Partial seizuresare also well-known under the two other names: focal seizures and localizedseizures. They have an effect on only one part of the brain or one brain hemisphere.Partial seizures can be simple partial seizures and complex partial seizures, which can even lead to the extreme cases of generalized seizure.
People whosuffer from epilepsy most frequently face this type of seizures. If simplepartial seizure leads to complex partial seizure than the simple partialseizure is called aura, and complex partial seizure is called tonic-clonicseizure.
When it comes to the simplepartial seizure, the person stays conscious, butmovements, emotions and sensations are affected. He or she has suddenfeelings of fear, anxiety, happiness, nausea, or even the sense of déjà vu may suddenly appear, as well as illusions and hallucinations. The person remembers all when theseizure stops. Complex partial seizure is commonly known as psychomotorepilepsy. When this kind of seizure happens, the person loses consciousness andbecomes unaware, as a sleepwalker. The person stays active performing someactions, for example, undressing, and wanders around, but is unable to interactwith other people and has amnesia or cannot remember what was happening duringthe seizure when she or he returns to the normal state. Partial seizuresmust be treated because they can be life-threatening in some cases, or can leave serious damage and impact on the functioning of many organs.
The usualtreatment involves medication, surgery or electrical brain stimulation. Medications canonly prevent or control possible seizures in people who suffer from epilepsy, but cannot cure epilepsy. The medications must be used every day exactly the way that the physicianprescribed them, and without exception. Of all the medications,many antiepilepsy drugs and anticonvulsants are used for treating partialseizures but there is no a specific one which, is the most effective. Anticonvulsantscan prevent return of the seizure. The most common anticonvulsants are Crabamazepine,Divalproex sodium, Gabapentin, Lamotrigine, Phenobarbital, Phenytoin,Fosphentyoin, Primidone, Fiagabine, Topiramate, and Oxcarbazepine.
If themedications are not much helpful then the surgery is recommended. It includesthe removal of the region of the brain where these seizures happen. If the removal cannot be done, then in that case disconnection of the nerve cells is being done. This kind of operation is done to prevent drop attacks and it is called corpus callosotomy. If fromsome reason, the surgery cannot be performed, then vagus nerve stimulation (VNS) is suggested.Vagus nerve is in the neck. For VNS treatment, small battery must be placed inthe chest wall in order to electrically stimulate the brain by little burst ofenergy.
