This article focuses on the change in olfaction and taste with aging. It discusses histopathology with an emphasis on age-related changes, causes of chemosensory dysfunction in the elderly, how to evaluate a patient with dysfunction, useful tests and imaging, clinical consequences of chemosensory impairments, and available treatment options.

The methodology of machine learning with multi-omics data has been widely adopted in the discriminative analyses of schizophrenia, but most of these studies ignored the cooperative interactions and topological attributes of multi-omics networks. In this study, we constructed three types of brain graphs (BGs), three types of gut graphs (GGs), and nine types of brain-gut combined graphs (BGCGs) for each individual. We proposed a novel methodology of multi-omics graph convolutional network (MO-GCN) with an attention mechanism to construct a classification model by integrating all BGCGs.

Although edible flowers have been historically principally used due to their visual appeal and smell, the world is discovering their value as innovative and natural sources of bioactive compounds. L. (CpL), a plant from the Cucurbitaceae family, is widely cultivated for its edible fruits and flowers, which are rich in polyphenols and carotenoids-compounds known for their potent antioxidant and anti-inflammatory properties.

Cognitive function in healthy aging and neurodegenerative diseases like Alzheimer's disease (AD) correlates to olfactory performance. Aging and disease progression both show marked olfactory deficits in humans and rodents. As a clear understanding of what causes olfactory deficits is still missing, research on this topic is paramount to diagnostics and early intervention therapy.

: This study aims to investigate the relationship between olfactory identification (OI) and cognitive impairment by examining OI abilities across various stages of cognitive deterioration. : A total of 264 participants were divided into three groups based on cognitive status: cognitively healthy, subjective cognitive, and mild cognitive impairment. All participants were assessed using the Sniffin' Sticks Olfactory Identification test and a comprehensive neuropsychological test battery.

The locus coeruleus (LC) plays a vital role in cognitive function through norepinephrine release. Impaired LC neuronal health and function is linked to cognitive decline during ageing and Alzheimer's disease. This study investigates age-related alterations in olfactory detection and discrimination learning, along with its reversal, in Long-Evans rats, and examines the effects of atomoxetine (ATM), a norepinephrine uptake inhibitor, on these processes.
