A new study examining older Black Americans’ perceptions of Alzheimer’s disease has found a lack of awareness of the devastating condition. The authors propose strategies for supporting brain health in this population.

Carnegie Mellon researchers discovered that the motor cortex plays a leading role in controlling movement, guiding striatal activity for both skilled and unskilled actions. By removing the motor cortex in mice, they observed impaired movement.

New research from DANDRITE shows that memories can be strengthened by subsequent unrelated experiences if they evoke strong emotional responses. This challenges the traditional Hebbian model of memory formation.

A study found that lecanemab effectively targets amyloid plaques in brain tissue of people with Down syndrome, who are prone to early Alzheimer's. While promising, the drug also binds to brain blood vessels, raising safety concerns.

New research shows that scavenger cells in the eye develop as early as the embryonic stage, providing new insights into retinopathies.

Participants on a self-directed dietary education program who had the greatest success at losing weight across a 25-month period consumed greater amounts of protein and fiber, a study found.

Adaptive deep brain stimulation could provide round-the-clock personalized care for people with Parkinson’s disease, treating movement problems during the day and insomnia at night.

Researchers at Karolinska Institutet developed a machine learning model, AutMedAI, that predicts autism in young children with 80% accuracy. By analyzing simple developmental milestones and behaviors, the model offers a tool for early diagnosis.

The time of day impacts malaria severity in mice, with nighttime infections leading to milder symptoms. The findings suggest that both host and parasite circadian rhythms influence disease progression.

New research identifies five subtypes of insomnia based on personality and brain circuits. These findings could lead to personalized treatments targeting the distinct vulnerabilities in brain function associated with different insomnia types.
