What two neurotransmitters are most implicated in the pathophysiology of mood
disorders? - ANSWER: norepinephrine and serotonin
How are dopamine levels affected in depression and mania? - ANSWER:
Dopamine activity may be reduced in depression and increased in mania
How does depression affect sleep neurophysiology? - ANSWER: Loss of deep
(slow-wave) sleep
Increase in nocturnal arousal.
The latter is reflected by four types of disturbance: (1) an increase in nocturnal
awakenings, (2) a reduction in total sleep time, (3) increased phasic rapid eye
movement (REM) sleep, and (4) increased core body temperature. T
What is the most common abnormality found in structural and functional brain
imaging in depressive disorders? - ANSWER: Increased frequency of abnormal
hyperintensities in subcortical regions, such as periventricular regions, the basal
ganglia, and the thalamus
What cognitive distortions are commonly seen in depressed patients? - ANSWER:
(1) views about the self —a negative self-precept, (2) about the environment—a
tendency to experience the world as hostile and demanding, and (3) about the
future—the expectation of suffering and failure

What is learned helplessness? - ANSWER: the hopelessness and passive
resignation an animal or human learns when unable to avoid repeated aversive
events
What "specifiers" are used to describe patients with various mood disorders? -
ANSWER: Table 8.1-7
What factors are associated with a poor prognosis for patients with mood
disorders? - ANSWER: MDD: The percentage of patients recovering after
repeated hospitalization decreases with passing time. Generally, as a patient
experiences more and more depressive episodes, the time between the episodes
decreases, and the severity of each episode increases.
Bipolar I: Have a poorer prognosis than do patients with major depressive disorder.
About 40 to 50 percent of patients with bipolar I disorder may have a second manic
episode within 2 years of the first episode. poor occupational status, alcohol
dependence, psychotic features, depressive features, interepisode depressive
features, and male gender were all factors that contributed a poor prognosis. Short
duration of manic episodes, advanced age of onset, few suicidal thoughts, and few
coexisting psychiatric or medical problems predict a better outcome.
Bipolar II: The course and prognosis of bipolar II disorder indicate that the
diagnosis is stable because there is a high likelihood that patients with bipolar II
disorder will have the same diagnosis up to 5 years later. Bipolar II disorder is a
chronic disease that warrants long-term treatment strategies.
What is endogenous depression? - ANSWER: depression with no apparent cause
What characteristics would the clinician see if a patient presented with atypical
features in a depressed patient? - ANSWER: Catatonic features
Postpartum onset
,3|Page
Rapid cycling
Seasonal features
Significant weight gain
Hypersomnia
Leaden paralysis
What diagnostic criteria are required for a patient to receive a diagnosis of Major
Depressive Disorder? - ANSWER: *Five (or more) of the following symptoms
have been present during the same 2-week period and represent a change from
previous functioning; at least one of the symptoms is either (1) depressed mood or
(2) loss of interest or pleasure.
Depressed most of the day, nearly every day as indicated by subjective report
(e.g., feels sad, empty, hopeless) or observation made by others (e.g., appears
tearful)
Markedly diminished interest or pleasure in all, or almost all, activities most of the
day, nearly every day (as indicated by subjective account or observation)
Significant weight loss when not dieting or weight gain (e.g., change of more than
5% of body weight in a month), or decrease or increase in appetite nearly every
day
Insomnia or hypersomnia nearly every day
Psychomotor agitation or retardation nearly every day (observable by others, not
merely subjective feelings of restlessness or being slowed down)
Fatigue or loss of energy nearly every day
, 4|Page
Feelings of worthlessness or excessive or inappropriate guilt (which may be
delusional) nearly every day (not merely self-reproach or guilt about being sick).
Diminished ability to think or concentrate, or indecisiveness, nearly every day
(either by subjective account or as observed by others)
Recurrent thoughts of death (not just fear of dying), recurrent suicidal ideation
without a specific plan, or a suicide attempt or a specific plan for committing
suicide
The symptoms cause clinically significant distress or impairment in social,
occupational, or other important areas of functioning.
The episode is not attributable to the physiological effects of a substance or to
another medical condition.
The occurrence of the major depressive episode is not better explained by
schizoaffective disorder, schizophrenia, schizophreniform disorder, delusional
disorde
What are some common sleep disturbances experienced by patients with MDD? -
ANSWER: Insomnia, hypersomnia.
What psychomotor changes would the clinician see when interviewing a patient
with MDD? - ANSWER: Psychomotor retardation is the most common.
Psychomotor agitation is also seen, especially in older patients.
Agitation: Hair pulling, hand-wringing.
