Both amygdala (AG) and hippocampus (HC) are integral parts of the olfactory system. The
present study, including a large number of healthy subjects, was performed to compare HC …

The very high sensitivity and specificity of odor identification tasks in discriminating between
Alzheimer's patients and normals suggests that they reflect the presence of underlying …

The aim of this study was to investigate the relationship between olfactory recognition and
morphological changes in olfactory brain regions including the amygdala, hippocampus …

Objective: Alzheimer disease (AD) is a chronic neurodegenerative disorder that affects
millions of individuals worldwide. Symptoms include memory dysfunction and deficits in …

Few population-based studies including younger adults have examined the potential of
olfactory function tests to capture the degree of atrophy in memory-associated brain regions …

Even in early stages, Alzheimer's disease (AD) is associated with olfactory deficit. We
assess the association of volumetric differences in subcortical deep gray matter (DGM) …

Olfactory decline is an early symptom of Alzheimer's disease (AD) and is a predictor of
conversion from mild cognitive impairment (MCI) to AD. Olfactory decline could reflect AD …

Background: Olfactory dysfunction is present since the earliest stage of Alzheimer's disease
(AD). In AD patients, the olfactory impairment has been correlated with atrophy of some …

The olfactory bulb (OB) is considered to be the most important relay station in odor
processing. Involving 125 randomly selected subjects (58 men, 67 women; age range: 19 to …

The study aimed to investigate the volume of the olfactory bulb in smokers. Specifically, we
wanted to see whether environmental influences may exert a negative influence on OB …
