A movement disorder causing involuntary, jerky movements, often following streptococcal infection.
To support a rating at any level, medical records that document how your Sydenham's chorea presents and how it has changed over time are central. For the lower levels, records showing mild or moderate involuntary movements and their effect on daily tasks would be relevant. For the higher levels of 80% or 100%, records showing severe or progressively worsening symptoms, including how the condition affects your ability to function, carry weight. Because the regulation directs VA to consider rheumatic cause and complications, records linking the chorea to a rheumatic condition such as rheumatic fever, and any records of related heart or joint complications, are also relevant. Statements from you or people who know you describing how symptoms affect your work and daily activities can help show the functional impact at each level.
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.
