What would an abnormal EEG mean?
Abnormal results on an EEG test may be due to: Abnormal bleeding (hemorrhage) An abnormal structure in the brain (such as a brain tumor) Tissue death due to a blockage in blood flow (cerebral infarction) Drug or alcohol abuse.
Can anxiety cause abnormal EEG?
Background. Since the 1980s, a high EEG abnormality rate has been reported for patients with panic disorder.
What is the left temporal lobe responsible for?
The temporal lobes are also believed to play an important role in processing affect/emotions, language, and certain aspects of visual perception. The dominant temporal lobe, which is the left side in most people, is involved in understanding language and learning and remembering verbal information.
Is temporal lobe epilepsy a disability?
Even when on medication people with epilepsy can experience seizures that leave the worn out and unable to function for days. If you have been diagnosed with epilepsy and you can’t work and you expect to be unable to work for at least 12 months you can file a claim for Social Security disability benefits.
Can an EEG detect dementia?
Therefore, temporospatial analysis of the EEG record is a useful indicator of cortical dysfunction in dementia and correlates with the degree of cognitive impairment. Apparently, temporospatial analysis may be useful in distinguishing patients with dementia from those experiencing normal aging.
Are there EEG abnormalities in the temporal lobe?
As a general rule, EEG abnormality may be enhanced in sleep deprivation states and in sleep. EEG abnormalities (spike-and-wave or sharp slow waves) are seen in an anterior temporal distribution in mesial temporal lobe structural brain abnormality.
How are seizures characterized in the temporal lobe?
EEG abnormalities may be seen in a mid-temporal or posterior temporal distribution in lateral temporal lobe structural brain abnormalities. Seizures in mesial temporal lobe structural brain abnormality are characterized by rhythmic theta (or less commonly spike) activity in the anterior temporal EEG leads (F7, T3; F8, T4).
What are the two types of abnormal EEG?
The Abnormal EEG Focal and Generalized Slowing and Significance EEG can provide evidence for underlying diffuse or focal cerebral dysfunction through demonstration of background slowing. The two main types of slowing are focal and generalized slowing.
What does generalized background slowing in EEG mean?
Generalized background slowing indicates diffuse cerebral dysfunction, which, similar to focal slowing, is also not specific as to cause.
