“…The participants in the current HD group had high rates of comorbidities with other psychiatric disorders, which may affect the high proportion taking psychiatric medication. The top two comorbidities and their comorbid rate (MDD 56.7%, ADHD 26.7%) in the current HD group were similar to those of previous studies (Frost et al, 2011;Grisham et al, 2010;Tolin et al, 2018). It is noteworthy that the HD group in our study had a high rate of comorbidity with ADHD, similar to previous studies (Frost et al, 2011;Sheppard et al, 2010), despite not being recruited in medical institutions where many ADHD patients were treated.…”

“…As clinical characteristics of HD, previous studies have reported familiality (Iervolino et al, 2009;Pertusa et al, 2008;Samuels et al, 2007;Steketee et al, 2015), high unmarried rate (Kim et al, 2001), early onset (during childhood or adolescence; Grisham et al, 2006;Landau et al, 2011;Tolin et al, 2010a), a chronic course (Ayers et al, 2010;Grisham et al, 2006;Tolin et al, 2010a), and poor insight (Jakubovski et al, 2011;Matsunaga et al, 2010;Tolin et al, 2010b;Torres et al, 2012). Moreover, several recent studies have reported high rates of comorbidities with HD, including depressive disorders, anxiety disorders, impulse control disorders, and attention-deficit/hyperactivity disorder (ADHD; Frost et al, 2001;Frost et al, 2011;Mueller et al, 2009;Samuels et al, 2002;Sheppard et al, 2010;Tolin et al, 2018;Tolin et al, 2012a). Previous studies have suggested that hoarding is associated with ADHD (Grisham et al, 2007;Grisham et al, 2010;Hartl et al, 2005;Park et al, 2016).…”

“…Recent studies have also reported the possibility of cognitive impairment in HD (Grisham and Baldwin, 2015;Woody et al, 2014), such as information processing problems in hoarding patients (Blom et al, 2011;Frost and Hartl, 1996;Grisham et al, 2010;Mackin et al, 2011;Mackin et al, 2016;Pushkarskaya et al, 2018;Raines et al, 2014;Steketee and Frost, 2003;Wincze et al, 2007) and the impairment of attention, memory, and executive function in HD (Ayers et al, 2016;Ayers et al, 2013;Steketee and Frost, 2003;Tolin et al, 2018;.…”

Previous studies have reported clinical characteristics of hoarding disorder (HD), such as early onset, a chronic course, familiality, high unmarried rate, and high rates of comorbidities. However, clinical research targeting Japanese HD patients has been very limited. As a result, there is a low recognition of HD in Japan, leading to insufficient evaluation and treatment of Japanese HD patients.The aim of the current study was to delineate the clinical characteristics of Japanese HD patients. Thirty HD patients, 20 obsessive-compulsive disorder (OCD) patients, and 21 normal controls (NC) were targeted in this study.The HD group had a tendency toward higher familiality, earlier onset, and longer disease duration compared to the OCD group. In addition, the HD group showed a significantly higher unmarried rate than the NC group. The top two comorbidities in the HD group were major depressive disorder (56.7%) and attention-deficit/ hyperactivity disorder (26.7%). The HD group had significantly higher scores on hoarding rating scales and lower scores on the Global Assessment of Functioning Scale than the other two groups.The current study showed a clinical trend in Japanese HD patients similar to previous studies in various countries, suggesting that HD may be a universal disease with consistent clinical symptoms.

“…In the future, we should discuss the independency of HD when it has comorbid OCD or ASD. We speculate that patients with HD share a biological background involving neurocognitive impairment, such as decision‐making, attention switching, and inattention . Further, based on our clinical experience, we suppose that environmental factors, such as loss experiences, strengthen emotional‐attachment behavior.…”

Hoarding disorder (HD) is a newly listed disease in the new category of Obsessive–Compulsive and Related Disorders in the DSM‐5. Patients with HD find it difficult to discard possessions regardless of their actual value and to organize those things. As a result, the possessions overflow the living space and hinder living functions. Though the hoarding symptom had been regarded as a subtype of obsessive–compulsive disorder (OCD) to date, recent studies have revealed many differences in clinical characteristics, including onset, course, degree of insight, and treatment responses, between hoarding and other subtypes. Moreover, several neuroimaging studies have found specific changes of brain structure and function in OCD patients with hoarding symptoms compared to patients with non‐hoarding OCD. Meanwhile, strategies for treatment of HD have not been standardized. At present, psychological treatment using cognitive behavioral therapy techniques has a certain effect. In this review, we outline the pathophysiology and treatment of HD.

“…In particular, distractibility is a promising potential mediator. Impaired capacity to sustain attention is perhaps the most robust neuropsychological finding in HD (Woody et al, 2014), and subjective distractibility shows a larger difference between HD and healthy control participants than do other subjective cognitive functions (Tolin, Hallion, et al, 2018). Distractibility may contribute to difficulty discarding by impeding task persistence; improved focus, conversely, might mediate improved discarding and decreased clutter over the course of treatment.…”

Objective: Hoarding disorder (HD) is a common and potentially debilitating psychiatric disorder. Thus far, psychological treatments have yielded modest effects and/or were time-consuming and costly to deliver. The aim of the present study was to test the efficacy of a brief group cognitive-behavioral therapy (CBT) for adults with HD and to test hypothesized mediators of treatment outcome. Method: Eighty-seven adults with a primary diagnosis of HD were randomized to either immediate CBT or wait list. CBT consisted of 16 weekly, 90-min group sessions that emphasized in-session practice of discarding and refraining from acquiring, decision-making and problem-solving training, emotional distress tolerance, motivational interviewing strategies, and contingency management. Participants were assessed at pretreatment, midtreatment, and posttreatment by an independent evaluator unaware of treatment condition. Results: CBT was efficacious for the symptoms of HD compared with wait list. Saving-related cognitions, but not subjective cognitive impairment, partially mediated treatment outcomes. Conclusion: Brief Group CBT is an efficacious and feasible treatment for adults with HD, and is partially mediated by reductions in maladaptive beliefs about possessions. Superiority trials comparing CBT to active treatments, and additional research into mechanisms of treatment outcome, are warranted. What is the public health significance of this article?Hoarding disorder (HD) is a common and often severe psychiatric illness. As a new diagnosis, it has received less research attention than many other disorders. Treatment efficacy for HD also lags behind that of many other psychiatric disorders. This study suggests that a relatively brief (16session) Group CBT is efficacious for adults with HD, with 83% of patients classified as improved. These results support the consideration of Group CBT as a first-line treatment for HD.
