TCAs (tricyclics) - what is the main issue with them? (tricycles are lethal)

not really used anymore bc they have cardiac risks, endocrine risks, sexual side effects, and lethal if OD. used sometimes for migraines, amytripline. sometimes best for severe MDD; cardiac risk; frequently lethal if pt overdoses. know for test*****

MAOIs- what is the issue with them? (mao cheese)

not really used anymore, so many food drug interactions - tyramine reduced diet - smoked, aged, processed - meats, cheeses, sausage, red wine, ripe foods, chocolate. many food/drug interactions (fermented, smoked and cured foods are most dangerous); last med of choice.

SSRI/SNRIs- most common side effect, and what to watch for?

first line treatment; actions & SEs (side effects) more varied from med to med than with TCAs/MAOIs, but SEs generally milder and less dangerous; watch for serotonin syndrome (st. john’s wart and melatonin can cause it) anxious, flushed, cardiac, insomnia headache common at first. most common effect is sexual**in 50% of ppl.

Bupropion - what does it do?

inhibits dopamine uptake - so dopamine increases; unique among ADs in action (increases dopamine/norepinephrine) and potential SEs (decreased appetite, decreased desire to smoke, increased sexual desire). usually doesn’t develop until a month into treatment.

(basic talk therapy) is the oldest tx for MDD and is still effective most of the time, esp for mild-moderate depression

ECT (induction of a grand mal seizure)

half-second jolt produces about a 30 sec seizure - biggest risk is memory loss.

when is ECT used?

Used for drug-resistant and psychotic depression. ECT is rarely a permanent cure. Some pts benefit from maintenance ECT (monthly)

side effects of ECT

Short term memory loss is common and usually transient (warn both patient and family members about this). Re-orient patient and give NSAIDS/acetaminophen prn for HA (headache) and food bc they are NPO

ECT -how often are treatments, and how many?

Usually 6-12 treatments, given 2-3 times/week; can be done outpatient Safer to use in pregnancy than most ADs (anti-depressants), esp in 1st trimester Requires surgical permit and general pre- and post-op nursing care

TMS- how often is treatment, and for how long? (TMJ for 6 weeks)

basically uses MRI to stimulate the brain. Transcranial magnetic stimulation.Still uncommonly used. Non-invasive. Usual course is 5-30 min treatments for 6 weeks.

Bipolar I

(most severe one) – at least one episode of full mania, which is a psychotic state. Requires hospitalization

Bipolar II

(dysphoric or depressive, more depression) – at least one episode of hypomania (lesser form of mania), which is not a psychotic state, and at least one episode of severe depression.

Cyclothymia- and how long does it last?

hypomania alternating with minor depression for at least 2 years. (always treated outpatient)

mania is what state?

mania is a psychotic state

rapid cycling- how many times to consider it rapid?

if episodes happen 4 or more times a year, this is considered rapid cycling***sometimes they happen on the same day = this is called a mixed state. the quicker they fluctuate, the harder it is to treat.

S/Sx Bipolar I - men v. women

slightly more common among men, type 2 slightly more common among women

mania - Hyperactivity/sleeplessness

ask patient about their sleep - I’m worried you might get sick if you don’t sleep.

bipolar - Flight of ideas (bipolars fly)

racing thoughts, pressured speech used by client to relieve inner tension. you need to eventually interrupt them - I want to know more about…ask manic ppl about what brought to you the hospital?

bipolar - Grandiosity

delusions. thinks they are better than other ppl.

bipolar - words

Clang associations

bipolar 1 - Cognitive dysfunction is common with

mania (this is why CBT will NOT work during periods of mania. you can use it when they aren’t manic)

anosognsia

Resistance to tx

bipolar - Causative factors - genetics?

More genetic causation likely than with MDD (major depressive disorder) more in higher socioeconomic groups. Greater incidence in higher socioeconomic groups may be a result of BAD (II) rather than a cause

bipolar - treatments - Lithium and anticonvulsants take how long to work?

