‘Describe the cognitive, neuropsychiatric and movement deficits associated with Parkinson’s disease and Parkinson’s disease dementia, and critically discuss how they might be related to neuropathology/neurobiology/brain atrophy?’

Neuropsychological topic related to Parkinson’s disease and Parkinson’s disease dementia.

The paper is to critically discuss.

The question is: ‘Describe the cognitive, neuropsychiatric and movement deficits associated with Parkinson’s disease and Parkinson’s disease dementia, and critically discuss how they might be related to neuropathology/neurobiology/brain atrophy?’

Please divide the paper into the subsections of the question

1) Cognitive deficits of PD AND PDD

2) Neuropsychiatric deficits of PD AND PDD

3) Movements deficits PD AND PDD

then how these relate to

1) Neuropathology

2) Neurobiology

3) Brain atrophy

Contemporary papers (within the past 5 years) are preferable whenever possible to account for the most recent and accurate research.
