Disorder
major depressive disorder (MDD)
one of the most common mental disorders
-Approximately 7.1% of adults in the U.S. had episode in last year, prevalence highest
(13.1%) among individuals aged 18-25

Chronic condition characterized by extreme fluctuations in mood, energy, and ability to
function
-Moods may be manic, hypomanic, or depressed and may include mixed mood or
psychotic features
-many have only experienced only one manic episode in their lifetime
,-Mood fluctuations may be separated by periods of high stability or may cycle rapidly
-diagnosed when a client has one or more episodes of mania or hypomania with a
history of one or more major depressive episodes
-high risk for suicide - answer-Bipolar disorder (BD)
characterized by a persistently elevated, expansive, or irritable mood. Related
symptoms may include inflated self-esteem, increased goal-directed activity or energy,
including grandiosity, decreased need for sleep, excessive talkativeness, racing
thoughts, flight of ideas (FOI), distractibility, psychomotor agitation, and a propensity to
be involved in high-risk activities. Mania leads to significant functional impairment and
may include psychotic features or necessitate hospitalization - answer-mania
requires at least one episode of mania for at least one week (or any duration if
hospitalization due to symptoms is required) - answer-Bipolar Type I:
diagnosis requires a current or past hypomanic episode and a current or past major
depressive episode. Symptoms last for at least 4 days but fewer than seven.
-Hypomanic symptoms are not of sufficient duration or severity to cause significant
functional impairment, psychosis, or hospitalization.
-Anger and irritability are common.
-Clients often enjoy the elevation of mood and are reluctant to report these symptoms,
making bipolar more difficult to diagnose if the client presents in the depression phase.
- answer-Bipolar Type II:
involves the chronic presentation of hypomanic and depressive symptoms that do not
meet the diagnostic criteria for a major depressive or manic/hypomanic episode. -
answer-Cyclothymia:
antidepressant therapy may precipitate a manic episode or induce rapid-cycling bipolar
depression
-may contribute to the increased incidence of death by suicide in children and adults
younger than 25 - answer-If bipolar depression is mistaken for MDD:
,monotherapy
-Antidepressants should be combined with a mood stabilizer to prevent the onset of a
hypomanic or manic episode - answer-Antidepressants are used cautiously in clients
with bipolar disorder and never as ________________.

appetite changes - answer-5HT, NE Dysfunction causes what mood related symptoms
-depression occurs as a result of a deficiency of one or all three monoamine
transmitters
• serotonin, norepinephrine, and dopamine
-while mania may result from an excess - answer-monoamine hypothesis of depression
• Selective Serotonin Reuptake Inhibitors (SSRIs)
, • Serotonin Norepinephrine Reuptake Inhibitors (SNRIs)
• Norepinephrine Dopamine Reuptake Inhibitors (NDRI)
• Serotonin Antagonist and Reuptake Inhibitors (SARIs) - answer-Medication
Management for Depression, First-Line Treatment:
Mechanism of action
• inhibit 5-HT reuptake
Adverse effects
-diarrhea
-headache
-weight gain
-sexual side effects - answer-SSRI's
Mechanism of action
• inhibit 5-HT reuptake
• inhibit NE reuptake (increase energy, focus)
• increase DA in prefrontal cortex (increase cognition)
Adverse effects
-elevated blood pressure
-anxiety
-insomnia
-constipation - answer-SNRI's
Mechanism of action
• inhibit DA reuptake (increase alertness, motivation)
• inhibit NE reuptake (increase energy)
Adverse effects
-agitation
