Insomnia, sleep pattern changes, fatigue, irritable, can’t think clearly, suicidal thoughts - 1 episode of Mania - they will not have this diagnosis. (will be diagnosed with bipolar disorder).
- The earlier the onset, more likely it’s genetic. (if mother diagnosed at 45, more likely you’ll have it too. Rather than later age. The earlier diagnosed, the increased likelihood of reaccurances
- Women, twice as likelihood of getting MDD. (Reasons: women are more likely to report it,
Bereavement
*Previously in DSM 4 - (allowed 2 months of grieving)
- DSM 5 - if major depressive disorder symptoms of 2 months do not apply. (after a month even if caused by loss of a loved one, you will still be diagnosed with MDD
Mourning, grieving a loss of a loved one
Melancholic
- Depression tends to be worse in the morning
- Affects psychomotor functions (movement), moves a lot slower, loss of appetite, more likely to lose weight, excessive guilt
Psychotic Features
- Delusions (false beliefs) and hallucination (visual, auditory misperceptions)
Atypical Features
- Unusual, mood reactivity - they brightened with positive events. Mood will pick up and get better.
- Weight gain.
Catatonic Features
- Rigid, immobile, stuck in a position
With Seasonal Pattern
- Lack of sunlight, causes depression
- 2 or more depressive episodes in the past two years that vary according to the season.
- Treatment: light therapy - 30-90 minutes a day.
Depressive Disorder with Peripartum Onset (Previously, Postpartum depression)
- Major depressive disorder , but recent episode is during pregnancy or within 4 weeks of birth.
- Minimal family support / loved ones
Persistent Depressive Disorder
- New in DSM 5
- *2 years - more days than not.
- A mild form of depression
Premenstrual Dysphoric Disorder

- Mood swings, increased irritability/ anger, increased conflicts, more tension, depressed mood.
Disruptive Mood Dysregulation
- New in DSM 5
- Ages 6-18
- Severe recurrent temper tantrums, out of proportion to the situation.
- More diagnosed now
Genetic Causes - Depression
- Identical twins are twice as likely to suffer from depression compared to just siblings
Neurochemical Causes
Serotonin / Norepinephrine / Dopamine
- Too little of either 3 can cause depression.
- Hormonal factors
- Low thyroid function
Neurophysiological causes
- Damage in left lobe of prefrontal cortex of the brain - could cause depression.
- Lower brain activity in the left side of the brain.
Increased activation of the amygdala ( perceived though of threat ) - High blood pressure
- Early childhood trauma.
Psychoanalytic causes
- Unresolved unconscious issues from childhood.
Attachment Therapist causes
- Lack of attachment to a parent could cause depression.
- Learned helplessness - accepting the fact that your behavior will not change the outcome.
Cognitive causes
- Perceptions, the way you interpret the events.
Humanistic Theory causes

2-4% increase, (Improve energy level before improving the mood - may now act on suicidal thoughts) - more agitated
Electroconvulsive Therapy (ECT)
- still used in extreme cases, last resort, severely depressed
- 70-80% effective
- Chemical imbalances - tries to restore balance
Side effects: confusion, temporary amnesia,
Transcranial Magnetic Stimulation
- Magnetic foil over head, delivers electromagnetic pulse to the part of the brain that may be causing the depression
Deep Brain Stimulation
- *used for parkinsons, ocd
- Surgically implant electrodes into a specific part of the brain.
- Attached to a pacemaker, electrodes are released
BiPolar
- Fluctuation in mood. Up and down emotions
- Depression, mania, depression - fluctuates.
- Increase likelihood of substance abuse, diabetes, heart disease, anxiety disorder
- Causes: chemical imbalances, different parts of the brain abnormal,
- High Concordance Rate
- Treatment: mood stabilizer - works on depression and mania (Lithium/ Depakote)
Concordance Rate
- The chances you will develop the disorder given that someone in your family has the disorder. (Genetic)
- Is there a diagnosis for mania in DSM 5?
- No
- If you have mania -you have bipolar disorder
Mania
- Symptoms must last for 7 days
- Risky dangerous behavior, rapid speech, more irritable, impulsive, little need for sleep,
- False sense of well being (risky behavior)
Hypomania
- Lasts a minimum of 4 days (same symptoms as mania)
Rapid Cycler
- 4 or more cycles a year (depressive episode followed by a manic episode)
Bipolar I
- 7 days - full blown mania
- more serious - can cause hospitalization
- Alternates with symptoms of MDD
- Affects social functions, interpersonal, job
Bipolar II
- hypomanic episode 4 days
- Alternates with symptoms of MDD
- less severe - more common.
- Not as impulsive, better judgement,
Cyclothymic
- 2 years (3 or more cycles)
- A more mild form of bipolar disorder - more mild than bipolar II.
- Fluctuations of hypomania (mild) , depressive symptoms are mild.
