I know a mother who fought like hell to get her son, who she was afraid of, treated. Finally UCLA got him straightened out - at least for the time being. After trying various meds prescribed by various doctors that didn’t work UCLA “washed” his system and then put him on something else and now he’s a really good kid. Yet to reach puberty however.
It’s difficult because children at that age are simply changing physically so fast that even medications can’t keep up with them.
Puberty is a big challenge, because usually it is a few years after that when adolescents have their first big crisis (age 16 or so).
But it seems that the parents you know are plugged into help and maybe things will go well for them. Prayers for this family.
