What is qeeg?
Quantitative electroencephalography (QEEG) is a medical diagnostic test that is used to measure electrical brain activity and individual brain function. During the procedure there are 19 sensors on the head, often as part of a device known as Lycra Cap. Each cap on the cap is located in a predetermined position according to scientific standards. Cable connection of this cap on a computer that processes data for analyzing different brains and creates a graphic map of brain activity.
During QEEG, the technicians make sure the patient is comfortable as soon as all the device is connected. The data is recorded while the patient's eyes are open and closed while reading, and trying to solve mathematical problems. The results are compared with standard brain activity patterns for people in the same age group as the test person.
The brain waves are measured according to their frequency belts. Of 19 that are usually rated Qeeg, some of the Thly frequency are delta, theta, alpha, beta1, beta2,Beta3, high beta and gamma. Some patterns of waves indicate a condition of sleep as well as coma, brain infection or epileptic activity. Such measurements of activity that have been studied from the age of 30 can also be used to diagnose attention disorder with hyperactivity (ADHD), but the diagnostic tool does not provide information on the physical structure of the brain.
QEEG's final result is a graphic message that can be anywhere from 12 to 30 pages. This message describes the test process, the patient and the normal and unusual results that appear. Electric measurements from all 19 regions are detailed and compared to each other. The QEEG brain map is created and organizes wave -shaped data into a topographic perspective, which includes colors to display the amplitude of electrical activity detected from the brain area difference.
Qeeg does not include any invasive patient procedures, nor does it cause pain. Analysis and mapping tRun for several hours. Using diagnostic data, technicians and doctors can identify various injuries and neurological disorders such as depression, dependence and obsessive compulsive disorder. Part of the affected brain and a change in deductions from normal can help determine what drugs, what doses and which treatment may be necessary.
