![]() ![]() Cooper commented further that “n the present paper, the authors’ attempt to mitigate this deficit via brain stimulation is an interesting one.” He went on to suggest the mechanism behind this “may be due to disruption of the target receptor of the virus, ACE2, which is involved in blood pressure regulation.”ĭr. 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.” This was due to increased blood flow, which resulted from restored blood vessel regulation. The authors concluded that NIBS improved cognitive and visual complications as a result of reoxygenation of the silent neurons. The blood delivers oxygen and nutrients, reactivating the hibernating or silenced neurons and allowing cognitive and vision recovery. Repeated stimulation with electrical current helps the muscles of the vessel walls to relax, which lets the blood flow more freely to the cells. The cells are too healthy to die but cannot fire signals, so they enter a “hibernation” mode. Reduced oxygen slows cell metabolism and stops them from functioning. This reduces the blood flow and deprives the neurons of oxygen. ![]() The research team believed that vessels affected by COVID-19 in the brain fail to dilate due to swelling in the vessel wall. Both of these improved after treatment, with one participant also showing a positive 40–60% recovery in the cognitive tests. The researchers noted improved blood vessel regulation in peripheral arteries and veins, with “all veins” showing an improved maximum vessel dilation of 113% and peripheral veins showing an average 300% change in vessel dilation after NIBS treatment.Īs well as vision problems, the participants had reported serious cognitive defects. The study found that noninvasive neuromodulation using NIBS improved visual field loss in under 4 days. After treatment, the participants rested for 15 minutes. The researchers briefly delivered electric currents through electrodes attached to the forehead while participants were sitting. Participants received 10–13 therapy sessions lasting 30–45 minutes each. Researchers delivered alternating current stimulation of the eyes and brain and completed cognitive assessments before and after treatment. Researchers at the SAVIR-Center in Magdeburg, Germany, treated two females with long COVID symptoms using noninvasive brain stimulation (NIBS) to understand if neuromodulation could enhance blood flow and reverse visual impairment. They outline that hypoxia, or lack of oxygen, reduces metabolic activity and silences the neurons, or the cells of the nervous system. The study authors suggest that changes in blood vessel health, specifically small microvessels, reduced blood flow, and lack of oxygen are the main cause of central nervous system symptoms in people with COVID-19. Now, a recent study published in Restorative Neurology and Neuroscience has found that increasing blood flow using microcurrents may be an effective way to treat symptoms of cognitive impairment, vision loss, and fatigue in people with long COVID. cognitive impairment and brain fog, or difficulty thinking and concentrating.breathlessness and breathing difficulties.The most commonly described symptoms include: The severity of the initial COVID-19 illness has little impact on the risk of having long COVID - even people with mild cases of illness can have symptoms of long COVID.
