This is a remarkable story, atleast for me. It highlights the importance to find patterns in data and then map those patterns to something X. Agreed it takes time to do this and is exhausting as well but results are far more amazing.

Same thing happened with recent tremors related non-invasive surgery at Imperial college London. Data played extremely crucial part to localize it. (http://www.bbc.com/news/health-38157770)

Really excited to envision a purely data-driven healthcare system. It will have a significant impact on our understanding of different diseases.

Anyone knows where to find such anonymous health/disease related data for further research?
