The clinical features of psychogenic movement disorders resembling tics
Abstract
BACKGROUND: Psychogenic movement disorders (PMDs) may be difficult to differentiate from organic abnormal movements. METHODS: We aimed to characterise the prevalence and clinical features of PMDs resembling tics during the last 3.5 years in our centre. RESULTS: We studied 9 patients (five females) with psychogenic tics representing 4.9% of all 184 patients first evaluated for a PMD during the study period. The mean age at onset was 34.1 years. Lack of premonitory sensations, absence childhood and family history of tics, inability to suppress the movements and coexistence with other PMDs and pseudoseizures were common in our patients. Compared with 273 patients with Tourette syndrome, those with PMDs resembling tics were older: 36.3 versus 18.7 years (p=0.014) at presentation and more frequently female (p=0.030). CONCLUSIONS: Movements resembling tics are observed in a small proportion of patients with PMDs. Clinical features can help to differentiate them from organic tics.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
