Prof. dr. Teus van Laar

Professor of Neurology

Prof. Van Laar is clinical neurologist by training, with special expertise in Movement Disorders, especially on Parkinson’s disease (PD) and the effect of pharmacological interventions on this disease. The first years of his career have been focused on the treatment of advanced patients with PD, whereas at that time apomorphine was introduced in Europe. He has significantly contributed to the clinical dossier necessary to register apomorphine in the Netherlands. After its introduction he has performed multiple studies to establish the effect of apomorphine on motor- and non-motor aspects of PD. Thereafter, the focus of his interest moved towards the non-motor aspects of PD, especially on the cognitive deterioration, accompanied by visual hallucinations. He was one of the first neurologists in the Netherlands, examining the clinical effect and adverse effects of rivastigmine in PD dementia, and contributed to a pivotal study, published in the NEJM  (Emre et al, NEJM 2004; 351:2509-18).
