In plain English

In older adults, thyroid stimulating hormone levels are not linked to cognitive function, even when people taking thyroid medication or antidepressants are removed from the analysis.

See the scientific wording

The absence of a significant association between thyroid stimulating hormone and cognitive function in older adults persists even after excluding individuals taking thyroid medication or antidepressants, suggesting these medications do not fully account for the null findings.

Why this might work

The brain's energy use and nerve cell activity stay steady even when thyroid hormone levels change, so thinking and memory skills do not change with thyroid hormone levels in older adults.

  1. Study: The Association of Thyroid Stimulating Hormone Levels with Cognitive Function and Depressed Mood

    Even when researchers removed people who were taking thyroid medicine, they still found no link between thyroid hormone levels and memory or thinking skills in older adults. This means the medicine isn’t hiding a real connection.
