Weeklong improved colour contrasts sensitivity after single 670 nm exposures associated with enhanced mitochondrial function

Mitochondrial decline in ageing robs cells of ATP. However, animal studies show that long wavelength exposure (650–900 nm) over weeks partially restores ATP and improves function. The likely mechanism is via long wavelengths reducing nanoscopic interfacial water viscosity around ATP rota pumps, improving their efficiency. Recently, repeated 670 nm exposures have been used on the …

Dual #sensory impairment in older adults and risk of #dementia from the GEM Study

Hearing and vision loss are independently associated with dementia, but the impact of dual sensory impairment (DSI) on dementia risk is not well understood.. ..DSI was significantly associated with higher risk of all‐cause dementia (hazard ratio [HR] = 1.86; 95% confidence interval [CI] = 1.25‐2.76) and Alzheimer's disease (HR = 2.12; 95% CI = 1.34‐3.36). …
