The goal of cognitive-behavioral therapy with major depression disorder is to...
Change the way clients think by assisting client in:
1. identifying and testing negative conditions
2. developing alternative thinking patterns
3. rehearsing new cognitive and behavioral responses
Describe the 3 phases in the treatment and recovery from major depression
1. ACUTE (6-12 weeks) reduction of symptoms and restoration of ADLs
2. CONTINUATION (4 - 9 mos.) prevention of relapse through pharmacology, education and psychotherapy
3. MAINTENANCE (1 or more years) prevention of further episodes of depression
Name the 3 first line psychopharmacological/somatic treatments for MMD

2. New atypical antidepressants
3. Cyclic antidepressants (tricyclic antidepressants)
Name the 2 second line psychopharmacological/somatic treatments for MMD
1. Monoamine oxidase inhibitors (MAOIs)
2. Electroconvulsive therapy (ECT)
What does serotonin do in the body?
In the CNS, serotonin plays an important role in the regulation of anger, aggression, body temperature, mood, sleep, vomiting, sexuality, and appetite. Low levels of serotonin have been associated with several disorders, namely increase in aggressive and angry behaviors, clinical depression, Obsessive-compulsive disorder (OCD), migraine, irritable bowel syndrome, tinnitus, fibromyalgia, bipolar disorder, and anxiety disorders.
What do serotonin reuptake inhibitors do?
Increases the levels of serotonin in the body by preventing the reuptake process, leaving serotonin to act for an extended period at the synaptic binding sites in the brain.
What conditions are SSRIs used as the first-line therapy?
All types of depression EXCEPT 1)psychotic depression (ECT first choice), 2) melancholic depression and mild depression
What are the side effects of SSRIs
*N/V, weight gain
*insomnia, anxiety, decr. sex drive
*anticholinergic s/e: dry mouth, blurred vision, urinary retention
* serotonin syndrome (rare--client goes into shock)
Describe serotonin syndrome
Extremely high levels of serotonin can have toxic and potentially fatal effects, causing a condition known as serotonin syndrome. In practice, such toxic levels are essentially impossible to reach through an overdose of a single anti-depressant drug, but require a combination of serotonergic agents, such as an SSRI with an MAOI.
What important things to include in SSRI patient teaching
1. can take 1-4 weeks to take full effect
2. side effects (weight gain, sex drive, dry mouth, tremor, lethargy, etc)
3. serotonin syndrome
4. no alcohol & otc drugs
5. don't stop suddenly
Why are SSRIs the best first-line therapy?
less side effects so patients more likely to comply with medication regimen
What are the symptoms of serotonin syndrome?
abdominal pain, diarrhea, sweating, fever, tachycardia, hypertension,delirum, muscle spasms, cardiovascular shock
What are emergency interventions should be taken
1. remove offending agent
2. initiate symptomatic treatment (serotonin receptor blockade, cooling blankets, etc)
What do Tricyclic Antidepressants do?
Tricyclic Antidepressants inhibit the reuptake of norepinephrine and serotonin by the presnaptic neruons in the CNS (increasing the amount of time that they are available to the post synaptic receptors).
Nursing implications/ Teaching about tricyclic antidepressants should include
1. full effects may not be seen for 4 - 8 weeks
2. Low dosage given initially--increased slowly
3. s/e like anticholinergic drugs (dry mouth, blurred vision, tachycardia, constipation, urinary retention, postural hypotension)
3. urinary retention and severe constipation warrant immediate attention
4. Give at night
5. potential toxic side effects are cardiovascular
6. alcohol blocks effect of drug
7. do not double dose of missed doses
8. taper off
Drugs to use with caution when taking TCA
