Parkinson's Disease
What is Parkinson’s Disease? This term refers to a condition in which parts of the brain become steadily more damaged and degraded due to the progressive loss of nerve cells in the substantia nigra.
This damage leads to a major reduction in dopamine, and is the primary cause of many of the physical and psychological symptoms associated with the condition. These symptoms can include bouts of severe depression and/or anxiety, as well as problems with balance, sleep, and memory.
The majority of those affected by Parkinson’s Disease will begin to present with symptoms from around the age of 50 onwards, and men are at slightly higher risk of developing the condition than women.
