Brief Summary
This study includes 35 PD patients who underwent submandibular gland needle biopsy. 25 neurologically healthy patients of the local otolaryngological clinic, in whom submandibular gland needle biopsy was performed due to a clinical indication, serve as controls.

Outcome Measures
Primary Outcomes (1)
Pathologically aggregated α-synuclein in the submandibular gland.
The biopsy was taken with a biopsy needle (diameter 14 g) which was inserted under sonographic control into one of the both submandibular glands. By means of this biopsy method, a biopsy cylinder was obtained from one submandibular gland. The biopsy cylinder which was immediately transported to the Department of Neuropathology. The whole biopsy cylinder was histopathologically investigated for pathologically aggregated alpha-synuclein. Two histopathological results are possible: presence of at least one pathologically aggregated alpha-synuclein in the obtained biopsy cylinder (positive result) or absence of any pathologically aggregated alpha-synuclein in the obtained biopsy cylinder (negative result).
only baseline, no further investigations.
Study Arms (2)
Participants with Parkinson´s disease.
Participants who fulfilled the diagnostic criteria of Parkinson´s disease.
Participants without a neurological disease
25 neurologically healthy patients of the local otolaryngological clinic, in whom submandibular gland needle biopsy was performed due to a clinical indication.
