Hillary ClintonHillary Rodham ClintonDems fear divisions will persist after DNC chair election Sanders and Schumer are right: Ellison for DNC chair Poll: Hackers say it takes less than 12 hours to breach systems MORE said she continues to take blood thinners after doctors found a blood clot between her brain and skull in 2012.
However, she told People magazine she has no lingering effects of a concussion that she suffered shortly before the clot was discovered.
"I did have a concussion and some effects in the aftermath of it, mostly dizziness, double vision,” she said. “Those all dissipated. Blood thinners are my continuing treatment for the blood clot.”
Her doctors previously announced she was taking the medication in early 2013.
Because of the injury, Clinton said she was not able to do everything she wanted before she left the State Department in 2013. However, she did get to testify before Congress about the events surrounding the 2012 terrorist attack in Benghazi, Libya, that killed four Americans.
"But I was determined to do as much as I could, and that included testifying before Congress,” she said. “I was able to do that, which was the most important thing to me."
As Clinton contemplates a run for president in 2016, some have sought to make her health an issue.
In March, Karl Rove said, “Thirty days in the hospital? And when she reappears, she’s wearing glasses that are only for people who have traumatic brain injury? We need to know what’s up with that.”
Clinton said she bonded with Rep. Paul Ryan (R-Wis.), the former GOP nominee for vice president, about her injury. During a conversation at President Obama’s inauguration, Ryan revealed he had three previous concussions, she said.
Clinton remembered: “He said, 'One was really serious. I'm so grateful to my mother, because she said, 'You're grounded. You're going to rest until it goes away.' "
A Ryan spokesman confirmed the conversation to The Associated Press but said the congressman has only had two concussions.
Clinton said concussions have not been taken seriously until recently, and she is conscious that others do not always get the care they need.
"People have basically been told to shake it off," she said. "I could've shaken it off. But at what cost? I rested and went back to work after the first of the year."
