Alzheimer’s Risk Linked to Increased Social Activity, Not Isolation

Contrary to popular belief, a new study suggests that people with a higher genetic risk for Alzheimer’s may become more socially engaged—not less. Researchers analyzed data from over 500,000 individuals and found that higher-risk participants reported lower social isolation and more positive family interactions.

Fast-Track to Happiness: One Week of Micro-Acts Makes a Difference

A new study has shown that just seven days of small, daily acts of kindness and gratitude can significantly improve emotional wellbeing. In the web-based Big Joy Project, nearly 17,600 participants from around the world performed micro-acts like sharing joyful moments and listing things they’re grateful for.

More Social Media, More Depression: Study Links Cause and Effect

A new study has found that as preteens increase their social media use, depressive symptoms also rise—but not the other way around. Researchers tracked nearly 12,000 youth over three years and discovered that increased screen time predicted later depression, while depressive symptoms did not predict more social media use.

Clues in Spinal Fluid Could Unlock Early FTD Diagnosis

Frontotemporal dementia (FTD), a common form of early-onset dementia, is often misdiagnosed due to its overlapping symptoms with psychiatric and neurological disorders. In a new NIH-funded study, researchers identified key protein changes in spinal fluid that may serve as the first specific biomarkers for FTD in living patients.

Psilocybin Shows Promise for Parkinson’s Mood and Motor Symptoms

A new pilot study reveals that psilocybin—the compound found in psychedelic mushrooms—may significantly improve mood, cognition, and motor function in people with Parkinson’s disease. The compound was well tolerated, with only mild side effects, and benefits persisted for weeks after dosing. While the study was primarily designed to test safety, researchers observed meaningful and lasting improvements in multiple symptoms.

Female Hormones Trigger Pain Relief via Immune Cells

Scientists have discovered that female hormones like estrogen and progesterone can trigger immune cells near the spinal cord to release natural opioids, easing pain before it reaches the brain. These immune cells, known as T regulatory cells (T-regs), are located in the meninges and produce the painkilling molecule enkephalin in response to hormonal signals.

AI-Powered Brain Implant Lets Paralyzed Man Control Robotic Arm

A new brain-computer interface (BCI) has enabled a paralyzed man to control a robotic arm by simply imagining movements. Unlike previous BCIs, which lasted only a few days, this AI-enhanced device worked reliably for seven months.

Rapidly Evolving DNA May Explain Human Brain Complexity

A new study reveals that human accelerated regions (HARs)—segments of DNA that evolved much faster than expected—may be key to the brain’s advanced cognitive abilities. Researchers compared human and chimpanzee neurons and found that HARs drive the growth of multiple neural projections, which enhance communication between brain cells.

FDA Approves Adaptive DBS for Parkinson’s Patients

The FDA has approved adaptive deep brain stimulation (aDBS), a breakthrough therapy that adjusts in real time to Parkinson’s disease symptoms. Unlike traditional DBS, which delivers constant stimulation, aDBS monitors brain activity and responds with precise electric pulses to prevent stiffness and involuntary movements.

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.

REM Sleep Delays May Indicate Early Alzheimer’s

Delayed rapid eye movement (REM) sleep may be an early indicator of Alzheimer’s disease. Researchers found that participants with delayed REM sleep had higher levels of toxic proteins associated with Alzheimer’s and reduced levels of brain-derived neurotrophic factor (BDNF), which supports memory.

Maternal X Chromosome Accelerates Brain Aging

New research shows that female mice expressing only a maternal X chromosome experience faster brain aging and cognitive decline compared to those expressing both maternal and paternal X chromosomes. The maternal X accelerates aging in the hippocampus, a key region for memory and learning, and silences certain genes essential for brain health.
