There are many subtypes of depression, and this can be important when selecting the best medication. Today I will be going over these subtypes and will be giving you the algorithm for each as to what I would pick first, second, third, and so forth. Knowing this may lead to going with an MAOi or TCA, for example, much sooner than you thought you would, which can lead to faster resolution of symptoms for the patient. I'll talk about Treatment-Resistant Depression, Atypical Depression, Melancholic Depression, Anxious Depression (Depression with anxiety distress), Depression with Mixed Features, Psychotic Depression, Seasonal Affective Disorder, and I'll briefly mention catatonia and peri-partum depression which I will go into more detail later. So, if you aren't familiar with all of these and you aren't aware of the differences in med choices for each, you'll definitely want to listen to this episode!
