Isn't this covered by "situational depression" (adjustment disorder with depressed mood) VS "clinical depression" (major depressive disorder), and the fact that diagnosis entails excluding physical conditions that cause similar symptoms?

None of the various depressive disorders (nor other psychiatric disorders) deal with defining a cause, but with describing a set of symptoms.

The treatment is similar regardless. Which is the real issue I am getting at.

The point I am arguing agrees with the second thing you mentioned, psychiatry is about treating the symptoms not cause.

Should they be both treated using the same medication?

Situational depression doesn't "count" as real depression.
