From what I understand, Parkinson's disease is caused by the death of dopamine producing cells in the substantia nigra, however I don't understand how that causses the symptoms of Parkinson's. I am particularly interested in the tremor aspect of the disease, although it would be great if someone could also explain how the other psychiatric problems arise (dementia, emotional problems and sleep issues).The reason for this question is that I am trying to understand how deep brain stimulation (DBS) is able to stop the tremours in Parkinson's, or at least reduce their severity, and whether DBS could also help in the other symptoms of Parkinson's.What causes the tremors in Parkinson's disease? Why do Parkinson's patients develop dementia, emotional problems and sleep issues?Why does Deep Brain Stimulation alleviate tremors in Parkinson's disease? Can DBS help other Parkinson's symptoms?
How does Parkinson's disease result in tremors?
