SalusRecent studies show that caffeine can reduce sleep quality and hinder the body's recovery, even if a person falls asleep on time and does not notice any obvious sleep disturbances. The response to caffeine is individual and depends on many factors.
SalusA new study has shown that in elderly people with sleep disorders and early signs of dementia, taking high doses of vitamin D is associated with improved cognitive function. This effect was observed only at doses of 5,000 IU per day or higher.
SalusA new study has shown that patients with Parkinson's disease experience changes not only in their sense of smell but also in their reaction to unpleasant odors—they do not hold their breath like healthy individuals do. These characteristics could serve as an additional diagnostic marker for the disease.
SalusNearly half of all dementia cases are linked to modifiable risk factors, such as smoking and high blood pressure. Research has shown that healthy habits can delay the onset of symptoms of Alzheimer's disease and vascular dementia.
SalusA pilot study has shown that reducing the daily eating window may not only help older women lose weight, but can also moderately improve their cognitive functions. Larger-scale studies are needed to confirm these findings.
SalusA new study has found that different microglial responses in the brain may explain why some people are more resistant to dementia in Alzheimer's disease. These findings open up new possibilities for developing therapies aimed at supporting the brain's protective microglial functions.
SalusA new study has shown that the APOE2 gene variant helps neurons protect DNA and slows down cellular aging, thereby reducing the risk of dementia and Alzheimer's disease. These findings open up new possibilities for therapeutic approaches, especially for people with a high genetic risk.
SalusA new study has shown that exceptional memory in older adults cannot be explained solely by a low genetic risk for Alzheimer's disease. Other biological, behavioral, and social factors also play an important role in maintaining cognitive health.
SalusA single dose of psilocybin leads to changes in brain activity and structure that persist for several weeks and are associated with improved well-being and psychological insight. These findings broaden our understanding of psilocybin’s therapeutic potential for mental health disorders.
SalusA two-year study found that omega-3 fatty acid supplements did not improve memory or cognitive function in older adults at risk for Alzheimer's disease. Taking fish oil did not slow age-related changes in the brain compared to a placebo.
Studies show that frequent television viewing in middle age is associated with a reduction in the volume of certain brain regions and signs of damage decades later. Engaging in mentally active tasks while sitting has a more positive effect on brain health than passive TV watching.
SalusA study among elderly individuals has revealed a link between low blood vitamin C levels and a reduction in brain gray matter volume, as well as decreased connectivity in key brain networks. These findings highlight the importance of a balanced diet for maintaining cognitive health in older age.
SalusAmerican scientists have developed an experimental nasal spray that reduces neuroinflammation and restores cognitive function in age-related brain changes. In animal studies, the drug demonstrated improved memory and good tolerability. The next step is clinical trials in humans.
SalusA large-scale study has shown that using hearing aids reduces the risk of developing dementia, especially when the devices are highly effective. High-quality hearing correction provides the greatest protection for the cognitive health of older adults.
SalusA new study has found that hidden internal stress accelerates memory loss in older Chinese Americans. Since this factor can potentially be addressed, researchers recommend developing culturally sensitive strategies to support emotional and cognitive health.
