Fact Check: What’s the real scoop on Hillary Clinton’s health? [...] In December 2012, Clinton was diagnosed with a concussion, which caused double vision for nearly two months. But Bardack - director of internal medicine, Mount Sinai Health System at CareMount Medical - said that follow-up medical exams in 2013 “revealed complete resolution of the effects of the concussion.”

Bardack’s letter said, “During follow up evaluations, Mrs. Clinton was found to have a transverse sinus venous thrombosis and began anticoagulation therapy to dissolve the clot. As a result of the concussion, Mrs. Clinton also experienced double vision for a period of time and benefited from wearing glasses with a Fresnel Prism.”
At the time, Bardack said Clinton’s most recent physical examination on March 21, 2015, “revealed a healthy-appearing female” who follows a healthy diet and exercises regularly, including yoga, swimming, walking and weight training.
