Photobiomodulation in the prevention and treatment of neurological symptoms resulting from COVID-19: Perspectives from the scientific literature
INTRODUCTION: During COVID-19 pandemic, many questions are asked, but few have answers. Doctors and researchers say that the virus causes an overreaction of the immune system known as a "cytokine storm". The high tropism of the virus by the respiratory system is known, but neurological symptoms are also reported in infected patients. Cerebral photobiomodulation using red and infrared light is an innovative therapy for the treatment of neurological conditions. AIM: To gather information from scientific databases and analyze whether photobiomodulation can be used as a tool for the prevention and treatment of neurological symptoms resulting from COVID-19 infection. MATERIAL AND METHODS: Bibliographic search in PubMED, Web of Knowledge, Virtual Health Library (includes MEDLINE and LILACS) and SciELO, using the descriptors: "Photobiomodulation", "COVID-19", "neurological damage", "neurological disease", "neurological impacts "and" Neurological effects ". Articles were selected including from original research to letters for editorial. RESULTS: In all, 35 searches were performed using the combination of descriptors and data platforms. The authors identified 10 articles that met the search criteria. All articles were found on PubMED. The other platforms did not present publications. It was found in isolation on: applicability of photobiomodulation to prevent and repair neurological damage and; how the coronavirus family can show tropism for the nervous system and trigger damage. However, none of the articles have a direct relationship between photobiomodulation and the treatment or prevention of neurological symptoms resulting from COVID-19 infection. CONCLUSION: Photobiomodulation has been identified as a possible therapy for the prevention and treatment of patients with COVID-19. In parallel, research shows how this therapy can be used in neurological changes, making it promising in the treatment of damage caused by the new virus. Specific studies need to be directed to this area, considering the potential of laser therapy in neurological disorders.
