A paired sample t-test for CVLT-three no cost and cued hold off remember performances uncovered considerable variations in between MCI participants and healthy controls, with sizeable dissimilarities viewed amongst their recall performances on these tasks and people observed to own MoCA scores no matter scoring metrics applied, though retrieval effectiveness only relevant to CVLT-3 cued delays.
Those who score improperly on these exams might be referred to the neurologist for even further testing, including blood assessments to detect amyloid or tau amounts - indicators of Alzheimer's disease.
