Partial Seizure

Partial Seizure

Partial seizures (also called focal seizures and localized seizures) are seizures which affect only a part of the brain at onset Partial seizures are split into two main categories; simple partial seizures and complex partial seizures. A new classification system for partial seizures has been described in the 18th Edition of Harrison's Principles of Internal Medicine (released July 2011). The new classification splits partial seizures into "partial seizures with dyscognitive features" and "partial seizures without dyscognitive features". In simple partial seizures a small part of one of the lobes may be affected and the person remains conscious. This will often be a precursor to a larger seizure such as a complex partial seizure. When this is the case, the simple partial seizure is usually called an aura. A complex partial seizure affects a larger part of the hemisphere than a simple complex seizure and the person may lose consciousness. If a partial seizure spreads from one hemisphere to the other side of the brain, this will give rise to a secondarily generalised seizure. The person will become unconscious and may well have a tonic clonic seizure.
