Researchers have identified an increased likelihood of hoarding in people with ADHD; this finding may indicate a greater need for storage options among people with ADHD who are not hoarding. Morein-Zamir and colleagues report that “Whilst formerly associated with Obsessive-Compulsive Disorder (OCD), it is now recognised that individuals with HD [hoarding disorder] often have inattention symptoms reminiscent of Attention Deficit/Hyperactivity Disorder (ADHD). Here, we investigated HD in adults with ADHD. . . . Clinically significant hoarding symptoms were found in ∼20% versus 2% of ADHD and control groups. . . . Patients with ADHD had a high frequency of hoarding symptoms, which were specifically linked to inattention.”
