In the cross-sectional population study of 411 subjects aged 35-64 years and longitudinal 5.5-year follow-up of 157 aged 20-54 years, a relationship was examined between pulse blood flow to the cerebral vessels, their tone as assessed by rheoencephalography and resistance to arterial hypertension, coronary heart disease, and brain vascular lesions. The proportion of healthy persons (without the above-mentioned diseases) was shown to be larger if the pulse blood flow to the cerebral vessels was higher and their tone was lower. In the longitudinal study, the probability to remain healthy was demonstrated to be increased with elevated pulse flow to the cerebral vessels.

Alzheimers Dement

Background: Genetic studies indicate a causal role for microglia, the innate immune cells of the central nervous system (CNS), in Alzheimer's disease (AD). Despite the progress made in identifying genetic risk factors, such as CD33, and underlying molecular changes, there are currently limited treatment options for AD. Based on the immune-inhibitory function of CD33, we hypothesize that inhibition of CD33 activation may reverse microglial suppression and restore their ability to resolve inflammatory processes and mitigate pathogenic amyloid plaques, which may be neuroprotective.

Background: Early detection of Alzheimer's disease (AD) can improve prognosis, given new anti-amyloid therapies. Both positron emission tomography (PET) and magnetic resonance (MR) imaging biomarkers are currently used (1). 48F-Fluorodeoxyglucose-PET (FDG-PET) can detect neurodegeneration-related hypometabolism but is costly and not easily accessible (2).

Alzheimers Dement
December 2024
Tulane University, New Orleans, LA, USA.
Background: Vascular dementia (VaD), the second most common cause of dementia, is characterized by cognitive decline due to reduced cerebral blood flow and blood-brain barrier disruption. Current evidence demonstrates that not only are VaD patients at higher risk of severe COVID-19 illness and mortality, but also that pre-existing cognitive dysfunction/dementia is associated with increased COVID-19 incidence. Conversely, SARS-CoV-2 infection alone worsens dementia-related mild cognitive impairment (MCI) and increases risk of cognitive decline, supported by similar fMRI findings demonstrating hypoperfusion.

Alzheimers Dement

University of Minnesota Duluth, Duluth, MN, USA.
Background: Regulated breathing is increasingly recognized as a vital component in enhancing cognition. Scientific studies suggest that intentional and controlled breathing techniques, such as deep and rhythmic breathing, can promote relaxation, reduce stress, and improve oxygen flow to the brain [1, 2]. Consequently, this may contribute to heightened cognitive function, better concentration, and increased mental clarity, accentuating the importance of incorporating mindful breathing practices as a potential avenue for cognitive improvement [3].
