Hoarding is seen in several psychiatric conditions, but has not been specifically assessed in Parkinson's disease (PD). This study investigates hoarding tendency amongst patients with PD, and its association with impulsive‐compulsive spectrum behaviors (ICBs). We compare clinical features, measures of hoarding, impulse buying, self‐control, obsessive‐compulsive symptoms, depression, and anxiety in 39 patients with PD with ICBs (PD + ICB), 61 patients with PD without ICBs (PD − ICB), and 50 healthy controls. A much higher proportion of PD + ICB (27.8%) than PD − ICB (3.5%) were hoarders ( P = 0.001). 6% of healthy controls were hoarders. Compulsive shoppers scored higher than other varieties of ICB on excessive acquisition measures. Hoarding correlated positively with impulsive buying, obsessive‐compulsive symptoms, PD duration, and negatively with self‐control measures. Using multivariate regression analyzes, the presence of ICBs and measures of impulsive buying were the only variables independently associated with hoarding in PD. The association of hoarding with other ICBs and low trait impulse control suggests that excessive hoarding is related to the spectrum of impulsive behaviors in PD. © 2010 Movement Disorder Society
