Abstract

Background: Previous studies on perceptual letter-matching have found that younger and older adults showed "fast-same" effects for response time and "false-different" effects for errors but the effects were more pronounced for older adults. According to the Noisy Operator Theory, internal noise in visual processing distorts "same" trials into appearing different whereas distortion for "different" trials does not affect performance. Older adults have a "noisier" representation of items within perceptual processing which can impact perceptual matching. However, EEG measures may provide a more direct measure of letter-matching decisions. Methods: We measured the P300 event-related potential (ERP) amplitude, an index of familiarity in stimulus categorization, and behavioral measures (response time and accuracy) to assess letter-matching performance. Results: Individuals responded faster to "same" trials than to "different" trials but were less accurate. Older adults showed similar P300 amplitudes across trial type whereas younger adults produced a larger amplitude for "same" than "different" trials, suggesting that older adults showed less familiarity for "same" trials than did younger adults – a prediction of the Noisy Operator Theory. Conclusions: These ERP results are consistent with the Noisy Operator Theory – suggesting that an age-related increase in internal noise affected letter-matching performance. [ABSTRACT FROM AUTHOR]

18. Reduced temporal lobe cerebral blood flow is associated with regional white matter damage among apolipoprotein E ε4 carriers.

Author

Abstract

Background: Reduced cerebral blood flow (CBF) is a risk factor for white matter damage. Apolipoprotein E (APOE) e4, a genetic risk factor for Alzheimer's disease and vascular health modifier, is associated with lower CBF. However, it remains unknown if lower CBF is associated with more severe white matter damage among APOE‐e4 carriers. We examine whether associations among regional CBF, cerebrovascular reactivity (CVR), and white matter integrity are modified by APOE‐e4 status in older adults. Method: Vanderbilt Memory and Aging Project participants (n = 313, 73±7 years) underwent 3T brain MRI. Resting grey matter CBF and CVR (CBF response to hypercapnic stimulus, ΔCBF/100*ΔCO2) were quantified in regions of interest from pseudo‐continuous arterial spin labeling (ASL). Fractional anisotropy (FA) was quantified from diffusion tensor imaging in tracts of interest derived from tractography templates. Linear regressions related regional CBF and CVR to tract‐specific FA, adjusting for demographic and vascular variables, regional tissue volume, cognitive status, and APOE‐e4 status. Follow‐up models tested an APOE‐ε4 status x ASL variable interaction term. Result: In main models, lower temporal lobe CBF was associated with lower FA in the occipital lobe, suggesting compromised white matter integrity (p = 0.02). Lower CBF and higher CVR in the occipital lobe were associated with compromised lower FA in all lobes (all p‐values<0.04). Temporal lobe CBF and CVR interacted with APOE‐e4 status, such that lower temporal lobe CBF related to lower FA in the frontal lobe (p = 0.01) and higher temporal lobe CVR related to lower FA in the frontal (p = 0.001) and temporal (p = 0.007) lobes among APOE‐e4 carriers only. Frontal lobe CVR interacted with APOE‐e4 status, such that higher CVR related to lower FA in the frontal (p<0.001) and temporal lobes (p = 0.008) in APOE‐e4 carriers only. Conclusion: Among older adults, APOE‐e4 modifies associations between cerebral hemodynamics and white matter integrity, such that reduced CBF and greater CVR in the temporal lobe are associated with greater white matter damage in APOE‐e4 carriers. APOE‐e4 carriers may be more susceptible to changes in temporal lobe hemodynamics, and vascular changes in the temporal lobe may have a stronger impact on brain health outcomes for carriers compared to non‐carriers.
