This is probably a really stupid question, and I'm sorry in advance, but does Downs Symdrome have different levels of disability?

[saltire]

Not sure if that's the correct terminology.
There is a woman, with Downs, who gets on the same bus as me, has done for weeks. Inf act several weeks ago i defended her when some teenagers were having a go.
She has no difficulty in getting on, knows where to get off etc, but just recently a young man with Downs has been getting on, his mum tells the driver where to let him off, she takes him to his seat, etc and then she gets off the bus, and he is met by someone in town, a carer I think who takes him shopping, and holds his hand or arm the whole time. Meanwhile the woman gets off, and goes off shopping just like any other young woman
I know many lead perfectly normal(lives, but I am genuinely curious if it has differeing levels of disability, or if it is how the parents and the family and support netwroks help the person who has Downs.

I can tell I'm not explaining myself very clearly am I?

Bumping for you, but the answer to this is yes. I have a friend whos adult child has Down's syndrome in its mosiac form - (where not all cells have an extra bit of chromosome 21) and she leads a fairly independent life. I also know another family whos adult son also has autism and needs a very much higher level of support.
