Early diagnosis is important since treatment can slow down the progress of the disease. It is a challenge for doctors to diagnose multiple sclerosis. No single test is confirmatory of this condition and it must be deferentially diagnosed from other medical conditions.
Investigations recommended for evaluation include:
1. MRI
Widespread use of MRI (magnetic resonance imaging) has revolutionized the ability to diagnose multiple sclerosis. The characteristic plaques of MS will confirm the diagnosis. The location of the plagues will determine the symptoms.
2. Spinal Tap
The results of a spinal tap test can prove to be very helpful in enabling the doctors to see whether the patient’s body’s immune system is attacking itself. Antibodies associated with MS may be identified.
3. Evoked Potential Tests
These tests map electrical activity in portions of the brain, which evaluates nerve signal transmission.
4. VNG
Findings like the ocular flutter spontaneous nystagmus, hyperventilation-induced nystagmus or direction-changing nystagmus can assist in the diagnosis of multiple sclerosis. (read more)
