Regardless of its role in memory, vitamin B-12 remains an important part of a healthy diet.

Can hypothyroidism cause brain damage?

Thyroid hormone deficiency during critical transition periods may lead to irreversible brain damage, the consequences of which depend on the severity and duration of the deficiency, and most importantly its time of onset (10-14).

Is Vitamin D good for thyroid?

Does levothyroxine cause memory loss?

When assessing the effects of 3-month treatment, results revealed that the treated hypothyroid group had significant increased verbal memory retrieval. Results suggest that specific memory retrieval deficits associated with hypothyroidism can resolve after replacement therapy with levothyroxine.

Does hyperthyroidism affect memory?

Thyroid hormone has important effects on brain/cognitive functioning. Severe thyroid disease, either hyperthyroidism or hypothyroidism, is associated with cognitive deficits such as memory loss, difficulty concentrating and “brain fog”. In the elderly, these deficits could be misdiagnosed as dementia.
