Something can be effective, especially more effective than a placebo, without being a cure. We have many "treatments" for all sorts of illnesses where the treatment isn't a cure. SSRIs for depression are a treatment, not a cure, just as one example. Hell, even Nyquil is a treatment for symptoms without being a cure.

When it comes to mental health we also have these big umbrella categories (depression, schizophrenia) that are made up of groups of illnesses. Schizophrenia has so many different causes, and thus different treatments, that viewing it as a single illness can actually be problematic.

Anyways, my point is that what you're saying makes no sense at all.
