2 weeks
Depression is classified into two major types, what are they?
Exogenous
Endogenous
_________ depression is triggered by external stimuli, whereas _________ depression may or may not be related to external events
Exogenous
Endogenous
Prolonged grieving coupled with excessive guilt.
Pathological grief
What treatment modality is more effective to treat pathological grief?
Psychotherapy > drugs
Prolonged depression following failure or rejection. Common symptoms include hypersomnia and hyperphagia.
Adjustment disorder
What is the most effective treatment modality for treating adjustment disorder?
Psychotherapy > drugs
What are the two depression types within exogenous depression?
What treatment modality is best for exogenous depression?
Pathological grief
Adjustment disorder
Psychotherapy
What are the different depressive types within endogenous depression?
Major depression Severe depression Atypical depression Dysthymia Seasonal Affective Disorder Postpartum depression Bipolar disorder
Common symptoms include anhedonia and lack of response to positive stimuli. Symptoms are usually worse in the morning, and insomnia and weight loss are also typical.
Major depression
Similar symptoms to major depression with the addition of severe suicidal ideation and psychoses
Severe depression
The patient’s mood is regularly low but symptoms are not as severe as major depression.
Dysthymia
Mild or moderate symptoms of depression related to the lack of sunlight. Usually only affects people in the winter months.
Seasonal affective disorder
Alternating periods of elevated or irritable mood and periods of depression
Bipolar disorder
Moderate to severe depression in women after they given birth. Usually occurs within ___ months of delivery but may occur __ year after birth.
Postpartum depression
w/in 3 months - 1 year
Similar symptoms to major depression but patients also have the atypical symptoms of hypersomnia and hyperphagia. Patients are usually obese.
Atypical depression
This endogenous depressive type responds better to psychotherapy than drugs.
Dysthymia
Describe the major hypothesis for the biochemical basis of depression.
Monoamine hypothesis
States that altered monoamine release, receptor sensitivity, or postsynaptic function lead to symptoms of depression
Why is the efficacy of antidepressants difficult to assess?
Since it takes months for effects to occur
Results from placebo controlled CTs also suggests that as much as 40% of the effects of antidepressants may be due to the _______ ________.
placebo effect
Antidepressant drugs mediate their effects by one of two major mechanisms. What are they?
Inhibiting monoamine reuptake
Inhibiting monoamine metabolism
What are the four major classes of drugs used to treat depression?
TCAs
SSRIs
MAOIs
SSRIs/NSRIs
What is the mechanism of action of TCAs?
Prevent the reuptake of both serotonin and NE
What are the adverse effects of TCAs?
ASS WOD (Think TCA = techoic ass+ids [acids] —> ASS workout of the day)
Anticholinergic effects Sedation Orthostatic hypotension Decreased seizure threshold Cardiac toxicity Weight gain Sexual dysfunction
Describe the mechanism of action of SSRIs.
Block the reuptake of serotonin.
Why would SSRIs be used over TCAS if they only block serotonin, rather than serotonin and NE?
Thought to have similar efficacy to TCAs, but the incidence of side effects is lower
Most commonly used treatment of depression and most commonly used in major depression.
SSRIs
What are the adverse effects of SSRIs?
IWSS (i [don't] want Serotonin Syndrome) Insomnia Weight gain Sexual dysfunction Serotonin syndrome
Increased serotonin transmission can result in agitation, confusion, anxiety, hallucinations and incoordination.
Symptoms may occur within __ days of initial therapy and disappear when the drug is stopped.
Serotonin syndrome
3
Same mechanism of action as TCAs.
SNRIs - selective serotonin/NE reuptake inhibitors
What is the main advantage of SNRIs?
Faster onset of action
What are the adverse effects of SNRIs?
NDS (sNris –> Nintendo DS)
Nausea, diastolic HTN, sexual dysfunction
