Exam Tips
- →When evaluating biological treatments, always discuss both their strengths (e.g., effectiveness for severe symptoms, speed of action) and weaknesses (e.g., side effects, dependency, symptom focus, ethical concerns).
- →For each treatment (e.g., antidepressants, ECT), be prepared to explain its proposed mechanism of action (how it works) and its specific applications (which disorders it treats).
