Low doses of lithium, as might be used for mood or dementia prevention, do not carry the same renal, toxicity, and tolerability problems of doses used for prophylaxis or treatment of mania. However, thyroid effects of low doses have not been investigated. Our goal in this study was to assess the changes in thyroid-stimulating hormone (TSH) associated with a broad range of lithium levels, including those well below the therapeutic range for bipolar disorders.

低和极低的锂含量：对甲状腺的影响很小，但仍需要监测

低剂量的锂可用于预防情绪或痴呆，但不会带来与用于预防或治疗躁狂症的剂量相同的肾脏、毒性和耐受性问题。然而，低剂量对甲状腺的影响尚未得到研究。我们在这项研究中的目标是评估与各种锂水平相关的促甲状腺激素（TSH）的变化，包括远低于双相情感障碍治疗范围的锂水平。
