“…Nine datasets were available to be included as whole-brain t-maps in the current meta-analysis (4,18,19,24,26,35,37,41,51). Peak coordinate data from a whole-brain analysis were available for a tenth dataset for the between-group errors contrast (40).…”

“…These findings, however, are inconsistent, and most studies focused on compulsive hoarding as a subtype of OCD. Only one fMRI study reveals that HD patients diagnosed with DSM‐5 criteria exhibited significantly greater activity than controls in the anterior cingulate cortex and right dorsolateral prefrontal cortex during conflict‐monitoring and response‐inhibition conditions in the Go/No‐Go task . As far as we know, no studies have examined the structural changes relevant to hoarding by applying the diagnostic criteria of HD in the DSM‐5.…”

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.

“…First, hoarding symptoms in the context of OCD may be neurologically different from HD. Several neuroimaging and neurophysiological studies have shown that individuals with OCD with hoarding show different patterns of activity from individuals with OCD without hoarding (Hough et al, ; Mataix‐Cols et al, ; Mathews, Perez, Delucchi, & Mathalon, ; Saxena et al, ).…”

Hoarding: A meta‐analysis of age of onset

Hoarding disorder is present in 2-6% of the population and can have an immense impact on the lives of patients and their families. Before its inclusion the Diagnostic and Statistical Manual of Mental Disorders, 5th edition, pathological hoarding was often characterized as a symptom of obsessive-compulsive disorder, and several different diagnostic assessment methods were used to identify and characterize it. Although the age of onset of pathological hoarding is an important epidemiological measure, as clarifying the age of onset of hoarding symptoms may allow for early identification and implementation of evidence-based treatments before symptoms become clinically significant, the typical age of onset of hoarding is still uncertain. To that end, this study is a systematic review and meta-analysis of research published in English between the years 1900 and 2016 containing information on age of onset of hoarding symptoms. Twenty-five studies met inclusion criteria. The mean age of onset of hoarding symptoms across studies was 16.7 years old, with evidence of a bimodal distribution of onset. The authors conclude by discussing practice implications for early identification and treatment.
