I believe one of the biggest issues in psychology today is finding a balance between drug prescription and counseling. There is no wonder drug that can cure all brain-based mental disorders, thus it is important to continue research on better localization of drugs entering the brain in order to target certain cortical (or subcortical) regions rather than widely dispersing anti-depressants throughout the entire brain. This only one part of the equation.
The other part requires effort on the behalf of the patient being willing to change, causing reorganization of certain neural networks via plasticity.
Only by looking at a patient's individual needs and history can psychologists find a balance between prescription and counseling. Obviously there is no set guidelines for how much to prescribe and when, since we barely know the functional interworkings of brain regions. Hopefully the "wow" factors of anti-depressants as a cure-all will quickly fade and balance will begin to prevail.
