This research investigates the neurological causes of sleep dysfunction in people with myotonic dystrophy, a common multisystem muscular dystrophy. Using mouse models and brain activity monitoring, the study examines how diseased brains lose the ability to compensate for stress, providing new insights into sleep quality, cognition, and disease progression.

This study examines cognitive reserve theory by investigating the relationship between education and cognitive performance across developed and developing countries. Using numeracy and verbal fluency measures, it finds that higher education consistently improves cognition. However, cognitive performance is largely similar across countries once education level is considered, challenging assumptions about educational quality differences.
