ASD is a pretty broad term for a diverse mental state. Sometimes a treatment for some other ‘disorder’ will work for an ASD person. Its good to hear your wife has found something that works for her. What helps me manage my sensory issues and by proxy mood is cannibis (luckily im in a country that allows legal access). But i probably wouldnt have to take meds at all if the world wasnt a sensory hell hole and even though it benefits me it might not benefit another person. The biggest help though. Having love support and understanding when things are tough.