2-3 weeks to stabilize client (in the meantime, use benzos and atypical antipsychotics)

Lithium carbonate - what dose?

first drug of choice in United States. Remember: therapeutic range for acute mania is 0.6-1.5 mEq/L tx, can go as low as 0.4-1.2 mEq/L for maintenance.

Anticonvulsants- all can be used for what?

virtually all can be used for mood stabilization, although some are used off-label.

Atypical antipsychotics - what symptoms do they help?

(remember antipsychotics kick in right away) – Used frequently when a patient is manic to decrease agitation and help with sleep. All have mood stabilization properties. Most are now FDA approved as first line tx for mania and as an option for maintenance treatment.

Anxiolytics (benzos)

Important for anxiety, sleep and psychomotor agitation while mood stabilizers are taking effect. Lorazepam and clonazepam are drugs of choice.

bipolar - nursing treatment - ADL (what do they need the most?)

especially sleeping, PO intake and grooming.

bipolar - how to give instructions

Keep instructions firm, simple and brief.

bipolar - set limits

on abusive language and redirect as needed, but then ignore inappropriate verbalization (e.g. cursing at staff) as much as possible. sometimes you just have to ignore them. This behavior will diminish as meds take effect.

mood disorders - causative factors- hormones

Hormonal regulation - women most likely during adolescence, pituitary and hypothalamus issues.

mood disorders - causative factors- inflammation

Inflammatory processes - chronic inflammation, 1/3 have elevated c-reactive, and interlukins (cytokines), BDNF (miracle grow for the brain, helps neurons grow and reconnect) - low. exercise is best for BDNF.

mood disorders - causative factors- HIV

Immune dysfunction - HIV, not enough immunoglobulins.

causative factors- Cognitive (depression) rigidity

Cognitive rigidity - very common. black and white thinking. catastrophizing. validate first. Diathesis Stress Model - Trauma - childhood or anytime in life.

primary risk factors for depression (male or female?)

female, poverty, unmarried

meds - one of the first symptoms to start improving?

One of the 1st symptoms to improve is anergia.

meds - symptoms slower to resolve

Hopelessness and SI are slower to resolve. Starting doses in the elderly should be half the lowest adult dose

If a patient has a full-blown manic episode, s/he is

no longer BAD II. Instead, s/he is forever after diagnosed as BAD I.

hypomania- description - no what?

no grandiose delusions, no voices, a lot of energy but will sleep some.

bipolar causative factors - biological (hormones, etc)

Biological: hormonal changes, thyroid dysfunction (both hyper and hypo), circadian rhythm disruption, antidepressant use trigger, etc. sleep deprivation

signs of lithium toxicity?

if coarse tremor is visible at rest, it’s likely toxicity

common side effects of lithium

mild nausea & diarrhea,S/Es, which increase in toxic range, eventually leading to renal failure, seizures and death, thyroid, and cardiac. ***has a narrow therauptic range. renal failure is the main concern.

what labs to assess before starting lithium?

Renal/thyroid/cardiac functions need to be assessed before starting.

common anticonvulsant

VPA (valproic acid aka (Depakote)

valproic acid is good for which patients? (val is good for the mix)

good for mixed presentation or rapid cycling. is a first line treatment now in Europe and the US. Better than Li+ for rapid cyclers and mixed episode subtypes

primary risk factors for depression (gene)

history of loss or trauma, family history of depression, poor coping,

primary risk factors for depression - illness?

medical illness, chronic illness, isolated,

primary risk factors for depression

poor social support, substance use disorder.

signs of early lithium toxicity

muscle weakness and diahrrea

bipolar 1 - more common in women or men?

men

Dopamine (Decrease), Norepinephrine (Decrease), Serotonin (Decrease), Acetylcholine (Increase)

neurotransmitter - anxiety

Norepinephrine (Increase)

neurotransmitter - schiz/psychosis/mania

Dopamine (Increase), Norepinephrine (Increase)

neurotransmitter --Alzhemier’s Disease

A decrease in Acetylcholine

anhedonia

how often to assess for SI?

every shift, if that's what brought someone into the hospital
