Beta Brain Waves and ALS: What a Two-Country Replication Found
In a Dutch-Irish ALS replication study, reduced beta ERD and ERS appeared only in the Irish cohort, while stronger beta ERS tracked faster Go responses in both centres.
Gel Turns Brain Astrocytes Into Neurons — Alzheimer's Research
A new lab study used a gel to lower a key protein in astrocytes, converting them into neurons. The technique may point toward replenishing brain cells lost to Alzheimer's.
APOE4 Gene May Be Reversible: How Alzheimer's Risk Damages Brain Vessels
Mount Sinai researchers found APOE4 turns brain blood vessel support cells into scar-producing cells, but blocking one signaling pathway reversed the damage in mice and human tissue models.
Sugar Rationing in Early Life Tied to Lower Dementia Risk
People who experienced World War II sugar rationing in their first 1,000 days of life had a 23% lower dementia risk and a 28% lower Alzheimer's risk decades later, a U.K. Biobank study finds.
Brain Wiring Changes Distinguish Early Alzheimer's from Normal Aging
A study of over 1,000 people shows Alzheimer's drives a unique pattern of brain rewiring, distinct from normal aging, appearing before symptoms and tracking cognition better than amyloid or tau.
Speech Patterns in Memory Tests Predict Cognitive Decline 7 Years Early
Boston University researchers used natural language processing to show that how you speak during a memory test can flag cognitive impairment and forecast decline seven years in advance.
MRI Study Maps How Different Brain Disorders Age the Brain
A 48,000-scan MRI study finds Alzheimer's, MCI, addiction, and psychiatric disorders show distinct patterns of accelerated brain aging, while ADHD and autism show little overall difference.
Hibernating Mice Shed Half Their Synapses and Keep Memories
Hibernating mice lost nearly half the synapses in their memory center, then regrew them within two days — while keeping the memories they had formed beforehand.
Rapamycin Boosts Brain Blood Flow in APOE4 Carriers
A four-week trial found low-dose rapamycin increased cerebral blood flow in healthy middle-aged APOE4 carriers, with the largest gains in women.
Magnetic Headset May Improve Long COVID Brain Fog
A triple-blind pilot trial from Mount Sinai found that an at-home magnetic headset improved working memory, processing speed, and mood in long COVID patients—with benefits lasting a month after treatment.
8-Year Study: More Screen Time Linked to Better Teen Cognition
A Finnish study tracking children for eight years found more screen time was linked to better cognitive processing in adolescence — suggesting what kids do on screens matters most.
Quantum-Inspired AI Maps Brain Hubs in Schizophrenia and Bipolar Disorder
A tensor network machine learning framework identifies stable gray-matter hubs like Heschl gyrus and insular cortex across schizophrenia and bipolar disorder, with bipolar features forming a subset of schizophrenia's.
