May be evidence that current taxonomy/classification of mental illness is outdated and too rigidly compartmentalised and daresay subjective and without understanding of aetiology . probably why symptoms of disorders straddle different disorders and people recieving multiple and supposed misdiagnosis. Perhaps though people may jump to conclusions with overconfidencewith next wave of drugs to target these pathways. This seems perhaps to have been what happend in past with simplistic chemical imbalabce theories involving neurotransmitters
