Study Population

Individuals with Hoarding Disorder and Healthy Participants

Description

Identify inclusion criteria.

Inclusion criteria for participants diagnosed with HD:

  1. ages 18-70
  2. primary diagnosis of hoarding disorder
  3. sufficient severity of hoarding symptoms
  4. stable on psychotropic medications for 1 month prior to study enrollment
  5. capacity to provide informed consent
  6. ability to tolerate clinical study procedures

Inclusion criteria for healthy control participants:

  2. capacity to provide informed consent

Identify exclusion criteria.

Exclusion criteria for participants with HD:

  1. psychiatric or medical conditions that make participation unsafe
  2. pregnant or nursing females
  3. concurrent use of any medications that might increase the risk of participation (e.g. drug interactions)
  4. presence of metallic device or dental braces

Exclusion criteria for healthy control participants:

  1. any current or lifetime psychiatric diagnosis
  2. current or past use of psychotropic medication
  3. pregnant or nursing females
  4. major medical or neurological problem
  5. presence of metallic device or dental braces

Design Details

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Hoarding Disorder
Adults diagnosed with Hoarding Disorder
Device: MRI with fMRI frequency
Functional magnetic resonance imaging or fMRI measures brain activity by detecting changes in blood flow. Participants will do cognitive tasks during fMRI.
Healthy Controls
Adults without mental illness
Device: MRI with fMRI frequency
Functional magnetic resonance imaging or fMRI measures brain activity by detecting changes in blood flow. Participants will do cognitive tasks during fMRI.
