Chronic exposure to stress throughout the lifespan has been the focus of many studies on Alzheimer's disease (AD) because of the similarities between the biological mechanisms involved in chronic stress and the pathophysiology of AD. In fact, the earliest abnormality associated with the disease is the presence of phosphorylated tau protein in locus coeruleus neurons, a brain structure highly responsive to stress and perc Read More

Thioredoxin1 (Trx1) is a ubiquitous antioxidant protein that regulates the cell's redox status. Trx1's thiol redox activity protects neurons from various physiological processes that cause neuronal damage and neurodegeneration, including oxidative stress, apoptosis, and inflammation. Several studies have found that direct or indirect Trx1 regulation has neuroprotective effects in the brain, protecting against, preventing, or dela Read More

Background: Alzheimer's disease (AD) and behavioral variant frontotemporal dementia (bvFTD) are important causes of dementia with challenging differential diagnoses in many cases. Addenbrooke’s Cognitive Examination-Revised (ACE-R) is a cognitive battery that may be useful to differentiate the two disorders. Objective: The objectibe of this study is to investigate the value of the ACE-R combined with sociodemogr Read More

Background: Alzheimer's disease (AD) is a well-known neurodegenerative disease that gradually induces neural network dysfunction and progressive memory deficits. Neural network activity is represented by rhythmic oscillations that influence local field potentials (LFPs). However, changes in hippocampal neural rhythmic oscillations in the early stage of AD remain largely unexplored. Objective: This study investigat Read More

Introduction: Sensory impairments (SIs, including visual, hearing, olfactory, and taste impairments) have been individually associated with age-related cognitive function. Little is known regarding their combined associations with cognitive function. Methods: We included 2,931 participants (mean age of 69.1 years) from the National Health and Nutrition Examination Survey (NHANES, 2011-2014) and 10,785 participants (me Read More

Background: Frontal, temporal lobe dementia (FTD) and amyotrophic lateral sclerosis (ALS) are fatal neurodegenerative diseases. Studies have found that CCNF mutations have been found in patients with familial and sporadic ALS and FTD. Behavioural variant frontotemporal dementia (bvFTD) is a clinical syndrome characterized by progressive deterioration of personality, social behaviour, and cognitive function, which i Read More
