Dr. Colm Henry:

There are two elements to this. The distinct transition from childhood to adulthood is not exact. There are different types of presentations, from children to adults, and Senator Murphy has highlighted the challenges among disabled children. In the interests of the public information exercise the Cathaoirleach mentioned, which is appropriate, I will ask Dr. Martin to comment on the signs or symptoms that parents might want to look out for and then Dr. O'Dwyer might describe how it is a little bit simpler in the adult world, although it is still not exact.
