Early diagnosis of cognitive impairment is one of the pressing challenges facing modern neurology and neuropsychology. Screening tools such as the Montreal Cognitive Assessment (MoCA) are widely used in clinical practice and are characterized by high sensitivity for detecting mild cognitive impairment. At the same time, the development of digital technologies provides new opportunities for a more detailed assessment of patients’ cognitive profiles.
The aim of this study was to evaluate the capabilities of the digital cognitive assessment battery CogniFit General Cognitive Assessment test and to determine its potential as a complementary tool to MoCA in cognitive function screening.
The study included 50 apparently healthy volunteers who had no subjective complaints of cognitive impairment. All participants underwent testing using MoCA and the digital cognitive battery CAB. The CAB battery includes a series of interactive tasks designed to assess various cognitive domains, including attention, memory, executive functions, processing speed, visuospatial abilities, reaction, and coordination. The average test completion time was approximately 30 minutes.
The mean MoCA score was 27.6 ± 1.2 points, which corresponded to normal values in most study participants. However, analysis of the CAB results revealed variability in individual cognitive function indicators. Most participants demonstrated relatively lower attention scores, primarily in the domains of focused and sustained attention. Another group of participants showed lower memory scores, mainly in working and short-term memory.
The obtained data indicate that CAB is capable of identifying individual characteristics of cognitive profiles even in the absence of clinically significant cognitive impairment. Thus, the digital battery CAB may be considered a promising tool for the screening and monitoring of cognitive functions and may be used as an adjunct to MoCA in clinical practice.
