Thyroid Problems Linked to Increased Risk of Dementia

Older people with hypothyroidism, also called underactive thyroid, may be at increased risk of developing dementia, according to a study published in the July 6, 2022, online issue of Neurology^®, the medical journal of the American Academy of Neurology. The risk of developing dementia was even higher for people whose thyroid condition required thyroid hormone replacement medication.

Hypothyroidism occurs when the thyroid gland doesn’t make enough thyroid hormones. This can slow metabolism. Symptoms include feeling tired, weight gain and sensitivity to cold.
