Some of the signs and symptoms of a seizure include loss of consciousness, convulsions, muscle rigidity, blurred vision and loss of muscle tone. Others include memory lapse, unusual smells, losing control of urine or stool, repeated blinking of eyes, and a feeling of panic or impending danger, according to the Epilepsy Foundation.
As a seizure develops, some patients experience convulsions or jerking movements, explains the Epilepsy Foundation. The sudden stiffening of the muscles is caused by tonic seizures, which may make the patient collapse. Muscle contraction causes jerking of the body, clamping of the jaws and biting of the tongue.
During complex focal seizures, a person may seem to be in a dream-like state and may involuntarily chew, walk or perform repetitive, unorganized and confused actions. A patient may stare into space or have subtle body movements such as eye blinking or lip smacking. Sometimes the patient drools uncontrollably, states the Epilepsy Foundation.
Some patients are unable to speak or move until the seizure is over. Uncontrolled movements can occur throughout the body, and a person may experience emotions such as fear, joy, rage and odd sensations such as ringing sounds or strange smells. It causes confusion, anxiety and difficulty in completing simple tasks such as writing and holding objects.
