Epilepsy is a persistent neurological situation that causes episodes of irregular electrical exercise within the mind, leading to seizures. Temporal lobe epilepsy (TLE) seizures start within the temporal lobe and sometimes contain uncommon emotions, actions, or behaviors.
Throughout a TLE seizure, an individual could stay aware or lose consciousness.
Potential causes of TLE embody febrile seizures and a few sorts of mind harm, however, typically, the causes stay unknown.
It’s often attainable to regulate TLE seizures with therapies corresponding to medicine, surgical procedure, and dietary modifications.
Preserve studying to be taught extra about TLE, together with its causes, signs, and therapy choices.
Of the types of epilepsy, focal epilepsy is the commonest. Focal epilepsy entails seizures that start in a single space of the mind.
TLE is the commonest kind of focal epilepsy. Based on the Epilepsy Basis, TLE happens in round 6 out of 10 individuals with focal epilepsy. TLE seizures start or happen in a single or each temporal lobes, that are concerned in capabilities associated to feelings, recollections, and sensory info.
There are two sorts of TLE, and these relate to the world of the temporal lobe during which seizures happen.
The most typical kind, mesial temporal lobe epilepsy (MTLE), happens within the center or interior space of the temporal lobe. MTLE seizures typically contain the hippocampus or close by areas.
The opposite kind, neocortical TLE, originates within the aspect or outer area of the temporal lobe.
There are a number of potential causes of TLE, although typically the trigger is unknown. More often than not, TLE begins when an individual is aged 10–20 years, however it could happen at any age.
Some attainable causes of TLE embody:
- febrile seizures
- mind harm at a younger age
- head trauma
- mind infections, together with encephalitis or meningitis
- structural modifications within the temporal lobe, together with the hippocampus
The signs of TLE seizures relate to an individual’s consciousness throughout a seizure. These classifications embody focal onset conscious seizures and focal impaired consciousness seizures.
Focal onset conscious seizures
Throughout a focal onset aware seizure, an individual stays alert. These kinds of seizures typically embody unusual emotions or sensations generally known as auras. Nonetheless, auras don’t happen in all individuals who have TLE, and in those that do have them, not everybody remembers them.
Epilepsy auras are the earliest signs of a seizure, and so they could point out an oncoming seizure. Frequent auras embody unusual emotions corresponding to concern, pleasure, or anxiousness.
They might additionally contain uncommon odors, tastes, or sounds. Auras could contain digestive discomfort, nausea, or the sensation of butterflies within the abdomen. Folks may expertise auras that trigger a sense of deja vu or a sensation that begins within the abdomen and rises to the chest or throat.

If an individual loses consciousness throughout a seizure, it is called a focal impaired consciousness seizure. They might repeatedly swallow, chew, or smack their lips. They might additionally stare at or fumble with their fingers.
Through the seizure, the individual might also have problem talking or understanding language. They might even be unable to answer individuals or be unaware of their environment, even when they look like conscious.
After a temporal lobe seizure, an individual could expertise confusion and speech difficulties or really feel extraordinarily weak or sleepy. They might even be unable to recollect the seizure.
A neurologist can use a number of checks to supply a medical prognosis of TLE.
For instance, they will carry out an MRI scan to see if there are structural modifications within the temporal lobe, which might be current with TLE. Often, nonetheless, there isn’t any seen structural drawback with one of these epilepsy.
They might additionally use an EEG test. These present mind waves and electrical exercise when an individual is awake or asleep. If an individual has MTLE, it could be troublesome to diagnose until the EEG data a seizure.
An individual might also be capable to present detailed descriptions of their seizures. A witness may share what they noticed throughout the seizure.
TLE therapy entails taking steps to stop or restrict seizures. To be able to decide one of the best therapy plan, an individual can go to an epileptologist, which is a neurologist specializing in epilepsy. They’ll seemingly counsel choices together with medicines, surgical procedure, and gadgets.
Many individuals use antiseizure medicines to regulate their seizures. Epilepsy surgery is an choice for individuals whose situation doesn’t enhance with medicines. Present process surgical procedure to take away a lesion that’s inflicting seizures could cease or scale back seizures, particularly if the individual has the process as quickly as attainable.
If medicines and surgical procedure will not be efficient, some individuals who have epilepsy could use a vagus nerve stimulation or responsive neurostimulation machine.
Following sure diets — such because the modified Atkins weight-reduction plan, ketogenic weight-reduction plan, or low glycemic weight-reduction plan — might also assist some individuals with epilepsy. Nonetheless, individuals ought to talk about these choices with a physician first and never use them as a alternative for conventional therapy strategies, however slightly as an accompaniment.
There are a number of threat components related to TLE.
A childhood febrile seizure is the
Some widespread threat components for TLE embody:
- infections, together with encephalitis or meningitis, at a younger age
- mind harm
- harm throughout start
- structural modifications within the temporal lobe, together with mind malformations or tumors
- head trauma involving a lack of consciousness
TLE is a persistent mind situation involving seizures within the temporal lobes of the mind. The reason for a TLE seizure is usually unknown.
Throughout a TLE seizure, an individual could stay alert and expertise auras. Alternatively, they might lose consciousness and the power to know language.
It’s attainable to make use of medicine, surgical procedure, and gadgets to regulate TLE. Many individuals efficiently scale back or remove seizures.
