Diagnosis of Parkinson's Disease Dementia
There is no definitive medical test that confirms cognitive decline or dementia in Parkinson's disease. The most accurate way to measure cognitive decline is through neuropsychological testing.
Imaging studies: Generally, brain scans such as CT scan and MRI are of little use in diagnosing dementia in people with Parkinson's disease. Positron emission tomographic (PET) scan may help distinguish dementia from depression and similar conditions in Parkinson's disease.
