His speech is purposeful and full of rhythm when emphasizing a point.
Symptoms include decelerating head growth, resulting in autistic features, loss of skills such as speech and purposeful hand use, irregular breathing patterns, and in many cases seizures.
RTT patients develop normally up to 6 18 months of age, when they start to develop symptoms including loss of speech and purposeful hand movements, seizures, respiratory abnormalities, anxiety and autism [1].
Symptoms of this syndrome are mental retardation, loss of speech and purposeful hand use, autism, ataxia, and stereotypic hand movements.
These include loss of speech and purposeful hand use, stereotypic hand movements, appearance of postnatal microcephaly, autistic features, ataxia, and hand apraxia.
Classic RTT is characterized by apparently normal early development for the first 6 to 18 months of life followed by a period of developmental regression and loss of acquired skills that results in intellectual disability (ID), loss of speech and purposeful hand movements, ataxia, seizures, and respiratory abnormalities.
In the regressive phase, purposeful hand movements and any acquired speech are lost, brain growth decelerates, and ataxia, seizures, autonomic dysfunction and autistic features develop.
Acts of bravery and desperation follow, as do speeches that are too self-consciously purposeful not to be corny.
