Conclusions
The impact of the interaction between the brain and the heart cannot be ignored. Considering that the human body is a complex integrated system, the treatment of COVID-19 patients with neurological or psychiatric symptoms requires taking into account the risk of heart damage. Although the specific mechanism by which COVID-19 affects the brain and the heart remains unknown, its combined effects on both organs may aggravate the condition of COVID-19 patients. Therefore, it is critical to monitor cardiac function in COVID-19 patients developing neurological and mental disorders. It is imperative that neurologists, psychologists, and cardiologists work together on patient care. A collaborative effort can delay further development of the disease, improve the recovery rate, and reduce mortality.
