What is temporal mesial sclerosis?
Mesial temporal sclerosis (MTS) is a term used to describe scarring in the deep part of the temporal lobe of the brain. MTS is the most common cause of structural epilepsy and focal seizures in the temporal lobe.
Is temporal lobe epilepsy a disability?
Adults with epilepsy may be eligible for Social Security disability benefits. The Social Security Administration (SSA) evaluates epilepsy according to the type, frequency, duration, and nature of the seizures.
How is mesial temporal sclerosis diagnosed?
The changes associated with mesial temporal sclerosis are usually identifiable on a magnetic resonance imaging (MRI) scan. This scan uses magnets, radio waves, and a computer to form pictures of the body’s structures.
Can you drive if you have temporal lobe epilepsy?
To drive, you must meet all normal driving requirements and must have been completely free of seizures for one year, with or without taking anti-epileptic drugs (AEDs). Different regulations may apply if your seizures do not affect your consciousness (see below).
When does mesial temporal sclerosis cause epilepsy?
Mesial temporal sclerosis may happen when the brain doesn’t get enough oxygen or if you have experienced head trauma or an infection in the brain infection. However, the cause of mesial temporal sclerosis is sometimes unknown. Mesial temporal sclerosis can cause a type of epilepsy called temporal lobe epilepsy.
Do you need a MRI for mesial temporal sclerosis?
Furthermore, in adults 3-10% of cases of mesial temporal sclerosis demonstrate bilateral changes 5 even though symptoms may be unilateral. MRI is the modality of choice to evaluate the hippocampus, however dedicated TLE protocol needs to be performed if good sensitivity and specificity is to be achieved 5.
What causes scarring in the temporal lobe of the brain?
Mesial temporal sclerosis is scarring in the inner portions of the temporal lobe, which is the part of the brain that process emotions and is important for short-term memory. Mesial temporal sclerosis may happen when the brain doesn’t get enough oxygen or if you have experienced head trauma or an infection in the brain infection.
When does perfusion increase in the mesial temporal lobe?
During the peri-ictal phases, perfusion is increased, not only in the mesial temporal lobe but often in large parts of temporal lobe and hemisphere. In interictal periods, conversely, perfusion is reduced 5.
