Exposure to PM 2.5 pollution linked to brain atrophy and memory decline
Older women exposed to higher levels of air pollution were more likely to experience greater memory decline and Alzheimer's-like brain atrophy compared with those exposed to cleaner air.... Read More...
Inflammatory processes drive progression of Alzheimer’s and other brain diseases
The NLPR3 inflammasome and the inflammatory response it triggers play a critical role in the emergence of tau pathology. ... Read More...
Predicting Alzheimer’s disease-like memory loss before it strikes
Sharp-wave ripple activity in the brain may be an early biomarker for Alzheimer's disease before cognitive impairment begins.... Read More...
Long-term blood pressure variation and risk of dementia
Patients who experience substantial changes in blood pressure over time have an increased risk of developing dementia.... Read More...
Potential vitamin and Alzheimer’s drug produced in yeast
Researchers were able to produce 0.6 grams of ergothioneine, a natural amino acid that has promising effects on Alzheimer's disease in animal studies, per liter of yeast broth via a small scale fermentation process.... Read More...
Why music makes us feel, according to AI
Artificial intelligence helps shed light on how people's brains, bodies, and emotions react to listening to music. Music influences parts of the auditory cortex, including the Heschl's gyrus and superior temporal gyrus, specifically responding to pulse clarity. Changes in dynamics, rhythm, timbre, and the introduction of new instruments cause an uptick in the response. The study also identified the best song types for the perfect workout, sleep, and study.... Read More...
Key gene in familial Alzheimer’s disease regulates neuronal development
Researchers identify a new cell mechanism that connects Alzheimer's disease and cancers.... Read More...
Number of people with dementia will double in twenty years
A new report projects the number of people living with dementia in the US will double to 13 million by 2040. The report estimates that the number of women diagnosed with dementia will rise to 8.5 million, and the number of men with dementia will reach 4.5 million.... Read More...
How Alzheimer’s disease spreads through the brain
Tau buildup associated with Alzheimer's disease is not, in itself, harmful, but the cellular process it disrupts kills neurons.... Read More...
Linguists track impact of cognitive decline across three decades of one writer’s diaries
Reviewing over thirty years of diaries from a patient diagnosed with Alzheimer's disease, linguists discover how writing style changes as dementia progresses.... Read More...
Study pinpoints Alzheimer’s plaque emergence early and deep in the brain
Researchers use SWITCH technology to label amyloid plaques in mouse models of Alzheimer's disease so they could be imaged in fine detail at different ages. They were consistently able to see the plaques first emerged in deep brain structures and tracked circuits, such as the Papez memory circuit, to spread throughout the brain as the animal aged....
