Apart from the typical motor symptoms, it has become evident in the last decennia that patients with Parkinson’s disease (PD) suffer from non-motor impairments including cognitive dysfunctions. Our research team, linking together the laboratories of cognitive psychology (N. Deroost) and neurological rehabilitation (E. Kerckhofs and E. Swinnen), investigates motor learning in patients with PD bridging those two domains. More concretely the capacity for (implicit) learning of motor sequences is examined in relation to the progression of the disease. Also the effect of brain modulation by transcranial direct current stimulation (tDCS) on implicit sequence learning is studied. In a large interuniversity research program the role of cognitive impairment in freezing of gait was examined (PhD study of Dr. Jochen Vandenbossche). Currently Drs. Mahyar Firouzi investigate the effects of tDCS on implicit motor sequence learning, when delivered over (a) the primary motor cortex and (b) the cerebellum of patients with Parkinson’s disease and age-matched healthy controls.
