Costa Rica confirmed five cases of measles in 2026 and is monitoring more than 290 contacts.

Recent scientific research highlights the critical link between sleep patterns and cognitive health, particularly regarding aging and neurodegenerative risks. A study published in Scientific Reports indicates that sleeping approximately 7.23 hours per night after age 60 is associated with the lowest long-term risk of cognitive decline, demonstrating a U-shaped relationship with sleep duration.

Additionally, research highlighted by HealthDay News in August 2026 suggests that specific sleep disruptions, such as an increased number of micro-awakenings, may serve as an early indicator of Alzheimer's disease and are linked to an individual's genetic risk for the condition. Together, these findings underscore how sleep duration and quality provide vital insights into neurological health and cognitive preservation in older adults.
