Perhaps. Perhaps those diagnoses of ASD are actually incorrect and the correct diagnosis is EUPD, theories and practices change, it wont be the same in 10, 20 50 years time
If she is ASD then she shouldnt be in hospital, there are big drives in clinical practice to prevent and avoid ND clients being admitted, so if she is then even more of an argument to be discharged much sooner than she was
However, whatever the diagnosis, the issue is the same, she didnt need to be in hospital, caused disruption and distress to other vulnerable patients and so yes she was 'trouble', theres no other word for it when others are on the recieving end
And if you come across a man acting in the way she did, he would be seen as more than 'trouble', the descriptors for a man like that would be abusive, controlling, NPD, anti social PD, sociopathic, violent and he would be arressted.
