Like most human behaviors, saving and collecting possessions can range from totally normal and adaptive to excessive or pathological. Hoarding, or compulsive hoarding, are some of the more commonly used terms to refer to this excessive form of collectionism. Hoarding is highly prevalent and, when severe, it is associated with substantial functional disability and represents a great burden for t...

The adult female rats hoard large quantities of food during proestrus and continue hoarding if ovariectomised at proestrus (Group I). The hoarding score is lowest in diestrus and continue to remain low if ovariectomised during this phase (Group II). The scores in Group I and Group II are reversed in intracerebral administration of Progesterone and Estradiol Benzoate respectively into preoptic a...

Background: Previous literature on Hoarding Disorder (HD) has largely recruited individuals with selfidentified hoarding difficulties or informant-ratings of individuals who are not seeking help. Little is known about the reliability of selfand informant-ratings of hoarding severity and insight, and whether individuals who self-identify with HD differ from those who do not. Method: Twenty-four ...

of a thesis at the University of Miami. Hoarding is a debilitating disorder that has gained increasing interest in recent years, contributing to its re-classification as a discrete condition. However, much remains unclear about its underlying mechanisms of risk, though evidence implicates information processing deficits. In particular, the domain of inattention has been highlighted in extant cl...

Although differences in food-hoarding tactics both reflect a behavioral response to cache pilferage among rodent species and may help explain their coexistence, differentiation in cache pilfering abilities among sympatric rodents with different hoarding strategies is seldom addressed. We carried out semi-natural enclosure experiments to investigate seed hoarding tactics among three sympatric ro...

Scatter hoarders are not able to defend their caches. A longer hoarding distance combined with lower cache density can reduce cache losses but increase the costs of hoarding and retrieving. Scatter hoarders arrange their cache density to achieve an optimal balance between hoarding costs and main cache losses. We conducted systematic cache sampling investigations to estimate the effects of food ...

Keen-Rhinehart E, Bartness TJ. Leptin inhibits food-deprivation-induced increases in food intake and food hoarding. Am J Physiol Regul Integr Comp Physiol 295: R1737–R1746, 2008. First published October 1, 2008; doi:10.1152/ajpregu.90512.2008.—Food deprivation stimulates foraging and hoarding and to a much lesser extent, food intake in Siberian hamsters. Leptin, the anorexigenic hormone secrete...

Hoarding disorder, newly included as a separate diagnostic entity in the Obsessive-Compulsive and Related Disorders section of DSM-5, has been reported to have significantly different symptoms and etiology than obsessive-compulsive disorder (OCD). However, the validity of this new diagnosis in China - where the storing of possessions is sanctioned and normalized - remains to be proven. We consi...

While there is considerable evidence that the factors involved in hoarding typically begin to manifest early in life (mostly in adolescence), the majority of those sampled in research studies are in their later years. As so much of our understanding of the psychological factors involved in hoarding is derived from those who are older and more chronically affected, the core hoarding psychopathol...

41 Abstract Objective: Compulsive hoarding remains a significant public health issue, with many sufferers failing to acknowledge the problem. A number of methodological approaches have been utilised to explore and explain this complex phenomenon, though few have made use of contemporary visually inspired approaches. In an earlier study, it was found that visual methods proved beneficial in the ...
