Q

HPA axis

A

normal- stressor–>amygdala–> hypothalamus–> ant Pit–> Adrenal Glands–> cortisol–> hippocampus (glucocoritcoid receptor)–> stops production of CRH
Depressed- Cortisol toxicity damages FR’s in teh hippocampus and hypothalamus continues production of CRH failure of suppression of the HA axis

Q

treatment for MDD

A

pyschotherapy- talk therapies to help address symptoms
antidepressant drugs to help increase monoamines and serotonin levels( take 3-4 weeks to show effects, min duration of 6-12 months, slightly above placembo for mild and notable for moe severe)
ECT- electrical induction of a generalize seizure, pretreated with muscle relaxant and anesthetic to reduce consciousness- used to treat acute depression.
Transcranial magnetic Stimulation- magnetic pulses are generated and used to stimulate a patients cortex
Vagus Nerve Stimulation- intermittent electrical stimulation of the vagus nerve, FDA approved for treatment resistant MDD- risks of surgery implantation mild effects of stimulation.

17
Q

Antidepressants

A

SSRIs inhibits uptake of serotonin-
SNRI inhibits uptake of serotonin and norepinephrine
TCAs- Tricyclic antidepressants- Monoamine reputake inhibitors, have cardiac side effects(postural hypotension and tachycardia
MAOIs- monoamine oxidase inhibitors- diet restrictions to avoid tyramine induced hypertention

18
Q

Black box on ads

A

could cause suicide

19
Q

Serotonin syndrome

A

hyperthermia tachycardia, hypertension and delirium. ADs are switched without adequate washout period.

20
Q

MOA of ECT

A

multiple indiscrimante CNS effects, no mechanism identified, used with treatment resistant of depression, severe depression or preganant depressed.

21
Q

Contraindications of ECT

A

vascular disease, can cause initial side effects of cardiac arrhythmias, headache and confusion, some memory loss for recent long term memory and some encoding deicculties surrounding sessions

PMDD

A

present in the week before menses onset, improve a few days after mensesand minimized in the weeks post menses
-mood lability, irritability, dysphoria and anxiety symptoms
-anhedonia, problems concentration, lethargy, appetite and sleep change, physical symptoms. (breast tenderness and weight gain)

29
Q

Bipolar I Disorder (Manic Depression)

A

DC- must experience at least 1 Manic Episode

  • Most also experience MDE but not necessary for diagnosis
  • mean age of onset is 18,
  • mania usually occurs directly before MDE and lasts about 3 months
  • rule out another medical condition and substance intoxication
  • although the genes are unknown, BPI is highly heritable, more genetically controlled than MDD, Manic episodes involve increased monaminergic activity
30
Q

Manic Episode

A

abnormally elevated mood or irritability PLUS increased energy. Must have 3 symptoms.

  • inflated self esteem/grandiosity
  • decreased need for sleep
  • pressured speech
  • flight of ideas

31
Q

Bipolar Specifiers

A

mixed features- MDE symptoms occur throughout the same time period as mania
rapid cycling- patient experiences greater than 4 mood episodes/year
psychotic features- delusions or hallucinations are present

32
Q

  • doesn’t cause marked impairment.
  • change in mood must be unequivicoal and uncharacteristic of person.
  • hypomania must last at least 4 days
35
Q

Cyclothymic Disorder

A

DC: for greater than two years, a person experiences periods of hypomanic symptoms that fluctuate with periods of depressive symptoms

  • must not meet criteria for MDE. Similar to Bipolar I but the mood shifts are not as extreme.
  • can change diagnosis to BP I
  • Treatment- Mood stabilizers (as For BP I)
36
Q

Distinguishing Bipolar from Uniolar MDE’s

A

Bipolar disorders, MDE may be the patients first major mood episode prior to a manic or hypomanic episodes
-Because of treatment implications, it’s important to determine whether a MDE reflects MDD or a bipolar disorder.

37
Q

BP vs MDD

A

Family History-1.BP almost uniform, 2.MDD sometimes
First MDE episode less than 25- 1.Very common, 2. sometimes
MDE frequency- 1.Frequent 2. Less Frequent
MDE duration less than 3 months- 1.Suggestive 2 Unusual
Atypical Features- 1.Common 2. Occasional
EMAs and Insomnia- 1.More likely 2. Less Likely
Psychotic Features- 1.highly perdictive 2. Uncommon
Postpartum onset 1. Very Common 2. Sometimes
