New methods of visualizing tissue are presented at the Society for Neuroscience meeting.

In brain samples from people with Alzheimer’s disease, the protein aggregates more strongly bound proteins involved in processing RNA, the same study finds.

New evidence points to a waste-clearing problem in patients’ cells, rather than the accumulation of protein tangles, as the root cause of the neurodegenerative disease.

Evidence is accumulating that breathing contaminated air might impair cognition.

Contaminants in the atmosphere appear to have harmful effects on neurodevelopment and cognitive function.

A growing body of evidence supports the theory that neural hyperactivity and hyperconnectivity precede the pathological changes that lead to neurodegeneration.

Changes in brain waves while snoozing correlate with accumulation of tau and amyloid-β, suggesting that the neural activity disruptions could clue doctors in to early development of the disease.

Damage to the lysosome, the organelle that removes excess proteins, lipids, and other materials, might be at the root of the disease.

Patients who suffer a traumatic brain injury may exhibit abnormally abundant tau protein many years later, a new in vivo imaging technique reveals.
