Notes Unit XII Modules 65-69
Module 65 Introduction to Psychological Disorders
World Health Organization (WHO) says 450 mill people have mental disorders
Depression/Schizophrenia are very common.
“Appear more consistently rates of disorders vary by culture.”
Defining Psych Disorders:
A disorder- is a syndrome marked by clinically significant disturbances in an individual’s cognition, emotion regulation, or behavior.
Maladaptive-
Disturbed or dysfunctional
Interferes with normal day to day life.
Controversy- disorders are sometimes dependent on culture.
Mental disorders determination or diagnosis are subjective example homosexuality was a disorder till 1973. Today we think of HDHD in similar terms…
Understanding Psychological Disorders p. 651
Early treatment and understanding was attributed to super natural forces.
Treatment was abusive, beatings, burning, castration, dunking in cold water etc…
The Medical Model:
Philippe Pinel died 1820’s
Reformer in France
Started reforms in hospitals
Argued “abnormal behavior is disease of the mind.”
Moral Treatment
1. Boost morale
2. Treatment is more humane
3. Gentle
4. Activity vs. Isolation
5. Clean air/sunshine
Today we use the Mental Model
Mental Illness = psychopathology
Includes:
Mental Illness
Diagnosis
Symptoms
Treatment/Therapy
Hospitals
Biopsychosocial Approach
Nature-Genetic and Physiological causes
Nurture- Experience/conditioning/social factors
Culture and Mental Illness
Cultural issues relate, for example Anorexia/bulimia are found in Western cultures.
Running Amok- in Malesia
Susto- Latin America, severe anxiety, restlessness, fear of black magic.
Taijin- Kyofusho- social anxiety, fear of eye contact
Hikikomori (Japan) extreme withdrawal
Classifying Psychological Disorders
Classification-
DSM-5 Organizes and describes Symptoms
Diagnostic Criteria for mental disorders
Defines criteria= frequency, causes, duration, multiple symptoms, treatment options
Example Insomnia Disorders
Revisions are made regularly
Bias and Labeling Psychological Disorders
Labels- problem when a label is given it creates expectancy and preconceptions
Preconceptions guide our perceptions and attitudes. We judge and change our behavior when we get information, also creates prejudice
Experiment-Bias of Labels
Rosenhan 1973
Patients misdiagnosed with mental disorder were held 19 days
Stereotypes were reinforced.
Rates of Psychological Disorders P 657
1. US + Ukraine highest
2. Nigeria, Italy, Shanghai least
P 658
1. Predictor of mental disorder
- Poverty correlation
- Poverty can have an exacerbating effect
Onset of Mental Disorders
1. Usually in early adulthood for most disorders manifest mostly by age 24
2. Antisocial Personality Disorder and phobias emerge ages 8-10
3. Alcohol use Disorder – emerges around age 20
4. OCD, Bipolar, Schizophrenia, and Major Depression- all emerge around age 25.
Module 66 Anxiety Disorders, Obsessive-Compulsive Disorder, and Post-traumatic Stress Disorder
Often caused by fear of future loss.
Anxiety
· Uneasiness
· Tense- intense dread/fear
· Distressing
· Persistent Anxiety
· Dysfunctional anxiety reducing behavior (maladaptive coping behaviors of drugs and alcohol)
Generalized Anxiety
· Unexplained
· Continual
· Tense and uneasy
Panic Disorder
· Sudden episodes
· Creates intense dread
Phobias
· Intense
· Irrationally afraid of specific object or situation
Obsessive Compulsive Disorder
· Repetitive thoughts or actions
Post-Traumatic Stress Disorder
· Lingering memories
· Nightmares
· For weeks
· Uncontrollable
Generalized Anxiety
· Unfocused
· Out of control
· Agitated feelings
· Pathological worry
· Persistence 6 months or more
· 2/3 are women
· Jittery/agitated
· Sleep deprived
· Cause many not be easily identified
· Also with depressed mood
· High blood pressure
· Childhood causes- maltreatment,
· By age 50 relatively rare
P 662
Panic Disorder (Anxiety)
· Panic attack
· Physical manifestations
· Heart beat
· Shortness of breath
· Choking sensation
· Trembling
· Dizziness
Phobias
· (Anxiety disorder)
· Irrational fear
· Causes person to avoid 1. Object 2. Activity 3. Situation
Social Anxiety Disorder
· Shyness to an extreme
· Fear of being scrutinized by others
· Worries about anxiety
Agoraphobia
· Fear or avoidance of public crowds/public situations
Obsessive Compulsive Disorder
· Being obsessed with thoughts that will not go away
· Maladaptive
· 2/3 %
· Often @ late teens
· Young people and adults
Post-Traumatic Stress Disorder
· 250,000 US Vets have been diagnosed with PTSD or Traumatic Brain Injury
· Characterized by
· Emotional traumatic experiences
· Social Withdrawal
· Nightmares
· Jumpy anxiety
· Insomnia
· 1 in 6 people in combat report either PTSD/Depression/severe anxiety
Brain Areas
· Amygdala- emotion
· Temporal lobe = memory
· Genetic predisposition
Resiliency- lots of people don’t experience PTSD even with lots of trauma
Understanding Anxiety Disorders
Learning/Conditioning
Conditioned fear through Classical and Operant conditioning
People become hyper-attentive to threats
They associate anxiety with certain cues/stimuli
· Stimulus generalization
· Reinforcement
· Avoidance
· Observational learning
· We learn fear through observing others in fear
o Monkeys and fear of snakes
Cognition
· Irrational beliefs
· Hyper vigilance
· Intrusive thoughts
Biological Perspective
- Evolutionary/Genetic
2. Anxiety genes
3. Coping genes
4. Neurotransmitters
- Serotonin (related to genes)
- Glutamate - too much = anxiety
The Brain and Anxiety
“As an over arousal of brain areas involved in impulse control and habitual behaviors.”
