The Claim

In individuals with Down syndrome and autoimmune thyroid disease, thyroid function exhibits fluctuations between hyperthyroidism and hypothyroidism over years, even after discontinuation of antithyroid medication, resulting in a highly unstable clinical course that complicates treatment decisions.

Description
1 study reviewed
In plain English

People with Down syndrome and autoimmune thyroid disease experience repeated shifts between overactive and underactive thyroid states over many years, even after stopping thyroid medication, making their condition difficult to manage.

See the scientific wording

In individuals with Down syndrome and autoimmune thyroid disease, thyroid function can fluctuate between hyperthyroidism and hypothyroidism over years, even after discontinuation of antithyroid medication, indicating a highly unstable clinical course that complicates treatment decisions.

Why this might work

Antibodies in the blood alternately trick the thyroid into making too much hormone or block it from making any, while ongoing inflammation slowly destroys the thyroid's ability to respond to signals, causing hormone levels to swing wildly between too high and too low.

  1. Study: Discordance Between Thyroid Function and Thyroid-Stimulating Hormone (TSH) Receptor Antibodies in Down Syndrome Patients With Autoimmune Thyroid Disease: A Long-Term Follow-Up Study of Two Cases

    In two people with Down syndrome and thyroid problems, their thyroid hormone levels kept switching between too high and too low, even after they stopped taking medicine — making it really hard for doctors to know how to treat them. This shows the claim is true.
