ICD-Code G20.21: Primary Parkinson disease with severest impairment With fluctuations
You have Parkinson’s disease.
With Parkinson’s disease, certain parts of the brain do not have enough dopamine. Dopamine is a chemical messenger that works mainly in the brain. Dopamine is important in controlling the body’s movements, for example. A lack of dopamine makes movement more difficult. As a result, it may no longer be possible to perform certain movements as quickly as normal. Keeping one’s balance may also become difficult as a result. Muscles may also stiffen up. The hands may possibly shake.
You have severe symptoms from the Parkinson’s. You may no longer be able to walk independently or may need a wheelchair. You may also need help with everyday tasks. Over the course of a day, the symptoms of your Parkinson’s disease vary from more to less severe.
