However, up to 15% of patients may also present psychotic symptoms, which represents a relatively rare and poorly understood manifestation. Existing literature on this condition consists primarily of isolated case reports, which describe short courses of antipsychotic treatment. In contrast, the present case illustrates a prolonged and more complex trajectory, contributing to a better understanding of the psychiatric presentations of hypothyroidism and their management.</p> <p><bold>CASE PRESENTATION:</bold> We report the case of a 42-year-old man hospitalized for violent behavior toward others and overt psychotic symptoms in untreated hypothyroidism. Tests revealed elevated thyroid-stimulating hormone levels of 34.925 mIU/L. Clinical evaluation confirmed significant psychiatric disturbance necessitating inpatient care. A diagnosis of secondary psychotic disorder due to hypothyroidism was established. The patient required prolonged antipsychotic treatment, and an initial attempt to discontinue treatment was unsuccessful. A second withdrawal attempt made several months later was successful, with full recovery and complete remission of symptoms. This remission was maintained despite recurrent thyroid-stimulating hormone level elevation, while thyroxine hormone levels remained within the normal range.</p> <p><bold>CONCLUSION:</bold> This case illustrates the importance of ruling out non-psychiatric medical causes in the differential diagnosis of psychiatric symptoms. It also highlights the need for individualized treatment plans and sustained follow-up, particularly in rare and poorly understood conditions for which no formal guidelines or standardized management protocols exist.</p></abstract><trans-abstract xml:lang="ru"><p><bold>ВВЕДЕНИЕ:</bold> Гипотиреоз — распространенное заболевание щитовидной железы, часто сопровождающееся аффективными и когнитивными нарушениями. Однако примерно у 15% пациентов заболевание может также проявляться психотическими симптомами. Это относительно редкое и малоизученное проявление гипотиреоза. На данный момент публикации, посвященные данному феномену, ограничиваются описанием отдельных клинических случаев, в которых преимущественно рассматривается краткосрочное применение антипсихотических препаратов. В отличие от ранее опубликованных, представленный случай демонстрирует более продолжительный и сложный клинический сценарий, что позволяет глубже изучить психические проявления гипотиреоза и оптимизировать подходы к терапии.</p> <p><bold>ОПИСАНИЕ КЛИНИЧЕСКОГО СЛУЧАЯ:</bold> Авторы описывают случай 42-летнего пациента, госпитализированного с гетероагрессией и выраженными психотическими симптомами, которые развились на фоне нелеченого гипотиреоза с повышенным уровнем тиреотропного гормона (ТТГ) (34,925 мМЕ/л). Клиническое обследование подтвердило наличие серьезного психического расстройства, потребовавшего госпитализации. Пациенту был диагностирован вторичный психотический синдром на фоне гипотиреоза. Потребовалась длительная терапия антипсихотиками, при этом первая попытка отмены препаратов сопровождалась ребаунд-эффектом. Однако повторная попытка отмены, предпринятая спустя несколько месяцев, привела к полному восстановлению и стойкой ремиссии симптомов, даже несмотря на рецидивирующее повышение уровня ТТГ при стабильно нормальном уровне тироксина.</p> <p><bold>ЗАКЛЮЧЕНИЕ:</bold> Настоящий клинический случай указывает на важность исключения соматических причин при дифференциальной диагностике психических расстройств. Он подчеркивает необходимость длительного клинического наблюдения и индивидуализированного подхода к терапии, особенно при редких и малоизученных патологиях, в отношении которых отсутствуют официальные клинические рекомендации или стандартизированные протоколы лечения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>hypothyroidism</kwd><kwd>hallucinations</kwd><kwd>delusions</kwd><kwd>depression</kwd><kwd>case report</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гипотиреоз</kwd><kwd>галлюцинации</kwd><kwd>бред</kwd><kwd>депрессия</kwd><kwd>клинический случай</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Taylor PN, Albrecht D, Scholz A, et al.
