2. • T/F: 40% of people develop some type
of mental disorder in their lifetime
• Mental disorders
– 2nd
greatest contributor to shortened life
– source of significant human suffering
throughout the ages
• of patient
• of family
• of community
• Madness – lunacy – insanity
– thought by some
• to be a curse (and/or gift) from god(s)
• to be a source of criminality (moral insanity)
• to be a natural symptom of a sick society
3. • T/F: Only recently has mental illness become
viewed as disorder or disease (medical model).
• Benefits?
• Have natural causes
• Have symptoms
• Worthy of care
• (potentially) curable
Downsides?
4. what is abnormal?
• All mental disorders involve abnormal mental
states and behaviors.
– That is, they deviate in some way from the norm.
But, not all mental states/behaviors that deviate
from the norm should be considered mental
disorders.
With 40% of population developing disorder – what
is the norm and what isn’t?
– Szaz – The Myth Of Mental Illness
• Not a good definition (at least not by itself)
5. key elements of mental disorders
Mental states/behaviors that deviate from norms
AND
• Involves disturbances in behavior, thought, or
emotion
• Stems from internal dysfunction
– biological, psychological, both
6. Q: When is something a disturbance? When is
it a dysfunction?
• Involves significant personal distress or
impairment.
• What if the person isn’t distressed?
– e.g. Camille Claudel
– Historically, what has mattered more is other
people’s distress.

17. mood disorders
• Major depressive disorder
– Intense feelings of despair/helplessness, lethargy, gloom, lack of
interest, lack of pleasure
– 3-6 months in duration
– Categories: Melancholic, Psychotic, Catatonic
– Postpartum, Seasonal affective disorder
• Dysthymia
• Common factors involved in depression
– A) biological
– B) genetic
– C) psychological
– D) all of the above
18. contributors
• Biological factors
– Neurotransmitters – norepinephrine/serotonin
– Neurological processing of emotions
• Reduced activation in left dorsolateral PFC
• Increased activation in right dorsolateral PFC
• Problems with negative emotion regulation
• Psychological factors
– Helplessness theory
• Negative attributes/experiences
• Internal, stable, global
– Q: Does depression cause negative thoughts? Or do
negative thoughts cause depression?
19. analytic-rumination hypothesis
• “Pain or suffering of any kind…is well adapted to make a
creature guard itself against any great or sudden evil…leading
to the course of action which is most beneficial.” –Darwin
• Depression is like a fever that helps the immune
system fight off infection.
• Withdrawal from distractions
• Extended rumination about problem
– Hyperactivation of left ventolateral PFC leads to increased
analytic attention – intense, focused deliberation
• Negative moods lead to better decision making
20. analytic-rumination hypothesis
• Heightened creativity & problem-solving
– artists/writers/philosophers 8x more likely to suffer from
depression
– depression intertwined with creative “cognitive style”
– persistence, obsessive/relentless focus
• “Unfortunately, this type of thinking is often
inseparable from the suffering…If you’re on the
cutting edge, then you’re going to bleed.”
– Nancy Andreasen, neuroscientist
• Problems with this view?
22. dissociative disorders
• Loss or fragmentation of “self”
– Cognition, emotion, perception, memory
• Coping mechanism for traumatic events
• Depersonalization disorder
– Feeling of disconnection from self; unreality
• Dissociative amnesia
– Impairment of recall resulting from emotional trauma
– Retrograde vs. anterograde amnesia
• Dissociative fugue
– Impaired recall of past, abandonment of past
– Assumption of new identity
23. • Dissociative identity disorder
– T/F: Same thing as multiple personality disorder

– Delusions
– Disorganized speech, thinking, and behavior
• Onset typically occurs in young adulthood
• Contributory factors
– Genetics
– Neurobiology: increased dopamine
• Reduction in brain mass (5-10% over a decade)
– Early environment (trauma)
25. • Subtypes of schizophrenia
• Paranoid
– Delusions, hallucinations
• Catatonic
– Stupor or disorganized, purposeless behavior
• Disorganized
– Thought disorder, flat affect

28. Personality disorders
• Antisocial personality disorder
– "...a pervasive pattern of disregard for, and violation of, the rights of
others that begins in childhood or early adolescence and continues
into adulthood."[
– history of conduct disorder
– sociopath and psychopath
– one study of 22,790 prisoners
• 47% of men and 21% of women were diagnosed with
APD
– less activity in amygdala and hippocampus to
words that elicit fear in non-APD
29. Behavioral markers
• Even though antisocial personality disorder
cannot be diagnosed before adulthood, the
presence of three behavioral markers, known
as the Macdonald triad, can be found in some
children who go on to develop ASPD.
– Bedwetting
– Abuse of animals
– Pyromania
30. Diagnosis

indicated by repeatedly performing acts that are grounds for arrest;

– Impulsivity or failure to plan ahead;
– Irritability and aggressiveness, as indicated by repeated physical fights
or assaults;
– Reckless disregard for safety of self or others;

• Substance abuse
• Aggressive, often violent behavior; prone to getting involved in fights
• Inability to tolerate boredom
• Disregard for the safety of self or others

authority figures.
