Moreover, the degree to which tauPET deposition is left or right lateralized is associated with language versus behavioral impairment respectively.  \nMethod: Participants with tau-PET data (n = 250; cognitively normal participants [CU; n = 143]; individuals with a consensus diagnosis of mild cognitive impairment [MCI; n = 79], dementia [DEM; n = 27], or otherwise not classified [OTHER; n = 1] enrolled in the Wake Forest ADRC(Table1). Participants completed an annual battery of cognitive assessments including the Uniform Data Set (UDSv3, NACC), MMSE, CDR, a modified PACC5, NBI-MPIQ, and MINT. Tau-PET (SUVr) was quantified globally, regionally (entorhinal cortex, meta-temporal), and according to BRAAK stage. Tau-PET laterality indices were generated from these same regions. General linear models tested for associations between tau-PET deposition or tau-PET laterality with cognitive status and performance on UDSv3 assessments.  \nResult: Overall, Tau-PET deposition differed by cognitive status (CU \u003C MCI \u003C DEM; all p \u003C.05) and was associated with poorer cognition across assessments evaluated (all p \u003C.05; Table 1, Figures 1and 2). Associations were driven by tau-PET+ participants irrespective of the threshold imposed or ROI used. Tau-PET lateralization was detected in ∼23% of participants globally using a lenient criteria (e.g. SD3 1; LEFT: 15%; RIGHT: 8%; Table 1), but did not differ by cognitive status (p = . 17) and was not associated with cognition.  \nConclusion: Overall, increased Tau-PET was associated with poorer cognition and differed by cognitive status as expected. Due to the small number of participants with detectable levels of laterality, we did not find any association between laterality and cognition. In future work we plan to quantity tau pet patterns at the voxel level  \nThis is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.  \n© 2025 The Alzheimer’s Association.
