EEG clinical application

Epilepsy

Because the EEG can accurately record scattered slow waves, spikes, or irregular spikes during epileptic seizures, the EEG test is very accurate for diagnosing epilepsy, and the EEG anti-epileptic drug has guidance for stopping the drug. effect.

2. mental illness

In order to confirm the diagnosis of schizophrenia, manic depression, mental abnormalities, etc., EEG examination can be done to exclude other diseases of the brain including epilepsy.

3. Other diseases

The brain activity graphics recorded by EEG can not only explain the limited or diffuse pathological manifestations of brain diseases such as epilepsy, tumors, trauma and degenerative diseases, etc., but also for extra brain diseases such as metabolic and endocrine disorders and Changes in the central nervous system caused by poisoning, etc. are also of diagnostic value.

EEG examination is an effective method for examining changes in brain function. Because changes in brain function are dynamic and changeable, some patients with clinical manifestations of brain dysfunction did not have an EEG examination. When abnormalities are found, the existence of brain diseases cannot be completely ruled out, but regular EEG reviews should be performed to accurately detect the diseases.
