#WHAT IS AN EEG TEST USED TO DIAGNOSE SERIES#

The main use of an EEG is to detect andВ investigate epilepsy, a condition that causes repeated seizures. It may helpВ identify the cause of certain symptoms вЂ“ such as seizures (fits) or memory problemsВ вЂ“ or find out more about a condition you've already been diagnosed with. When an EEG is usedДЄn EEG can be used to help diagnose and monitor a number of conditions affecting the brain. The EEG procedure is usually carried out by a highly trained specialist, called a clinical neurophysiologist, during a short visit to hospital. These signals are recorded by a machine and are looked at by a doctorВ later to see if they're unusual. If your EEG will be monitored while you are sleeping, you may be asked to reduce the amount of sleep you get the night before.ДЄfter the EEG, you will be allowed to return to your normal daily activities.AnВ electroencephalogram (EEG)В is a recording of brain activity.Дuring the test, small sensors are attached to the scalp to pickВ up the electrical signals produced when brain cells send messages to each other.Wash your hair the day of the test but do not use any oils, sprays, or other hair products.Refrain from eating or drinking any foods that contain caffeine for at least 8 hours before the test.Stop taking certain medications (but only do this if your doctor says itвЂ™s necessary).To prepare for an EEG test, you may be asked to: The test may be stopped to allow you to stretch or re-position yourself for comfort. You will be asked to relax and keep still for the duration of the test, which is usually 30-60 minutes in length.

About 20-25 electrodes, which look like small silver buttons or discs, will be attached to your scalp and then to the EEG machine.

You will be asked to sit or lie down and close your eyes (to keep brain stimulation at a minimum). What can I expect during an EEG?ДЄn EEG test is a painless procedure that is usually performed in your doctorвЂ™s office or in a hospital. If necessary, the patient may be asked to change breathing patterns, look at a bright or flashing light, or even go to sleep to see how the brain functions during these conditions. When a patient is relaxed, EEG waves are slow, and when a patient is excited, the waves move faster. Normal brain activity changes depending on the stimulus. The electrodes only record activity they do not produce any sensations.Дuring an EEG, brain activity is recorded while the patient is at rest. At no time do electrical currents enter the brain.

Electrical impulses that naturally occur throughout the brain are recorded and amplified by the machine and, using a row of pens, are illustrated as a series of wavy lines on a moving piece of paper or on a computer screen. Using a mild adhesive, these electrodes are strategically placed on the scalp and connected to the EEG machine with thin wires.

Brain activity during surgery when a patient is under general anesthesiaД®EG measures brain waves and is able to detect abnormal brain activity through the use of electrodes.

Comatose patients by evaluating or ruling out brain death.

The potential for recovery from cardiac arrest or other major trauma.

Encephalitis (swelling of the brain) and other infections.

Confusion, dementia, and other brain disorders.

What is an EEG used for?Д®EGs are used to help physicians diagnose and treat patients with the following conditions: Through the use of electrodes carefully placed on the scalp, the EEG records the activity of thousands of neurons in the brain. EEG, which stands for electroencephalogram, is a diagnostic test used to detect abnormal brain activity that might indicate a serious medical condition.
