Our clinical neurophysiology department performs tests which record information from the brain or the nervous system. There are two main tests performed in our outpatient department:
- Electroencephalogram (EEG)
- Nerve conduction studies (NCS)
Electroencephalogram (EEG) small discs are placed on the scalp with a soluble paste, and the activity of the brain is recorded for about 20 minutes. Most of the test will be performed while the patient reclines comfortably in a chair with the eyes closed. Some deep breathing (hyperventilation) or looking at a flashing light (photic stimulation) may also be required. The test takes approximately one hour overall to perform. Nerve conduction studies (NCS) examine how well peripheral nerves and muscles work. Generally, we look at the nerves in the arms and legs. The test is performed by positioning small discs on the hands, arms or legs. These are used to give small electrical pulses which activate the nerves and are felt as a tapping. The tests are slightly uncomfortable but not painful, and usually last about 20 to 30 minutes in total. They are usually well accepted by children.
We perform tests which record information from the brain or the nervous system for conditions such as epilepsy, carpal tunnel etc.
Routine waits are two to three weeks. Urgent cases will be seen within one week.
