G21.1: Other drug-induced secondary parkinsonism
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.
Certain drugs can affect the amount of dopamine in the brain. As a result of these drugs you have got symptoms like those that come with Parkinson’s.
