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…

Could Your Voice Reveal How Fast Your Brain Is Aging?

Summary: A multicenter study of nearly 3,000 individuals published in Science Advances reveals that machine-learning models can infer a person’s biological age and brain health from vocal patterns. This newly…

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…

Heart Attacks Release Toxin That Damages Brain Function

Summary: Researchers cracked a critical hidden mechanism behind the “heart-brain axis,” revealing how a heart attack physically reshapes brain function to cause depression, anxiety, and cognitive decline. The research demonstrates…

43% of Antipsychotics for Seniors Start in Hospitals

Summary: New research identifies acute and post-acute care settings, such as emergency rooms, hospitals, and skilled nursing facilities, as the primary locations where risky, cognition-altering medications are first prescribed to…

Memory Rewritten: Study Finds No Clear Line Between Episodic and Semantic Retrieval

Summary: A new study into how different parts of memory work in the brain has shown that the same brain areas are involved in retrieving different types of information. The…

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,…

Stress Undermines Brain Circulation, Increases Dementia Risk

Summary: Researchers found that a rare class of neurons—type-one nNOS neurons—plays a central role in regulating brain blood flow and coordinating neural activity in mice. Removing these stress-vulnerable cells caused…

Artificial Sweeteners Tied to Faster Cognitive Decline

Summary: A large study of nearly 13,000 adults found that consuming high levels of certain artificial sweeteners is linked to faster declines in memory and thinking over eight years. The…
