31 Second, hoarding has been linked to poorer health status. Individuals who hoard are very likely to be overweight or obese and suffer from a severe medical condition.31

Third, several clinical and community studies have reported a low rate of marriage among compulsive hoarders.14,29,32,33 Those who are married or cohabitating tend to have a lower degree of hoarding severity31 Fourth, hoarding is associated with high rates of family frustration. Family members who cohabit with hoarders report being embarrassed about Inhibitors,research,lifescience,medical the condition of their home, arguing about the selleckchem clutter, and feeling rejection and hostility toward the hoarder.31 In summary, emergent research suggests that the prevalence of compulsive Inhibitors,research,lifescience,medical hoarding ranges from 2% to 5%, and men may be more likely to hoard than women. In most cases, hoarding is a chronic disorder. Although some people may experience a gradual rise in symptoms throughout their lifetime, others

may develop hoarding symptoms quite quickly after a stressful life event. Men and women who hoard may experience different cooccurring Inhibitors,research,lifescience,medical disorders, yet both genders are likely to experience a substantial amount of burden associated with their hoarding. Neuropsychological impairment Neuropsychological research into hoarding did not begin to build until the last decade. The initial clues that hoarding was related to frontal-lobe dysfunction came from case reports of pathological collecting and saving that began after a brain injury, typically along with other changes in personality and social functioning.34-36 In the last decade, two papers presented findings suggesting that hoarding is the result of frontal-lobe lesions. In the first report, Hahm and colleagues36 described the case of a 46-year-old Korean man who began Inhibitors,research,lifescience,medical unusual collecting Inhibitors,research,lifescience,medical behavior after he suffered an injury to his left ventromedial prefrontal cortex and caudate. This man had difficulty with social decisionmaking and judgment processes. In the second report, Anderson et al37 examined compulsive hoarding behavior within a sample

of 86 patients with focal lesions, and found that 13 of these participants exhibited abnormal collecting behavior. Magnetic resonance imaging Levetiracetam (MRI) showed that all 13 individuals with hoarding symptoms had damage to the mesial frontal region of the brain, including the right polar sector and anterior cingulate. If excessive collecting and saving behaviors can begin after brain injury, individuals who hoard in the absence of lesions may possess similar deficits in neuropsychological functioning or impaired self-regulation that contribute to compulsive hoarding symptoms. Self-report and laboratory studies of neuropsychological functioning in hoarding have highlighted potential areas of subtle impairment. In a study by Hartl et al, hoarding patients reported increased symptoms of attention deficit-hyperactivity disorder (ADHD).
