In this case, surgery to remove the area causing the seizures is the best option for many people. When the MRI is abnormal, seizures often do not stop with medication. Right Mesial Temporal Sclerosis (MTS) with FlairĪlso, see arrow in figure at the top of the page. It may look like the hippocampus on one side, or both, has shrunk or is smaller. This is called hippocampal sclerosis (sclerosis means hardening or scarring). One of the most common findings is scarring in the temporal lobe. Mesial temporal lobe epilepsy is often associated with changes or abnormal findings on MRI (magnetic resonance imaging). There are a lot of older names for seizures that occur in TLE, including "psychomotor seizures," "limbic seizures," "temporal lobe seizures," "complex partial," and "simple partial." The modern name for these seizures is "focal onset seizures." Focal seizures are then described by whether a person stays awake and aware or has impaired awareness during a seizure. Usually a person has had a seizure with fever or an injury to the brain in their early years. Medial temporal lobe epilepsy usually begins around age 10 or 20, but it can start at any age.
It’s called jamais vu, which is French for “never seen.” Jamais vu involves the same brain regions, but is felt as the opposite of déjà vu.
Our ‘rational’ brain tries to make sense of these discordant inputs, which leaves us feeling familiar and unfamiliar all at once.”Ī less common but equally strange sensation is also associated with TLE. “A seizure in this brain region sets off a sensation of familiarity and emotions uncoupled from the real environment. “Although there is still debate over specifics, the prevailing explanation for déjà vu goes something like this,” says Fisher. Adjacent to the hippocampus is the amygdala, which is involved in regulating emotion. The seahorse-shaped part of the brain is involved with the process of memory. Robert Fisher, an epileptologist at Stanford University. “It also plays a role in déjà vu,” says Dr.
The hippocampus is the part of the brain where medial TLE seizures often originate. Today, though, science has far more persuasive explanations for déjà vu. The recounting of such experiences has been documented in literature for centuries. About two-thirds of all people have experienced it. The phrase déjà vu means “already seen” in French. “Sometimes, however, the déjà vu isn’t an aura-it is the seizure itself,” Dr. “That means it’s a feeling that can precede seizures that may go on to eclipse consciousness or even generalize into tonic-clonic seizures.” Paul Garcia, an epileptologist at the University of California, San Francisco. “On one hand, déjà vu is a common aura,” says Dr. Temporal lobe epilepsy (TLE) is the most frequently seen partial seizure disorder in adults, and it can often be accompanied by a feeling of déjà vu. Ever had the feeling that you’ve experienced a certain moment before? It’s called déjà vu, and although most occurrences are likely not related to epilepsy, the feeling can reflect seizure activity in the brain and is prevalent among people with epilepsy.
