Parkinson’s disease is a common, age-related, chronic, progressive disorder caused by loss or degeneration of dopaminergic neurons in the substantia nigra of the midbrain, as stated in the Introduction section.  

There is an increased prevalence and incidence rate of Parkinson’s disease in the elderly. A detailed discussion about the prevalence of Parkinson’s disease and Parkinson’s disease dementia is in the Epidemiology section.

The Pathophysiology section states that the pathologic hallmark of Parkinson’s disease is loss of dopaminergic substantia nigra neurons, with surviving neurons often containing a characteristic cytoplasmic inclusion body (Lewy body). The developmental process of Parkinson’s disease in affected patients is in this section.

The Risk Factors section enumerates the factors that are associated with the development of Parkinson’s disease and Parkinson’s disease dementia.
