MOOD D/O: MDD PREVALENCE - CORRECT ANSWER Twelve-month
prevalence of major depressive disorder in the United States is approximately
7%, with marked differences by age group such that the prevalence in 18- to 29-year-
old individuals
is threefold higher than the prevalence in individuals age 60 years or older. Females
experience
1.5- to 3-fold higher rates than males beginning in early adolescence.
MOOD D/O: MDD DEVELOPMENT AND COURSE - CORRECT ANSWER -
Recovery typically begins within 3 months of onset for two in five individuals with major
depression and within 1 year for four in five individuals.
-The risk is higher in individuals whose preceding episode was severe,
in younger individuals, and in individuals who have already experienced multiple
episodes.
-The persistence of even mild depressive symptoms during remission is a powerful
predictor of recurrence.
MOOD D/O: MDD RISK FACTORS - CORRECT ANSWER -Neuroticism (negative
affectivity) is a well-established risk factor for the
onset of major depressive disorder
-Adverse childhood experiences, particularly when there are multiple experiences of
diverse types, constitute a set of potent risk factors for major depressive disorder.
-Stressful life events are well recognized as precipitants of major depressive
episodes,but the presence or absence of adverse life events near the onset of episodes
does not appear to provide a useful guide to prognosis or treatment selection.
-First-degree family members of individuals with major depressive disorder have a risk
for major depressive disorder two- to fourfold higher than that of the general population.
-Relative risks appear to be higher for early-onset and recurrent forms. Heritability is
approximately 40%, and the personality trait neuroticism accounts
for a substantial portion of this genetic liability.
MOOD D/O: PDD (DYSTHYMIA) DSM5 CRITERIA - CORRECT ANSWER
Depressed mood for most of the day, for more days than not, as indicated by either
subjective account or observation by others, for at least 2 years.
Note: In children and adolescents, mood can be irritable and duration must be at least
,1 year.
B. Presence, while depressed, of two (or more) of the following:
1. Poor appetite or overeating.
2. Insomnia or hypersomnia.
3. Low energy or fatigue.
4. Low self-esteem.
5. Poor concentration or difficulty making decisions.
6. Feelings of hopelessness.
C. During the 2-year period (1 year for children or adolescents) of the disturbance, the
individual has never been without the symptoms in Criteria A and B for more than 2
months at a time.
D. Criteria for a major depressive disorder may be continuously present for 2 years.
E. There has never been a manic episode or a hypomanic episode, and criteria have
never been met for cyclothymic disorder.
F. The disturbance is not better explained by a persistent schizoaffective disorder,
schizophrenia, delusional disorder, or other specified or unspecified schizophrenia
spectrum and other psychotic disorder.
G. The symptoms are not attributable to the physiological effects of a substance (e.g., a
drug of abuse, a medication) or another medical condition (e.g. hypothyroidism).
H. The symptoms cause clinically significant distress or impairment in social,
occupational,
or other important areas of functioning.
Note: Because the criteria for a major depressive episode include four symptoms that
are absent from the symptom list for persistent depressive disorder (dysthymia), a very
limited number of individuals will have depressive symptoms that have persisted longer
than 2 years but will not meet criteria for persistent depressive disorder. If full criteria for
a major depressive episode have been met at some point during the current episode o
MOOD D/O: DYSTHYMIA PREVALENCE - CORRECT ANSWER The 12-month
prevalence in the United States is approximately
0.5% for persistent depressive disorder and 1.5% for chronic major depressive disorder.
MOOD D/O: DYSTHYMIA DEVELOPMENT COURSE - CORRECT ANSWER
Persistent depressive disorder often has an early and insidious onset (i.e., in childhood,
adolescence, or early adult life) and, by definition, a chronic course. Among individuals
with both persistent depressive disorder and borderline personality disorder, the
covariance
of the corresponding features over time suggests the operation of a common
mechanism.
Early onset (i.e., before age 21 years) is associated with a higher likelihood of
comorbid personality disorders and substance use disorders.
MOOD D/O: DYSTHYMIA RISK FACTORS - CORRECT ANSWER -Factors
predictive of poorer long-term outcome include higher levels of neuroticism (negative
affectivity), greater symptom severity, poorer global functioning, and presence of anxiety
disorders or conduct disorder.
,-It is thus likely that individuals with persistent depressive disorder will have a higher
proportion of first-degree relatives with persistent depressive
disorder than do individuals with major depressive disorder, and more depressive
disorders
in general.
-A number of brain regions (e.g., prefrontal cortex, anterior cingulate, amygdala,
hippocampus)
have been implicated in persistent depressive disorder. Possible polysomnographic
abnormalities exist as well.
