| Atypical Rett syndrome (disorder) | | Atypical Rett syndrome | | A neurodevelopmental disorder that is diagnosed when a child presents with a Rett-like syndrome but does not fulfil all the diagnostic criteria for typical Rett syndrome. Several subvariants have been defined; the early-onset seizure type (Hanefeld), congenital variant (Rolando), the 'forme fruste' type, the late childhood regression form and the preserved speech variant (PSD or Zappella variant). Diagnosis relies on clinical evaluation using the diagnostic criteria for atypical Rett originally defined by Hagberg in 1994: an atypical case must meet at least three of the six main criteria and at least five of the eleven supportive criteria. | | atypisch Rett-syndroom |
