Age-Related Olfactory Dysfunction: Epidemiology, Pathophysiology, and Clinical Management

Frontiers in Aging Neuroscience, 2020
Like other sensory systems, olfactory function deteriorates with age. Epidemiological studies have revealed that the incidence of olfactory dysfunction increases at the age of 60 and older and males are more affected than females.

Olfactory Dysfunction in Parkinson’s Disease [PDF]

Neurosignals, 2007
Prior to the onset of the cardinal motor features of idiopathic Parkinson's disease (PD), other manifestations of neurodegeneration such as olfactory dysfunction are often apparent. Characterizing these potential biomarkers of preclinical PD is particularly important in identifying individuals who will go on to develop disabling symptoms, and thus be ...

Position paper on olfactory dysfunction [PDF]

Rhinology journal, 2017
Olfactory dysfunction is an increasingly recognised condition, associated with reduced quality of life and major health outcomes such as neurodegeneration and death. However, translational research in this field is limited by heterogeneity in methodological approach, including definitions of impairment, improvement and appropriate assessment techniques.

Olfactory Dysfunction in Huntington’s Disease

Journal of Huntington's Disease, 2021
Olfactory dysfunction is a common symptom in patients with neurodegenerative disorders, including Huntington’s disease (HD). Understanding its pathophysiology is important in establishing a preventive and therapeutic plan. In this literature review, we cover the physiology of olfaction, its role in neurodegeneration, and its characteristics in patients

Olfactory dysfunction and COVID-19

Operative Techniques in Otolaryngology-Head and Neck Surgery, 2022
Here, we provide an overview of olfactory dysfunction associated with COVID-19. We provide background regarding the organization and function of the peripheral olfactory system. A review of the relevant literature on anosmia and parosmia due to infection with SARS-CoV-2, the virus causing COVID-19, is provided. Specific attention is focused on possible

Olfactory Dysfunction and Glaucoma

Biomedicines
Background: Olfactory dysfunction is a well-known phenomenon in neurological diseases with anosmia and hyposmia serving as clinical or preclinical indicators of Alzheimer’s disease, Parkinson’s disease, and other neurodegenerative disorders. Since glaucoma is a neurodegenerative disease of the visual system, it may also entail alterations in olfactory ...

Olfactory dysfunction and its related molecular mechanisms in Parkinson’s disease

Neural Regeneration Research
Changes in olfactory function are considered to be early biomarkers of Parkinson’s disease. Olfactory dysfunction is one of the earliest non-motor features of Parkinson’s disease, appearing in about 90% of patients with early-stage Parkinson’s disease ...
