Hyposmia in Parkinson’s disease; exploring selective odour loss
npj Parkinson's DiseaseSmell loss is a frequent and early manifestation of Parkinson’s disease (PD), serving as a sensitive - albeit nonspecific - clinical biomarker1. The notion that PD causes odour-selective hyposmia has been debated for three decades.

Visual Analog Scale and Olfactory Objective Tests in Hyposmia Patients: Is There a Link? [PDF]
, 2023 Introduction Olfactory dysfunction (OD) is often a devaluated sensorial affection. The objective evaluation of this dysfunction does not evaluate its compromise in patients' daily life.

Intranasal sodium citrate solution improves olfaction in post-viral hyposmia [PDF]
, 2016 Background: Calcium plays an integral role in olfactory signal transduction, including feedback inhibition. Sodium citrate acts as a calcium sequestrant and when applied intranasally, reduces free calcium available for feedback inhibition, which should ...

Unawareness of hyposmia in patients with idiopathic Parkinson’s disease
Annals of Movement Disorders, 2020 BACKGROUND: Loss of olfaction is a hallmark of neurodegenerative disorders such as idiopathic Parkinson’s disease (PD) and it may precede the clinical syndrome of PD by many years. Olfactory bulb is probably the earliest site of pathology in PD.
