Use of the Automatic Clock Drawing Test to rapidly screen for cognitive impairment in older adults, drivers, and the physically challenged Sandy Helene Straus 1 *
The Clock Drawing Test (CDT) is a widely used cognitive assessment in the Western hemisphere and in other parts of the world. It is used as a screening tool to detect cognitive impairment, patient pathology, brain lesion development, and various forms of dementia and psychiatric disorders, yet various methods, scoring, recording, and reporting techniques of the CDT lead to subjectivity. The administration of the CDT on paper proves unfeasible, especially in hospitals, and transportation licensing bureaus, and driver’s license agencies where thousands or millions of older and at-risk adults should receive annual cognitive screenings. Also, numerous older adults with vision impairment and physical disabilities who are unable to draw or hold a writing instrument are unable to take the CDT. These obstacles limit the application of the CDT to clinical environments, trained examiners, and physically able older adults. The Automatic Clock Drawing Test TM (ACDT) appears to be a sensitive and powerful tool to objectively and rapidly screen for cognitive impairment and predict at-fault collision involvement. The ACDT, a multimedia and interactive product (Times2Tell TM), is commercially available through SpecialtyAutomated Systems Corp. (Boca Raton, FL) at www.specialtyautomated.com. It provides automatic scoring and feedback. It eliminates the need for specifications in administration and scoring that the CDT requires.
