✓ Peer-reviewed alzhub usefulness score 51 out of 100. Cognitive tests and assessment

Topic: Risk, prevention and care in population studies

The Cognitive Abilities Screening Instrument (CASI) has a score range of 0 to 100 and provides quantitative assessment on attention, concentration, orientation, short-term memory, long-term memory, language abilities, visual construction, list-generating fluency, abstraction, and judgment. Scores of the Mini-Mental State Examination, the Modified Mini-Mental State Test, and the Hasegawa Dementia Screening Scale can also be estimated from subsets of the CASI items. Pilot testing conducted in Japan and in the United States has demonstrated its cross-cultural applicability and its usefulness in screening for dementia, in monitoring disease progression, and in providing profiles of cognitive impairment. Typical administration time is 15 to 20 minutes. Record form, manual, videotape of test administration, and quizzes to qualify potential users on the administration and scoring of the CASI are available upon request.

Why it matters

Describes the Cognitive Abilities Screening Instrument (CASI), a test scored 0 to 100 covering attention, memory, language, judgment and other abilities, which typically takes 15 to 20 minutes. Pilot testing in Japan and the United States supported its use across cultures in screening for dementia. It is a screening tool and does not itself treat dementia.

Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on strength of evidence, so that was left out: it earned 48 of the 95 points we could judge it on, which is 51 out of 100.
