Although aging is associated with clear declines in physical and cognitive processes,
emotional functioning fares relatively well. Consistent with this behavioral profile, two core …

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 …

It was recently proposed that olfaction evolved to aid navigation. Consistent with this
hypothesis, olfactory identification and spatial memory are linked to overlapping brain areas …

In aging, olfactory deficits have been associated with lower cognition and motor function.
Olfactory dysfunction is also one of the earliest features of neurodegenerative disease. A …

The human brain sustains a slow but progressive decline in function as it ages and these
changes are particularly profound in cognitive processing. A potential contributor to this …

Changes in the functional connectivity (FC) of large-scale brain networks are a prominent
feature of brain aging, but defining their relationship to variability along the continuum of …

Odorants are detected by olfactory sensory neurons, which are covered by olfactory mucus.
Despite the existence of studies on olfactory mucus, its constituents, functions, and …

Abnormalities in olfactory function have been identified in a number of neurological and
psychiatric disorders, including Parkinson's disease and schizophrenia. However, little is …

During normal aging process, the smell function declines significantly, starting from the sixth
decade of age. While it has been shown that activity in the central olfactory system of seniors …

Introduction Aging plays a major role in neurodegenerative disorders such as Alzheimer's
disease, and impacts neuronal loss. Olfactory dysfunction can be an early alteration …
