Here's another cite documenting cranial nerves involved in many PwP:

Therefore, we performed a detailed analysis of the alpha-synuclein immunoreactive inclusion pathologies in the brainstem nuclei (Lewy bodies, LB; Lewy neurites, LN; coiled bodies, CB) and fiber tracts (LN, CB) of clinically diagnosed and neuropathologically confirmed PD and DLB patients. As also reported in previous studies, LB and LN were most prevalent in the substantia nigra, ventral tegmental area, pedunculopontine and raphe nuclei, periaqueductal gray, locus coeruleus, parabrachial nuclei, reticular formation, prepositus hypoglossal, dorsal motor vagal, and solitary nuclei.

However, we for the first time demonstrated LB and LN in all cranial nerve nuclei, premotor oculomotor, precerebellar and vestibular brainstem nuclei, as well as LN in all brainstem fiber tracts. CB were present in nearly all brainstem nuclei and brainstem fiber tracts containing LB and/or LN.

These novel brainstem findings can account for or contribute to a large variety of less well-explained PD and DLB symptoms (e.g. gait and postural instability, impaired balance and postural reflexes, falls, ingestive and oculomotor dysfunctions)....
