BetterHealth reduces side effects and increases treatment effectiveness through personalization of medication type and dosage, by allowing patients and doctors to make data-driven decisions. We focus on Attention Deficit Hyperactivity Disorder (ADHD) and Attention Deficit Disorder (ADD) patients, mainly youth and children, because treatment with these medications can include significant side effects with varying impact. We aim to optimize patients’ treatment through a platform (app) that assists patients in tracking their medication dosage, health condition and side effects on a regular basis, and sharing this information automatically with their doctor.
