How Does Dopamine Affect Parkinson’s Disease?

In this educational video from Parkinson’s UK, we find out more about Parkinson’s disease. The film explains that Parkinson’s disease develops in the substantia nigra part of the brain when the cells begin to die. These cells produce dopamine and the loss of dopamine in the brain leads to issues with movement.

Cancer drug raises dopamine levels and eases Parkinson’s symptoms in early clinical trial. 

As the disease progresses and the brain has less and less dopamine, the symptoms of the disease become more apparent and the patient develops tremors, difficulty walking, and other issues with movement. Researchers are working on ways to stop or slow down the loss of these dopamine-producing cells so that Parkinson’s disease may be treated and ultimately cured.

    My Parkinson’s disease started 25 years in the GUT with the H. Pyloria and a flu virus. About 6 years later my left leg didn’t move right while running. When my right thumb started shaking 70% of my dopamine was gone. Ma king a slow but definite trip to the brain through the Vegas nerve in the GUT to the Blood-Brain-Barrier to the substantia nigra. I do hope that there is a cure as I love life with my 7 children and 8 grandchildren. I will be 80 in April and do miss running.!!!!!
