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...

Effects of monoamines and antidepressants on astrocyte physiology: implications for monoamine hypothesis of depression

Marathe, Swananda V ; D’almeida, Priyal L ; Virmani, Garima ; Bathini, Praveen ; Alberi, Lavinia

In: Journal of Experimental Neuroscience, 2018, vol. 12, p. -

Major depressive disorder (MDD) is one of the most common neuropsychiatric disorders affecting over one-fifth of the population worldwide. Owing to our limited understanding of the pathophysiology of MDD, the quest for finding novel antidepressant drug targets is severely impeded. Monoamine hypothesis of MDD provides a robust theoretical framework, forming the core of a large jigsaw puzzle, ...
