Introduction. The Five-Minute Cognitive Test is designed to detect impairments in five areas of cognitive functions, including episodic memory, fluency of speech, time orientation, visual-spatial perception and executive functions.

Aim. The effectiveness of the Five-Minute Cognitive Test for assessing cognitive impairment compared with the MMSE short mental status assessment scale has been investigated. The relationship between the indicators of the Five-Minute Cognitive Test and the Short Scale for Assessing Mental Status with the volume of the hippocampus of the subjects was studied.

Materials and methods. The final version of the five-minute cognitive test is a test for evaluating five cognitive functions, including episodic memory (8 images for visual memorization), fluency of speech, time orientation, visual-spatial perception and executive functions.

Results. The effectiveness of the Five-Minute Cognitive Test as a diagnostic screening is higher than that of the Mini-Mental State Examination in the same cohort of patients, and it takes an average of 5-6 minutes to perform the test. The sensitivity and specificity of the five-minute cognitive test for screening cognitive impairment is 80.6 and 84.11 %, respectively; the results of the Five-Minute Cognitive Test positively correlate with the volumes of the hippocampus of the subjects.

Discussion. The comparability of specificity indicators and clinical and neuroimaging correlations with greater sensitivity of PCT in patients with moderate and mild demental cognitive impairment dictates the need for its wider use in clinical trials and routine practice.

Conclusion. The Five-Minute Cognitive Test is a new, relevant screening test for detecting cognitive impairments of varying severity, including the early stages of dementia disorders.
