Nasal chemosensory tests: biomarker between dementia with Lewy bodies and Parkinson disease dementia.

CONCLUSIONS: The current study highlights that DLB patients have very poor olfactory and trigeminal detection threshold perfor- mances, which are significantly lower, compared to PDD patients. These results suggest that olfactory testing, using odorants that stimulate both the olfactory and trigeminal systems, could constitute an interesting biomarker and contribute to the differential diagnosis of PDD and DLB patients. Further researches, notably on olfacto-trigeminal interactions, are warranted in these popula- tions to support our findings. PMID: 32830809 [PubMed - as supplied by publisher]
