Partial seizures are also well-known under the two other names: focal seizures and localized seizures. 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 who suffer from epilepsy most frequently face this type of seizures. If simple partial seizure leads to complex partial seizure than the simple partial seizure is called aura, and complex partial seizure is called tonic-clonic seizure.
When it comes to the simple partial seizure, the person stays conscious, but movements, emotions and sensations are affected. He or she has sudden feelings 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 the seizure stops. Complex partial seizure is commonly known as psychomotor epilepsy. When this kind of seizure happens, the person loses consciousness and becomes unaware, as a sleepwalker. The person stays active performing some actions, for example, undressing, and wanders around, but is unable to interact with other people and has amnesia or cannot remember what was happening during the seizure when she or he returns to the normal state. Partial seizures must 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 usual treatment involves medication, surgery or electrical brain stimulation. Medications can only 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 physician prescribed them, and without exception. Of all the medications, many anti epilepsy drugs and anticonvulsants are used for treating partial seizures but there is no a specific one which, is the most effective. Anticonvulsants can prevent return of the seizure. The most common anticonvulsants are Crabamazepine, Divalproex sodium, Gabapentin, Lamotrigine, Phenobarbital, Phenytoin,Fosphentyoin, Primidone, Fiagabine, Topiramate, and Oxcarbazepine.
If the medications are not much helpful then the surgery is recommended. It includes the 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 colostomy. If from some 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 in the chest wall in order to electrically stimulate the brain by little burst of energy.
