What symptoms characterize Major or Mild NCD due to Parkinson's Disease?

The correct answer highlights that Major or Mild Neurocognitive Disorder (NCD) due to Parkinson's Disease is characterized by core motor features consistent with Parkinson's Disease itself. This diagnosis is grounded in the understanding that Parkinson’s Disease is primarily recognized for its motor manifestations, which include bradykinesia, rigidity, and tremors. These motor symptoms are not just incidental but serve as a crucial diagnostic criterion when considering the neurocognitive aspects of the disorder.

In the context of NCD, patients often exhibit cognitive decline as it relates to the underlying neurodegenerative process associated with Parkinson's Disease. As the disease progresses, cognitive symptoms may arise alongside the hallmark motor symptoms, making it essential to acknowledge the connection between the two. Recognizing both sets of symptoms enables clinicians to provide a comprehensive diagnosis and management plan.

The other options do not encompass the full spectrum of symptoms relevant to this diagnosis. Major or Mild NCD due to Parkinson’s involves both cognitive and motor symptoms rather than only cognitive decline or symptoms unrelated to Parkinson’s. It is also not characterized by multiple unconnected medical conditions or solely by symptoms stemming from substance use.
