Depression Flashcards
What are risk factors for major depressive episode (MDE)?
Prior episodes depression, Family history
history of suicide attempts
pot partum, comorbid medical illmess, stressful life events, adverse childhood experiences
Active substance abuse
Females
Neuroticism
What are psyhological factors/theories contributing to MDE?
Psychodynamic theories (anger directed inward or disturbed infant-mother bond)
Interpersonal Theory (absent or unsatisfactory social bonds, lack social support)
Cognitive Theory (negative)
Learned Helplessness (always going to fail)
Discuss how the Dexamethasone Suppression Test works in a “normal” patient
Normally, giving Dexamethasone in a patient who is not having either Cushing’s Syndrome or Depression causes negative feedback onto glucocorticoid receptors in the Pituitary gland and decreases the release of ACTH and Cortisol and so patients have lower cortisol in response to Dexamethasone
How is the DST used in depressed patients? What other patients?
Depressed patients tend to have Hypercortisolemia that is not suppressed with Dexamethasone and these patients actually demonstrate higher post-dexamethasone cortisol levels (non-suppression)
Non-suppression is seen in severe, psychotic unipolar depression, major depression with suicide attempts, pts with family history of affective disorder, bipolar disorder and mania
What does DST non-suppression mean clinically?
NOT diagnostic since other psychiatric disorders are associated with it but correlates with higher rates of relapse
DST returns to normal within 1-3 weeks before clinical remission and reverst to non-suppression within 103 weeks of clinical relapse
How is the HPT axis involved in depression?
Thyroid disorders are found in 5-10% of people with depression
TSH is routine part of admission in labs
Thyroid hormones can be used as anti-depressant augmentation
What sleep patterns are seen in people with MDE?
Abnormal sleep is one of the most common symptoms
Changes include: delayed sleep onset, decreased sleep continuity (more waking), decreased REM latency, Longer first REM, abnormal Delta sleep (slow wave sleep)
Discuss MDD Epidemiology - men vs women, prevalence, other populations more at risk?
7% prevalence in US, prominent in 20 yos for first ddx
Women 1.5-3x higher prevalence than men
Higher in divorced patients than in married (especially men)
higher in Medically Ill patients
How do men and women experience MDD differently typically?
Women experience more sadness, worthlessness and excessive guilt
Men experience fatigue, irritability, anhedonia, and insomnia
What is the main part of the DSM5 criteria for MDD?
5 or more of the following symptoms most of the day, almost everyday, during the same 2 week period:
**At least one is either depressed mood or loss of interest/pleasure **
+
depressed mood, weight loss, insomnnia/hypersomnia, psychomotor retardation or agitation, fatigue, worthlessness/guilt, hard time thinking/concentrating
Suicide
NOT DUE to substance or other disorders and never had episodes of mania or hypomania
What is SIG-E-CAPS?
Suicide
Interest
Guilt
Energy
Concentration
Appetite
Psychomotor agitation/retardation
sleep
Compare and contrast grief vs a MDE?
Bereavement now recognized as a severe stressor that can precipitate the onset of MDE ; but with grieving dont see as much suicide or loss if interest (ex. woman loses her husband but still lights up when grandchildren come over)
Grief is more emptiness, decreases in intesnsity with time or comes in waves, people can still laugh, preoccupied with memories of deseased, self-esteem preserved, focus on “joining” the deceased
vs
MDE is persistent depressed mood, pervasive unhappiness and misery, self-critical and pessimistic, worthlessness and self-loathing, focused on ending ones own life bc undeserving or unable to cope with pain of depression
What qualifies as remission? what’s the bad part?
2 months without qualifying symptoms or with only 1-2 symptoms present to a mild degree
*Longer symptoms present then the harder that they are to treat so good to treat early on!!!
50% experience recurrence of MDE and each new episode increases risk for future recurrence and gets more severe
What are indicators for a greater chance of recurrence of MDE?
severe symptoms in recent episode
inadequate treatment
young age
persistence of mild symptom
high expressed emotion in the family
multiple prior episodes
marital problems
Psychotic problems, anxiety, co-morbid personality disorder
What are good prognostic indicators in MDD?
mild symptoms
no psychosis
advanced age at onset
no co-morbid psychiatric disorders
good social functioning for 5 years before symptoms onset
history of solid support system
