10%
What is the most common demographic affected by MDD
age
gender
race
socioeconomics
MC in younger populations (average age of onset = 30) and 2-3x more common in women.
Highest prevalence in native americans
Lower in asians/pacific islanders.
higher prevalence in low socioeconomic status

MDD associated with a particular season
To have MDD a patient must have
at least one major depressive episode SIG E CAPS for more than 2 weeks
What is the timeline of depressive episodes
develop over days to weeks and can take about 20 weeks to resolve.
when is the highest risk of recurrence for MDD?
within the first few months following episodes resolution
what are the three ways that the course of MDD can vary among patients
- single major depressive episode that resolves
- multiple episodes with few to no s/s between episodes
- persistent, fluctuating depressive s/s with no clear “remission”
What are the rates of recurrence for MDD
1 year = 40%
lifetime = 85%
What is the Two-Question Screen (PHQ-2)
Quick initial screening for depression that asks for 2 key symptoms of a depressive episode. (depressed mood and anhedonia)
NOT a stand alone test, needs follow up if positive!
What is the Patient Health Questionnaire-9 (PHQ-9)
Further evaluates presence and severity of depression
can be used for initial screening or follow up evaluation
What is the Zung Self-Related Depression Scale
Allow a more in-depth rating of current depressive symptoms

Psychotherapy
Electroconvulsive Therapy (ECT)
Vagal Nerve Stimulation
Transcranial Magnetic Stimulation (TMS)
What are the pharmacological categories for treatment options of MDD
Supplements
Herbals
