Parkinson’s Disease and the Brain’s Chemistry
Parkinson’s disease-related depression may be brought on by:
- psychological factors, these include fear and social isolation
- biological factors, these include sudden changes in the brain chemicals. It could also be linked to having a history of mental health issue few years before the diagnosis of Parkinson.
- Environmental factors, these may include stress and side effects of certain medications.
Dopamine, norepinephrine, and serotonin production are all impacted by Parkinson’s disease in particular regions of the brain.
The mood, energy level, sleep, motivation, and appetite are all influenced by these chemicals. Low concentrations of these chemicals can have an impact on one’s mood and even cause depression.
Dopamine also aids in controlling how a person moves. Parkinson’s disease physical symptoms are caused by low dopamine levels.
According to Research
Before Parkinson’s disease physical symptoms become obvious, depression may first manifest.
According to a previous study from 2013, those with a diagnosis of depression had a 3.24 times higher risk of developing Parkinson’s disease than those without.
In a 2015 research, it was shown that depression may be a precursor to Parkinson’s disease or a risk factor for the disorder.
The Michael J. Fox Foundation [5] researchers think that depression in persons with Parkinson’s disease is a result of low serotonin levels in their brains. The investigation into this connection is still ongoing.
