Generalized tonic-clonic seizure
A seizure is a short burst of uncontrolled electrical activity in the brain. A generalized tonic-clonic seizure affects both halves of the brain, and comes in two phases (tonic and clonic). The tonic phase is characterized by rigidity of all muscles and loss of consciousness. Saliva may escape the mouth, and the bladder may contract, releasing urine. The clonic phase follows, when the body appears to shake. This may last from seconds to minutes. The person gradually regains consciousness. A seizure may be caused by an underlying disease such as epilepsy, or by triggers such as heavy drinking, drugs, or anxiety.

My grandfather got tired and sat down. We thought he was taking a nap. He had sunglasses and a hat on so we couldn’t tell he was unconscious until he didn’t respond when we checked his eyes. They had rolled back and we thought he was having a stroke. Then he woke up and was slurring his words and threw up twice. The paramedics came and said it was most likely because of low blood sugar or something to do with his triple bypass surgery that he had 6 months ago.
