Olfactory deficit and Parkinson's: Research papers
- Combination of transcranial sonography, olfactory testing, and MIBG myocardial scintigraphy as a diagnostic indicator for PD
As both tests are easy to perform, noninvasive, and inexpensive, the combination of TCS of the SN and olfactory testing may contribute to early and accurate diagnosis of PD.

- Odor identification deficits identify Parkinson's disease patients with poor cognitive performance.
These findings demonstrate co-occurrence between reduced cognitive function and olfactory deficits in functionally anosmic patients with Parkinson's disease and support the notion of more severe cognitive deficits in this group.

- Olfaction in Parkin heterozygotes and compound heterozygotes: The CORE-PD study
Olfaction is significantly reduced among Parkin mutation heterozygotes with PD but not among their heterozygous relatives without PD. Compound heterozygotes with PD have olfaction within the normal range.

- Olfactory Function in Parkinson's Disease
This article summarises the available literature on olfactory function in PD, which indicates that olfactory tests improve the diagnostic process in these patients; however, it is still unclear which lesion causes olfactory loss in PD.

- Olfactory dysfunction, central cholinergic integrity and cognitive impairment in Parkinson's disease
Olfactory dysfunction is common in subjects with Parkinson's disease. The pathophysiology of such dysfunction, however, remains poorly understood. Neurodegeneration within central regions involved in odour perception may contribute to olfactory dysfunction in Parkinson's disease.

- Olfactory Impairment Predicts Brain Atrophy in Parkinson's Disease
Olfactory dysfunction is a frequent nonmotor symptom in idiopathic Parkinson's disease (PD) and may be considered as an early clinical feature of the disease preceding motor symptoms by years.
