What is temporal lobe epilepsy

An EEG records what is temporal lobe epilepsy electrical activity of the brain via electrodes affixed to the scalp. EEG results show changes in brain activity that may be useful in diagnosing brain conditions, especially epilepsy and other conditions that cause seizures. During a high-density EEG test, electrodes are placed on your scalp closely spaced together.

Epilepsy is a brain disorder that causes changes in brain cell activity that result in seizures, periods of unusual behavior or feelings, and in some cases a loss of consciousness. Temporal lobe epilepsy is one of 20 different kinds of epilepsy. There are two types of temporal lobe epilepsy. Each is defined by the part of the temporal lobe in which it originates. One starts in the medial inner region of the temporal lobe, while the other starts in the neocortical side region of the temporal lobe.

Usually a person has had a seizure with fever or an injury to the brain in their early years. 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. Mesial temporal lobe epilepsy is often associated with changes or abnormal findings on MRI magnetic resonance imaging. One of the most common findings is scarring in the temporal lobe. This is called hippocampal sclerosis sclerosis means hardening or scarring. It may look like the hippocampus on one side, or both, has shrunk or is smaller. When the MRI is abnormal, seizures often do not stop with medication. In this case, surgery to remove the area causing the seizures is the best option for many people. Seizures in TLE include focal aware seizures , such as auras , and focal impaired awareness seizures.

Seizures and epilepsy. Occasionally, patients may manifest with a change in the prosody of speech and flattening of the contralateral nasolabial fold with emotional incitement. It also permits for evaluation of patients who are not close to epilepsy centers.

Kids with temporal lobe epilepsy have seizures that start in one of the temporal lobes of the brain. The temporal lobes are on the sides of the brain, behind the temples. This area is involved in controlling emotions, memory, and language. The seizures in temporal lobe epilepsy are focal seizures. Focal seizures begin in one area of the brain, and may or may not spread to other areas of the brain. Someone having a focal onset impaired awareness seizure may stare, rub their hands, or smack their lips. It may be hard to speak or understand language during the seizure.

An EEG records the electrical activity of the brain via electrodes affixed to the scalp. EEG results show changes in brain activity that may be useful in diagnosing brain conditions, especially epilepsy and other conditions that cause seizures. During a high-density EEG test, electrodes are placed on your scalp closely spaced together. A high-density EEG test can help your health care provider locate the area in your brain where seizures occur. A CT scan can see nearly all parts of the body and is used to diagnose disease or injury as well as to plan medical, surgical or radiation treatment. These SPECT images show the blood flow in the brain of a person when there's no seizure activity left and during a seizure middle.

What is temporal lobe epilepsy

In the field of neurology, temporal lobe epilepsy is an enduring brain disorder that causes unprovoked seizures from the temporal lobe. Temporal lobe epilepsy is the most common type of focal onset epilepsy among adults. Diagnosis relies on electroencephalographic EEG and neuroimaging studies. Under the International League Against Epilepsy ILAE classification of the epilepsies , focal onset epilepsy occurs from seizures arising from a biological neural network within a single cerebral hemisphere. During a temporal lobe seizure, a person may experience a seizure aura ; an aura is an autonomic, cognitive, emotional or sensory experience that commonly occurs during the beginning part of a seizure. The common auras from seizures arising from primary auditory cortex include vertigo , humming sound, ringing sound, buzzing sound, hearing a song, hearing voices or altered hearing sensation. The major cognitive impairment in mesial temporal lobe epilepsy is a progressive memory impairment. Psychiatric disorders are more common among those with epilepsy, and the highest prevalence occurs among those with temporal lobe epilepsy. Geschwind syndrome is a syndrome of altered sexuality most often hyposexuality , religiosity , and compulsive or extensive writing and drawing occurring in persons with temporal lobe epilepsy. Hippocampal sclerosis , brain tumor , traumatic brain injury , cerebral vascular malformation , neuronal migration disorders , infections such as encephalitis and meningitis , autoimmune disease limbic encephalitis and genetic disorders may cause temporal lobe epilepsy.
