The possible authorisation of new monoclonal antibody therapies for Alzheimer's disease poses challenges for healthcare systems worldwide. In this paper, the Swiss Memory Clinics association (SMC) analyses the available resources and identifies potential health care shortages. Overcoming potential bottlenecks is a challenge that requires action at various levels.

Article Synopsis
  • * The study involved 140 healthy older adults and 49 with mild cognitive impairment, using techniques like APOE genotyping and MRI to measure GSH levels in the brain.
  • * Findings indicated that higher GSH levels are more common in females, while older age and the presence of the APOE4 genotype are associated with increased amyloid levels, highlighting sex-specific differences in GSH levels among older adults.

Introduction: We investigated the interactive associations between amyloid and hypertension on the entorhinal cortex (EC) tau and atrophy and the role of cerebral blood flow (CBF) as a shared mechanism by which amyloid and hypertension contribute to EC tau and regional white matter hyperintensities (WMHs).

Methods: We analyzed data from older adults without dementia participating in the Add-Tau study (NCT02958670, n = 138) or Alzheimer's Disease Neuroimaging Initiative (ADNI) (n = 523) who had available amyloid-positron emission tomography (PET), tau-PET, fluid-attenuated inversion recovery (FLAIR), and T1-weighted magnetic resonance imaging (MRI). A subsample in both cohorts had available arterial spin labeling (ASL) MRI (Add-Tau: n = 78; ADNI: n = 89).

Unlabelled: Gamma-hydroxy-butyric acid (GABA) and glutamate are neurotransmitters with essential importance for cognitive processing. Here, we investigate relationships between GABA, glutamate, and brain ß-amyloid (Aß) burden before clinical manifestation of Alzheimer's disease (AD). Thirty cognitively healthy adults (age 69.

Amyloid beta (Aβ) follows a sigmoidal time function with varying accumulation rates. We studied how the position on this function, reflected by different Aβ accumulation phases, influences APOE ɛ4's association with Aβ and cognitive decline in 503 participants without dementia using Aβ-PET imaging over 5.3-years.
