Parkinson's disease and depression do occur simultaneously, according to studies revealed in an article in The Washington Post.

A 2012 National Parkinson Foundation study that a good number of 61% of patients diagnosed with Parkinson's live with depression one way or another.

Parkinson's disease and depression both produce the absence of dopamine in the brain, according to experts.

This revelation that connects Parkinson's disease and depression was validated by Joyce Oberdorf, NPF's CEO.

She reportedly said, according to Washington Post:

"Dopamine is a feel-good chemical. If you are low in dopamine, you are not going to feel so good.

"There are [also] other neurotransmitters that can be low."

Experts have also found that individuals that have just received Parkinson's diagnosis often exhibit anxiety, fatigue, non-caring attitude and, of course, depression.

A Raymond and Ruth Perelman School of Medicine at the University of Pennsylvania revealed that 13.9 Parkinson's patients experienced depression prior to being diagnosed with the disorder.

Within the 2 year survey, patients with depression and Parkinson's disease did not receive treatments for their depression.

Patients suffering from depression and Parkinson's should take note to get the optimal professional help they need. Failure to do may result in a more severe or complicated health conditions. Patients need to take initiative in caring for their health as soon as they feel the symptoms of any disorder to prolong longevity.
