What Researchers Did
Researchers conducted a systematic review of 17 studies to evaluate various intervention modalities for brain fog experienced by adults with long-COVID.
What They Found
Among the 17 studies, six on noninvasive brain stimulation consistently showed improved cognitive ability, and three on hyperbaric oxygen therapy demonstrated improvements in cognitive assessment tests and brain perfusion.
Additionally, two studies indicated that Palmitoylethanolamide and Luteolin (PEA-LUT) improved cognitive impairment.
What This Means for Canadian Patients
Canadian patients experiencing long-COVID brain fog may find potential relief through interventions like noninvasive brain stimulation or hyperbaric oxygen therapy, which showed promising results in this review.
Further research is needed, but these findings offer hope for managing debilitating cognitive symptoms.
Canadian Relevance
This systematic review did not include any studies with a specific Canadian connection.
Study Limitations
A limitation of this review is the diverse approaches and varied outcomes across the included rehabilitation studies, which may affect the generalizability of findings.
