Artificial intelligence (AI) is a field of computer science concerned with the simulation of human intelligence by smart machines and computational rationality. AI is about to transform medical practice. With the help of this technology, a doctor can examine and treat the patient without visiting any hospital or clinic. Thus, this technology is now accessible to provide online services to patients. Any patient complaints may be rapidly addressed with various health issues. AI has been studied in several fields of medical practice and health science, including population health, precision medicine, and natural language treatment. Our objective is to review the applications of AI in the field of health science research. In this research, how AI helps solving the difficult medical problems through extensive research and development is demonstrated
