Thyroid and Cognition

Meaning

Thyroid and Cognition describes the profound and essential relationship between the thyroid hormone axis and various domains of brain function, including memory, attention, executive function, and mood stability. Optimal levels of thyroid hormones, specifically the active triiodothyronine (T3), are essential for normal neurodevelopment and for maintaining adult cognitive integrity throughout the lifespan. Both hypothyroidism and hyperthyroidism can lead to measurable cognitive impairment and neuropsychiatric symptoms, highlighting the gland’s critical role in neuroendocrine regulation.
