Exam 2 Flashcards
Depressive disorders all share symptoms of
Sadness, loneliness, emptiness, irritability, somatic (body) concerns like back/neck pain, and impairment of thinking
All impact a person’s ability to function
Can get agitated or delusional
Disruptive mood dysregulation disorder
Children being diagnosed with bipolar, temper tantrums, violence, recognized this as a mood dysregulation. Predominantly seen in adolescents up to 18, less bipolar being diagnosed now
More of a childhood disorder
Persistent depressive disorder
Happens for years, symptoms are all the time
Can work, function, be social, have friends, but having a difficult time. Pure depression can’t do this
Dysthymic disorder
Premenstrual dysphoric disorder
More than physical changes like PMS
Uncomfortable in their own skin, feel better when menses starts (symptoms go)
Medication usually works for them
Substance-induced depressive disorder
Cocaine use makes you high, the opposite bottoms you out
Relaxants can make you depressed (alcohol)
Depressive disorders due to another medical condition
Open heart surgery makes you more likely to have depression (95%)
Parkinson’s, cancer, end-stage terminal illness like cardiac, respiratory, renal
Genetics and depression
37% incidence if a monozygotic twin is depressed, also genetic influences linked to earlier onset and recurrence
Biochemical etiology of depression
serotonin (affects mood, makes us feel good) and norepinephrine (behavior and attention, produced more when stressed, low in depression), dopamine, glutamate, acetylcholine
Hormones in depression
hypothalamic-pituitary-adrenocortical axis involvement
Inflammation in depression
c reactive protein and interleukin-6
Tests for depression (hormone)
Dexamethasone suppression test and high cortisol in urine tests for depression
Inflammation plays huge role in these illnesses, inflammatory biomarkers show this
Cognitive theory of depression
See a helpless situation, think helpless thoughts, world is hopeless, can’t get out of this circle (triad)
Changing negative thought and working it through to realize it’s not so bad (cognitive behavioral theory)
Learned helplessness
Happens when someone feels powerless over a situation, they learn to continue to function that way. If they’re stuck in traffic they don’t get over it
Patient health questionnaire
2 first questions ask about little interest in things. If yes, do you feel depressed and hopeless. If yes, automatically answer other 7 questions which are more serious like appetite or thoughts of hurting self, may be on constant observation. Med surg or other units ask the two questions. Psych unit uses Columbia screening tool
Assessment of depression
Questionnaire
Anergia
Anxiety
Psychomotor agitation or retardation
Vegetative signs
Chronic pain

Mental status exam
Affect
Thought process (can’t problem solve, memory and concentration problems, maybe delusional)
Mood/feelings (hopeless and helpless!!)
Communication (can’t get point across, don’t belong, inattention)
Hygiene and dress
Sleep habits
Bowel habits
Decreased libido from low serotonin and norepi

Recovery model with depression
Focus on patient’s strengths (have you ever experienced this before, gives idea of where they’re at)
Treatment goals mutually developed (patients need to be involved in meetings and treatment plan)
Based on patient’s personal needs and values
Planning
Phases of treatment and recovery
1.Acute– 6-12 weeks
2.Continuation–4-9 months
3.Maintenance–1 year and beyond
When do people w depression see improvement
Clinical benefits at least 1-3 weeks after initiation. Some people have response in 8-10 days but it’s usually 3 weeks which is a long time.
Trial of meds for depression
Adequate trial of meds is 6-9 months. Doctor says you need to stay on meds for 6-9 months even if you feel well after 3 weeks. Sometimes they get off the med or lower the dose after the 9 months, some eventually come off in 12 months. Some people stay on it
How are antidepressants chosen?
Family history, genetics, the Es of taking it (easy bc side effects, eat [watch what you eat])
Sometimes people are so used to being in depressive body state and the meds make you jittery and anxious and you stop taking them. Need to go through this to make you feel better. Not all meds do this though, but the ones that do are pretty severe
SSRIs
Selective serotonin reuptake inhibitors
First-line therapy
block uptake of serotonin so more is available at synapses, other indications such as OCD, and Panic Disorder
Came out third
SNRIs
Serotonin norepinephrine reuptake inhibitors
SSRIs may be tolerated better
Came out last
Tricyclic antidepressants
Anticholinergic adverse reactions
Came out in like ‘59
inhibit reuptake norepinephrine and serotonin (makes mood better)
