What are the statistics for Depressive Disorders in Canada?
- In Canada:
- Depressive disorders are MOST common in adolescence and early adulthood (15-24 years of age)
- Through adolescence and adulthood (15-64 years of age) WOMEN have a higher prevalence of depressive disorders compared to men.
- Older adults (65 and older) have the lowest prevalence of depressive disorders, and no significant difference between men and women.
What are the MDD Specifiers?
- With anxious distress
- With mixed features
- With melancholic features
- With atypical features
- eg. ??? ask prof
- With mood-congruent psychotic features
- consistent with cognitive content
- eg. it would be better if you weren’t here, ppl don’t like you
- With mood-incongruent psychotic features
- opposite of their depressive moods, but don’t lift mood
- With catatonia
- sit or stand in rigid position
- With peripartum onset
- during or after pregnancy
- With seasonal pattern (recurrent episode only)
What are the risk factors for depression?
- Age - more often starts in younger adulthood
- 20s and 30s
- Socioeconomic status
- Marital status
- for men
- Women are nearly twice as likely as men to develop major depression
- due to socialization factors more than physical factors
- women may be taught to be more passive in terms of problem-solving, may not be taught to face problems head on
- Less pronounced difference in later years
- Greater array of life stressors?
- maybe monthly menstrual cycles as well
- due to socialization factors more than physical factors
- Coping styles
- street drugs and alcohol tend to subvert psychotropic medication effects
- if you are on meds and start using street drugs - >effectiveness of meds will go out the window

- once process has begun they may have trouble shaking it
- Prevalence: 10 to 15%.

What is a manic episode in bipolar disorder?
- Periods of unrealistically heightened euphoria, extreme restlessness, and excessive activity characterized by disorganized behaviour and impaired judgment.

- they may get irritable or laugh it off if you don’t understand them
What is the rapid flight of ideas in bipolar disorder?

What is the DSM-5 Criteria for a Manic Episode?
A. A distinct period of abnormally and persistently elevated, expansive, or irritable mood and abnormally and persistently increased goal-directed activity or energy, lasting at least 1 week and present most of the day, nearly every day (or any duration if hospitalization is necessary)
B. During the period of mood disturbance and increased energy or activity, three (or more) of the following symptoms (4 if the mood is only irritable) and present to a significant degree and represent a noticeable changes from usual behaviour:
- If a period if hospitalization is present → almost a pathognomic indicator if these symptoms are present
1. Inflated self-esteem or gradiosity
2. Decreased need for sleep (eg. feels rested after only 3 hours of sleep). 3. More talkative than usual and pressure to keep talking.
- Flight of ideas or subjective experience that thoughts are racing.
- Distractibility (ie. attention too easily drawn to unimportant or irrelevant external stimuli), as reported or observed.
- lack of selective attention
- Increase in goal-directed activity (either socially → eg asking out sb who isn’t into them at all), at work or school, or sexually) or psychomotor agitation (ie. purposeless non-goal-direct activity)
- Excessive involvement in activities that have a high potential for painful consequences (eg. engaging in unrestrained buying sprees, sexual indiscretions, or foolish business investments)
- eg no medical compliance → not willing to take meds
What is the DSM-5 Criteria for Bipolar I Disorder?
A. Criteria have been met for at least one manic epsiode.
B. The occurrence of the manic and major depressive episode(s) is not better explained by schizoaffective disorder, schizophrenia, schizophreniform disorder, delusional disorder, or other specified or unspecified schizophrenia spectrum and other psychotic disorder.
- So really, Dx. of a Manic Episode is usually tantamount to a Bipolar I Dx.
What is the DSM-5 Criteria for Hypomanic Episode?
A. A distinct period of abnormally and persistently elevated, expansive, or irritable mood and abnormally and persistently increased activity or energy, lasting at least 4 consecutive days and present most of the day, nearly every day.
