Olfactory dysfunction in the pathophysiological continuum of dementia

Bathini, Praveen ; Brai, Emanuele ; Alberi Auber, Lavinia

In: Ageing Research Reviews, 2019, vol. 55, p. 100956

Sensory capacities like smell, taste, hearing, vision decline with aging, but increasing evidence show that sensory dysfunctions are one of the early signs diagnosing the conversion from physiological to pathological brain state. Smell loss represents the best characterized sense in clinical practice and is considered as one of the first preclinical signs of Alzheimer’s and Parkinson’s...

Progressive signaling changes in the olfactory nerve of patients with Alzheimer’s disease

Bathini, Praveen ; Mottas, Antoine ; Jaquet, Muriel ; Brai, Emanuele ; Alberi, Lavinia

In: Neurobiology of Aging, 2019, vol. 76, p. 80–95

Olfaction declines with aging and appears to be a prodromal sign of cognitive decline in progressive neurodegenerative diseases. Nevertheless, very little is known about the pathophysiological changes underlying smell loss that may reflect early network dysfunction. A cross-sectional histoanatomical study was conducted on postmortem olfactory nerves of patients with increasing severity of...
