Alzheimer's disease (AD) is a progressive neurodegenerative disorder primarily affecting
cognitive functions. However, sensory deficits in AD start to draw attention due to their high …

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 …

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

Background In many neurological disorders, including Alzheimer disease, early olfactory
dysfunction is observed. Objective In order to determine if deficits in olfactory memory are …

Objectives Olfactory disorder is one of the sensory features that reflects a decline in
cognitive function. However, olfactory changes and the discernibility of smell testing in the …

Olfactory dysfunction and atrophy of olfactory brain regions are observed early in mild
cognitive impairment and Alzheimer disease. Despite substantial evidence showing …

Background Dementia has become the main cause of disability in older adults aged≥ 75
years. Cerebral small vessel disease (CSVD) is involved in cognitive impairment (CI) and …

One of the major challenges in the diagnosis of Alzheimer's disease (AD) is to increase the
specificity of the early diagnosis. While episodic memory impairment is a sensitive AD …

Olfactory dysfunction is a common symptom in neurodegenerative disorders and is regarded
as a potential early predictor of impending cognitive decline. This study was undertaken in …

Background: Previous studies have reported that olfactory identification deficits may be the
earliest clinical features of Alzheimer's disease (AD). However, the association between …
