Does "respond better to drugs for bipolar disorder than for depression" mean "respond better to drugs for bipolar disorder than respond better to drugs for depression"?
"drugs for depression" means "drugs that treat depression"?
Context:
Ghaemi is interested in whether such patients might respond better to
drugs for bipolar disorder than for depression. But his colleagues warned him against straying from the
DSM when he applied for funding at the US National Institute of Mental Health (NIMH), because peer reviewers tended to insist on research that hewed to
DSM categories. Ghaemi held off from applying.
