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.

Mini-Brain Models Reveal a New Dementia-Linked Protein Pathway

Scientists have discovered a new protein pathway involved in neurodegeneration by studying “mini-brain” organoids made from patients with frontotemporal lobar degeneration (FTLD). They found that the protein GRAMD1B plays a crucial role in managing cholesterol and lipid balance within neurons—processes closely linked to Alzheimer’s and FTLD.

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.

Shingles Vaccine Linked to Lower Dementia Risk

A new study has found that getting vaccinated against shingles may reduce the risk of developing dementia by 20% over seven years. This conclusion comes from a natural experiment in Wales, where vaccine eligibility was determined by birthdate.

ADHD May Raise Dementia Risk

A new study finds that adults with ADHD show brain changes similar to those seen in early-stage dementia, including higher iron accumulation and increased neurofilament light chain (NfL) levels in the blood. Using advanced MRI scans and blood tests, researchers identified elevated iron in key brain regions and signs of nerve damage in ADHD patients compared to healthy individuals.

Changes in Sleep Patterns Could Predict Dementia Risk

A new study finds that women in their 80s who develop increasing daytime sleepiness over five years are twice as likely to develop dementia. Researchers tracked 733 women without cognitive impairment, using wrist devices to monitor sleep and circadian rhythms.

Long-Term NSAID Use Linked to Lower Dementia Risk

A new study finds that long-term use of non-steroidal anti-inflammatory drugs (NSAIDs) is associated with a lower risk of developing dementia. Researchers followed 11,745 adults over 14.5 years and found that those who used NSAIDs long-term had a 12% reduced dementia risk.

Physical Activity Lowers Brain Disease Risk

A large study found that people who engage in moderate to vigorous physical activity are significantly less likely to develop dementia, stroke, anxiety, depression, and sleep disorders. Researchers analyzed data from over 73,000 individuals using wearable devices to track their activity levels, providing objective measurements of movement and sedentary behavior.

Low-Normal B12 Levels Linked to Slower Brain Processing

Even when within the normal range, lower levels of vitamin B12 may contribute to cognitive decline, according to a new study. Researchers found that older adults with lower biologically active B12 had slower cognitive processing and more white matter lesions, despite meeting current nutritional requirements.

Brain Bleeds Double Dementia Risk

Researchers have found that intracranial hemorrhages, or "brain bleeds," double the risk of developing dementia later in life. While ischemic strokes caused by blood clots have long been linked to cognitive decline, this study shows that hemorrhages also significantly increase dementia risk. Using Medicare data from nearly 15,000 patients, scientists observed a two-fold increase in dementia diagnosis within about 5.6 years after a brain bleed.

Oral Microbiome May Influence Cognitive Decline and Brain Health

The microbial ecosystems in our mouths may impact cognitive function as we age, with pathogenic bacteria linked to cognitive decline. Researchers found that beneficial bacteria, such as Neisseria, are associated with improved memory and attention, while harmful bacteria like Porphyromonas correlate with mild cognitive impairment.
