- Is Vasomotion in Cerebral Arteries Impaired in Alzheimer’s Disease?
Vasomotion produces diameter changes of comparable amplitude, however at lower rates, and could contribute to these mechanisms of Aβ clearance In spite of potential clinical interest, studies addressing cerebral vasomotion in the context of AD CAA are limited
- Study finds improving blood vessel health in the brain may help combat . . .
If we direct therapeutic strategies towards promoting healthy vasculature and therefore improve clearance of amyloid-beta from the brain, we may be able to prevent or delay the onset of Alzheimer’s disease in the future ”
- Vasomotion Drives Periarterial Drainage of Aβ from the Brain
In 14-month-old APP PS1 mice, vasomotion and clearance along the walls of arterioles were reduced This correlates with the age-related decrease in the number of arterial SMCs and not with the onset of CAA
- Impaired vascular-mediated clearance of brain amyloid beta . . . - Frontiers
Here, we discuss the role of the predominant Aβ clearance protein—low-density lipoprotein receptor-related protein 1 (LRP1)—in the efflux of Aβ from the brain
- Improving blood vessel health in brain may help combat Alzheimers
Researchers have found that very slow spontaneous blood vessel pulsations drive the clearance of substances from the brain, indicating that targeting and improving this process may help to
- Vasomotion Drives Periarterial Drainage of Aβ from the Brain
In this issue of Neuron, van Veluw et al (2020) show that elimination of solutes from the brain along arterial walls is driven by low-frequency arteriolar oscillations and suggest that age-related reduction of this vasomotion may contribute to impaired clearance of Aβ
- Clearance of interstitial fluid (ISF) and CSF (CLIC) group—part of . . .
Establish novel diagnostic tests for AD, CAA, and vasomotion based on our knowledge of IPAD and the fluid dynamics of CSF Establish novel therapies that facilitate IPAD for the elimination of Aβ from the aging brain to prevent or reduce established AD (and CAA?) pathology
- Neurovascular phase coherence is altered in Alzheimer’s disease
Reduced vasomotion can contribute to insufficient delivery of oxygen and nutrients and to reduced clearance of amyloid-beta which is known to aggregate in Alzheimer’s disease
