NCT ID NCT00768820
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at thinking and mental health issues in people with Velocardiofacial, Williams, and Fragile X syndromes. Researchers will test how well medications like methylphenidate, fluoxetine, and risperidone improve these symptoms. The goal is to better understand and treat these conditions.

- What this could lead to
- If successful, this could help identify which medications best manage psychiatric and cognitive symptoms in these genetic syndromes.
- What could go wrong
- This is a Phase 4 study with a small, specific population, so results may not apply broadly. Medications may cause side effects or not work for everyone.
