need to critique something (DSM classification system used in psychiatric diagnoses) using a Marxism perspective

I need to come up with a thesis for a 10 page essay for a theory course. Since I am a psychiatric nurse, I thought I would critique the evolution of the DSM- the classification system used in mental health. I don't foresee difficulties there; however, in not being very familiar with Marxism, I am having difficulties coming up with an outline. If I were to use Marxism, how would I set this up- would I be looking at the political, the social or the economic aspects behind the making of the DSM or all of them? Thank you.
