Figure the rest out on your own!

Major depressive disorder cont d
Major Depressive Disorder cont’d

  • Read the case about major depression and answer the following:

    • What are the symptoms?

    • What are the diagnostic criteria for MDD?

    • What are the risk factors?

    • What are the “categories” or “specifiers” in MDD?

    • What can it often be confused with?

    • What other disorders, if any, is it comorbid with?

    • What are some treatment options for those diagnosed?

    • What is the prevalence? Who does it affect most?

3 persistent depressive disorder
3.Persistent Depressive Disorder

Also known as DYSTHYMIA

Can be diagnosed when the mood disturbance continues for at least 2 years in adults or 1 year in children

Not episodic, but CHRONIC

Less severe than Major Depressive Disorder

Affects 0.5% of the population

Differential diagnosis1
Differential Diagnosis

  • You must be careful when diagnosing Persistent Depressive Disorder because it has similar symptoms to:

    • Major depressive disorder

    • Psychotic disorders

    • Depressive disorders related to other medical conditions

    • Substance-induced depression

    • Personality disorders

4 premenstrual dysphoric disorder
4. Premenstrual Dysphoric Disorder

Used to be in the DSM-IV for “further study”

It is now recognized as a formal diagnosis (after 20 years of research!)

Occurs in 1.8%-5.8% of menstruating women

Symptoms worsen as they approach menopause

Oral contraceptives help reduce symptoms

5 substance medication induced depressive disorder
5. Substance/Medication-Induced Depressive Disorder

The symptoms followed with the onset of the substance (drug) or medication

The symptoms persist for at least 1 month even after use has stopped

The disturbance causes clinically significant distress or impairment in social, occupational, or other important areas of functioning

Can not be explained better by another depressive disorder

Can be divided into mild, moderate, or severe

Prevalence is 0.26% in the USA

What do you think the risk factors are?

6 depressive disorder due to another medical condition
6. Depressive Disorder Due To Another Medical Condition

  • Brain damage can definitely lead to depression!

  • Be careful not to confuse it with a medication-induced depression or with an adjustment disorder (imagine having to adjust to having a medical condition )

  • Most common in those who experience:

    • Strokes

    • Huntingtons’s disease

    • Parkinson’s disease
