Rett Syndrome

When a girl presents a loss of acquired skills and repetitive hand movements, it is worth seeking specialized guidance, since these signs may point toward Rett syndrome. It is a neurodevelopmental disorder of genetic origin that almost always affects girls.

What it is: It usually appears after the first few months of apparently typical development, with a halt and then a regression of motor and communication abilities.

Signs that are usually observed:

• Stereotyped hand movements
• Difficulties with language and walking
• Changes in the rate of head growth

Who evaluates it? The pediatric neurologist, together with the pediatrician and communication professionals such as the speech-language pathologist, take part in its study and support. In the presence of warning signs in development, the advisable course is to discuss it with these professionals without delay.
