What is the typical clinical presentation required for the diagnosis of Parkinson's disease?

In which stage of Parkinson's disease do Lewy bodies spread to the cortex, potentially leading to cognitive and behavior changes?

In which stage of Hoehn & Yahr staging does the disease present as mild/moderate bilateral with some postural instability but still independence?

Which nonmotor symptom is required for the clinical diagnosis of Parkinson's disease, in addition to bradykinesia?

During which stage of Parkinson's disease does the development of motor features occur as Lewy bodies ascend to the midbrain (SNc)?
