Question: My sister saw brain surgery and she mentioned a patient who had Parkinson's disease. I want to know, what has Parkinson's disease got to do with neurons?

In Parkinson’s disease, a part of the brain becomes damaged, nerve cells in this region get lost over many years. This loss of nervel cells in the bottom bit of the brain results in tremor (involuntary shaking of particular parts of the body), slow movement and stiff and inflexible muscles. Although there is no cure for Parkinson’s disease yet, there are medicines to delay the diseases progression! ☺️

Parkinson’s can also be caused by those neurons malfunctioning… normally they resease dopmine, a neurotransmitter. But sometime the cells can fail to make or release dopamine (and other steps in between) which can cause Parkinson’s. If the neurons are making dopamine and not releasing it, they will eventually die anyway, because dopamine itself is very toxic to cells. Some of the drugs are to replace the dopamine that is missing, but in the long term this approach actually damages the remaining neurons more. A more recent study showed that it is possible to re-generate neurons in this part of the brain using stem cells.
