Bipolar half Flashcards
Dramatic Increase cause?
Increase may reflect earlier under-diagnosis, current over-diagnosis, possibly a true increase in prevalence, or some combination of these factors
This increase emphasizes the need for research that validates the diagnosis of bipolar disorder in children and the importance of developing treatments that are safe and effective
Symptoms / Characteristicsand Key Terms
An episode or cycle is the period of a mood
Mania: abnormally elevated mood causing impairment
Hypomania: shorter in duration than mania and does not cause marked impairment in functioning
Elevated mood: being inappropriately happy
Labile: fast changing, easily altered mood
Mixed states: symptoms of mania & major depression during same episode
Irritable mood: temper tantrums & rages not proportionate to the event
Symptom Presentation in Children/Adolescents
Irritable mood (vs. sad/euphoria in adults) present in almost all
cases
Rapid shifts in mood and energy
Elated mood during manic episode
Mixed episodes (simultaneous manic & depressive symptoms) at same time / same day
Short durations (several hours; several days, consecutive days)
Increased verbalizations
Distractibility
Inflated self-esteem
Decreased need for sleep
More likely to experience mixed states
Manic Episodes
Distinct period of abnormally elevated (irritable) mood and abnormally and persistently increased goal directed activity or energy clearly different from usual mood; duration: most of day nearly every day for at least 1 week
Sufficiently severe to cause marked impairment in social or occupational functioning or to necessitate hospitalization to prevent harm to self of others, or there are psychotic features
Hypomanic Episode

Major Depressive EPISODE (not DISORDER)
5 or more of the following symptoms present during the same 2 week period and represent change from previous functioning. One symptom has to be depressed mood or loss of pleasure

DSM-5 Criteria
Bipolar 1 and 2
Presence of at least 1 manic episode during a person’s life time
- Manic episode is a change from typical functioning & causes significant impairment
- No depression requirement, but manic episode is often preceded by or may be followed by a major depressive episode
Bipolar 2 Disorder
Must meet criteria for current or past hypomanic episode AND current or past major depressive episode
Bipolar 1 and 2 Specifiers
With anxious distress With mixed features With rapid cycling With mood-congruent psychotic features With mood-incongruent psychotic features With catatonia With peripartum onset With seasonal pattern
Bipolar 1 only
With melancholic features
With atypical features
Rapid Cycling/ Mixed Features Specifiers
Rapid Cycling Specifier:
-Presence of at least 4 mood episodes in previous 12 months that meet criteria for manic, hypomanic or major depressive episode
Mixed Features:
-During manic or hypomanic episode, at least three symptoms of depression are present
-During major depressive episode, at least three manic/hypomanic symptoms are present
Cyclothymic Disorder
- For at least 2 years (1 year in children and adolescents) there have been numerous periods with hypomanic symptoms that do not meet criteria for a hypomanic episode and numerous periods with depressive symptoms that do not meet criteria for a major depressive episode
- During 2 year period (1 year for children/adolescents), the hypomanic and depressive symptoms have been present for at least half the time and the individual has not been without a symptom for more than 2 months at a time
- Criteria for major depressive, manic, or hypomanic episode has not been met.
Diagnostic Issues
- Developmental criteria
- Differential diagnosis
- Determining end of episodes
- Not due to substance-induced mania
- Misperceptions of the symptoms especially when there are comorbid conditions
- Bipolar I was often diagnosed as schizophrenia
Impairment
Domains of Impairment
- Family – family conflict
- Social- peer rejection
- Emotional
- Executive function & cognitive performance
- Education / vocational difficulties
- Poor educational attainment
- Adjustment – substance use, incarceration, suicide, hospitalizations
Prevalence Rates Overall
The 12-month prevalence in the United States is 0.6% for Bipolar I
- 12-month prevalence in United States is 0.8% for Bipolar II
- 12-month prevalence of Bipolar I across 11 countries ranged from 0% - 0.6%.
- 12-month prevalence of Bipolar II internationally is 0.3%
Prevalence Rates of Bipolar Disorder in Children and Adolescents
One community study showed a lifetime prevalence of bipolar disorder of 1% in youths aged 14 to 18 years, using the Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS) (Lewinsohn et al., 1995)
-Brotman and colleagues (2006) found the lifetime prevalence of severe mood dysregulation to be 3.3% in children aged 9 to 19 years from an epidemiological study sample
