New diagnostic criteria and guidelines for Alzheimer’s disease published for first time in 27 years

New criteria and guidelines for the diagnosis of Alzheimer’s disease have been published — for the first time in 27 years — by three expert workgroups spearheaded by the Alzheimer’s Association and the National Institute on Aging (NIA) of the National Institutes of Health (NIH).

The workgroups published four articles including ready-to-use clinical diagnostic criteria for Alzheimer’s disease dementia and mild cognitive impairment (MCI) due to Alzheimer’s. A research agenda was proposed for preclinical Alzheimer’s. The use of biomarkers in Alzheimer’s dementia and MCI due to Alzheimer’s was also proposed as a research agenda only, and is not intended for application in clinical settings at this time.

The articles — collectively, the National Institute on Aging/Alzheimer’s Association Diagnostic Guidelines for Alzheimer’s Disease — expand the definition of Alzheimer’s to include two new phases of the disease: (1) presymptomatic and (2) mildly symptomatic but pre-dementia, along with (3) dementia caused by Alzheimer’s. This reflects current thinking that Alzheimer’s begins creating distinct and measurable changes in the brains of affected people years, perhaps decades, before memory and thinking symptoms are noticeable.

“It is our hope that incorporating scientific knowledge gained and technological advances made over the past quarter century will improve current diagnosis, bring the field closer to earlier detection and treatment and, ultimately, lead to effective disease-modifying therapies,” said William Thies, Ph.D., Alzheimer’s Association chief medical and scientific officer. “Development and publication of these articles is a major landmark in the field. That said, publication of these articles is not yet the end of the process of developing new diagnostic criteria for Alzheimer’s, but is another major step in the process.”

“The new guidelines reflect today’s understanding of how key changes in the brain lead to Alzheimer’s disease pathology and how they relate to the clinical signs of mild cognitive impairment and Alzheimer’s disease dementia,” said Creighton Phelps, Ph.D., program director of the Alzheimer’s Disease Centers Program at the National Institutes of Health. “We are also beginning to be able to detect these changes at a preclinical stage, long before symptoms appear in many people. With further research on biomarkers, as set forth in the new guidelines, we may ultimately be able to predict who is at risk for development of mild cognitive impairment and Alzheimer’s dementia, and who would benefit most as interventions are developed.”

The proposed new Alzheimer’s disease diagnostic guidelines were published online today by Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association. Hard copy publication is scheduled for the May 2011 issue.
