Neurocognitive disorders, particularly in older adults, significantly affect functional abilities and global health. Physical activity has emerged as a potential non-pharmacological intervention to improve cognitive performance in patients with neurodegenerative diseases. This review specifically addressed the issue of tailored physical activity interventions for individuals with various neurocognitive disorders.

Cerebrospinal fluid (CSF) biomarkers of Alzheimer's disease (AD)-amyloid and tau-are strong prognostic indicators in neurocognitive disorders (NCD). However, it remains unclear whether anticholinergic burden amplifies mortality risk depending on CSF biomarker profiles in cognitively impaired individuals.

While a high number of studies has investigated the use of drug probes to phenotype P-gp activity, identifying endogenous markers remain a not fulfilled challenge. A previous untargeted lipidomic study in healthy volunteers highlighted some sphingolipid species as putative endogenous substrates of P-gp.

The specific role of HHcy in the pathophysiology of Alzheimer's disease (AD) is debated, as most of the suspected mechanisms overlap with those of vascular dementia (VD). The aim of this study was to explore the association between plasma homocysteine (Hcy) levels and cerebrospinal fluid (CSF) biomarkers of AD, as well as brain magnetic resonance imaging (MRI) features.

Our aim was to evaluate the impact on functional performance of a multi-component program entitled "circuit gym", including the use of muscle-strengthening machines specially designed for seniors. This was a single-center interventional study combining endurance, machine resistance and balance exercises, lasting three months.

Objectives: To assess whether knowledge of the results of CSF AD biomarkers was associated with the same gain in diagnostic confidence in older adults > 80 than in younger patients.

Purpose: Polypharmacy is a frequent situation in older adults that increases the risk of drug-drug interactions (DDIs), both pharmacokinetic (PK) and pharmacodynamic (PD). Direct oral anticoagulants (DOACs) are frequently prescribed in older adults, mainly because of the high prevalence of atrial fibrillation (AF). DOACs are subject to cytochrome P450 3A4 (CYP3A4)- and/or P-glycoprotein (P-gp)-mediated PK DDIs and PD DDIs when co-administered with drugs that interfere with platelet function.

Direct oral anticoagulants (DOACs) are now recommended as first-line therapy for this purpose. Apixaban and rivaroxaban are two direct-factor Xa inhibitors whose dosing is based on various factors (age, weight, creatinine, and creatinine clearance) that can affect the pharmacokinetics of the medication.

In older adults, opioids such as oxycodone are often preferred to other analgesics such as tramadol because of a lower risk of delirium. Different parameters, such as inhibition of cytochrome P450 (CYP450) 2D6 and/or 3A4, can potentially lead to pharmacokinetic variations of oxycodone representing a risk of adverse drugs effects or lack of drug response.

P-gp is responsible for several drug-drug interactions encountered in clinical practice leading to iatrogenic hospital admissions, especially in polypharmacy situations. ABCB1 genotyping only reflects an indirect estimate of P-gp activity.

Transcatheter aortic valve implantation allows the treatment of aortic stenosis by implanting an aortic bioprosthesis through a catheter, without surgery. The left atrial appendage occlusion limits the risk of ischemic stroke in patients with atrial fibrillation who have a contraindication to anticoagulants.
