Progressive neurological disorder with tremors, rigidity, and slow movement (Parkinson’s)
Because the minimum rating is 30% and higher ratings depend on the severity of your residual symptoms, the most useful evidence is anything that documents how Parkinson's disease affects your daily functioning. Medical records showing the clinical diagnosis and ongoing treatment are the foundation. Examination findings that capture motor activity — such as slowing due to apraxia — directly correspond to the motor activity criteria in the rating schedule. Neuropsychological test results showing objective impairment in memory, attention, concentration, or executive functions support higher levels under those criteria. Records reflecting problems with judgment, orientation, communication, or social interaction are also relevant. If you experience neurobehavioral effects such as impulsivity, apathy, or verbal aggression, treatment notes or mental health records documenting those effects and how often they interfere with work or social interaction can support the rating. Statements from you or people who know you describing how symptoms affect your ability to work, manage daily tasks, and maintain relationships help connect the clinical findings to the functional criteria in the schedule.
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.
