# Methods  We searched PubMed through April, 2016,  using the search strategy: ("Tic Disorders"[MeSH] OR Tourette NOT Tourette[AU]) AND 2015[PDAT]. This search returned 202 citations on 22 Jan 2016. 2016, and includes articles appearing online in 2015 but not officially published by year end (from journals that still focus on the paper user interface).  We also reviewed F1000Prime recommendations and presentations of interest at selected medical conferences. Articles were chosen based on a purely subjective assessment of interest, guided by our judgment oftheir  possible future impact on the field. Many sections conclude with short tables providing briefer comments about listing  additional articles.
