这两天，大家都在讨论“不爱扔东西是不是病”这个问题。其实，很多人都会收集一些对自己有意义的物品，这种怀旧的感性收集行为自然不应该是病了。但是，如果一个人什么东西都不想扔，而且堆在一处影响正常生活，那可能就真是患上“强迫囤积症”了。

Compulsive hoarding (or pathological collecting) is a pattern of behavior that is characterized by the excessive acquisition of and inability or unwillingness to discard large quantities of objects that cover the living areas of the home and cause significant distress or impairment.

强迫囤积症(或病态收集癖)指过度大量收集物品且无法或不愿意丢弃任何物品的行为，收集的这些物品会占去家中很多空间，从而给家人带来不便、增加烦恼。

Prevalence rates of compulsive hoarding have been estimated at 2-5% in adults, and is greater in older adults than younger groups, in men and women, and is inversely related to household income. Hoarding appears to be more common in people with psychological disorders such as depression, anxiety and attention-deficit hyperactivity disorder. (Source: Wikipedia)

据估计，成年人当中患强迫囤积症的约占2-5%，其中，年长者多于年轻人，男女皆有，而且此症比例多与家庭收入成反比。囤积症在患有心理疾病的人群中更常见，如，抑郁症、焦虑症，以及注意力不足过动症等。
