Vitamin B12 deficiency can manifest with haematological, gastrointestinal and neuropsychiatric signs. The neuropsychiatric symptoms may be concurrent or precede the other symptoms. The reported case is a clinical case of delirium due to vitamin B12 deficiency in a female vegetarian patient. The patient was treated with vitamin B12 supplementation. Initially, it was difficult to diagnose this patient, who presented with delirium that could have been due to multiple causes. The finding underlines the importance of conducting a complete laboratory test panel for delirium, including the blood levels of vitamin B12.
维生素 B12 缺乏可表现为血液学、胃肠道和神经精神症状。神经精神症状可能与其他症状同时或先于其他症状出现。本报告病例为一名女性素食患者因维生素 B12 缺乏导致的谵妄临床病例。该患者接受了维生素 B12 补充治疗。最初，该患者的诊断较为困难，因为她出现的谵妄可能由多种原因引起。这一发现强调了对谵妄进行全面实验室检查的重要性，包括血液中维生素 B12 的水平。
