I am an MIT alum, and I suffer from POTS (postural orthostatic tachycardia syndrome). Before reading about the tragic news of MIT student Christina E. Tournant’s death, most of you had probably never heard of POTS. Most of the doctors that I have seen have also never heard of POTS. However, more people have POTS than multiple sclerosis (MS) or amyotrophic lateral sclerosis (ALS). Experts estimate that POTS impacts one to three million Americans, 85 percent of whom are female.
