BACKGROUND Prior studies have suggested unique patterns of neural activity associated with compulsive hoarding. However, to date no studies have examined the process of making actual decisions about whether to keep or discard possessions in patients with hoarding symptoms. An increasing body of clinical data and experimental psychopathology research suggests that hoarding is associated with imp...

Compulsive hoarding is a disabling psychological disorder characterized by excessive collecting and saving behavior. This article reviews four key areas of recent advances in hoarding research. First, we provide an overview of the evolving controversy regarding the diagnostic status of hoarding, highlighting accumulating evidence that it may be best conceptualized as a separate syndrome. Second...

Food hoarding plays an important role in the energetic repertoire of a variety of mammalian species. Both food hoarding and food intake have been examined in rodents using several energetic challenges including food deprivation, treatment with metabolic fuel blockers, and enhancement of fuel storage. In the present experiment, we examined food hoarding by female jirds (Meriones shawi), a desert...

Despite the long-held view that hoarding is a symptom of both obsessive-compulsive disorder and obsessive-compulsive personality disorder, increased evidence has emerged during the last 20 years suggesting that hoarding represents a distinct form of psychopathology. This study reflects the discussions on the nosological status of hoarding carried out by the WHO ICD-11 Working Group on the Class...

OBJECTIVE This study was conducted to examine whether pediatric patients with obsessive-compulsive disorder (OCD) and hoarding symptoms differed in terms of clinical characteristics from pediatric OCD patients without hoarding symptoms. METHOD Eighty children and adolescents with OCD (range, 7-17 years) completed clinician-administered and parent- and child-report measures of OCD symptom seve...

Teubner BJ, Keen-Rhinehart E, Bartness TJ. Third ventricular coinjection of subthreshold doses of NPY and AgRP stimulate food hoarding and intake and neural activation. Am J Physiol Regul Integr Comp Physiol 302: R37–R48, 2012. First published October 19, 2011; doi:10.1152/ajpregu.00475.2011.—We previously demonstrated that 3rd ventricular (3V) neuropeptide Y (NPY) or agouti-related protein (Ag...

Hoarding of objects, trash, or animals has the potential to harm hoarders and others. Law enforcement and civil concerns arise, leading to situations ranging from health code violations to child abuse and potential eviction proceedings. DSM-5 included hoarding disorder among the obsessive-compulsive and related disorders. This change has created an opportunity for individuals who engage in seve...

We analyze the trade-off faced by growth firms between hoarding cash (and delaying investment) and incurring dilution from external financing. Such nonprecautionary hoarding features a self-reinforcing effect: firms with better investment opportunities hoard less, yet grow successful and cash-rich more quickly. We show that non-precautionary hoarding affects the choice between public and privat...

BACKGROUND Acquiring and discarding objects are routine decision processes for most people. Despite the ubiquitous need to make such decisions, little is known about how they are made and what goes wrong when individuals acquire and fail to discard so many items that many areas of their home become unlivable (i.e., clinical hoarding). We hypothesize that clinical hoarding reflects a normal vari...

Agouti-related protein (AgRP), an endogenous melanocortin 3/4 receptor antagonist, appears to play an important role in the control of food intake and energy balance because exogenous administration in rats and overexpression in mice result in hyperphagia and body mass gain. Furthermore, arcuate nucleus AgRP mRNA is increased with fasting in laboratory rats and mice and is decreased with refeed...
