For the first time in 27 years, clinical diagnostic criteria for Alzheimer’s disease dementia have been revised, and research guidelines for earlier stages of the disease have been characterized to reflect a deeper understanding of the disorder.
The National Institute on Aging/Alzheimer’s Association Diagnostic Guidelines for Alzheimer’s Disease outline some new approaches for clinicians and provide scientists with more advanced guidelines for moving forward with research on diagnosis and treatments. They mark a major change in how experts think about and study Alzheimer’s disease. Development of the new guidelines was led by the National Institutes of Health and the Alzheimer’s Association.
