What Is Rett Syndrome?
8. Symptoms
It is not usually until after 6 months that any symptoms start to show, and even then they can be barely noticeable. After around 1 year to 18 months, however, the symptoms can begin to be considerably more noticeable. The type of symptoms the patient has, and their severity, can also vary considerably in different cases. Rett syndrome will typically cause the patient to grow more slowly than they should.
Their head will also likely be smaller, as will their brain. They can begin to lose control over their movements, and muscles can become weak, and/or rigid. The patient will also lose communication skills, although these can return to a degree. Unusual eye movements are another potential symptom, as are unusual hand movements. Other symptoms include an irregular heartbeat, breathing problems, crying, and seizures.
