Dementia

A new study suggests a compound in cannabis could protect the brain from Alzheimer’s disease. Researchers found that treating rats with cannabidiol prevented memory loss and inflammation by activating specific brain receptors.

A new study uses magnetic stimulation to show that brain complexity drops in early Alzheimer’s disease. The findings suggest the condition may be fundamentally linked to a breakdown in the neural networks supporting consciousness.

Is obesity a direct cause of dementia? A massive study using genetic data says yes. Findings published in The Journal of Clinical Endocrinology & Metabolism reveal that high blood pressure mediates this dangerous link.

New research suggests that older adults with chronic sleep issues tend to live shorter lives and spend less time with normal memory and thinking skills.

While ultra-processed foods are linked to higher rates of dementia and anxiety, the MIND diet may offer a powerful shield. A large-scale analysis sheds light on the biological pathways that might explain these opposing effects on brain health.

A new study published in Sleep Health reveals that frequent night waking is linked to immediate reductions in cognitive speed. The findings suggest that sleep continuity may be more critical than duration for aging brains.

Andre Yarham was diagnosed with frontotemporal dementia at just 22. Following his death, his family has donated his brain to medical research, hoping to help scientists understand why this aggressive disease attacks young adults.

A new study published in Nutritional Neuroscience suggests that following the MIND diet is linked to lower levels of Alzheimer’s-related protein buildup in the spinal fluid of adults without dementia.

A new study finds that a signaling pathway is hyperactive in female brains with Alzheimer's, halting the production of new neurons. Blocking this pathway successfully restored regeneration in mice.

A new longitudinal study from Taiwan reveals that while physical disability and cognitive decline fuel each other, physical limitations are a much stronger predictor of future mental decline than vice versa.

Geographic disparities in dementia may be rooted in the past. Researchers discovered that the political orientation of the state where a person grows up predicts their likelihood of developing cognitive decline decades later.

The specific way you breathe during meditation may determine its impact on Alzheimer's risk factors. A recent clinical trial found that slow breathing reduces amyloid beta peptides, while mindfulness with normal breathing tends to increase them.

Why does running help the brain? New research using single-cell sequencing highlights specific genetic pathways restored by exercise.

Researchers analyzing the Framingham Heart Study cohort report that women with longer reproductive lifespans and a history of hormone therapy show signs of better brain health and reduced dementia risk.

New research tracking thousands of people since 1946 suggests that what you eat throughout your entire life, not just in old age, plays a major role in determining your risk of cognitive decline.
