Temporal lobe epilepsy characteristics of the Attack

Temporal lobe epilepsy is characterized by simple partial seizure, and the onset is usually part of secondary systemic attack or mixed these attacks, a common history and family history of febrile seizures, memory defect may occur. In metabolic imaging studies (such as PET), often observed that the low regional metabolism, often in the EEG showed unilateral or bilateral temporal lobe spikes. The diagnosis suggested that the general features are: ① simply part of the attack is a typical feature of the autonomic and (or) some of the spirit and feeling symptoms (such as olfactory and auditory) phenomena (including illusion,), the most common is abdominal (mostly rising) feeling. ② complex partial seizures often stop to campaign began, and then typically arise mouth? Silkworm? Automatic disease, often in the ensuing other automated. The duration of seizures in one minute more, it frequently was confusion after the attack, after the attack forgotten. Seizures can be intermittent period scalp EEG normal background activity can be expressed as mild or significant asymmetry, but also manifested as unilateral or bilateral, synchronous or asynchronous the temporal lobe spikes, a sharp wave and (or) slow wave. Hippocampus attack is the most common form of attack and the characteristics of the rise of upper abdominal discomfort, nausea, autonomic symptoms and signs, such as, navel and looking pale, facial Expanding redness, breathing stopped, expanding pupil , fear, terror and olfactory hallucinations. Simple lateral temporal lobe seizures to listen to the characteristics of illusion or hallucination or sleeping state, as well as visual barriers to know sexy. If involved advantage hemisphere, a language barrier, if the medial temporal lobe involvement or temporal lobe, or complex partial seizures for evolution.
