This test is performed to help in the diagnosis of diseases in patients with suspected epilepsy, inflammation of the brain, strokes, dementia's etc. which alter the function of the brain. These are potentials produced by the brain in response to specific stimuli, for example a flashing light, or sounds, such as a click. These can be used for assessing hearing and vision as well as neurological disorders such as multiple sclerosis. These tests look at the way in which nerves and muscles in the body are working and help in the diagnosis of diseases such as muscular dystrophies, nerve dysfunction etc. They can also be carried out in intensive care units.
Some departments provide an on-call service.
The Association organises short courses and one-day seminars, which may lead to further qualification. Frequent scientific meetings are held throughout the country. The Association publishes a monthly newsletter distributed to members only, and a scientific journal three times a year. This is a fast growing area of development, where increasingly, high technology and computerisation is employed, but where technologists still work very closely with patients and the medical profession. Neurophysiology is usually based in hospitals and linked to neurological centres.
