Thomas Szazs, MD

- Criticized medical model as turning people into passive “patients” instead of active controllers of their own lives
77
adv/disadvantages of DSM-5
adv: can be a useful tool for diagnosis and treatment, provides structure for research/insurance
dis: number of disorder increases w/each edition, gives illusion of objectivity, people may live up to labels

80
Theories of where depression comes from

87
biological treatment
-involve use of drugs, electroconvulsive therapy (ECT), brian surgery or other models that affect brain or body chemistry
-can be effective, because most disorders have a biological basis
88
off-label prescription
- drug not approved by FDA
-Side effects may be feel worse than the disorder symptoms
-especially bad with Lithium and antipsychotics, leading to high relapse and dropout rates
89
tardive dyskinesia

- a chronic condition that causes involuntary, repetitive movements in the body
90
concerns of biological treatment
- Some effects overstated due to publication bias
