Alzheimer’s Disease (AD) is a type of dementia very common in the elderly. A growing body of recent evidence has linked AD pathogenesis to Copper (Cu) dysmetabolism in the body. In fact, a subset of patients affected either by AD or by its prodromal form known as Mild Cognitive Impairment (MCI) have been observed to be unable to maintain a proper balance of Cu metabolism and distribution and are characteriz Read More

Background and Objective: Type 2 Diabetes (T2D) patients are more prone to develop Alzheimer’s Disease (AD). We have previously shown that Glucagon-like peptide-1 receptor agonist exendin-4 (Ex-4) reduces tau hyperphosphorylation in T2D animals through upregulating insulin signaling, and peripheral injected Ex-4 increases insulin levels in the T2D brain. This study aims to further clarify whether the elevated insulin in th Read More

Background: The brain-gut-microbiome axis has emerged as an important pathway through which perturbations in the gut and/or microbial microenvironment can impact neurological function. Such alterations have been implicated in a variety of neuropsychiatric disorders, including depression, anxiety, and Alzheimer’s Disease (AD) and the use of probiotics as therapy for these diseases remains promising. However, Read More

Background: Cerebrospinal Fluid (CSF) biomarkers are associated with conversion from mild cognitive impairment to Alzheimer’s Disease (AD), but their predictive value for later end-points has been less evaluated with inconsistent results. Objective: We investigated potential relationships between CSF amyloid-β1-42 (Aβ42), Phosphorylated tau (P-tau), and Total tau (T-tau) with time to Nursing Home Placement (NHP) and lif Read More

Background: The dopaminergic system is functionally compromised in Alzheimer’s Disease (AD). The activity of Monoamine Oxidase B (MAOB), the enzyme involved in the degradation of dopamine, is increased during AD. Also, increased expression of MAOB occurs in the postmortem hippocampus and neocortex of patients with AD. The MAOB rs1799836 polymorphism modulates MAOB transcription, consequently influ Read More

Background: Alzheimer’s Disease (AD) is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills. The ability to correctly predict the diagnosis of Alzheimer’s disease in its earliest stages can help physicians make more informed clinical decisions on therapy plans. Objective: This study aimed to determine whether the unsupervised discovering of latent classes of subjects with Mild Cognitive I Read More
