Mood Disorder
• Characterized by disturbances in feelings,
thinking, and behavior that tend to occur on a
continuum, ranging from severe depression to
severe mania (hyperactivity).
• Is the most common psychiatric diagnoses
associated with suicide.
• Two Categories:
a. Major Depressive Disorder
b. Bipolar Disorder (Manic-Depressive Illness)
1. Major Depressive Disorder
• Characterized by at least two weeks of a depressed mood or
loss of interest in pleasure and activities.
•
Also includes at least 4 of the following symptoms of depression:
a. Increase or decrease in appetite
b. Increase or decrease in sleep
c. Psychomotor agitation or retardation
d. Feelings of worthlessness or guilt
e. Fatigue and loss of energy
f. Decreased ability to think and concentrate
g. Recurrent thoughts of suicide
•
These symptoms must be present everyday for 2 weeks and result in
significant distress or impair important areas of functioning.
•
Referred to as PSYCHOTIC DEPRESSION if combined with delusions and
hallucinations.
2. Bipolar Disorder
• Diagnosed when a person’s mood cycles between
extremes of mania and depression.
• Mania – an emotional state characterized by elation, high
optimism, increased energy, and an exaggerated sense of
importance and invincibility.
• May last for about 1 week but may be longer for some individuals.
• At least 3 of the following symptoms accompany the manic
episode:
a. Inflated self-esteem or grandiosity
b. Decreased need for sleep
c. Pressured speech
d. Flight of ideas
e. Distractibility
f. Increased involvement in goal-directed activity or
psychomotor agitation
g. Excessive involvement in pleasure-seeking activities with a
high-potential for painful consequences
2. Bipolar Disorder
• HYPOMANIA – a period of abnormally and persistently
elevated, expansive, or irritable mood lasting for days
and including 3 or 4 of the additional symptoms
described earlier.
• MIXED EPISODE
- Diagnosed when the person experiences both mania and
depression nearly everyday for at least 1 week.
- A person with mixed episodes experiences both mood "poles"-mania and depression--simultaneously or in rapid sequence.
• BIPOLAR I DISORDER – one or more manic or mixed episodes
usually accompanied by major depressive episodes.
• BIPOLAR II DISORDER – one or more major depressive episodes
accompanied by at least one hypomanic episode.
Related Disorders
• Dysthymic Disorder - Characterized by at least 2 years of
depressed mood for more days than not with some
additional, less severe symptoms that do not meet the
criteria for a major depressive episode.
- This disorder usually does not affect social or
occupational functioning.
• Cyclothymic Disorder – characterized by at least 2 years of several
periods of hypomanic symptoms not as severe as those in a manic
episode.
• Substance-Induced Mood Disorder – characterized by a prominent
and persistent disturbance in mood that is judged to be a direct
physiologic consequence of ingested substances.
• Mood Disorder due to a general medical condition
- Characterized by a prominent and persistent disturbance in
mood that is judged to be a direct physiologic consequence of a
medical condition.
Other Disorders
• Seasonal Affective Disorder (SAD) – 2 Subtypes:
- WINTER DEPRESSION OR FALL-ONSET SAD: people experience
increased sleep, appetite and carbohydrate cravings; weight gain;
interpersonal conflict; irritability; and heaviness in the
extremities beginning in late autumn and abating in spring and
summer.
- SPRING-ONSET SAD: less common; with symptoms of insomnia,
weight loss, and poor appetite lasting from late spring or early
summer until early fall.
• Postpartum or “Maternity” Blues
- Frequent, normal experience after delivery of a baby.
- Symptom begin approximately 1 day after delivery, usually peak
in 3 to 7 days, and disappear rapidly with no medical treatment.
Other Disorders
• Postpartum Depression
- Meets all the criteria for a major depressive episode,
with onset within 4 weeks of delivery.
• Postpartum Psychosis
- A psychotic episode developing within 3 weeks of
delivery and beginning with fatigue, sadness,
emotional lability, poor memory, and confusion and
progressing to delusions, hallucinations, poor insight
and judgment, and loss of contact with reality.
- Considered a medical emergency that requires
immediate treatment.
Etiology
BIOLOGIC THEORIES
• Major Depressive Disorder
- 3 times more common among first-degree
biological relatives.
- Twin studies reveal a higher rate of concordance
in monozygotic twins than dizygotic twins.
• Bipolar Disorder
- The risk increases 4% to 24% in first-degree
relatives of people with bipolar disorder.
- Twin studies of monozygotic twins indicate a
65% concordance rate.
Etiology
NEUROCHEMICAL THEORIES
• Biogenic Amine Theory
- Depressive Disorder: ↓ NE and serotonin
- Bipolar Disorder: ↑ NE and serotonin
• Kindling Theory
- External environmental stressors activate internal
physiologic stress responses, which trigger the first
episode of a mood disorder, the first episode then creates
electrophysiologic sensitivity to future episodes so that
less stress is required to evoke another episode.
Etiology
NEUROENDOCRINE INFLUENCES
Depression
• Increased cortisol secretion in 40% of clients.
• Increased thyroid-stimulating hormone in 5% to 10% of clients.
PSYCHODYNAMIC THEORIES
• Freud: looked at the self-depreciation of people with
depression and attributed that self-reproach to anger turned
inward related to either a real or perceived loss. (Introjection)
• Bibring: believed that one’s ego aspired to be ideal and that to
be loved and worthy, one must achieve these high standards.
Depression results when, in reality, the person was not able to
achieve these ideals all the time.
Etiology
PSYCHODYNAMIC THEORIES
• Jacobson: ego is a powerless, helpless child victimized by the
superego.
• Mania episodes: “defense” against underlying depression, with
the id taking over the ego acting as an undisciplined hedonistic
being.
• Meyer: depression as an reaction to a distressing life experience
• Horney: children raised by rejecting or unloving parents were
prone to feelings of insecurity and loneliness, making them
susceptible to depression and helplessness.
• Beck: depression results from specific cognitive distortions in
susceptible people; involves magnification of negative events
and minimization of anything positive.
Major Depressive Disorder
• Involves 2 or more weeks of a sad mood or lack of
interest in life activities with at least 4 other
symptoms of depression.
• Twice as common in women than men.
• Has 1.5 to 3 times greater incidence in first-degree
relatives than in the general population.
• Its incidence decreases with age in women and
increases with age in men; single and divorced
people have the highest incidence.

