J Alzheimer's Dis: Harvard University authority expert: COVID-19 can damage the nervous system, causing varying degrees of brain damage

Introduction: It is well known thatCOVID-19mainly harms the respiratory tract of patients and causes serious damage to the respiratory systemBut recently, Harvard University neurology experts said that COVID-19 will not only damage the body's respiratory system, but also damage the body's nervous system, resulting in varying degrees of brain damage, researchers reviewed the effects of COVID-19 on the nervous system in a paper published in the Journal of Alzheimer's Disease, which divided the brain damage caused by COVID-19 into three stagesDrMajid Fotuhi, medical director of the Northern Virginia Center for Neurogrowth Brain Health and a nationally recognized neurologist and co-author of the study, encouraged the use of a three-stage classification that called for more research on the long-term effects of COVID-19 on the brain and highlighted the need for patients to undergo an MRI examination of the brain before they are discharged"We have learned that a large number of patients with COVID-19 who were hospitalized had varying degrees of impaired brain function," MrFodusi saidAs part of the medical community, we need to monitor these patients over the long term, as some of them may experience cognitive decline, attention deficit, brain fog, or Alzheimer's disease in the futureThere are many things we can do to promote brain recovery in PATIENTs with COVID-19But first we must understand the nature and severity of neurological dysfunctionAt the patient level, a baseline MRI prior to discharge is necessary so that we have a starting point for evaluation and treatmentSARS-Cov2: Cell mechanismSARS-Cov2 binds ACE2 intoblood vessels epithelial cells and cells of multiple other organs in a recent article published , Fordusi and his colleagues warned that neurological problems in patients with COVID-19 include stroke, epilepsy
, confusion, dizziness, paralysis and coma Twenty-four cases have been reported to reveal the effects of COVID-19 on the brain of patients In fact, a study from Wuhan, China, showed that 45% of patients with severe COVID-19 had significant neurological impairments Another study from France showed that 84 per cent of patients in intensive care unit (ICU) COVID-19 tested positive for neurological abnormalities, and 15 per cent of patients who left the ICU still had "execution dysfunction", including lack of concentration, decision-making and behavioural control the paper proposes the use of a three-stage classification system of "neuro-coronavirus" to provide a basis for the future establishment of sars-CoV-2 and nervous system hypothesis and investigation These stages include: neuro-coronavirus phase I: virus damage is limited to the upper skin cells of the mouth and nose, the main symptoms are transient loss of smell and taste Neuro-coronavirus PHASE II: The virus causes inflammation, becomes a cytokine storm, starting in the lungs, and spreading through blood vessels through the body so organs This cytokine storm causes blood clots to form, leading to strokes large and small in the brain Neuroguanic Virus Phase III: Explosive levels of cytokine storms destroy the blood-brain barrier (protective insulation in the blood vessels of the brain) As a result, blood levels, inflammatory markers and viral particles invade the brain, causing epilepsy, confusion, coma, or encephalopathy , Said that many patients with COVID-19 may initially have no obvious neurological symptoms, but in some cases, patients may develop neurological symptoms between fever, cough or shortness of breath In addition to an MRI test at the hospital, patients should be monitored for several months after hospitalization "Our study of coronaviruses shows that long-term patients may experience depression, insomnia, Parkinson's syndrome, memory loss, or accelerated aging of the brain," explains Fordusi For those who are recovering from COVID-19, I recommend regular exercise, eating a healthy heart-healthy diet, reducing stress, and improving sleep, all of which are key ways to rejuvenate the brain and reduce future adverse consequences these interventions, along with targeted brain training and neurofeedback therapy, are key features of Dr Fordusch's 12-week brain health plan The study, published in the Journal of The of Prevention of Alzheimer's disease, found that 84 percent of older adults with cognitive impairment who completed the brain rehabilitation program had improved brain function, many of whom had an increase in brain learning and memory The findings are similar to those in patients recovering from persistent post-concussion syndrome The project will now be tailored for patients with post-COVID-19 neurological problems Dr Fodusi is a neuroscientist and neuroscientist trained at Harvard University and Johns Hopkins University and is widely recognized as an authority in memory, Alzheimer's disease, concussion therapy, HYPERACTIVITy, and brain activity at any age
