Thyroid Hormone Levels Linked to Brain Region Volumes Critical for Memory
Association of hippocampus, entorhinal cortex, and amygdala with thyroid function: a bilateral volumetric analysis.
Background
The thyroid gland produces hormones essential for metabolism, growth, and neurological development. Dysregulation of thyroid function, such as hypothyroidism (underactive thyroid) or hyperthyroidism (overactive thyroid), is known to impact cognitive function and mood. While the general link between thyroid health and brain function is established, the specific volumetric changes in key brain regions like the hippocampus, entorhinal cortex, and amygdala in relation to varying thyroid hormone levels remain less precisely quantified.
