Overactive Thyroid Increases Stroke Risk in Young Adults

By , About.com GuideApril 1, 2010

Follow me on:

A study conducted in Taiwan, and reported on in the journal Stroke: Journal of the American Heart Association, indicated that people under 45 with hyperthyroidism have a 44 percent higher risk of ischemic stroke than those with normal thyroid function. (An ischemic stroke is a blockage of blood flow to the brain that causes the death of brain cells.)

"Strokes of undetermined cause account for between one-third and one-fourth of all ischemic strokes in young people," said Herng-Ching Lin, Ph.D., senior author of the study and professor at the School of Health Care Administration, College of Medicine, Taipei Medical University in Taipei, Taiwan. "To the best of our knowledge, hyperthyroidism has never been considered as a potential risk factor for stroke in the 18 to 44 age group."

"Our study shows an association between hyperthyroidism and the risk of subsequent ischemic stroke in young adults," Lin said. "A more thorough evaluation in future studies may help elucidate the causes of stroke in this age group. Our results indicate a need for thyroid function testing and detection of hyperthyroidism in surveys to identify the causes of ischemic stroke in young people."

This article was quite unsatisfying. The researchers did not say which criteria they used to identify hyperthyroidism. I hope it was not just TSH.

I had a stroke when I was 42. No contributing factors were identified. I was slim, athletic, active, very good blood pressure, very good cholesterol levels, vert good diet. I was taking a dessicated thyroid medication at the time, and had been for many years. The Chief of Neurology at the big teaching hospital where I was treated said if he looked at all my tests, and took into account my general appearance, lifestyle etc. he would have assessed my probability of having a stroke as negligible. Yet I did have a stroke and as he called it “a pretty good bang” In light of that, he was amazed that I had no loss of speech or paralysis. I did and do have some short-term memory loss though, and often an inability to remember what I’ve just read. Fast forward a few years and in learning to read my own T levels, I believe I was overmedicated for sure, although I felt fine. I also have Pernicious Anemia, but after examination into a possible correlation, it was deemed unimportant. One thing I’ve noticed, I have written lots in the past, and when I read what I wrote, I can’t believe I ever thought or read at that level. I sure can’t do that now. Just glad to be alive though, even though I’m not as sharp as I used to be. Noone else notices it though, or if they do, are too polite to say so.

At 48, I, too, look at things I wrote in graduate school when I was in my mid 30’s before being diagnosed with Graves Disease and can’t believe I functioned at that level and wrote at the level. I have, too, experienced memory loss and feel that radiation for Graves and subsequent poorly managed hypothyroid disorder “dumbed me down” and I don’t function at the same level, intellectually, that I used to. I don’t think that I could even manage the graduate school load were I to attempt at this point in my life. I have always wondered about the correlation between thyroid disorder, radiation, memory loss, and intellectual functioning loss.

Hi Jonas,

As my Own experience, you must keep consult with your doctor monthly to see the progress of your hyperthyroid because the dosage of the pill must to gradually decrease otherwise you will go for hypo and your weight will increase faster.
Just go to your doctor please don’t event take or not take the pill under your own assume, and ask your doctor what the reflect if you keep taken the medicine over then should be.

My eyes now getting normal with enough resting time and not push myself to do heavy activities
