Levodopa-induced dyskinesia (LID) is a form of dyskinesia associated with levodopa (l-DOPA), used to treat Parkinson's disease. It often involves hyperkinetic movements, including chorea, dystonia, and athetosis. [1] In the context of Parkinson's disease (PD), dyskinesia is often the result of long-term dopamine therapy.
The 2001 Nobel Prize in Chemistry was also related to l-DOPA: the Nobel Committee awarded one-quarter of the prize to William S. Knowles for his work on chirally catalysed hydrogenation reactions, the most noted example of which was used for the synthesis of l-DOPA. [14] [15] [16] Synthesis of l-DOPA via hydrogenation with C 2-symmetric ...
Therefore, when levodopa is introduced, excessive proteins are discouraged, while in advanced stages, additional intake of low-protein products such as bread or pasta is recommended for similar reasons. [20] To minimize interaction with proteins, levodopa is recommended to be taken 30 minutes before meals. [20]
Levodopa crosses the protective blood–brain barrier, whereas dopamine itself cannot. [3] [4] Thus, levodopa is used to increase dopamine concentrations in the treatment of Parkinson's disease, Parkinsonism, dopamine-responsive dystonia and Parkinson-plus syndrome.

Research shows that up to 30 percent of Caucasian men deal with some form of hair loss before they turn 30 years old, while that number is slightly lower for people of other races and ethnicities.
Carbidopa/levodopa, also known as levocarb and co-careldopa, is the combination of the two medications carbidopa and levodopa. [6] It is primarily used to manage the symptoms of Parkinson's disease, but it does not slow down the disease or stop it from getting worse. [6] It is taken by mouth. [6]
