Does hypothyroidism treatment cause memory loss?

Hello doctor! I was diagnosed with hypothyroidism a month ago and am taking medication. However, recently I have been forgetful and have been working inefficiently. Does hypothyroidism cause memory loss, doctor? I am only 34 years old so I am quite worried!

Doctor replied:

Hello!

Among the common symptoms of hypothyroidism, memory loss, decreased ability to concentrate, and poor work performance are possible manifestations, especially when the disease has not been treated stably.

However, if you have been treated for hypothyroidism for 1 month and your thyroid function has reached the control target, symptoms such as forgetfulness and poor work performance may no longer be directly related to hypothyroidism.

In this case, you should see a doctor again for a comprehensive assessment, to find other causes that may affect your memory and work efficiency, and from there, have timely and appropriate intervention.

Friendly!
