Rett's syndrome

Related people

A symptom complex only observed in girls, with the main features of autism, dementia, ataxia and purposeless hand movements.

Description

A symptom complex only observed in girls. The child develops normally for 6 to 12 months, and then the disease manifests in the age 6 months to 4 years. It is a progressive neurodevelopmental disorder characterised by acquired microcephaly, severe dementia, autism, purposeless hand movements, characteristic hand-wringing stereotypy, and jerky ataxia of the trunk. Hypotonia (loss of muscle tone) is usually the first symptom. Inheritance is probably X-linked dominant with lethality in the hemizygous males. The disorder was originally described by Andreas Rett of Austria in 1966, but was not known worldwide until two decades later following a report by Hagberg et al describing 35 affected girls from Sweden, Portugal, and France. The syndrome affects approximately 1 in every 10,000-15,000 live female births. The gene causing the disorder has now been identified.

In the spring of 1965, Andreas Rett observed two young girls sitting on their mothers’ laps in his waiting room. Like mirror images of each other, they were petite and profoundly disabled and were wringing their hands together incessantly. After searching his files, Dr. Rett found six other girls with a similar clinical picture and wrote the first description of the syndrome that now bears his name.

bright eyes
sweet smile
clasped hands
unique style

special child
secret mind
loving heart
one of a kind

so we thought
but 'tis not true
now we find she is one of a few
