Background: Epilepsy is a chronic disorder affecting all ages but with a peak in the elderly. The association of epilepsy with age can be explained by the predominance of brain diseases with epileptogenic potential (mostly stroke and dementia) and by the effects of the aging process through a number of molecular mechanisms involving networks of neu...
Spatial memory and navigation capabilities tend to decline in normal aging, but few studies have assessed the impact of landmarks on route learning in a large-scale environment. The objectives were to examine age-related effects on visuo-spatial working memory capabilities in various environments and to determine the impact of landmarks in navigati...
In this dynamic causal modeling (DCM) study, we evaluated the effect of age on the effective connectivity of a cerebral network involved in lexical production. Younger and older adults performed an object naming task during fMRI. The DCM was used to explore the interactions between four regions of interest: the occipital cortex, OC; the lateral tem...

Background: The ability to engage in sexual activity and better cognitive functioning are both associated with better health. However, the association between cognitive functioning and sexual activity is understudied. Objective: To examine the association between cognitive functioning with sexual activity and physical tenderness among community-dwe...

Background: With the increasing global population of older adults, there is a need for environmental interventions that directly affect their physical, psychological, and emotional well-being to help them maintain or regain their independence and autonomy – all of which promote longevity. Methods: To better understand potential opportunities and ch...

The insulin and Brain-Derived Neurotrophic Factor (BDNF) signaling in the hippocampus promote synaptic plasticity and memory formation. On the other hand, aging is related to the cognitive decline and is the main risk factor for Alzheimer’s Disease (DA). Nevertheless, a great effort has been made by the scientific community to elucidate the molecul...

The gut microbiota shows a wide inter-individual variation, but its within-individual variation is relatively stable over time. A functional core microbiome, provided by abundant bacterial taxa, seems to be common to various human hosts regardless of their gender, geographic location, and age. With advancing chronological age, the gut microbiota be...
