TL;DR
The results indicate that color confusion in AD patients is inconsistent, and the Stroop should be used with caution in patient populations.
Abstract
Patients with Alzheimer's disease (AD) (n = 36) and normal older adults (n = 36) were individually administered the Stroop Color-Word Test. Eight of 36 (22%) AD patients exhibited confusion between the colors blue and green, while no control subject had difficulty distinguishing among the colors. In a second experiment, a subset of the original sample (15 AD patients and 8 control subjects) was retested using the Stroop. Only 2 AD patients showed color confusion on both test occasions, while 7 AD patients exhibited color confusion on one occasion. No control subject exhibited confusion between colors the second time. These results indicate that color confusion in AD patients is inconsistent. Due to the high incidence of color confusion in AD patients, the Stroop should be used with caution in patient populations.

The criteria proposed are intended to serve as a guide for the diagnosis of probable, possible, and definite Alzheimer's disease; these criteria will be revised as more definitive information becomes available.

The sensitivity of diagnosis for dementia of the Alzheimer type (DAT) without any other diagnosis was 87%, and the specificity was 78%, but the ischemic scale score did not discriminate well between patients with pure multi-infarct dementia and those with both DAT and multi- infarCT dementia.

The changes observed in the patients with Alzheimer's disease were clearly distinguishable from the findings in 10 age-matched controls and represent a sensory-system degeneration that occurs in Alzheimer’s disease.

Because impairment on Stroop color naming and interference tests appears to be a concomitant of normal aging, caution should be exercised when one is interpreting Stroop test results from older patients with suspected cerebral dysfunction.

The importance of partialling out underlying deficits for the understanding of complex cognitive processes in dementia is demonstrated, due to variations in speed-accuracy tradeoff for the patient groups due to differences in information processing deficits, linguistic impairment, and attitudes to errors.

The results were interpreted to mean that in a cohort of printers with low seniority such as this one, neuro-opthalmotoxic effects can be observed earlier than putative neuropsychotoxic effects with the tools at hand.

Life expectancy in the USSR reached 71 years (64.5 for males and 75 for females) in 1964 and then declined to 70 in 1970 and it is possible to estimate that life expectancy declined further to about 68 years in 1983.
