Temporal lobe epilepsy memory

Some symptoms of a temporal lobe seizure may be related to these functions, including having odd feelings — such as euphoria, deja vu or fear. Abnormalities in the temporal or frontal lobes of the brain are the most common reason for memory problems in people with epilepsy. The left temporal lobe is important for verbal memories such as learning names and remembering facts for exams.

If you have seizures that start in this area you may have problems remembering words, and get stuck mid-sentence. The right temporal lobe is important for visual memories like remembering a person’s face or finding your way around a place. Temporal lobe epilepsy ( TLE ) is the most common form of focal (partial) epilepsy.

It can be hard for people with TLE to become completely seizure free with seizure medicines alone, though medicines may lower the number of seizures. Despite years of research into the causes of epilepsy and the treatment of seizures, little attention has been paid to the causes of memory loss and depression in patients with temporal lobe epilepsy ( TLE ), the commonest drug resistant form of epilepsy in adults. Patients with TLE often show progressing memory loss over a period of years. The temporal lobe is responsible for the emotion process and the short-term memory.

These early feeling does not necessarily occur in all the patient suffering from temporal lobe epilepsy. So if your epilepsy is caused by a tumour or lesion in the temporal lobe , this can also cause memory problems. Some epilepsy medicines may affect your memory , because they can slow down the speed at which your brain processes information.

On the other han epilepsy medicines work to reduce the number of seizures you have.

TLE is the most common form of epilepsy with focal seizures. The epilepsy of the temporal lobe is of two types: In the middle inner region of the temporal lobe. SALLIE BAXENDALE: “Until now, verbal and visual memory difficulties have usually been interpreted to indicate bilateral temporal lobe dysfunction and have been seen as a bad prognostic factor, both in terms of postoperative seizure control and cognitive decline. This is a type of partial seizure meaning it occurs on only one hemisphere of the brain.

Simple partial seizures affect a small area of the brain and the person retains awareness. A focal seizure is just a surge of electrical activity in one part of the brain, as opposed to a generalized seizure which affects multiple areas. Mesial temporal lobe epilepsy (MTLE) is the most common epilepsy syndrome with pharmacologically intractable partial-onset seizures. The MTL memory system is essential to declarative memory processes underlying memory for new events and facts 4. Start studying Module - Memory in temporal lobe epilepsy. Learn vocabulary, terms, and more with flashcards, games, and other study tools.

The issue of topographical amnesia, which would seem to involve parts of the brain not usually associated with other TEA symptoms, was referred to earlier. Focal seizures are the most common form of seizure in adults and one of the most common forms of seizures in children. Memory complaints and deficits are common in patients with epilepsy , especially temporal lobe epilepsy (TLE), where memory -related brain structures are directly involved in the epileptic process.

In recent years, substantial progress has been made in delineating memory impairment in TLE, challenging the traditional neuropsychological approach of the disorder. They are involved in recognition and processing of soun language and smells and play a key role in the formation of memory. Its key functions include roles in sound and language processing.

Moreover, it is also used in functions that are related to memory and emotion management.

Studies on amnesia and animal studies have revealed the anatomical components of the memory system, located within the medial temporal lobe. This has been found to include the hippocampus and adjacent, anatomically related cortex, including the entorhinal, perirhinal and parahippocampal cortices. This lobe, which is located above your ears, controls your memory, as well as language and emotions, and it’s one of the most frequent locations in the brain for seizures to occur.

For someone with epilepsy whose seizures arise from the temporal lobe,. Complaints of memory difficulties are common among patients with epilepsy , particularly with temporal lobe epilepsy where memory -related brain structures are directly involved by seizure activity. People with temporal epilepsy caused by hippocampal sclerosis.

However, the reason for these complaints is often unclear and patients frequently perform normally on standard neuropsychological tests of memory.
