Multiple Sclerosis
✓ VERIFIED AGAINST 38 C.F.R.§ 4.124a (Neurological conditions and convulsive disorders) · reviewed 2026-05-15 · ClaimRecon Editorial Team
Multiple Sclerosis is rated by the U.S. Department of Veterans Affairs under DC 8018 of 38 CFR § 4.124a, DC 8018 across 2 severity tiers (30% / 100%). Service connection requires (1) a current diagnosis, (2) an in-service event, injury, or exposure, and (3) a medical nexus opinion linking the two under 38 C.F.R. § 3.303. This condition is frequently rated as secondary to Major Depressive Disorder or Fatigue under 38 C.F.R. § 3.310.
OVERVIEW
Chronic autoimmune demyelinating disease of the central nervous system causing variable neurological deficits.
RATING CRITERIA (2 LEVELS)
30%
Minimum rating from date of diagnosis per § 4.124a DC 8018.
100%
Per the § 4.124a general framework for organic CNS disease, ratings extend up to 100% based on combined impairment of motor, sensory, or mental function. Each affected residual (motor weakness in extremities, optic neuritis with visual impairment, cerebellar ataxia, bowel/bladder dysfunction, cognitive impairment, depression, fatigue) is rated separately under its applicable DC and combined with the 30% minimum baseline under § 4.25.
KEY EVIDENCE TO GATHER
-Service treatment records showing injury or complaints
-Imaging (X-ray, MRI, CT)
-Range of motion measurements
-Flare-up documentation per Sharp v. Shulkin
-Buddy statements describing limitations
-Prescription history
-Physical therapy records
-Employment impact documentation

C&P EXAM TIPS (6)
1.Do NOT stretch, warm up, or take pain medication before your exam. The VA needs your baseline limitation.
2.Report your WORST day. DeLuca v. Brown requires documentation of functional loss during flare-ups.
3.Tell the examiner about flare-ups: frequency, duration, estimated ROM loss. Sharp v. Shulkin (2017) requires estimates.
4.Request active, passive, weight-bearing, and non-weight-bearing ROM testing per Correia v. McDonald (2016).
5.If you use assistive devices (brace, cane), bring them.
6.Describe daily activity impact: work, sleep, household tasks.
