Scientist discover ancient brain-cleaning system that may break down in Alzheimer’s disease
A surprising discovery in spider brains has led scientists to uncover a hidden waste removal system in the human brain. Its breakdown may explain the progressive neuron loss seen in Alzheimer’s disease, offering a new target for early intervention.
Surprising link found between marriage and dementia
Marriage has long been seen as protective for health, but new findings suggest being unmarried might actually reduce your odds of developing dementia.
Study links organic food consumption to better cognitive function in older adults
New research finds that older adults who eat organic foods perform better on cognitive assessments, and women in particular may be less likely to develop mild cognitive impairment.
Matcha green tea improves sleep and emotional perception in older adults with cognitive decline
A new study in Japan found that matcha green tea may improve sleep quality and emotional perception in older adults with cognitive decline.
Melatonin trial in older adults with cognitive impairment shows strong feasibility, but no clear effects yet
A new study found high-dose melatonin was safe and well-tolerated in older adults with mild cognitive impairment, paving the way for larger trials on its potential to slow cognitive decline.
Adults with ADHD face higher risk of dementia, new study finds
Researchers have found a strong link between adult ADHD and increased dementia risk, raising new questions about how attention disorders affect brain health in old age.
Cognitive flexibility test reveals subtle signs of Alzheimer’s in healthy older adults
Researchers have found that a cognitive flexibility task, combined with brain scans and blood tests, can reveal early Alzheimer’s risk in older African American adults who appear cognitively healthy.
Home-based smell test shows promise in detecting early cognitive decline, study finds
Scientists have developed a self-administered smell test that could spot early memory problems before symptoms become obvious.
Portable movement test uses artificial intelligence to detect early signs of cognitive decline
Researchers have developed an affordable system that uses movement data and artificial intelligence to identify mild cognitive impairment with 83% accuracy.
A small device tracked older adults’ conversations—and revealed a hidden link to brain health
In a study using real-world audio data, scientists found that older adults who speak more during daily life tend to have sharper memory and thinking skills.
These existing medications may help reduce dementia risk, new study suggests
New research suggests that common medications, including antibiotics and vaccines, may help reduce the risk of dementia.
Scientists identify specific cognitive skill linked to longer life in older adults
Researchers have discovered that a specific cognitive skill—verbal fluency—can predict survival in old age better than other mental abilities.
Severe exposure during 9/11 cleanup linked to early-onset dementia in responders
Responders to the 9/11 attacks faced more than immediate danger—new research shows those with severe exposure are at greater risk of developing dementia before age 65.
Environmental features linked to dementia risk and cognitive decline
Researchers have identified links between neighborhood environments and dementia risk, suggesting that where we live may influence long-term brain health.
Semaglutide reduces brain inflammation and improves memory in an Alzheimer’s model
Semaglutide, the active ingredient in Ozempic, may help fight Alzheimer’s. Researchers found it reduces brain inflammation and improves memory in mice with Alzheimer’s-like symptoms.
