Answer: They are damaging the brain cells
Explanation:
Both diseases, Parkinson's and Alzheimer's have a negative impact on the brain and the body. They are damaging the brain cells which can cause sleep disturbance, hallucinations, dementia, depression, anxiety, and more.
Once the brain cells are damaged, this disease is affecting also the body because the nerve cell communication and neurotransmitters that are important when it comes to body function are located in the brain.
