The scatter-hoarding behavior of granivorous rodents plays an important role in seed dispersal and seedling regeneration of trees, as well as the evolution of several well-known mutualisms between trees and rodents in forest ecosystems. Because it is difficult to identify seed hoarders and pilferers under field conditions by traditional methods, the full costs incurred and benefits accrued by s...

This paper reports on and synthesizes new research that examines how a collaborative community response can promote successful aging in place for older adults with hoarding behaviour. Through interviews with older adults with hoarding behaviour, who used a particular community support and a focus group interview with members of the community collaborative that directed supports for this populat...

Food deprivation stimulates foraging and hoarding and to a much lesser extent, food intake in Siberian hamsters. Leptin, the anorexigenic hormone secreted primarily from adipocytes, may act in the periphery, the brain, or both to inhibit these ingestive behaviors. Therefore, we tested whether leptin given either intracerebroventricularly or intraperitoneally, would block food deprivation-induce...

This article discusses the nature and treatment of compulsive hoarding among children. We summarize the phenomenology of compulsive hoarding, including its clinical presentation, comorbidity with varied mental disorders, and associated impairment. The limited data on treatment outcome are presented along with a behavioral framework that we utilized to treat youth who hoard. Our approach is high...

Hoarding disorder (HD), a recent addition to DSM-5, is characterized primarily by difficulty in discarding current possessions, urges to save items, and excessive clutter in the home. In addition to HD, hoarding behaviors may result from obsessive-compulsive disorder (OCD), schizophrenia, depression, and even some eating disorders. DSM-5 criteria for HD necessitate that the hoarding behaviors c...

The aim of this pilot randomized controlled trial was to investigate whether an extended, standardized program of computer-assisted cognitive remediation (CR; a behavioral intervention designed to improve cognitive function through repeated task practice and strategy acquisition) improves disordered attention and related cognitive functions in patients with hoarding disorder (HD) as compared to...

Deterioration in the ability to perform "Activities of daily living" (ADL) is an early sign of Alzheimer's disease (AD). Preclinical behavioural screening of possible treatments for AD currently largely focuses on cognitive testing, which frequently demands expensive equipment and lots of experimenter time. However, human episodic memory (the most severely affected aspect of memory in AD) is di...

Corvids (crows, jays, magpies and nutcrackers) are important dispersers of large-seeded plants. Studies on captive or supplemented birds suggest that they flexibly adjust their scatter-hoarding behaviour to the context of social dynamics and relative seed availability. Because many corvid-dispersed trees show high annual variation in seed production, context-dependent foraging can have strong e...

Circulating concentrations of the stomach-derived "hunger-peptide" ghrelin increase in direct proportion to the time since the last meal. Exogenous ghrelin also increases food intake in rodents and humans, suggesting ghrelin may increase post-fast ingestive behaviors. Food intake after food deprivation is increased by laboratory rats and mice, but not by humans (despite dogma to the contrary) o...

OBJECTIVE Little is known about the age-specific prevalence of hoarding and obsessive compulsive symptoms (OCS), particularly in older age groups. The objectives of this study were to estimate the age-specific prevalence, severity, and relationships between hoarding and OCS in males and females using a large population-based sample. METHODS We assessed the age-specific prevalence rates of hoa...
