          Metabolic Syndrome in Midlife Linked to Higher Dementia Risk

          A large-scale study has found that having metabolic syndrome in midlife—marked by excess belly fat, high blood pressure, and abnormal cholesterol or blood sugar—is associated with a significantly higher risk of developing young-onset dementia before age 65. The analysis, based on nearly two million people, showed that the more components of metabolic syndrome a person had, the greater their dementia risk, with women and those in their 40s being most vulnerable.

          How Age, Sex, and Genetics Shape Blood Biomarkers for Dementia

          A new study reveals how age, sex, menopause, and genetics influence key blood biomarkers linked to dementia risk. Researchers analyzed data from over 1,000 people, measuring three biomarkers over a 17-year period and comparing results between those who developed dementia and those who did not.

          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.

          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.

          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.

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.
