According to WebMD, the signs of a seizure vary depending on seizure type; however, some signs of a grand mal seizure are loss of consciousness, collapse, a stiff body for 30 to 60 seconds, violent convulsions and a deep sleep. There may also be tongue biting and urinary function accidents. With an absence seizure, the person abruptly ceases an activity and stares briefly. This can happen several times a day.
WebMD explains that myoclonic seizures are characterized by occasional and sometimes violent jerks, often on both sides of the body. Violent jerking may also involve dropping or throwing items. With clonic seizures, symptoms are rhythmic, repetitive jerks of both sides of the body. Muscle stiffening is a major symptom of tonic seizures, while an abrupt loss of muscle tone is a major symptom of an atonic seziure. This loss of muscle tone frequently occurs in the arms and legs and leads to falling.
WebMD says that symptoms of partial seizures can include muscle rigidity; spasms; unusual hearing, smell, touch and taste sensations; and automatic behaviors to do with chewing, walking and lip smacking. Mayo Clinic explains that partial seizures are also called focal seizures, and the other types of seizures are called generalized seizures.
