Identifying the Neural Link Between Hearing Loss and Dementia

Scientists have discovered the biological "bridge" that explains why hearing loss leads to cognitive decline—and how it changes the very structure of our brains.

Lifetime Lead Exposure Triples Alzheimer’s Risk

Think lead is a problem of the past? New research shows that lead stored in your bones for decades could triple your risk of Alzheimer’s disease. By tracking thousands of adults, scientists have discovered that historical exposure to leaded gas and paint is a "silent" driver of nearly 1 in 5 dementia cases.

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

A new study challenges the long-standing belief that episodic and semantic memory rely on distinct brain systems. Researchers found that retrieving personal memories and general knowledge activates overlapping neural regions, a discovery that could reshape our understanding of dementia.

Brain Stimulation Method Can Evaluate Consciousness in Alzheimer’s Disease

Researchers have determined that a measure of brain complexity, derived from magnetic stimulation and EEG, can effectively evaluate the integrity of conscious processing in patients with Alzheimer's disease. The findings offer a new potential metric for tracking disease progression.

Dairy Consumption Linked to Lower Dementia Risk

A large 25-year study found that people who ate more high-fat cheese and high-fat cream had a lower risk of developing dementia, though the results only show an association—not proof of protection. Participants who consumed the highest amounts of high-fat cheese had a 13% lower dementia risk overall and a 29% lower risk of vascular dementia.

AI Turns Simple EEG Scans Into Accurate Dementia Detectors

New research shows that deep learning can use EEG signals to distinguish Alzheimer’s disease from frontotemporal dementia with high accuracy. By analyzing both the timing and frequency of brain activity, the model uncovered distinct patterns: broader disruption across multiple regions in Alzheimer’s and more localized frontal and temporal changes in frontotemporal dementia.

Mutation in Key Enzyme Triggers Ferroptosis and Childhood Dementia

Researchers have identified how a single mutation in the GPX4 enzyme causes neurons to undergo ferroptosis, leading to severe early-onset dementia. The study provides the first molecular evidence that ferroptosis can directly drive neurodegeneration in the human brain.

Obesity Speeds Alzheimer’s Biomarker by Up to 95 Percent

New longitudinal research shows that Alzheimer’s disease blood biomarkers rise up to 95 percent faster in people with obesity than in those without. While baseline tests initially appeared lower due to blood dilution, long-term tracking revealed a significantly accelerated buildup of neurodegeneration and amyloid pathology.

Shingles Vaccine Linked to 20% Lower Dementia Risk

A large population analysis found that older adults who received the shingles vaccine were significantly less likely to develop dementia over the following seven years. The study exploited a rare age-based rollout policy that closely mimicked a randomized trial, allowing researchers to isolate the vaccine’s true effect.

The Way You Drive Might Signal Mild Cognitive Impairment

Researchers found that long-term driving behavior can reveal early signs of cognitive decline years before clinical diagnosis. Older adults who later developed impairment showed gradual reductions in trip frequency, night driving, and route variety compared to cognitively healthy peers.

One in Two Americans Have Neurological Disorders

A comprehensive national analysis shows that over 180 million Americans—more than half the U.S. population—are living with a neurological disease or disorder. These conditions span the lifespan, from neurodevelopmental disorders to migraines to age-related diseases such as Parkinson’s and Alzheimer’s.
