ABSTRACT Hoarding behavior has been reported in several mental disorders and is occasionally reported by the caregivers of dementia patients. Such behavior may have adverse effects on the patients and increase the burden of the caregivers. This study was conducted to investigate the prevalence of hoarding behavior in patients with dementia and identify the characteristics and psychiatric symptoms associated with it. The sample was 133 dementia patients admitted to a geropsychiatric ward. Of the 133 dementia patients, 30 (22.6%) showed hoarding. Hoarding was found in various types of dementia. Patients with hoarding had a higher prevalence of repetitive behaviors, hyperphagia, and pilfering. Results suggested that hoarding behavior is a common symptom in dementia patients and a complex phenomenon. Better understanding of the underlying pathogenesis may highlight specific pharmacological or behavioral methods for treatment of the behavior.

    ABSTRACT: Hoarding has been considered a subtype of obsessive-compulsive disorder (OCD). Planned revisions to the diagnostic criteria propose that hoarding form a separate diagnosis in a larger category of obsessive compulsive related disorders. To date, there have been few direct comparisons between hoarding and those with other symptoms of OCD. This study builds on work that suggests compulsive hoarding, while similar to OCD, comprises a clinically distinct condition. Three groups were compared: those with OCD without compulsive hoarding symptoms (n=102), those with compulsive hoarding but not OCD (n=21), and individuals who satisfied both criteria (n=25). The groups were compared on obsessionality, compulsivity, overvalued ideas, depression, and anxiety. The two hoarding groups were also compared on hoarding symptoms and savings cognitions. Results indicated that the hoarding-only group reported fewer symptoms than both OCD groups, including fewer obsessions and compulsions and lower depression. Both hoarding groups showed significantly higher overvalued ideas when compared to the OCD-only group. These results suggest that hoarders experience less subjective distress than those with OCD, yet have greater difficulty in challenging dysfunctional cognitions associated with the presenting condition. These findings suggest that individuals with hoarding, whether with or without OCD, will show greater difficulty engaging in cognitive-behavioral interventions.

    ABSTRACT: Hoarding can be a symptom of multiple neurological and psychiatric disorders, including obsessive-compulsive disorder (OCD). Recent evidence suggests that, in many cases, hoarding can also be a standalone problem that presents independently from other conditions; this has led to the proposal of a new diagnostic entity named hoarding disorder. This article reviews the neuropsychological and neuroimaging research on pathological hoarding. Most research in humans has been conducted in the context of individuals with brain damage, dementia, or OCD. Studies of well-characterized samples of individuals with hoarding disorder are extremely rare. Although not possible to establish firm conclusions at this stage, we conclude with a series of observations and recommendations for clinical practice.
