Overview Of The Major Types Of Dementia

Parkinson's Disease Dementia

Parkinson's disease is a progressive condition that affects an individual's nervous system and their movements. Symptoms are gradual. Some patients with Parkinson's disease first deal with a slight tremor in their hands. Other symptoms include muscle stiffness, slow movements, speech issues, and the loss of automatic movements. Many individuals with Parkinson's disease will develop Parkinson's disease dementia after a year or two of dealing with Parkinson's disease.

This form of dementia, like the others, involves a significant decline in reasoning and thinking. Patients will struggle to pay attention, make decisions and judgments, and plan steps to completing various tasks. Memory issues are also common. Many individuals with Parkinson's disease dementia will also develop Lewy bodies in their brain. As mentioned, these are deposits of a protein called alpha-synuclein. This is why many experts believe Parkinson's disease dementia and Lewy body dementia are closely connected.
