The diagnosis of MCI, particularly the amnestic subtype, has often been used to identify patients 78 in the early stages of AD, although not all patients with this diagnosis progress to develop 79 dementia. In recent years, the research community has actively sought to develop improved 80 diagnostic guidelines for the accurate identification of these patients, primarily through the 81 incorporation of various biomarker-based criteria into their framework (i.e., to add anatomic 82 evidence to the somewhat uncertain characterization of MCI). Leading examples of such efforts 83 are the research criteria for prodromal AD, published by the International Working Group for New Research Criteria for the Diagnosis of AD (Dubois, Feldman, et al. 2010), and MCI due to 85 AD by a National Institute on Aging — Alzheimer’s Association working group (Albert, 86 DeKosky, et al. 2011). 87 88 Research diagnoses such as preclinical AD have also been developed by these same groups in an 89 attempt to identify patients even earlier in the disease continuum who are considered at-risk for 90 developing AD dementia because of the presence of certain AD biological hallmarks. Although 91 these criteria rely primarily on the presence of biomarker changes, they also allow for the use of 92 sensitive (albeit yet undeveloped) clinical measures to detect subtle evidence of cognitive 93 decline We acknowledge that many similarities exist between the leading diagnostic guideline proposals 96 for the earliest stages of AD, and we support the concept of enriching trial populations with 97 patients most likely to progress to more overt dementia, using both clinical and biomarker-based 98 criteria. However, the need for an assessment of sensitivity and specificity in identifying patients 99 who do have actual AD in clinical trials, as well as for the validation of the respective component 100 methodologies (e.g., the selection of appropriate cut-points, assessment of assay variability), 101 does not allow the FDA to formally endorse any specific diagnostic frameworks at this time.
