due to abnormal electrical activity in the brain. It consists of the involuntary contractions of the muscles in the body. Seizures may be caused by a number of reasons. Those may include, head injuries, lack of oxygen reaching the brain, difficult births, damage and subsequent scarring to the brain tissues, CVA (stroke) or a chemical imbalance. Bright flashing lights or certain smells can trigger a seizure.
An Absence Seizure is caused by a minor disturbance in the brains electrical activity. The signs and symptoms of a casualty suffering from Absence Seizures may be so minimal that the condition may go untreated for years.
A Tonic Clonic is a recurring major disturbance of the brains activity causing violent and severe movements and thrashing. The casualty also becomes unconscious whilst having the seizure. Some sufferers of epileptic seizures may have a warning period, suddenly smelling a strange smell, tasting a funny taste, or suffering a funny feeling. These warning signs often give the sufferer time to find a safe area to lie down to have the seizure.
Signs and symptoms of an Absence Seizure may include:
- Staring blankly ahead.
- Suddenly stop talking through a sentence.
- Funny noises
- Slight jerking or twitching of the lips, eyes, limbs or head.
- Odd movements eg: lip smacking, clicking the tongue, chewing the lip.
