CSF concentrations of β-amyloid 42 (Aβ42) and phosphorylated tau (p-tau) are well-established biomarkers of Alzheimer's disease and have been studied in relation to several neuropathological features both in patients and in cognitively unimpaired individuals. The CSF p-tau/Aβ42 ratio, a biomarker combining information from both pathophysiological processes, has emerged as a promising tool for monitoring disease progression, even at pre-clinical stages. Here, we studied the association between the CSF p-tau/Aβ42 ratio with downstream markers of pre-clinical Alzheimer's disease progression including brain structure, glucose metabolism, fibrillary Aβ deposition and cognitive performance in 234 cognitively unimpaired individuals, who underwent cognitive testing, a lumbar puncture, MRI, 18F-fluorodeoxyglucose and 18F-flutemetamol PET scanning.

Alzheimer's disease (AD), the predominant form of dementia, is a neurodegenerative disorder of the central nervous system (CNS) characterized by a subtle onset and a spectrum of cognitive and functional declines. The clinical manifestation of AD encompasses memory deficits, cognitive deterioration, and behavioral disturbances, culminating in a severe impairment of daily living skills. Despite its high prevalence, accounting for 60-70% of all dementia cases, there remains an absence of curative therapeutics.

Background: Perivascular spaces (PVS) on brain MRI are surrogates for small parenchymal blood vessels and their perivascular compartment, and may relate to brain health. However, it is unknown whether PVS can predict dementia risk and brain atrophy trajectories in participants without dementia, as longitudinal studies on PVS are scarce and current methods for PVS assessment lack robustness and inter-scanner reproducibility.
Methods: We developed a robust algorithm to automatically assess PVS count and size on clinical MRI, and investigated 1) their relationship with dementia risk and brain atrophy in participants without dementia, 2) their longitudinal evolution, and 3) their potential use as a screening tool in simulated clinical trials.

Introduction: Ischaemic stroke, primarily caused by thromboembolic events, typically arises as a consequence of underlying vascular or cardiac pathology. Non-thrombotic embolic strokes, although rare, are increasingly seen in interventional and intravascular procedures. Oxygen-ozone therapy (OOT) is one of the popular treatments for lumbar disc herniation, providing pain relief.

Background And Objectives: In preparation for future clinical trials involving individuals with Alzheimer disease (AD), mild cognitive impairment (MCI), and dementia, it is important to ascertain the widespread impact of symptoms from the direct perspectives of patients and caregivers. In this study, we performed cross-sectional surveys using large-scale patient and caregiver data to identify the prevalence and average impact of symptoms and symptomatic themes experienced by adults with AD, MCI, and dementia. Subsequent analyses were used to determine which demographic and disease-specific factors are associated with more severe disease.
