Background. Post-COVID syndrome is often accompanied by persistent cognitive impairments that reduce patients’ functional capacity and quality of life and require effective rehabilitation approaches. Neurorehabilitation programmes remain insufficiently standardised, which necessitates an assessment of their clinical effectiveness.
Aim. To investigate the effectiveness of neurorehabilitation programmes for patients with post-COVID cognitive dysfunction in terms of restoring cognitive function.
Research Ethics. The study was conducted in accordance with the World Medical Association Declaration of Helsinki (1964–2024) and approved by the Ethics Committee of the Kharkiv Institute of Medicine and Biomedical Sciences (Protocol No.33 of October 03, 2024). All participants provided informed consent to participate in the study, and the data obtained were anonymised to ensure confidentiality.
Materials and Methods. For the analysis of cognitive recovery dynamics, 71 participants who completed the rehabilitation course were included. Assessment was performed using the TAP (Test for Attentional Performance) upon admission and after treatment. The FSMC (Fatigue Scale for Motor and Cognitive Functions) and the MoCA (Montreal Cognitive Assessment) were also used to determine the level of general and cognitive fatigue and the presence of cognitive deficit. Statistical analysis was performed using descriptive and inferential statistics. Calculations were carried out using Excel 365 (Microsoft, USA). The research was conducted as a private initiative of the authors, without grant support and state registration of the topic.
Results. The mean age of the participants was 49.5 years (SD (Standard Deviation) =10.10), and 70.4% (50 out of 71) were women. The mean time since initial COVID-19 infection was 29 months (SD=8.11). It was found that 27.0% of patients had cognitive deficit (MoCA<26), which was significantly lower compared to participants who dropped out (38.0%, p<0.001). After rehabilitation, improvements were observed in all TAP subscales: pathological reaction times in the alertness subtest decreased from 70.4% to 50.7%, sustained attention from 54.9% to 42.3%, working memory from 26.8% to 19.7%, and divided attention from 32.4% to 25.4%. The changes were statistically significant (p<0.05).
Conclusions. The data confirm the feasibility of using standardised cognitive tests (TAP, MoCA, FSMC) in clinical practice to monitor the dynamics of cognitive recovery after COVID-19.
Keywords: neurology, physical therapy and rehabilitation, neurotransmitter system, concentration of attention, cognitive deficit, neuromodulation.
