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…
Brain Switch for Recent Memory Retrieval Identified
Summary: A new study has identified the world’s first “neural switch” responsible for selectively retrieving recent memories over past ones. The researchers discovered a specific neural circuit connecting the medial…
Reducing Visceral Fat Protects the Brain for Decades
Summary: A new longitudinal study reveals that the accumulation of visceral fat, the “hidden” fat stored deep within the abdominal cavity, is a primary driver of brain atrophy and cognitive…
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…
Ultra-Processed Foods Erodes Visual Attention
Summary: A new international study identified a direct link between the consumption of ultra-processed foods (UPFs) and a measurable decline in the brain’s ability to focus. The research followed over…
Glass Half Full: Optimism Lowers Your Dementia Risk
Summary: Can your outlook on life actually protect your brain? A massive new study suggests that optimism is a powerful “psychosocial asset” for healthy aging. Researchers analyzed data from over…
Financial Decline Accelerates Brain Aging
Summary: A new study reveals a direct link between poor financial well-being and accelerated cognitive decline in middle-aged and older adults. Researchers found that significant financial deterioration is associated with…
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…
