Hyposmia correlates with axial signs and gait disorder in Parkinson’s disease: an Italian Olfactory Identification Test study
Olfactory dysfunction is a non-motor symptom and an important biomarker of Parkinson’s disease (PD) because of its high prevalence (> 90%). Whether hyposmia correlates with motor symptoms is unclear. In the pr...

Open AccessCerebrospinal fluid levels of proenkephalin and prodynorphin are differentially altered in Huntington’s and Parkinson’s disease
Proenkephalin (PENK) and prodynorphin (PDYN) are peptides mainly produced by the striatal medium spiny projection neurons (MSNs) under dopaminergic signaling. Therefore, they may represent candidate biomarkers...
