And an SSRI in such a case?
Might actually work and is part of the first line treatment, obviously combined with HAART.
There's no point, Riax, but I do admire your perseverance!
The problem with Psychiatry and the DSM is that all the conditions is classified according to symptoms. Where as in other specialities, it is classified according to anatomy (e.g. Hepatic conditions) or aetiology (e.g. Infection, haemostatic imbalances, etc).
The reason for this is that when they first started with the DSM criteria, they knew very little of how the brain works, so they organized it according to symptoms. What happened over the years is that one moment a condition would be classified as for example, an anxiety disorder, but then they decide it looks rather like a personality disorder.
Now because they know so little of the brain (even today) they struggle to classify according to aetiology.
There are several triggers for depression like physical loss (family member, financial stability), emotional (poor relationships). Depression also has a genetic component: you are more likely to get depression if you have a close family member with depression.
But the exact mechanism(s) is not yet understood. They do know that serotonin plays an integral part and hence the different antidepressants.
The current first line treatment for a major depressive episode is an SSRI like fluoxetine. A very large percentage of patients relapse after treatment and need to stay on their medication for the rest of their life.
Depression should be approached according to the Biopsychosocial model, since it's probably multifactorial in origin. Meaning: the patient should be on an antidepressant, but that's not the most important aspect and it will probably not cure him.
Psychological counselling is highly recommended, but not 3 monthly. Weekly if possible (which never is). They must also get the family involved in the patient's recovery, the patient needs a good social support structue where he feels loved etc.
But this is, at best, only symptomatic treatment because we're not sure about the exact aetiology. We're also not sure whether it's real depression. It can be personality disorders, bipolar disorders, anxiety disorders, etc.
When looking at a depressed patient multiaxial classification, they very seldomly only have depression noted on it, but rather some comorbidities like financial or relationship difficulties, poor social structures, personality traits, chronic medical conditions.
In the ideal world, pharmacological treatment should only be considered as treatment if Major Depressive Disorder is the only condition on the axis. If there is any other condition on the axis, pharmacological treatment should only be considered supportive (unless a pure biological depression has been diagnosed).
But until we know more about the brain and the aetiology for its conditions, let's continue with our multifactorial approach to treating depression and other ailments of the mind.
Whether it's your multivitamins, thyroid medication,ECT, frontal lobectomies*, holy water or antidepressants. If it works, it works.
Depression is "all in your mind" after all.
*I'd advice against this form of treatment...
