Can brain stimulation treat long COVID ‘brain fog’?

Speaking to Medical News Today, Keiland Cooper, Ph.D(c), a neuroscientist at the University of California, Irvine who was not involved in the study, explained, “While evidence of COVID-19 entering the brain is lacking, mounting evidence suggests that a vascular deficit may underlie many of the cognitive long COVID-19 symptoms.” … He cautioned, “[T]he small sample size limits the amount of conclusions to be made, however, and future work, such as controlled trials, will be needed to assess the efficacy and safety of stimulation as a possible method to mitigate symptoms.”
