Statistics
-
One million people in the United States currently live with Parkinson's disease, according to the Parkinson's Disease Foundation.
Cause
-
In people with Parkinson's disease, the dopamine-producing cells die, affecting the level of dopamine circulating in a person's brain. Dopamine is the neurotransmitter responsible for smooth, coordinated movement.

Dementia
-
According to the Fisher Center for Alzheimer's Research Foundation, around 20 percent of people with Parkinson's disease will develop dementia, a slow loss of memory and intellectual functioning. This typically occurs after 70 years of age.
Psychosis
-
During the later stages of the disease, Parkinson's patients may also develop psychosis, a mental break from reality. This may be drug-induced, as the doses of medication increase as the disease progresses.
Depression
-
Around 50 percent of people with Parkinson's disease also have depression, reports the University of Chicago Medical Center. Physicians may treat this mood disorder with selective serotonin reuptake inhibitors.
