|October 16, 2014
Summary
Psychogenic tics (PT) are rare, affecting 1.9% of patients, and often present in adulthood with complex movements. Diagnosis requires identifying atypical symptoms differentiating them from organic tics.
Area of Science:
- Neurology
- Psychiatry
- Clinical Medicine
Context:
- Tic disorders encompass a range of conditions, including Gilles de la Tourette syndrome (GTS).
- Psychogenic tics (PT) are a less understood subtype, often presenting distinct clinical features.
- Differentiating PT from organic tics is crucial for accurate diagnosis and management.
Purpose:
- To determine the prevalence of psychogenic tics (PT) within a cohort of patients presenting with tic phenotypes.
- To characterize the clinical features and diagnostic indicators of PT.
- To explore the relationship between PT and pre-existing organic tic disorders.
Summary:
- Psychogenic tics (PT) were identified in 5 out of 268 patients (1.9%), predominantly in adults (17-51 years).
- Key features included vocalizations, complex movements, absence of simple motor tics, and lack of suppressibility.
- PT were observed in individuals with a history of childhood organic tics, and treatment was largely ineffective.
Impact:
- This study highlights the rarity of PT and provides specific clinical characteristics for their identification.
- Understanding these features aids clinicians in distinguishing PT from organic tics, improving diagnostic accuracy.
- The findings suggest PT may co-occur with or arise in the context of organic tic disorders, necessitating tailored diagnostic approaches.

Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...
