If you notice a decline in your sense of smell, there may be reason for concern. Olfactory function naturally decreases with age, and its loss can also be an early indicator of neurodegenerative disorders. New research links a declining sense of smell to a faster accumulation of Alzheimer’s-related brain changes observed in brain scans.
Everywhere in our surroundings, minuscule plastic fragments invade the human body daily through foods and liquids we consume, and airborne particles we inhale. These pervasive invaders spread throughout every organ and tissue, reaching even the brain, where buildup may spark symptoms resembling Alzheimer's disease. A new study revealed concerning levels of microplastic buildup in the human brain.
A recent study suggests that consuming high-fat foods for just a few days can trigger issues, including cognitive decline. Availability of brain glucose is rapidly and reversibly reduced, activating inhibitory neurons and disrupting memory formation. The results highlight the significant role of nutrition in contributing to cognitive decline and the development of Alzheimer’s disease.
A groundbreaking study uncovers a surprising link between the brain and obesity and has revealed a deeper understanding of what’s fueling the obesity epidemic. Even short-term intake of ultra-processed foods can significantly disrupt the brain’s response to insulin, potentially paving the way for obesity and Type 2 diabetes.
A recent study found that certain sugar substitutes may have unforeseen negative effects on long-term cognitive health. It revealed that heavy consumption of specific artificial sweeteners is associated with accelerated cognitive decline in adults.
Dietary fat is a vital component of our diet, serving as a dense energy source, aiding in vitamin transport, and, when stored, cushioning organs and insulating the body. A fatty meal might feel like a harmless treat. However, new research suggests that just one high-fat meal could restrict brain blood flow, possibly raising the chances of stroke and cognitive decline.
For a long time, high "good" cholesterol levels have been praised for their cardiovascular benefits and associated with a decreased risk of disease. However, recent findings indicate that there might be a downside to having excessive amounts of this health marker.
Aging frequently comes with a variety of comorbid conditions, among which dementia stands out as particularly daunting, given the difficulties in developing effective treatments. In light of these challenges, focusing on modifiable risk factors that could diminish the risk of this ailment presents a more practical strategy. Obesity has been pinpointed as one such factor.
Staying up late with insufficient or low-quality sleep may endanger brain function, particularly for those with higher education. A new study involving adults in their middle and later years revealed that well-educated people who frequently stay up late may face a decline in cognitive function. The research indicates that individuals with lower education levels may have work schedules that permit more sleep.
Dementia is a growing global health challenge that takes a significant toll on both individuals and society. With no cure yet available, finding ways to slow its progression or reduce the risk of developing it is critical for supporting healthy aging. Now, new research points to weight training as a potential way to help protect the brain from dementia.
Adequate sleep is crucial for overall health. Insufficient sleep often leads to heightened cognitive deficits. A recent study reveals that older adults with insomnia face a higher risk of memory decline and long-term cognitive impairments, which can lead to dementia. The study utilized a large dataset and primarily focused on sleep disorders.
A new brain imaging study indicates that ultra-processed food consumption increases hunger and overeating resulting in weight gain. This is concerning and sparks worries that these widespread products may fundamentally reshape our eating patterns. This may be a result of altered brain structure by changing neural pathways.
