Diagnosis tests & processes

Neurological conditions can be complicated to diagnose. One or more tests may be required to confirm, or rule out, a diagnosis. If your GP or other healthcare professional recommends you be tested for a neurological condition, they will likely refer you to a neurologist; a medical doctor who specialises in diseases of the nervous system.

Your specialist will do a thorough physical exam and document your medical history. Further tests may then be ordered, and these may include the following.

Diagnostic Tests

What is an arteriogram or angiogram?

This is an x-ray of arteries and veins, often used to diagnose stroke. This test aims to find blockages or narrowing of the vessels.


What is a CAT scan?

CAT stands for ‘computed tomography’ and involves X-rays and computer technology to provide detailed images of the body. It is used to diagnose a range of neurological conditions.


What is an electrodiagnostic test?

Electrodiagnostic tests involve the use of electrodes to test electrical activity and response in muscle groups.


What is an electroencephalogram?

An electroencephalogram, also known as an EEG, is a test that looks at the electrical activity of the brain.


What are evoked potentials?

Evoked potentials, also known as evoked responses, are tests that record the electrical response in the brain to stimuli.


What is an MRI?

Magnetic resonance imaging (MRI) is a technology that uses large magnets, radio frequencies and a computer to create detailed images of the organs and anatomy.


What is a myelogram?

A myelogram is a procedure where a dye is injected into the spinal canal to make its structure visible on x-rays.


What is a neurosonography?

A neurosonography is a test that uses high-frequency sound waves to allow for analysis of blood flow and is used in cases where stroke is suspected.


What is a spinal tap or lumbar puncture?

A spinal tap, also known as a lumbar puncture, is a test where a small sample of cerebral fluid is drawn from the lower spine to test for infection or other abnormalities.


What is an ultrasound?

An ultrasound, also called sonography, is a technique that uses high-frequency sound waves to make images of internal organs and assess the blood flow through the body’s vessels.
