G21.4: Vascular parkinsonism
You have symptoms like those that come with Parkinson’s disease.
With Parkinson’s, there is too little of the messenger substance dopamine in certain parts of the brain. The messenger dopamine is important in controlling the body’s movements, for example. A lack of the messenger dopamine makes movements more difficult. The person can then no longer execute certain movements as quickly as normal. As a result, keeping one’s balance may also become difficult. The muscles may also stiffen up. The hands often shake.
Blood vessels in your brain have become narrower. As a result, certain areas in your brain have not been well supplied with blood and have got damaged. As a result of the damaged areas in your brain, you have symptoms like those that come with Parkinson’s.
