A juvenile Peruvian bear, of the species Tremarctos ornatus,¹ presented to the emergency department after being found unconscious at 32 Windsor Gardens, London, England.² The bear had been struck in the left posterior head region by a returning boomerang. On assessment, he demonstrated retrograde amnesia and language-related symptoms. When offered a bun, one of the patient’s favourite things to eat, he replied by asking, “What’s a bun?” Later, he demonstrated a pattern of repetitive behavior in which he forced air through pursed lips to generate a “phew” sound. Finally, the patient attempted to request a cup of tea, but was unable to produce the name of the desired item. These deficits persisted for 24 hours and then resolved completely.

在英格兰伦敦的32座温莎花园不知情的情况下，一头秘鲁秘鲁小熊Tremarctos ornatus物种¹出现在急诊室。²一只熊被返回的回旋镖击中了左后头部区域。经评估，他表现出逆行性健忘症和语言相关症状。当给他一个面包，这是病人最喜欢吃的东西之一时，他回答说：“什么是面包？” 后来，他表现出一种重复的行为模式，在这种行为中，他迫使空气通过pur起的嘴唇发出“ phe”声。最终，患者尝试要求一杯茶，但无法提供所需物品的名称。这些缺陷持续了24小时，然后完全解决了。
