Neurological disorders with symptoms like Parkinson’s disease (e.g., tremor, slow movement)
Because the regulation sets a single minimum rating of 30% with no additional tiered criteria for paralysis agitans under diagnostic code 8004, the evidence needed centers on establishing the presence and service connection of the condition rather than distinguishing between rating levels. Medical records that document a diagnosis of parkinsonism are central. Neurological examination findings, including notes about tremor, rigidity, bradykinesia, or balance problems, help confirm the diagnosis. Records from treating physicians or specialists showing the ongoing nature of the condition also support the claim. Statements from you or people who know you describing how symptoms affect your ability to work or carry out daily activities can provide useful context. Since the condition carries a set minimum once diagnosed, the diagnosis itself is the critical threshold the evidence must establish.
Conditions that are often caused or made worse by this one. If you have any of these, they may be claimable as secondary service connection.
