# Methods  We searched PubMed from time to time during 2015 using the search strategy “("Tic Disorders"[MeSH] OR Tourette NOT Tourette[AU]) AND 2015[PDAT]”. We also reviewed F1000Prime recommendations andnoted  presentations of interest at selected  medical conferences. However, articles were chosen based on a purely subjective assessment of interest, guided by our judgment of their possible future impact on the field.