Tiredness
Worthlessness or guilt inappropriate to the situation
Difficulty thinking, focusing or making decisions.
Hopelessness, helplessness, and/or suicidal ideation.
Major Depressive Disorder
Onset and Clinical Course
• An untreated episode of depression can last 6 to 24
months before remitting.
• 50% to 60% of people who have one episode of
depression will have another.
• After a second episode, there is 70% chance of
recurrence.
Treatment and Prognosis
• Psychopharmacology (TCAs, MAOIs, SSRIs, Atypical
Antidepressants)
Major Depressive Disorder
• Psychotherapy
- Interpersonal Therapy: focuses on difficulties in
relationships, such as grief reactions, role
disputes, and role transitions.
- Behavior Therapy: seeks to increase the
frequency of the client’s positively reinforcing
interactions with the environment and to
decrease negative interactions.
- Cognitive Therapy: focuses on how the person
thinks.
Major Depressive Disorder
Electroconvulsive Therapy
- Involves application of electrodes to the head of the
client to deliver an electrical impulse to the brain; this
causes a seizure.
- It is believed that the shock stimulates brain chemistry
to correct the chemical imbalance of depression.
- A series of 6 to 15 treatments is scheduled 3 times a
week.
- The client receives a short-acting anesthetic so he or she
is not awake during the procedure.
- A muscle relaxant is given to relax all muscles that will
greatly reduce the outward signs of the seizure.
Major Depressive Disorder
Electroconvulsive Therapy
- After the therapy:
a. The client may be confused; provide frequent orientation and
reassurance.
b. Assess the gag reflex prior to giving the client fluid, foods, or
medication.
- Potential Side Effects:
a. Major side effects with bilateral treatment are confusion,
disorientations, and short-term memory loss.
b. The client may be confused and disoriented on awakening.
c. Memory deficits may occur, but memory usually recovers
completely; although some clients have memory loss lasting
up to six months.

Depression
Assessment
• History
- It may take several short periods to complete the assessment
because clients who are severely depressed feel exhausted and
overwhelmed.

episodes of depression, treatment, and client’s response to
treatment; and family history if suicide.
• General Appearance and Motor Behavior
- Looks sad and ill; slouched posture, makes minimal eye contact.

energetic, and sleepless; they have poor judgment,
rapid thoughts, actions, and speech.
• Onset and Clinical Course

escalation of symptoms over a few days, and last
from a few weeks to several months.
- They tend to be briefer and to end more suddenly
than depressive episodes.

•
•
•
•
•
•

Bipolar Disorder
Treatment
Psychopharmacology
• Lithium:
- For bipolar mania but could also partially or completely

- Contraindicated during pregnancy.
• Anticonvulsant Drugs
- Exact mechanism is unknown but may raise the brain’s
threshold for dealing with stimulation.
- Given to clients who have problems in lithium therapy
(SEs, drug interactions, renal disease)
- Carbamazepine, Valproic Acid, Clonazepam
Bipolar Disorder
Treatment
Psychotherapy
• Useful in the mildly depressive or normal
portion of the bipolar cycle. It is not useful
during acute manic stages because the person’s
attention span is brief and he or she can gain
little insight during times of accelerated
psychomotor activity.
