A review explains how blood biomarkers are entering Alzheimer's care—and why multiple tests may be needed to capture dementia's complexity.
A UK study links an extra year of compulsory schooling to fewer dementia diagnoses, with the strongest benefit among adults with genetic risk.
Smoke, heat, and disrupted sleep may threaten firefighters' brain health, but evidence linking these exposures to neurodegeneration remains uncertain.
A UCLA study links pesticide exposure to higher Parkinson’s risk, while lab experiments suggest how the chemical may damage brain cells.
An eight-year study links higher sweetener intake to faster cognitive decline, but it cannot show that sugar substitutes cause brain aging.
A new review argues that damaged mitochondria are a shared hub driving neuron loss across five major brain diseases, and it maps the emerging fixes.
A review explores how declining clearance of toxic fat breakdown products may contribute to Parkinson's—and why antioxidants alone may fall short.
A wrist-sensor study of 87,577 adults tied brighter daytime light to a 16% lower dementia risk. Under 42 minutes of bright light a day stood out as a warning sign.
A completed 103-participant trial examined simvastatin's effects on brain markers and cognition, but the supplied abstract reports no results.
A tiny brainstem region once thought to broadcast one signal actually sends targeted messages. The finding could inform Alzheimer's, depression and ADHD treatments.
A review links changes in brain support cells’ fats to inflammation and cell damage, highlighting treatment ideas—not proven prevention strategies.
A completed 120-participant trial explored diet counseling, supplements, and education for brain health. The supplied abstract reports no results.
