Two researchers from Washington University in St. Louis and another from Pontificia Universidad Católica in Chile found that daydreaming carries significant creative benefits, especially for those who identify with their profession and care for the work they do.

Findings suggest Alzheimer’s may be due to abnormalities in regions of the brain that are active when people are musing, daydreaming, or thinking to themselves.

The differences, which are especially pronounced in people with dementia, may provide a clear and powerful new method for diagnosing individuals in the very early stages of Alzheimer’s disease.
