### Premonitory urges  Premonitory urges are usually reported later in life than tics are first observed. However, a large case series (_N_>1000) from one clinic suggests that premonitory urges “emerge much earlier than previously thought”: by age 8-10, >60% of children reported premonitory urges, and >75% could suppress tics \cite{27672357}. Urges also “were found to be highly associated with ‘not just right experiences’.” The early onset of tic suppression is consistent with a report from the author's laboratory on tic suppression in the first few months of tic disorder onset \cite{25220075}.  \cite{Brandt_2016} performed a clever and well-thought-out careful  experiment to investigate the timing of urges in relation to tics, compulsions and—as a comparison to a naturally arising urge—blinks when attempting to keep the eyes open. Another group examined tics and urge to tic at 10- to 15-second intervals in 12 patients with moderate to severe TS; different patients had quite different relationships between urge and tic timing when examined at this temporal scale \cite{26255052}. These observations show that careful phenomenological studies still have much to teach us about tic disorders. ### Other
