With Parkinson's, do not brush depression aside
The conclusion of the study that covers pages of scientific data suggests that depression in Parkinson’s disease is real. And, these results might have implications for developing medications and therapies to help cure or at least slowdown Parkinson’s disease.
Further conclusions state that the relationship between aging, depression and Parkinson’s disease is a result of the loss of dopaminergic (dopaminergic is involved in executive functions, learning, motivations, reward, and neuroendocrine control). The loss of norepinephrine, which is a neurotransmitter, is a loss of mobility and preparation for the brain to urge the body for action and movement. It is the fight-or-flight response in the brain and increases arousal and alertness, promotes vigilance and enhances retrieval of memory.
