Why Nostalgic Songs Spark the Brain’s Memory and Reward System

Listening to nostalgic music activates key brain regions tied to memory and emotion, according to a new brain imaging study. Researchers found that songs linked to personal memories engage both the default mode network and the brain's reward circuitry.

Digital Tech May Reduce Dementia Risk

Contrary to fears of "digital dementia," new research finds that using digital technology is linked to a reduced risk of cognitive decline in older adults. A large-scale meta-analysis of over 400,000 participants revealed that digital engagement correlates with a 58% lower risk of cognitive impairment.

Blocking Tim-3 Boosts Microglia in Alzheimer’s

New research reveals that the immune checkpoint molecule Tim-3 plays a critical role in how microglia, the brain’s immune cells, respond to Alzheimer’s disease. While Tim-3 normally helps maintain brain homeostasis, it can also inhibit microglia from clearing harmful plaques that accumulate in Alzheimer’s.

Dad’s Alzheimer’s May Raise Tau Levels in Your Brain

New research reveals that people with a father who had Alzheimer’s may be more vulnerable to the spread of tau protein in the brain, a hallmark of the disease. The study followed 243 individuals with a family history of Alzheimer’s over nearly seven years and found that those with affected fathers, especially women, showed greater tau buildup.

Eye Clues May Reveal Early Dementia Risk

A new study has found that blood vessels in the retina may hold early clues about a person’s risk of developing dementia. Researchers observed that narrower arterioles, wider venules, and thinner retinal nerve fiber layers were linked to higher dementia risk around midlife.

Natural Compound in Kale May Help Treat ALS and Dementia

A natural antioxidant found in foods like kale and berries, kaempferol, may help protect nerve cells and shows promise as a treatment for ALS and dementia. Researchers found that it improves energy production and eases stress within nerve cells, helping maintain muscle function and slow degeneration.

Blood Flow Boosts Brain Stiffness in Key Memory Region

Researchers have discovered that increased blood flow is linked to greater stiffness in the hippocampus, the brain region vital for memory and learning. This is significant because the hippocampus is among the first regions affected by Alzheimer’s disease.

Weight Training May Slow Cognitive Decline and Protect Aging Brains

A new study shows that weight training not only boosts physical strength but also protects the brains of older adults with mild cognitive impairment. After six months of twice-weekly resistance training, participants showed memory improvements and protection against brain atrophy in regions linked to Alzheimer’s disease.

Less Deep Sleep Linked to Brain Shrinkage, Alzheimer’s Risk

New research shows that reduced time in slow wave and REM sleep is associated with smaller brain volumes in regions vulnerable to Alzheimer’s disease. Using sleep studies and brain imaging data from 270 participants, researchers found that poor sleep architecture was linked to brain atrophy over time—particularly in the inferior parietal region, an area affected early in Alzheimer’s.

Smell Test at Home May Sniff Out Early Cognitive Decline

A new study highlights that olfactory testing could offer a simple, cost-effective way to detect early cognitive impairment from home. Researchers found that older adults with mild cognitive issues performed worse on odor identification and memory tasks than cognitively normal individuals.

Type 2 Diabetes Rewires the Brain Like Early Alzheimer’s

New research reveals that Type 2 diabetes may impair the brain’s reward and memory processing in ways that mirror early Alzheimer’s disease. The study focuses on the anterior cingulate cortex (ACC), a brain region responsible for motivation and emotional regulation, and its interaction with the hippocampus.
