COVID-19 is a respiratory illness that is spread mostly through respiratory droplets. COVID-19 infection can cause mild to severe symptoms, including severe respiratory symptoms (bilateral severe pneumonia), septic shock, and death. Neurological and psychiatric symptoms, such as headache, paraesthesia, myalgia, decreased consciousness, disorientation or psychosis, and cerebrovascular illnesses, are frequently brought on by the virus's entry into the brain. SARS-CoV-2-positive individuals should be assessed for neurological and psychiatric symptoms as soon as possible since treatment of infection-related neurological and psychiatric consequences is critical to improving the prognosis of severe COVID-19 patients. Currently, it appears that in COVID-19 survivors, the inflammatory systemic process and/or the inflammatory process of the brain may initiate long-term pathways that can increase neurological and neurodegenerative problems in the future years and decades. Negative psychosocial outcomes, such as depression symptoms, anxiety, stress, anger, sleep disturbances, signs of PTSD, social isolation, loneliness, and stigmatisation, are linked to the COVID-19 pandemic.
