Doctors around the world are not only treating the COVID-19 affected patients but also involved in treating post recovery symptoms. Doctors are involved in treating the mysterious ‘brain fog’ experienced by few people who has recovered from Covid-19. Short-term memory loss, trouble concentrating and focusing on tasks they normally do with ease, dizziness and confusion are exhibited by the patients.  Few other Patients also suffer from neurological symptoms such as Guillain-Barre Syndrome (GBS), a condition under which body’s immune system attacks the peripheral nervous system.

Covid-19 leaves long lasting impact on health

Dr T R Hemkumar, consultant of internal medicine at Sakra World Hospital said, two male patients in their 40s, senior executives was discharged from the hospital in August after they recovered from corona virus. In the late september, they were reported of memory loss who were completely active earlier. They were unable to read and write easily, focus on work, read newspapers, do puzzles or work as they did before corona infection. Memory loss if occurs is not quantifiable as mild, moderate or severe. Few other hospitals have seen patients after recovery with complaints of memory loss, fatigue, dizziness, confusion, excess sleepiness and GBS, which causes sudden weakness in the limbs, leading to inability to walk and stumbling while walking, which can last for weeks. In a instance, people gts confused with day and Night, forget peoples name, forget their day to day activities. 

62 lakh people recover from Corona, active case remains below 9 lakh

Though various cases have been reported around the world there is no research or study to point out the cause. Dr. Hemkumar made a guess that it maight be due to encephalopathy, a disease of the brain (caused by bacteria or virus) that alters its structure or function. One more is  encephalitis (inflammation of the brain) seen in high-risk patients admitted in the ICU. It might be mild at the time of infection and increased after recovery. Low Oxygen levels in brain, hypoxia might also be a cause. Doctors say the duration of the existence is not known yet, it is new to the world.
