Veterans rated for Paramyoclonus multiplex (convulsive state, myoclonic type) may qualify for TDIU if the condition — alone or in combination with other service-connected disabilities — prevents substantially gainful employment. A single disability rated at 60% or higher (or multiple disabilities combining to 70%, with one at 40%) can support a TDIU claim under 38 CFR § 4.16.

Service connection for Paramyoclonus multiplex (convulsive state, myoclonic type) requires three elements: (1) a current diagnosis of the condition, (2) an in-service event, injury, or disease, and (3) a medical nexus linking the current diagnosis to that in-service occurrence. A nexus letter from a treating or independent medical examiner is the most reliable nexus evidence.
