How Is Multiple Sclerosis Diagnosed?
Multiple sclerosis is often difficult to diagnose as symptoms are so varied and can resemble other diseases. It is often diagnosed by a process of exclusion – that is, by ruling out other neurological diseases – so the diagnosis of MS may take months to years. A physician will do a complete history and neurological exam, along with tests to evaluate mental, emotional and language functions, strength, coordination, balance, reflexes, gait, and vision.
Tests to help confirm the diagnosis of MS include:
- Electrophysiological test
- Cerebrospinal fluid exam (spinal tap, lumbar puncture)
- Evoked potential (EP) tests
- Optical coherence tomography (OCT)
- Blood tests
