Immune Attack on Smell Pathways May Signal Early Alzheimer’s

A fading sense of smell may be one of the earliest warning signs of Alzheimer’s disease, and new research reveals why. Scientists found that microglia, immune cells in the brain, mistakenly remove nerve fibers connecting the locus coeruleus and olfactory bulb—two regions essential for processing odors.

Touch-Processing Brain Layers Age Differently

Researchers found that the touch-processing region of the brain ages in a layered pattern, with some layers staying resilient while others thin over time. High-resolution MRI scans revealed that the middle and upper layers of the primary somatosensory cortex often remain stable or thicken with age, likely due to frequent sensory stimulation.

Intermittent Fasting Boosts Male Libido by Lowering Serotonin

A new study shows that long-term intermittent fasting increases the sex drive of male mice by reducing serotonin levels in the brain. The effect was linked to dietary tryptophan deficiency, which lowers the production of serotonin—a neurotransmitter known to inhibit sexual behavior.

Ancient Viruses in Our DNA May Fuel Dementia

Researchers discovered a potential link between "endogenous retroviruses" present in the human genome and the development of neurodegenerative diseases. Their study found that these ancient viral remnants might influence the spread of protein aggregates commonly associated with certain dementias.

Enriched Experiences Boost Brain Connectivity

A new study reveals the extent to which experiences can affect brain connectivity. The study used a neurochip with over 4,000 electrodes to track neuronal activity in mice brains. The results showed that mice living in an enriched environment had far more interconnected neurons than those living in standard environments.

Combination of ‘Feelings’ and Measurements Suggest Alzheimer’s in the Early Stage

A combination of patient-reported subjective cognitive impairment and measurable clinical symptoms, such as amyloid-beta accumulation in the cerebrospinal fluid, may help in the early diagnosis of Alzheimer's disease.
