EEG :
EEG (Electroencephalogram) is medical device specialized in analyzing the brain electrical activity, which helps in evaluating neurological problems like seizures, sleep disorders, head injuries, stroke, brain tumors, and other brain problems. It is clinically evaluated by a trained EEG technician who focuses on neural issues besides the preparation for the examination. The patient is being instructed to avoid using any hair treatment with shampoos or chemicals to avoid complications during the test. It is a painless process without any discomfort and on the other hand, lights, flashes, and low levels of blood sugar affect readings of electrical activity of the brain.
