Background: Alzheimer's disease (AD) is a complex neurodegenerative disorder characterized by progressive cognitive decline, neuroinflammation, and mitochondrial dysfunction. In Alzheimer's, abnormal Mitochondrial Permeability Transition Pore (mPTP) activity may contribute to mitochondrial dysfunction and neuronal damage. Withanolide A, a naturally occurring compound derived from Withania somnifera, have shown potential neuroprotective effects in various neurological disorders.

The current study examines whether administration of a novel, brain-penetrant NOX2 inhibitor (CPP11G & CPP11H) reduces amyloid plaque load and improves AD-associated vascular dysfunction in a male APP-PS1 mouse model of AD.
Method: Intraperitoneal injections of CPP11G (n = 1) or CPP11H (n = 2) three times per week began at 9-10 months of age in the treatment APP-PS1 group (15 mg/kg).

Background: Alzheimer's disease (AD) is a neurodegenerative disorder primarily associated with aging, but manifests as a complex interplay of multiple factors. Decline in sex-hormones, particularly 17-beta estradiol, is linked to the aging process. The risk for onset of AD significantly increases with aging and loss of estradiol.

Background: Hyperbaric oxygen therapy (HBOT) is a treatment in which oxygen-enriched air (up to 100%) is administered to patients in a chamber at a pressure above one atmosphere absolute and is approved for the treatment of T2D ischemic wounds. Type 2 diabetes (T2D) is a risk factor for dementia. Ischemia due to vascular pathology is hypothesized to be an underlying mechanism for this association.

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].
