Higher BMI Linked to Longer Survival After a Dementia Diagnosis

Summary: A long-term study of more than 4,500 older adults reveals that individuals who are overweight or obese when diagnosed with dementia exhibit a significantly lower risk of death than…

Adults With ADHD Face Higher Long-Term Dementia Risk

Summary: A massive study of more than 187,000 older adults enrolled in the NIH’s All of Us Research Program reveals that adults with attention-deficit/hyperactivity disorder (ADHD) face more than quadruple…

Youth Protein TIMP2 Restores Immune Function in the Aging Brain

Summary: Researchers have discovered that the youth-associated protein TIMP2 plays a critical role in maintaining the healthy function of microglia, the brain’s primary immune cells. Supplementing this protein in aged…

Study of Brain Immune Cells Reveals New Clues to Alzheimer’s Disease Progression

Summary: Researchers have mapped over 830,000 brain immune cells, discovering a protective subtype of microglia that expands as Alzheimer’s disease progresses. Driven by the TREM2 molecular pathway, these cells actively…

Alzheimer Genetic Risk Scores Do Not Explain SuperAging

Summary: A new study reveals that exceptional memory in older adults is not driven simply by low inherited Alzheimer’s disease risk. The multi-center study evaluated 142 SuperAgers (adults in their…

Open-Source AI Tools for Alzheimer’s

Summary: Announced at the Alzheimer’s Association International Conference in London, the Consortium for Biomedical Research and Artificial Intelligence in Neurodegeneration (C-BRAIN) has officially launched three open-source AI tools. Built to…

Long-Term Iron Accumulation Strips Neurons of Disease Resilience

Summary: Neurodegenerative conditions like Alzheimer’s and Parkinson’s diseases afflict tens of millions of people worldwide, driven by a complex web of cellular vulnerabilities that scientists are actively racing to untangle.…

Microglial State Transitions Dictate Alzheimer’s

Summary: Researchers unmasked a critical cellular transition that dictates whether Alzheimer’s disease pathology triggers clinical dementia. The research analyzed brain tissue from older adults, including cognitively healthy centenarians, to map…

Hippocampus Predicts Rewards by Reorganizing Memories

Summary: A new preclinical study reveals that the hippocampus does more than just store memories; it actively reorganizes them to predict future rewards. By tracking brain activity over several weeks,…

Brain Stimulation Method Can Evaluate Consciousness in Alzheimer’s Disease

Summary: A new study reports that a brain complexity measure, calculated by recording EEG signals after a magnetic stimulation pulse, is significantly reduced in people with Alzheimer’s disease. This method,…
