A non-exclusive subset (n = 107) consented to lumbar punctures to obtain cerebrospinal fluid for \u00df-amyloid<jats:sub>42<\/jats:sub> and Tau protein assessment including cognitively health (n = 75), mild cognitively impaired (n = 22), and Alzheimer\u2019s disease (n = 10). After adjustment for false discovery rate, \u00df-amyloid<jats:sub>42<\/jats:sub> was significantly associated with volumes in the hippocampus (p = 0.043), prefrontal cortex (p = 0.010), precuneus (p = 0.024), and the posterior cingulate (p = 0.002). No association between Tau levels and regional brain volume survived multiple test correction. Secondary analysis was performed to determine associations between MRI brain volumes and CSF protein levels to neuropsychological impairment. A non-exclusive subset (n = 96) including cognitively healthy (n = 72), mild cognitively impaired (n = 21), and Alzheimer\u2019s disease (n = 3) participants underwent Stroop Interference and Boston Naming neuropsychological testing. A higher score on the Boston Naming Test was optimally predicted in a selective regression model by greater hippocampus volume (p = 0.002), a higher ratio of \u00df-amyloid<jats:sub>42<\/jats:sub> to Tau protein levels (p &lt; 0.001), greater posterior cingulate volume (p = 0.0193), age (p = 0.0271), and a higher education level (p = 0.002). A better performance on the Stroop Interference Test was optimally predicted by greater hippocampus volume (p = 0.0003) and a higher education level (p &lt; 0.001). Lastly, impaired cognitive status (mild cognitive impairment and Alzheimer\u2019s Disease) was optimally predicted in a selective regression model by a worse performance on the Stroop Interference Test (p &lt; 0.001), a worse performance on the Boston Naming Test (p &lt; 0.001), along with lower prefrontal cortex volume (p = 0.002) and lower hippocampus volume (p =
