Multiple Sclerosis (MS) is an autoimmune system disorder that affects the central nervous system. In MS, the immune system attacks the protective myelin sheath covering nerve fibers leading to disruption of conduction of nerve signals. This leads to interference in communication between the brain and the rest of the body.

Symptoms of Multiple Sclerosis include:

• Loss of Vision or double vision
• Clumsiness or a lack of coordination
• Instability
• Slurring of speech Numbness
• Tingling sensation
• Difficulty in concentrating
• Weakness in limbs

No single test can confirm a diagnosis, so a doctor will use several strategies when deciding whether a person meets the criteria for a diagnosis.

Investigations recommended for evaluation include

MRI – MRI scans of the brain and spinal cord, which may reveal lesions.

Spinal tap – Spinal fluid analysis, which may identify antibodies that suggest a previous infection.

Evoked potential tests – An evoked potential test, which measures electrical activity in response to stimuli.

Blood tests – Doctors use blood tests to eliminate other conditions with similar symptoms.
