This occurs in two phases: the tonic first, followed by the clonic stage. In the tonic stage, the individual becomes stiff as their muscles contract. The muscles in the lungs contract making breathing difficult and often results in the skin turning blue due to a lack of oxygen in the blood. The clonic stage involves jerking movements as the muscles relax and contract in turn. During this phase the individual may bite their tongue and become incontinent. Over time, these contractions become less frequent until they eventually stop. This type of seizure typically lasts less than a minute though it may seem much longer as the episode is so frightening.<\/p>\n<h2>Absence<\/h2>\n<p>This type of seizure typically occurs in children. The child appears to stare blankly and seems to be daydreaming; however, you are temporarily unconscious and are inaccessible.<\/p>\n<h3>Myoclonic<\/h3>\n<p>These seizures may affect the whole body but most typically affect one or both arms and sometimes the head; the seizure causes jerking which can be severe enough to make you fall over.<\/p>\n<h3>Tonic<\/h3>\n<p>The individual becomes stiff as their muscles contract and the individual often falls to the ground. The muscles in the lungs also contract making breathing difficult and can result in skin turning blue due to a lack of oxygen in the blood.<\/p>\n<h3>Atonic<\/h3>\n<p>These are often called &#8220;drop attacks&#8221; and are caused by the sudden but complete loss of muscle tone; this results in an instantaneous collapse to the ground. The individual is usually able to get up straightaway, as the seizure is very brief but you are at high risk of injuring your head as you fall.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Partial Seizures These seizures originate in a particular region rather than across the whole brain.
