Old people often present a chronic depletion in zinc. Any stress increases zinc consumption and zinc loss through the kidneys; acute depletion then appears. Anorexia is usual, psycho-neurological troubles induce to a wrong diagnostic of sudden senility or psychiatric disorder. Altered taste and a low blood level of zinc confirms the diagnostic. Zinc administration, usually per os, leads to a prompt recovery. 18 patients have been recorded; acute depletion occurred after infection or any ordinary surgical intervention.
老年人常常存在锌慢性缺乏的情况。任何应激都会增加锌的消耗以及通过肾脏的锌流失；进而出现急性缺乏。通常会有食欲不振，神经精神方面的问题会导致误诊为突发性衰老或精神疾病。味觉改变和低血锌水平可确诊。通常经口给予锌剂后，症状会迅速缓解。已记录18例患者；急性缺乏发生在感染或任何普通外科手术后。
