A 56-year-old man presents to the PMHNP, stating he was sent by his wife. He explains he used to own a video rental store, and as a result, he has a large collection of VHS tapes. He continues to collect these "antiques" and does not see any problem with this because they are valuable. He admits he never watches them, because he can never decide which one to watch, and he doesn't have a lot of time. He has started running out of space to keep the tapes, and he admits many of them are probably ruined because they have been housed outside in a hot storage unit. Which diagnosis is most appropriate?

Choice A reason: OCD involves obsessions and compulsions that are distressing and recognized as excessive by the patient. While the patient collects tapes, he does not report intrusive obsessions or ritualized behaviors associated with anxiety reduction, so OCD is less likely. Choice B reason: Delusional disorder involves fixed, false beliefs without insight. The patient does not demonstrate a fixed false belief about the nature of reality; he acknowledges the tapes may be ruined. Choice C reason: Normal collecting behavior involves collecting items without causing significant distress or impairment. In this case, the patient’s hoarding is leading to functional impairment, such as lack of space and potential damage to items, so normal collecting does not fit. Choice D reason: Hoarding disorder is characterized by persistent difficulty discarding possessions, resulting in clutter that disrupts living spaces or functioning. This patient exhibits classic signs: inability to discard items of limited utility, accumulation causing functional impairment, and distress/impairment recognized by family.
