Parkinson’s disease is a degenerative condition that develops over time in different stages. Known most for its association with motor skills, which can lead to tremors and slowed movement, many people don’t realize there is a strong link between Parkinson’s and dementia that can affect cognitive abilities.
About half of those with Parkinson’s will be affected by some form of cognitive impairment. As the disease progresses, people living with Parkinson’s will develop more severe memory and thinking problems. This is where Parkinson’s relation with dementia begins.
Unfortunately, one risk factor for Parkinson's disease is age. Although most people with Parkinson’s first develop the disease around 60 years old, about 5 to 10 percent of those with Parkinson's have "early-onset" disease, which can begin before the age of 50.
While Parkinson’s disease and memory loss may not be commonly associated with each other, recent studies have shown that anywhere from 50 to 80 percent of those with Parkinson’s may develop a form of dementia.
