Motor and vocal tics are common in childhood. The received wisdom among clinicians is that for most children the tics are temporary, disappearing within a few months. However, that common clinical teaching is based largely on biased and incomplete data. The present study was designed to prospectively assess outcome of children with what the current nomenclature calls Persistent Tic Disorder. We identified 43 children with recent onset tics (mean tic onset 3.3 months) and re-examined 39 of them on the 12-month anniversary of their first tic. Tic symptoms improved on a group level at the 12-month follow-up. Remarkably, however, tics were present in all children at follow-up, with some only apparent when observed remotely by video. Our results suggest that remission of Provisional Tic Disorder appears to be the exception rather than the rule. We also identified several clinical features present at the first examination that predict one-year outcome.
