I cant answer your question only your treatment providers can say whether your alter has a learning disorder.

what I can say is that I had a learning disorder as a child so when my mind created alters of course there was one with a learning disorder.

also in general even normal children mimic what they hear and ask to have things repeated many times. normal children are very good about acting in a way that makes the adults think wait a minute here you cant really be this way you must be pretending to be so naive or smart. either you are 10 going on 5 or 5 going on 10.

my point if this can happen to and with normal children it can happen with someones alternate personalities.

but in order to find out if this is whats going on with in you, you will need to contact your or a mental health treatment provider who can assess the situation.
