В сером веществе мозга, там, где зарождается мысль, течение крови замедляется. В клетки мозга поступает меньше кислорода и питательных веществ. Мозг истощается, пациент начинает медленнее соображать и двигаться. Если бы возникла экстраординарная ситуация, при которой какой - то человек полностью утратил бы тиреоидные гормоны, то он лишился бы ума, памяти и даже эмоций. Без проведения соответствующего лечения недостаток тиреоидных гормонов - гипотиреоз - вызывает быстрое старение кровеносных сосудов мозга, их изменение в результате процесса, называемого атеросклерозом.


Кроме того, недостаток тиреоидных гормонов вызывает уменьшение количества связей (синапсов) между клетками мозга.<!--more--> Происходит ослабление этих очень важных клеток. При этом не только замедляются движения и мыслительный процесс, но нарушается память, человеку бывает трудно сконцентрироваться. Подобные симптомы отмечаются по утрам, при пробуждении или во время отдыха, когда человек перестает двигатьД ся. Таким образом, тиреоидные гормоны играют главную роль в сохранении хорошей памяти. Одна из целей тиреоидно - гормонально - замести тельной терапии - полностью или частично обратить вспятв преждевременное старение артерий и ускорить кровоток через мозг. При восполнении тиреоидного дефицита нейроны, не получавшие в достато ном объеме питательных веществ и кислорода, снова обеспечиваются необходимым питанием. Постепенно к ним возвращается мыслительная двигательная активность.
