Premenstrual Dysphoric Disorder
- cluster of symptoms that occur in the last week prior to the onset of woman’s period
- s/s = physical discomfort, emotional symptoms similar to major depression and may interfere with the woman’s ability to work or interact with others
- symptoms decrease or disappear with the once of menstruation
- 2.5-5.5% of women have this
Substance Abuse Depressive Disorder

- would not experience these symptoms without drugs/alcohol use or withdrawal
Depressive Disorder Associated with Another Medical Condition
- result of changes that are directly related to certain illnesses such as kidney failure, parkinson’s disease, alzheimer’s disease or use of medications
- not considered major depressive disorder
Etiology of depression
- leading cause of disability in the united states
- comorbidity: can be associated with other medical conditions
- as you age it is not normal, but more prevalant, to have depression
- older men > depression
- younger women > depression
- 2x more common in women that in men
- diathesis-stress model apply
Depression Assessment
- 15% of people with depression will commit suicide
- Assessment tools: Beck depression inventory, hamilton depression scale, zung depression scale, geriatric depression scale, PHQ-9 (diagnoses depression 91% of time, used at each visit to assess pts, easiest)
- Assessment of suicide potential: increased risk with severe hopelessness, overuse of alcohol, recent loss or separation, history of suicide attempts, actual suicidal ideation. evaluate at each visit
- Key assessment findings: depressed mood and anhedonia are key symptoms, anergia (no energy), anxiety (60-90%), psychomotor agitation (constant pacing), psychomotor retardation (very slow movements). somatic complaints (headaches, malaise), vegetative signs (change in bowels, eating, sleep, sex), pain
- Mood and affect: Affect = outward representation of a person’s internal state of being, posture is poor, may look older than age, frequent bouts of weeping, face looks sad, hopeless, despair, no eye contact, monotone speech, flat affect, short responses, frequent sighing. Mood = pt’s subjective experience of sustained emotions or feelings, can only be assessed by asking the pt what they feel
- Psychomotor retardation and agitation: retardation = lethargy and fatigue lead to movements that are extremely slow, facial expressions decreased, gaze is fixed. agitation = constantly pacing, bite nails, smoke, tension-relieveing activities, fidgety, unable to relax
- Special considerations in children and elderly: children = depression is often overloooked with children, 18% of children have issues, sadness and lack of pleasure, withdrawn, irritable, negativity, isolation, loss of energy, withdraw, substance abuse. elderly = often overlooked, geriatric depression scale
affect
- flat = no expression at all, emotionless
- blunted = significant reduction in intensity of emotions
- inappropriate = doesn’t match situation
- labile = abnormal variation in affect with repeated, rapid and abrupt shifts in affective expression
Depression Nursing Diagnosis
Priority diagnoses:
- risk for suicide = always highest priority is safety
- hopelessness
- ineffective coping
- social isolation
- spiritual distress
- self-care deficit
Depression Planning
- outcomes: acute and long term outcomes should be identified, SMART goals
- Recovery: recovery model emphasizes healing is possible for all pts. attained through partnerships between patients and healthcare providers who focus on patients strengths.
3 phases of Depression treatment
- 3 phases in treatment and recovery from major depression:
1) acute phase: 6-12 weeks, directed at reduction of depressive symptoms and restoration of psychosocial and work function. hospitalization may be required and meds may be started
2) continuation phase: 4-9 months, directed at prevention of relapse through pharmacology, education and depression-specific psychotherapy
3) maintenance phase: 1yr or more, directed at prevention of further episodes of depression. meds may be phased out or continued
Depression nursing interventions
- communication: just sit with patients, silence can be the best communication, make observations, simple/concrete words, allow time for pt to respond, avoid platitudes (things will look up)
- Health teaching and promotion: health teaching is most important, allow pts to make
- promotion of self-care activities: physical neglect can come with depression
- teamwork and safety: milieu therapy, precautions, restraints
SSRIs
- exp: celexa, lexapro, prozac, paxil, zoloft
- block
- first line therapy
- mild depression
- decreased side effects
- faster than tricyclics
- patient compliance is better
- serious side effects: central serotonin syndrome (and pain, diarrhea, sweaty, fever, tacky, increased BP, altered mental state), increased SE when given with MAOIs
- periactin: given to help with CSS
- sansert: given for CSS
- propanolol: beta blockker used to decrease BP
- use cooling blanket
Tricyclic (TCA’s)
- exp: elavil, amozapine, clomipramine
- inhibit norepi and serotonin increasing the mat of norepi and serotonin available
- side effects: anticholinergic effects, heart dysrhythmias, MI, heart block, tacky
- adverse rxn: MAOIs (14 day washout period), alcohol, bentos, phenothiazines, barbituates, antibuse, BC, anticoags
- contas: recent MI, narrow angle glaucoma, seizures, pregnancy
- lethal if overdosed
- neurotransmitter effects
- start with low doses then increase
- can take 1-3 weeks to work
MAOIs
- exp: isocarboxazid (marplan), phenelzine (nardil), selegiine, parnate
- increases neurotransmitters at synaptic gap
- indicaitons: atypical depression
- adverse effects: don’t mix with other drugs, don’t eat tyramine, give in morning (insomnia), ortho hypo, weight gain, edema, constipation, mania
- contras: CVA, CHF, HTN, liver disease (tyramine), surgery 10-14 days, less than 16 yrs
ECT
- electroconvulsive therapy
- emergency tx, rapid response needed to prevent suicide
- informed consent needed, just like surgery
- SE: confusion, disorientation, short term memory loss
- typically 3 X week for 3-6 weeks
- given sedation, paralytic, EEG monitoring
- Goal: give them a seizure, do not give bentos or anti seizure meds
light therapy
- evidence-based
- seasonal effective disorder
- light on face 30 mins/day
- helps regulate melatonin
St John’s wort
- thought to increase saratonin, norepi, and dopamine
- mild-moderate depression
- mild MAOI effects, can increase CSS, hypertensive crisis
exercise and depression
- effective for mild depression, can act like an SSRI
cognitive behavioral thearpy & interpersonal therapy
