What Is Rett Syndrome?
4. Stage 1
Rett syndrome develops in 4 main stages. The first of these, stage 1, is known as early onset. During this first stage, the symptoms of the condition are mild to the point where they will often go unnoticed. This stage will usually not start until 18 months at the most, and it can last for months, or even up to a year.
The patient might not be sitting or crawling as other children of the same age will be. However this, if noticed, will often be put down to some babies developing faster than others. The patient may also show less interest in playing with their toys, and they may also start making less eye contact.
