A neuro diagnostic exam is the study of brain activity and the nervous system. A neurodiagnostic tests will be conducted to determine a patient’s illness stemming from any suspected central nervous system (i.e. brain and spinal cord and the peripheral nerves), or in the peripheral nervous system. The results will provide critical information on the functionality of the nervous system.
This examination is essential in other specialties such as orthopaedics, spine surgery, ophthalmologist, general physician, paediatrician, neonatologist and ENT surgeons.
The types of problems commonly referred to a neuro diagnostic lab would include in identifying the following:
Records brain wave function to help diagnose seizures and other related neurological disorders.
Patient is observed through the use of an EEG with simultaneous video monitoring. This is done to document seizure activity over an extended period of time. The patient is admitted to the hospital to monitor his/her safety and events.
Nerve Conduction Velocity (NCV) test is a measurement of the speed of conduction of an Electrical impulse through a nerve.
An EMG measures the electrical activity in muscles and is often performed at the same time as NCS. Both procedures help to detect the presence, location and extent of diseases that damage the nerves and muscles which can cause symptoms of tingling, numbness and pain.
The EP provides a measurement of how long it takes an impulse to travel from a point of stimulation to the brain. Evoked potentials are performed to detect and determine the severity of multiple sclerosis, spinal cord injury or disease and brainstem injury or disease. There three modalities of EPs:
Transcranial Doppler sonography is a noninvasive, non-ionizing and safe technique that uses a pulsed Doppler transducer for assessment of intracerebral blood flow.
A technique that evaluates blood flow in the arteries of the neck that could cause stroke.
