Alterations in olfactory functions are proposed to be early biomarkers for neurodegeneration.
Many neurodegenerative diseases are age-related, including two of the most common …

Olfactory capacity declines with aging, but increasing evidence shows that smell dysfunction
is one of the early signs of prodromal neurodegenerative diseases such as Alzheimer's and …

Alzheimer's disease (AD) is one of the most prevalent neurodegenerative disorders in the
world. Although there is no known cure for it at the present, preventive drug trials and …

Research studies that focus on understanding the onset of neurodegenerative pathology
and therapeutic interventions to inhibit its causative factors, have shown a crucial role of …

Olfactory functioning involves multiple cognitive processes and the coordinated actions of
various neural systems. Any disruption at any stage of this process may result in olfactory …

Mild cognitive impairment (MCI) is known as an early stage of cognitive decline. Amnestic
MCI (aMCI) is considered as the preliminary stage of dementia which may progress to …

COVID-19 is an ongoing global pandemic caused by the severe acute respiratory syndrome
coronavirus 2 (SARS-CoV-2) virus. Although it primarily attacks the respiratory tract …

A simple screening test to identify the early stages of Alzheimer's disease (AD) is urgently
needed. We investigated whether odor identification impairment can be used to differentiate …

Objective Parkinson's disease (PD) patients generally exhibit an olfactory loss. Hence,
psychophysical or electrophysiological tests are used for diagnosis. However, these tests …

Abstract Slow-gamma (35-45 Hz) phase synchronization and the coupling between slow-
gamma and low-frequency theta oscillations (4–8 Hz) are closely related to memory retrieval …
