How can the DiCoDi ® (Digital Cognitive Diagnostics) be used as a cognitive test in everyday practice?

Hearing loss can be a potential risk factor for later dementia. At the same time, existing cognitive tests are mostly auditory-based and rely on intact sensory function, which limits their ability to accurately assess cognitive performance in individuals with hearing loss. Against this background, the Digital Cognitive Diagnostics (DiCoDi®) test was developed. DiCoDi® was evaluated for validity and reliability in 200 control participants and 173 individuals with hearing loss. Additionally, a comprehensive neuropsychological test battery was administered. As expected, all DiCoDi® subtests correlated significantly with their corresponding paper-and-pencil equivalents (p<0.001), while showing no significant association with a depression questionnaire (p>0.05). The test also demonstrated high test-retest reliability (p<0.0005). Accordingly, DiCoDi® is a valid and reliable tool for the early detection of cognitive deficits. It can be used alongside standard audiological diagnostics in ENT clinics and hearing aid centers, as well as by neurologists, neuropsychologists, and memory clinics.
