Treatment

Epilepsy is usually treated with medication prescribed by a physician; primary caregivers, neurologists, and neurosurgeons all frequently care for people with epilepsy. In some cases the implantation of a stimulator of the vagus nerve, or a special diet can be helpful. Neurosurgical operations for epilepsy can be palliative, reducing the frequency or severity of seizures; or, in some patients, an operation can be curative.

 

Responding to a seizure

In most cases, the proper emergency response to a generalized tonic-clonic epileptic seizure is simply to prevent the patient from self-injury by moving him or her away from sharp edges, placing something soft beneath the head, and carefully rolling the person into the recovery position to avoid asphyxiation. In some cases the person may seem to start snoring loudly following a seizure, before coming to. This merely indicates that the person is beginning to breathe properly and does not mean he or she is suffocating. Should the person regurgitate, the material should be allowed to drip out the side of the person's mouth by itself. If a seizure lasts longer than 5 minutes, or if the seizures begin coming in 'waves' one after the other - then Emergency Medical Services should be contacted immediately. Prolonged seizures may develop into status epilepticus, a dangerous condition requiring hospitalization and emergency treatment.

Objects should never be placed in a person's mouth by anybody - including paramedics - during a seizure as this could result in serious injury to either party. Despite common folklore, it is not possible for a person to swallow their own tongue during a seizure. However, it is possible that the person will bite their own tongue, especially if an object is placed in the mouth.

With other types of seizures such as simple partial seizures and complex partial seizures where the person is not convulsing but may be hallucinating, disoriented, distressed, or unconscious, the person should be reassured, gently guided away from danger, and sometimes it may be necessary to protect the person from self-injury, but physical force should be used only as a last resort as this could distress the person even more. In complex partial seizures where the person is unconscious, attempts to rouse the person should not be made as the seizure must take its full course. After a seizure, the person may pass into a deep sleep or otherwise they will be disoriented and often unaware that they have just had a seizure, as amnesia is common with complex partial seizures. The person should remain observed until they have completely recovered, as with a tonic-clonic seizure.

After a seizure, it is typical for a person to be exhausted and confused. (this is known as post-ictal state). Often the person is not immediately aware that they have just had a seizure. During this time one should stay with the person - reassuring and comforting them - until they appear to act as they normally would. Seldom during seizures do people lose bladder or bowel control. In some instances the person may vomit after coming to. People should not eat or drink until they have returned to their normal level of awareness, and they should not be allowed to wander about unsupervised. Many patients will sleep deeply for a few hours after a seizure - this is common for those having just experienced a more violent type of seizure such as a tonic-clonic. In about 50% of people with epilepsy, headaches may occur after a seizure. These headaches share many features with migraines, and respond to the same medications.

It is helpful if those present at the time of a seizure make note of how long and how severe the seizure was. It is also helpful to note any mannerisms displayed during the seizure. For example, the individual may twist the body to the right or left, may blink, might mumble nonsense words, or might pull at clothing. Any observed behaviors, when relayed to a neurologist, may be of help in diagnosing the type of seizure which occurred.
