This study examined the trajectories of depression and apathy in (prodromal) Alzheimer's disease patients and found that they were associated with AD biomarkers. Lower A beta(42) and higher tau levels were related to increased probability of depression and apathy over time.
Objectives To examine trajectories of depression and apathy over a 5-year follow-up period in (prodromal) Alzheimer's disease (AD), and to relate these trajectories to AD biomarkers. Methods The trajectories of depression and apathy (measured with the Neuropsychiatric Inventory or its questionnaire) were separately modeled using growth mixture models for two cohorts (National Alzheimer's Coordinating Center, NACC, n = 22 760 and Alzheimer's Disease Neuroimaging Initiative, ADNI, n = 1 733). The trajectories in ADNI were associated with baseline CSF AD biomarkers (A beta(42,)t-tau, and p-tau) using bias-corrected multinomial logistic regression. Results Multiple classes were identified, with the largest classes having no symptoms over time. Lower A beta(42)and higher tau (ie, more AD pathology) was associated with increased probability of depression and apathy over time, compared to classes without symptoms. Lower A beta(42)(but not tau) was associated with a steep increase of apathy, whereas higher tau (but not A beta(42)) was associated with a steep decrease of apathy. Discussion The trajectories of depression and apathy in individuals on the AD spectrum are associated with AD biomarkers.
