Which of the following is NOT TRUE about hoarding disorder?

参考解析：

细节理解题。根据文章第九段的内容“Hoarding disorder is defined as having an excessive number of items, having persistent difficulty throwing possessions away and storing them in a chaotic manner, to such an extent that this interferes with everyday living and causes significant distress or affects quality of life.”可知，囤积障碍被定义为拥有过多的物品，持续难以扔掉财物，并以混乱的方式储存，以至于干扰了日常生活，造成严重的痛苦或影响生活质量，故A项和B项均正确；根据文章第八段第二句“But last month hoarding was recognized as a psychiatric disorder in its own right by the World Health Organization.”可知，上个月，世界卫生组织（World Health Organization）承认囤积本身就是一种精神障碍，故C项是错误的；根据文章第七段第二句“But, like many, she didn’t think it was something doctors would treat, so she didn’t seek help.”可知，但是，像许多人一样，她认为这不是医生能治疗的问题，所以觉得没必要向医生求助，故D项是正确的。故选C。
