Advancement of PD Is Reflected by White Matter Changes in Olfactory Areas: A Pilot Study

Medicina, 2021
Loss of sense of smell is a well-known non-motor symptom of Parkinson’s disease (PD). Here, we present insight into the association between PD advancement and equivalents of smell loss in olfactory-eloquent brain areas, such as the posterior cortex and ...
