I have a 20-year old sister who has never spoken, and never will. AMA.
My sister was born with a neurological disorder, Rett Syndrome, in which she is unable to communicate verbally. She has no functional use of her hands and she cannot do anything for herself. Doctors suspect she has the mental capacity of a 1 year old, but we really have no way of knowing. I am doing this in an effort to spread knowledge and awareness of Rett. Ask anything!
