abnormality is….
a continuum!
list
Stereotypes/Misconceptions of Abnormality
there’s 3!

Who is..
Dorthea Dix
She pioneered the Moral Movement, which promoted using more ethical + humane methods of treatment
Describe
Modern Day
medicine was introduced, leading to desinstitutionalization
that word is long
List
Issues with Diagnoses
3!
- Can justify people’s behavior, making them feel like they have no control
- Can be modeled to suit political, social, and business goals
- Can let others benefit (pharma, psychiatrists, etc.)
List
Pros of Diagnoses
4!
- Helps guide treatment choices
- Allows clinicians to communicate
- Pleases insurance companies that require concrete diagnosis
- Aids/permits research by providing categorizations
List
Misconceptions about Diagnoses
theres quatre
- Pyschiatric diagnoses are just for sorting people into boxes
- Pyschiatric diagnoses are unreliable
- Pyschiatric diagnoses are invalid
- Pyschiatric diagnoses stigmatize people
What is used to diagnose mental disorgers?
DSM-5
diagnostic and statistical manual of mental disorders
What does the DSM do?
two thingies
- provides a list of diagnostic criteria for each condition
- provides a set of decision rules to decide how many criteria must be met
describe
Criticisms of DSM
- assumes people can be reliably placed into non-overlapping categories
- reliance on a categorical model
movement is being made towards a dimensional model
define
Comorbidity
co-occurence of two or more disorders in one person
List

List
Factors influencing Depression
6 (5 lecture, one textbook)
- Genetic vulnerability
- Biological/Neurochemical Mechanisms
- Cognitive Factors
- Interpersonal Factors
- Stress
- Behavioral Factors
Describe
Genetic Vulnerability
depression
if one identical twin has depression, 65% chance the other one does (compared to 14% in fraternal)
-> genes predispose people, gene x environment interaction
Describe
Biological/Neurochemical Mechanisms
depression
- abnormal levels of serotonin, norepinephrine, and dopamine
- Decreased hippocampal volume
- lack of serotonin may lead to neurogenesis supression
describe
Cognitive Factors
depression
- Negative cognitive triad: self, world, future
- negative mental spin on life, inaccurate perceptions lead to depression and vice versa
- learned helplessness
- Ideal affect
ideal affect: difference between how we feel vs how we want to feel
e
What does learned helplessness lead to?
- attributing failures to internal factors
- attributing successes to external factors
Describe
Interpersonal Factors
Depression
- shrinking social circle, less social skills
- assortative mating
Describe
Stress
depression
- major life events
- loss of a loved one, self worth, financial stuff, health
Describe
Behavioral factors
Depression
people try things and recieve no payoff, leading them to giving up
Why are there gender differences in who experiences MDD?
10-25% of women vs 5-12% of men
MDD = Major Depressive Disorder
- differences in physiology
- men are more reluctant to seek treatment, see depression as a weakness
- alchoholism is higher in men - it masks depression and can be used as self medication
- Gender specific social factors and trauma
list
Major Risks of Depression
3
- suicide
- physical illness
- decreasing social functions
How long does MDD last?
Depression is recurrent, sometimes chronic. People tend to have 5-6 episodes lasting 6 months to a year on average
Describe
Seasonal Affective Disorder
Form of depression that follows a seasonal pattern + is linked to circadian rhythm
Treatment: time with bright lamp 15-30 min per day, exercise, get good sleep
What is Bipolar I characterized by?
one or more manic and depressive episodes
List
DSM-5 Criteria for Bipolar I
there’s 3!
A. At least one manic episode
B. Symptoms cause distress and/or impairment
C. Symptoms are not better described by schizophrenia disorders
Describe
Manic Episode
Period of abnormally and persistently elevated mood
- inflated self-esteem
- decreased need for sleep
- more talkative
- flight of ideas
- distractibility
- goal directed activity
- risk taking behavior
Symptoms are sufficient enough to cause impairment, hospitzlization, and may have psychotic features
`
List
DSM-5 Criteria for Bipolar II
A. at least one hypomanic and one depressive episode
- symptoms last for at least four days
- does not impair functioning
- does not require hospitalization
- no psychosis
B. There has never been a manic or mixed episoe
Define
Rapid Cycling
four mood changes in a year
Describe
Mixed Episode
Symptoms of mania and depression coexisting
True or False: Mixed episodes are dangerous
True! depressive thoughts coexisting with manic energy creates a high suicide risk
Describe
Cyclothymia
moods alternating between hypomanic and depressive symptoms over two years, no full blown episodes
Who gets sick?
bipolar
- 1% of the population
- strong genetic correlations
- onset around 18-22 years
Why is bipolar so dangerous?
- often has comorbidities with other issues, both mental and physical
- drugs don’t help with depressive episodes, so people will skip out taking them to experience hypomania
describe
Panic Disorder

- overthinking, irratonal anxiety, hard time letting go of worries, etc
Biological influences
anxiety disorders
- genes influence levels of neuroticism, impacts anxiety pronenes
- OCD is correlated with abnormalities in white matter and increased activity in frontal lobes
Other aspects of anxiety
im sorry its a bad prompt idk how to classify these
- catastrophizing

this can also be a side effect of meds and nstitutionalization
define
Diathesis-Stress Models of Schizophrenia
schizophrenia is a joint product of genetic vulnerability and a stressor that triggers it
Discuss
The Brain and Schizophrenia
reduced brain volume and increased ventricular space
correlation, not causation!
