mood states
- euthymia
- feeling sad/upset/grief
- major depressive episode
- dysthymia
- hypomania/hypomanic personality
- mania
euthymia
- the goal of treatment aka living without mood disturbances and achieving baseline again
hypomanic personality
individuals are extroverted, energetic, intensely emotional, hyper confident, ambitious, impulsive, need less sleep and tend to be rude, irritable and irresponsible
polarity of mood states
- average length of tome for the first untreated major depressive episode is 9 months
- treated MDE = 4-5 months
- untreated manic episode lasts between 2-6 months but will often be noted well before
major depressive episode
- a component of various mood disorders
- must experience 5 or more symptoms out of 9, during the same two-week period
- at least 1/5 symptoms experienced must be either depressed mood or anhedonia
major depressive episode symptoms
- depressed mood
- significantly diminished interest or pleasure in all activities
- significant weight loss or gain
- insomnia or hypersomnia
- psychomotor agitation or retardation
- fatigue/loss of energy
- feeling worthlessness or guilt
- diminished ability to think or concentrate
- recurrent thoughts of death, suicidal ideation or suicide attempt
major depressive disorder criteria
- one or more MDE (must be at least 2 months symptom free between episodes)
- cannot be a normal response to a significant loss
- no history of mania/hypomania
- women are more likely to be diagnosed then men
- age of onset is high in early puberty to late twenties
- 12mo% = 5-8%
- life% = 10-20%
persistent depressive disorder (dysthymia)
- individual experiences depressed mood for most of the day, nearly every day, for 2 years
- incredibly chronic
- no history of mania/hypomania
- can not be symptoms free for more than 2 months to receive a diagnosis
- can have MDE and still have PDD but if both are experienced simultaneously it is called double depression
- women are twice as likely as men to be diagnosed
- onset can start in childhood but is typically in early adulthood
- 12mo% = 1%
- life% = 2-5%
PDD symptoms
- 2/6 symptoms needed to receive a diagnosis on top of a depressed mood:
1. poor appetite or overeating
2. insomnia or hypersomnia
3. low energy or fatigue
4. low self-esteem
5. poor concentration or difficulty making decisions
6. feelings of hopelessness
manic episode
- a 1 week period of significantly elevated, expansive, or irritable mood, and significantly increased goal-directed activity or energy
- one week period doesn’t apply if they have been hospitalized
- commonly leads to hospitalization
- involve hallucinations or delusions
mania criteria
- additional symptoms; need 3/7 or 4/7 if the primary presentation is the irritable component:
1. inflated self-esteem or grandiosity
2. decreased need for sleep
3. more talkative than usual or pressure to keep talking
4. flight of ideas
5. distractibility
6. increased goal-directed activity or psychomotor agitation
7. excessive involvement in risky behaviour
hypomania episode
- identical to a manic episode, except for the following differences:
1. typically shorter in duration, but must last at least 4 days
2. not severe enough to cause hospitalization
3. no significant impairment in daily functioning
bipolar 1 disorder
- has had a manic episode
- highly recurrent
- people will bipolar 1 have more hypomanic episodes then bipolar 2
- often begins with a major depressive episode
- rates are equal between men and women
- average age of onset for the first manic episode is 18
- 12mo% = 0.6%
- life% - 1%
bipolar 2 disorder
- has has a hypomanic episode
- has had a major depressive episode
- no history of mania
- people with bipolar 2 have more total mood episodes then people with bipolar one
- equal in men and women
- average age of onset is mid 20s
12mo% = 0.6-0.8% - life% = 1%
cyclothymic disorder
- numerous periods of hypomanic symptoms and numerous periods of depressive symptoms for 2 years
- can not been without symptoms for more than 2 months
- no history of mania, hypomania, or major depressive episode
- half of people with cyclothymia will go on to develop a bipolar disorder
- rates are equal between men and women
- age of onset is typically adolescents or early adulthood
- 12mo% = 0.3-0.5%
- life% = 0.4-1%
mood disorder specifiers
- psychotic features (hallucination/delusions)
- melancholic features anhedonia, guilt)
- atypical features (overeating, oversleeping)
- peripartum (before/after giving birth)
- seasonal pattern
- rapid cycling ( 4 episodes in 12 mo)
etiology - biological approaches
- genetics
- behavioural activation system (BAS)
- neurotransmitters
- sleep
genetics - etiology
- tends to run in families, especially in twins
- more recurrent in families
- BPD tends to be stronger in families (passed on)
BAS - etiology
- sensitivity to rewards and motivation
- positive emotions and hope
- linked to dopamine
- individuals can have a global reaction to activity happening in the environment (i.e. finding things rewarding or less sensitized); this occurs by getting a signals from the environment that something may be rewarding
- designed to increase our contact with positively rewarding activities
neurotransmitters - etiology
- low levels of serotonin; allowed norepinephrine and dopamine to range wildly
- serotonin helps achieve homeostasis
sleep - etiology
sleep disruptions may lead to depression or mania
mood disorders etiology - biological approaches
- tricyclic antidepressants
- monoamine oxidase inhibitors (MAOIs)
- selective serotonin reuptake inhibitors (SSRIs)
- mood stabilizers
tricyclic antidepressants - mood disorder etiology
- increase the amount of norepinephrine and serotonin in synaptic cleft so they get more reuptake for overtime effects
- can be lethal if overdosed
MAOIs - mood disorder etiology
- increase the amount of norepinephrine, serotonin and dopamine
- lots of dietary precautions and risks of severe reactions if mixed with other drugs
- used less frequently than SSRIs
