What Researchers Did
Researchers conducted a qualitative systematic review to synthesize evidence on treatments for cognitive impairment following COVID-19, including 29 studies published up to December 2023.
What They Found
Out of 7790 screened articles, 29 studies were included, indicating that multidisciplinary approaches, particularly those combining cognitive remediation, physical exercise, and dietary and sleep support, may improve post-COVID cognitive impairment. Cognitive remediation interventions were found to be a safe and cost-effective option, while noninvasive brain stimulation and hyperbaric oxygen therapy showed mixed or preliminary results.
Canadian Relevance
This systematic review did not include any specific Canadian studies or data, therefore direct Canadian relevance is not explicitly established.
Study Limitations
Limitations included significant heterogeneity across study designs, assessment tools, and recruitment criteria, making interpretation of the existing evidence challenging.
