Diagnostic Tests for Nervous System Disorders

In this article, you will learn about diagnostic tests for the nervous system disorders. Diagnosis and evaluating your brain is really complicated and complex process.

Many of the symptoms happen to be widely different among the different disorders. To further complicate the diagnostic process, many disorders don’t have definitive tests.

In addition to a complete medical history there would be several diagnostic procedures for the nervous system which may include the following:

Diagnostic Tests for Nervous System Disorders

Computed tomography scan(CT scan) –  A diagnostic imaging process using a combination of X-rays and computer technology to produce both horizontal or axial images of the body.

Computed tomography shows a detailed image of any part of the body, bones, fats, organs etc. CT scans are giving more detailed than any general X-rays.

Magnetic Resonance Imaging (MRI)

This diagnostic procedure using a combination of large magnets, computer, radio-frequencies to giving a detailed image of organs and complete structure within the body.

Electroencephalogram (EEG)

This instrument records the brain continuous electrical activity within the brain. In this electrodes attach to the scalp.

Electrodiagnostic Tests, Such as Electromyography (EMG)

Electromyography also called to be nerve conduction velocity. This test is also evaluated and diagnose disorders of the muscle and motor neuron of the brain function.

In this electrodes are inserted into the muscle or place over the skin or muscle group and recorded the brain response.

Positron Emission Tomography (PET)

This procedure is used to measure the metabolic activity of the cells.

Arteriogram (Also Called an Angiogram)

In this X-ray is send over the arteries and veins where it is used to detect blockage or narrowing of the vessels.

Spinal Tap (Also Called a Lumbar Puncture)

A special needle is to be placed into the lower back of the spinal canal. This area is basically around the spinal cord.

In this pressure in the brain and spinal can be measured.

Then a small amount of cerebrospinal fluid(CSF)  is injected and send for testing to determine there would be no infection or any other problems.

CSF is basically the fluid that bathes the brain and spinal cord.

Help to Evoke Potentials


It also helps to evoke several procedures that record the brain electrical response like visual, auditory and sensory stimuli.


A procedure that uses basically dye which is injected into the spinal canal to make structure visible on X rays.


This procedure basically uses a high-frequency sound wave that helps to analyze the blood flow that may be a cause of stroke in future.

Ultrasound (Also Called Sonography)


This diagnostic imaging uses the high -frequency sound waves and computer to create the complete image of blood vessels, organs, and tissues.

Ultrasound is done to test how internal organs perform several functions and assess blood flow through various vessels.

Well, this was the end of the article on diagnostic tests for nervous system disorders. Proper treatment is necessary to prevent the disease.

Neurointervention (Interventional Neuroradiology) is a medical specialty in which minimally invasive diagnostic and intervention procedures for cerebrovascular disorders are performed under radiological guidance.
