The aim of Parkinson’s disease medical treatment is to ensure that signs and symptoms are managed for as long as possible while minimizing adverse effects. Studies show that if care is not instituted at or immediately after diagnosis, the quality of life of a patient deteriorates rapidly.
Increase Dopamine

There are low brain concentrations of dopamine in people with Parkinson’s disease. Dopamine can not be given directly, though, as it can not enter your brain. Medicines will help you control walking, movement, and tremor issues. These drugs increase dopamine or replace it. Levodopa is a natural chemical that passes through the brain and is converted to dopamine, the most powerful treatment for Parkinson’s disease. Anticholinergic drugs have been used to help regulate the tremor associated with Parkinson’s disease for several years.
Side Effects

However, side effects such as poor memory, confusion, delusions, constipation, dry mouth, and impaired urination frequently offset their modest advantages. For short-term relief of the symptoms of moderate, early-stage Parkinson’s disease, doctors can prescribe amantadine alone. Carbidopa-levodopa therapy can also be given to regulate involuntary movements (dyskinesia) caused by carbidopa-levodopa during the later stages of Parkinson’s disease.
