Researchers analyzed data from two large studies, finding a 9% risk of dementia within 10 years for newly diagnosed patients and a 27% risk for those diagnosed for an average of six years. Factors increasing dementia risk included older age at diagnosis, being male, and lower education levels.Read More

Researchers found that prediction models can estimate the rate of decline but with some uncertainty. These models could eventually help answer practical questions about quality of life for patients. The findings highlight the potential of new treatments to delay cognitive impairment.Read More

The research, involving 15,323 women, showed that cognitive decline in mothers with low-birth-weight deliveries was equivalent to one to two years of aging. These findings suggest that low-birth-weight deliveries could be a marker for poorer cognitive health in later years. Further research is needed to confirm these results and explore preventive measures.Read More
