近日，一则“小伙出差后突然失忆，竟被维生素B12治愈”的新闻引发关注。这名年轻男子在出差途中突发严重记忆障碍，甚至无法辨认家人，经医院详细检查后，确诊为维生素B12缺乏引起的神经系统病变。在补充维生素B12后，其记忆功能迅速恢复。维生素B12是维持神经系统健康的关键营养素，参与髓鞘合成，缺乏会导致神经传导障碍，可能引发记忆力下降、精神混乱甚至痴呆样症状。长期饮食不均衡、消化吸收功能差的人群易出现缺乏。该案例提醒公众：突然出现的认知异常不可忽视，需及时就医排查营养性或病理性原因。日常应注意膳食多样，适量摄入肉类、蛋奶等富含B12的食物，必要时遵医嘱补充。
A recent news story about a young man who suddenly lost his memory during a business trip and was cured by vitamin B12 has attracted widespread attention. The individual developed severe amnesia, even unable to recognize his family, and was diagnosed with neurological damage caused by vitamin B12 deficiency. After supplementation, his memory quickly recovered.Vitamin B12 is essential for nervous system health, playing a key role in myelin synthesis. Its deficiency can impair nerve signal transmission, leading to symptoms like memory loss, confusion, and even dementia-like conditions. People with long-term unbalanced diets or poor nutrient absorption are at higher risk. This case highlights the importance of not ignoring sudden cognitive changes and seeking medical evaluation for potential nutritional or pathological causes. A balanced diet including meat, eggs, and dairy—natural sources of B12—is recommended, with supplementation under professional guidance when necessary.
