Olfactory dysfunction is a hallmark symptom of COVID-19 disease resulting from the SARS-
CoV-2 virus. The cause of the sudden and usually temporary anosmia that most people …

Abstract Objectives/Hypothesis: To evaluate the utility of olfactory identification tests as
prognostic instruments for Alzheimer's dementia (AD). Study Design: Systematic review …

Neuroimage measures from magnetic resonance (MR) imaging, such as cortical thickness,
have been playing an increasingly important role in searching for biomarkers of Alzheimer's …

Qualitative olfactory dysfunction is characterized as distorted odor perception and can have
a profound effect on quality of life of affected individuals. Parosmia and phantosmia …

Objective: Prior studies indicate that olfactory function may be an early marker for cognitive
impairment, but the body of evidence has been largely restricted to white populations …

In many neurodegenerative diseases and particularly in Parkinson's disease, deficits in
olfaction are reported to occur early in the disease process and may be a useful behavioral …

The frontal cortex is a brain structure that plays an important role in cognition and is known
to be affected in Alzheimer's disease (AD) in humans. Over the past years, transgenic mouse …

Objective There is a need for inexpensive noninvasive tests to identify older healthy persons
at risk for Alzheimer disease (AD) for enrollment in AD prevention trials. Our objective was to …

Olfactory dysfunction is closely related to Alzheimer's disease (AD). Yet the mechanism
behind this dysfunction remains largely unknown. To clarify the relationship between …

Olfactory sensory neurons (OSNs) are the receptor cells for the sense of smell. Although cell
bodies are located in the olfactory mucosa (OM) of the nasal cavity, OSN axons directly …
