The symptoms of an epileptic seizure can range from convulsions that involve the entire body to more subtle symptoms such as the victim giving a blank stare for a few moments, according to WebMD. With a partial seizure, the person may make small, repetitive movements or experience odd sensations.
During a grand mal seizure, the person may scream, fall to the ground and begin flailing his arms and legs, states WebMD. During the seizure, his eyes may remain open, and he may appear to stop breathing for a while. He may lose control of his bladder, and his return to consciousness may be gradual and halting. He may be confused for some time. These seizures are also called tonic clonic seizures, according to the Mayo Clinic.
Partial seizures involve only a part of the brain, says WebMD. In addition to repetitive movements, the victim may appear mentally confused. In petit mal seizures, or absence seizures, the person might simply stare off into space or rapidly blink his eyes. This type of seizure only lasts for seconds and is most often found in children.
Most people with epilepsy display the same symptoms each time, according to the Mayo Clinic. Epilepsy has no known cause in about half of the sufferers. In other cases, the condition can be blamed on genetics, traumas to the head, prenatal injuries or infectious diseases.
