  1. What causes Depression?
    Neurochemical changes + Negative thinking and attributional style
  2. Unipolar Depression stats on: % adults in US with severe for. % mild form. % adults exp an episode at least once. Who is more likely to suffer.
    • 9% suffer from severe depression. 
    • 5% suffer from mild depression.
    • 18% suffer from severe unipolar depression some point in living.
    • More likely: Poor, 40 YO, Woman 2x more likely than standard.
  3. Anhedonia
    inability to experience any pleasure. A symptom of depression
  4. % of people who suffer severe depression commit suicide?
    6-15%
  5. What's a major depressive episode?
    • period of 2 or more weeks with at least 5 symptoms of:
    • Depression, loss of pleasure, sad mood, and in extreme cases, delusions or hallucinations.
  6. What is Major Depressive Disorder?
    • Patient's gone through a MDE with no history of Mania. 
    • Categories:
    • Seasonal, Catatonic, peripartum, melancholic. If the patient gets a manic episode later on after the diagnosis, it can be changed to BIPOLAR DISORDER.
  7. What is Persistant Depressive Disorder?
    chronic unipolar depression, repeated MDE's- PDD with MDD. If less severe, PDD w/ Dysthymic syndrome
  8. Premenstrual dysphoric disorder
    woman who have clinically significant depressive and related symptoms during the week before menstruation
  9. Is all Major Depression Disorders Endogenic? T/F
    FALSE! Not all MDDs originate from the body. Most cases yes, but not all
  10. genetic causes of unipolar depression
    • Proband- person in a family with UD. 
    • Probands family has 30% higher rate of depression than general pop @ 10%.
    • TWINS: identical twins- other twin has 46% chance of UD.
    • Fraternal- 20%

    Due to abnormality in serotonin gene- low serotonin activity=depression dude.
  11. biochem causes of unipolar depression
    Low activity of NE and/or Serotonin. Overall imbalance of those mentioned and dopamine and acetylcholine.
  12. Why is Serotonin more important to the causes of unipolar depression?
    It's a neuromodulator, primary function is to increase or decrease activity of other neurotrans. if decrease, depression.
  13. Endocrine system affect on unipolar depression?
    High levels of cortisol from the adrenal glands during stress. Also, Melatonin "dracula hormone", released only in the dark.
  14. Brain anatomy relation to Unipolar depression?
    • Prefrontal cortex: functions with mood, attention, immune sys. lower blood flow here in depressed ppl. 
    • Hippocampus: neurogeneis- produces new neurons. depression decreases this. if treated w/ drugs, neurogenesis is restored. 
    • Amygdala: 50% more bloodflow here in depressed ppl. involved in expression of negative emotions + memories 
    • Brodmann Area 25: smaller in depressed ppl, but more active, may be a "depression switch".
  15. Psychodynamic view on unipolar depression
    • Freud + Abraham developed explanation for depression through: 
    • Symbolic/Imagined Loss- loss of a valued object thats unconciously interpreted as the loss of a loved one.

    This is abandoned, but Object relations theorists play off it and say parents that pushed ppl to excessive dependance or selfreliance are more likely to become depressed when faced with relationship issues

    Aka reactive depression. Result of a major loss.
  17. Behavioral view on Unipolar depression
    results from number of rewards + punishments received during life.
  18. Cognitive view on Unipolar depression
    • Aaron Beck believed:
    • depressed ppl persist with negative views on events.
    • Theory of negative thinking: maladaptive attitudes, cognitive triad, errors in thinking, automatic thoughts.
    • Learned Helplessness: developed by Seligman in 1975, 
    • depression brought on by feelings of loss of control and blaming of self on helplessness.
  19. What's the cognitive triad in the cognitive view of unipolar depression?
    Individuals repeatedly interpret 3 things in their life in negative ways. Experiences, Themselves, Futures.
  20. Sociocultural view on unipolar depression
    • triggered exogenically.
    • Family-social perspective:depressed ppl have bad social skills, cycle of socially failing + gettting more depressed. 

    • Multiculti Perspective: 2 relationships- Gender and depression-- Women 2x more likely for depression, but artifact theory says men + women are equal in development, but due to social norms, less detectable in men. hormone explanation says hormonse changes trigger it in women. Life stress theory women more subject to stress than men. Same w/ Body dissatisfaction theory. Lack of control theory says women are more prone b/ they feel less in control of their lives than men.
    • Rumination theory says if you focus on your feels when depressed, you get turned in a cycle of depression

    Cultural BG: every culture shares depressive symptoms.  but in US, hispanics + africans more 50% more likely to experience depression.
  21. When is someone considered to be in a Full Manic Episode?
    at least one week of display of abnormally high or irritable mood, increased activity and 3 other symptoms of mania, like overblown self esteem, reduced sleep, less inhibitions. May include psychotic features or delusions and hallucination.
  22. What is Bipolar I disorder?
    Full manic + depressive episodes. Most experience an alternation of these, for ex: weeks of mania followed by a period of wellness, then an episode of depression. Some have mixed features though, with mania + depression at the same episode.
  23. What's Bipolar II disorder?
    • hypomanic episodes alternate with MDE's. Some people with this can accomplish tons of work during the hypomanic periods. 
    • w/o treatment, the mood episodes recur.
  24. What is rapid cycling?
    If someone with Bipolar disorder has 4 or more episodes within a year.
  25. Which side of bipolar disorder is experienced more, and which disorder is more common? % adults suffering from bipolar disorder. % lifetime prevalence. Age of onset?
    • More common for depressive side, 3x more likely than manic eps. and they last longer. women experience more depressive eps with more rapid cycling. but overall its equal in prevalence for men and women.
    • % adults suffering: 1-2.6
    • % lifetime prevalence: 4
    • Age of onset is 15-44, most untreated cases the episodes subside, but recur eventually later on, and those with it get more medical complications.
  26. What is Cyclothymic disorder?
    numerous periods of hypomaic symptoms and mild depressive symptoms. Symptoms last 2 or more years with normal moods interrupting for a few days or a few weeks.
  27. Cyclothymic age of onset? Gender prevalence? % pop prevalence?
    Same age of onset at Bipolar I and II, in adolenscence or early adulthood. Equal in men and women. .4% of pop develops it. Eventually blossoms into Bipolar I or II.
  28. Old views on Causes of Bipolar disorder?
    psychodynamic theorists such as Lewin said mania and/or depression can emerge from the loss of a love object. introjection @ lost object=depression. deny loss=mania.
  29. Neurotransmitter cause of Bipolar disorder?
    Similar to depression, but low serotonin with high NE. May also be tied to abnormal activity of neurotransmitters such as GABA
  30. Ion Activity cause on Bipolar disorder?
    • Na and K ions
    • neurons firing too easily- mania
    • neurons firing not as easily- depression
  31. Brain structure cause on bipolar disorder?

    • Introjection of lost person. 
    • Suicide is the extreme experession of self hatred and self punishment.
    • Relationship between childhood losses = later suicidal behaviors:
    • Early parental loss- more common cause of suicide 48%
    • parental rejection or neglection leads to more than common too.

  36. Biological stance on Suicide Causation
    • Identical twins- 21% likely other twin committs
    • Frat/sibs/close relatives-  no correlation
    • Low serotonin- predictor of suicidal acts- 10x more likely to make a repeat attempt
    • Fewer receptor sites on neurons for serotonin, abnormal activity in prefrontal cortex, orbitofrontal cortex, cingulate cortex
    • Low serotinin- promote aggression and impulsive behaviors. Must be comined with other psychocoial factors to be seen as a strong predictor
  37. general Suicide prevalence in and Age groups
