PatientsLikeMe started with one patient, and one family's experience with a life-changing condition. When Stephen Heywood was diagnosed with ALS in 1998 at the age of 29, his brothers Jamie and Ben got to work, trying anything they could to slow Stephen's disease progression. They became citizen scientists, harnessing the power of any and all information they could find. It was a trial-and-error approach. Something was missing and they knew there had to be a better way. What couldn't they find? The aggregated real-world experiences of others living with and fighting to survive ALS. So, they launched PatientsLikeMe (PLM) to connect ALS patients in 2005. It quickly expanded, and since 2011, we have been welcoming people living with any health condition to connect with peers, learn together and take charge of their health. Today, PatientsLikeMe is one of the world’s largest patient community and digital health management platforms. Its growing community of more than 850,000 members with over 2,800 conditions share personal stories and information about their health, symptoms, and treatments, with a goal to improve the lives of all patients through knowledge derived from shared real-world experiences and outcomes. PatientsLikeMe is a digital health platform uniquely designed to empower the patient communities with personal agency, establishing PatientsLikeMe as a clinically robust resource with demonstrated impact, validated by more than 100 studies in peer-reviewed medical and scientific journals. Under the leadership of Dr. Atul Dhir, PatientsLikeMe will accelerate its ambitious vision of evolving its trusted patient community into an industry leading consumer platform that helps patients navigate their health journey through peer learning and support, personalized health insights, tailored digital health services and patient-friendly clinical education.
