Precision medicine is a new buzzword in the field of medicine. This technique refers to providing personalized treatment to each patient while keeping in view the individual risk factors such as variation in genes, lifestyle, and environment. Because the machine learning can process large amounts of historical data at a much faster pace than humans, therefore some experts are of the view that precision medicine is not possible without integrating machine learning algorithms in the whole process. One of the major benefits of precision medicine is that it can forecast if the person can catch a certain disease in the future or not. Thus, it leverages the medical professionals to comprehend the conditions in which the disease may progress. With the integration of AI, the medical professionals can predict the disease of the patient more accurately, develop new drugs, and suggest individualized treatments to the patients.

Building New Tools Using Crowdsourced Data

Crowdsourcing permits the medical researchers to have access to the huge amount of medical data, which people upload willingly. This live health information will transform the way the healthcare industry will operate in the future. The progress in artificial intelligence and machine learning is creating new opportunities to use this real-time data for enhancing the treatment of certain diseases. Take an example of an Apple Research Kit that gives users access to ML-driven facial recognition applications for the treatment of Asperger’s and Parkinson’s diseases. IBM and Metatron have collaborated recently to create a tool that would comprehend, gather, and share insulin and diabetes data of the people in real-time based on crowdsourced data.

Discovering Drugs for the Existing and New Diseases

It sometimes takes more than a decade to develop a drug through clinical trials. Therefore, the pharmaceutical industry was always looking for a way that could lead to the faster discovery to save the lives of millions of people. AI tools are helping biotechnology and pharmaceutical companies in restructuring their research and development processes.
