Dementia

A study using magnetoencephalography found that Alzheimer’s patients show increased high-frequency brain oscillations, even without epileptic activity. These waveforms may offer a new biomarker for hyperexcitability and help identify those who could benefit from targeted seizure treatments.

New research reveals that mutations in three genes linked to familial Alzheimer’s can predict when symptoms begin, acting like molecular clocks. The study may help improve diagnosis and inform targeted therapies for early-onset forms of the disease.

A novel vaccine targeting a toxic form of tau protein reduced brain atrophy and improved memory in mice and monkeys. The study offers a potentially safer, longer-lasting, and more cost-effective approach than current antibody-based Alzheimer’s treatments.

New research finds that sleep disorders are associated with increased dementia risk. People with insomnia or obstructive sleep apnea were significantly more likely to develop Alzheimer’s disease and vascular dementia, emphasizing the role of sleep health in cognitive aging.

A study in fruit flies suggests that impaired glucose metabolism in glial cells contributes to neurodegeneration in Alzheimer’s. Enhancing glucose transport in these cells reduced inflammation and preserved neurons, highlighting a new potential angle for therapeutic intervention.

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.

Marriage has long been seen as protective for health, but new findings suggest being unmarried might actually reduce your odds of developing dementia.

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.

A new study in Japan found that matcha green tea may improve sleep quality and emotional perception in older adults with cognitive decline.

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.

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.

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.

Scientists have developed a self-administered smell test that could spot early memory problems before symptoms become obvious.

Researchers have developed an affordable system that uses movement data and artificial intelligence to identify mild cognitive impairment with 83% accuracy.

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.
