How is Multiple Sclerosis Scientifically Diagnosed?
Diagnosing Multiple Sclerosis does not depend on a single test or one scan alone. Instead, it relies on a precise scientific process known as “diagnosis by exclusion.
• Presence of lesions in different areas of the nervous system
• Occurrence of these lesions at different points in time
1. Magnetic Resonance Imaging (MRI) – Detecting Inflammation
MRI is considered the most accurate method for imaging the brain and spinal cord, as it reveals areas where the myelin sheath surrounding the nerves has been damaged.
2. Neurological Clinical Examination – Assessing Nervous System Functions
The neurologist examines muscle strength, balance, sensation, and reflexes to identify the location of nerve damage.
3. Cerebrospinal Fluid (CSF) Analysis – The Immune Fingerprint
The fluid surrounding the brain and spinal cord is analyzed to detect proteins called Oligoclonal Bands, which may indicate abnormal immune activity.
4. Visual Evoked Potential (VEP) Test
This test measures the speed of nerve signals traveling from the eyes to the brain and may detect silent damage in the optic nerve.
Important Step: Rule Out Other Conditions
Blood tests are performed to rule out other conditions with similar symptoms such as:
- • Vitamin B12 Deficiency
- • Lupus
- • NMOSD
