    Saccadic Direction Errors are Associated with Impulsive Compulsive Behaviours in Parkinson's Disease Patients
    (IOS Press, 2019) Barbosa, Pedro; Kaski, Diego; Castro, Patricia; Andrew, Andrew; Warner, Thomas; Djamshidian, Atbin
    Fifteen individuals with Parkinson's disease (PD) and impulsive compulsive behaviours (PD+ICB) were compared to 15 PD patients without ICBs (PD-ICB) and 15 healthy controls (HC) on a pro-saccades and an anti-saccades task to assess if ICBs are associated with distinct saccadic abnormalities. PD+ICB made shorter saccades than HC and more direction errors in the anti-saccades task than PD-ICB and HC, suggesting that patients with ICBs have greater difficulty in suppressing automatic saccades towards a given target. Saccadic assessment has the potential to evolve into a marker to guide therapeutic decisions in patients at risk of developing ICBs.
