Scientists from the Center for Brain Research in Florence (Italy) found that patients with attention deficit disorder (ADHD) are more likely to hoard unnecessary items than healthy people and patients with obsessive-compulsive disorder (OCD). results published In Journal of Psychiatric Research (JPR).
Researchers have tried to understand what causes pathological hoarding to develop. This is a type of compulsive behavior that involves collecting and storing unused items, most often household items, in such large quantities that they interfere with the intended use of the building and impair the person’s quality of life. To do this, they collected data from 157 adult volunteers, of whom 57 had ADHD, 50 had OCD, and the remaining 50 were mentally healthy. ADHD is a nervous system disorder that occurs in childhood. It is characterized by the inability to control behavior and difficulty maintaining concentration. All participants were asked to complete special questionnaires to assess hoarding and ADHD symptoms.
Results showed that the prevalence of hoarding disorder as a comorbid disorder in adults with ADHD was 32.1%; this rate was significantly higher than in OCD patients (8%) and healthy controls (4%). Additionally, scientists found increased impulsivity in people with comorbid ADHD and hoarding disorder. Researchers suggest that this behavior may be a link between ADHD and pathological hoarding.
