The study evaluated the usefulness of the 2018 NIA-AA research framework in a longitudinal memory clinic study, finding that the ATN system is supportive in detecting early AD or mixed dementia, with the majority of patients converting to AD and mixed dementia belonging to A positive ATN groups.
Introduction To evaluate the usefulness of the 2018 NIA-AA (National Institute on Aging and Alzheimer's Association) research framework in a longitudinal memory clinic study with different clinical outcomes and underlying disorders. Methods We included 420 patients with mild cognitive impairment or subjective cognitive impairment. During the follow up, 27% of the patients converted to dementia, with the majority converting to Alzheimer's disease (AD) or mixed dementia. Based on the baseline values of the cerebrospinal fluid biomarkers, the patients were classified into one of the eight possible ATN groups (amyloid beta [A beta] aggregation [A], tau aggregation reflecting neurofibrillary tangles [T], and neurodegeneration [N]). Results The majority of the patients converting to AD and mixed dementia were in ATN groups positive for A (71%). The A+T+N+ group was highly overrepresented among converters to AD and mixed dementia. Patients converting to dementias other than AD or mixed dementia were evenly distributed across the ATN groups Discussion Our findings provide support for the usefulness of the ATN system to detect incipient AD or mixed dementia.
