How does hypothyroidism affect memory loss?
Severe hypothyroidism can induce temporary memory loss. However, only in the congenital form of the disease is the memory loss permanent. In hypothyroidism occurring even in childhood, and certainly in adult life, any memory loss related to hypothyroidism is completely returned to normal when the patient is treated with thyroxine. As long as they take sufficient thyroxine to maintain them in a normal state, all functions related to thyroid activity are also normal.