· OCD
· Anterior cingulate cortex
· Region monitors our actions and checks for errors
· Is hyperactive
· Frontal lobe
Module 67 Mood disorders p 671
Definition of Mood Disorders
Psych disorders characterized by emotional extremes
Two major types of Mood Disorders:
Major Depressive Disorder
Prolonged hopelessnessLethargy
Depressive symptoms:
Feeling deeply discouraged about the future
Dissatisfied with life
Feeling socially isolated
Lack energy to get things done
May not have energy to get out of bed
May be unable to concentrate, eat, sleep,
Thoughts of suicide
Social Stresses
Often caused by a response to past and current loss, death, marital disruption, lost job…
Ruminative thinking /
Bipolar Disorder (less common than depression)
Formerly called Manic DepressiveA person alternates between depression and mania (an overexcited, hyperactive state, euphoric, hyperactive, wildly optimistic)
Alternating between depression and mania week to week (not day to day)
· Issue of lots of diagnosis for adolescent boys. Which will be remedied by new classification
During Manic Phase:
Overtalkative
Overactive
Elated
Have little need for sleep
Show less sexual inhibitions
Reckless/poor judgment
(some connection of mania to creativity)
Famous Bi-polar:
Fredric Handel, Schuman,
Composers, artists, poets, novelists, and entertainers seem especially prone
Mania is followed by depressive episode
Depression is the number one reason people seek mental health services
Stats say, depression is affects 17% of US adults.
Depressive Episode plagues 5.8% of men and 9.5% if women
Depression as an evolutionary interpretation-
“it protects the psyche. It slows us down, defuses aggression, helps us let go of unattainable goals, and restrains risk taking…”
“Redirects energy in more promising ways”
Persistent Depressive Disorder (AKA dysthymia)
Characteristics:
Mildly depressed mood more often than not, for a least 2 years.
Also at least two of the following symptoms:
1. Problems regulating appetite
2. Problems regulating sleep
3. Low energy
4. Low self-esteem
5. Difficulty concentrating and making decisions
6. Feelings of hopelessness
Understanding Mood Disorders:
Behavioral and Cognitive changes come with Depression:
Negative thinking
Behavioral aspects could include anxiety and substance abuse (self-medicating)
Depression is widespread
Women risk of major depression is nearly double to men 13% men/22% Women
Most major depressive episodes self-terminate
Therapy helps, but most people eventually recover on their own.
Stressful events related to work, marriage, and close relationships often precede depression.
Stressful incidents correlate with depression
Death/marital crisis, physical assault- related to depression
More younger people are experiencing depression
Perhaps more reporting of depressive feelings.
Biological Perspective
Genetic Influences:
Mood disorders runs in families, risks increase with a family member who manifests behavior
Twin studies really show this
Close-up-
Suicide
1 million people worldwide take their own life
Racial differences- whites 2xs more often as blacks
Gender differences- women more likely to attempt, men more likely to complete the job.
Age differences-late adulthood increases/ peaks at middle age
Group differences- higher rate among rich/non religious/single/widowed/divorce/gay and lesbian youth
Wednesdays are bad.
Correlation with depression, when people are coming out of a depressive episode
Correlation with alcohol disorder
Suicide can be reduced by- jump barriers/unavailability of loaded guns
Social Suggestion may trigger suicide-publicity
Associated with the need to connect and belong/the failure to achieve a big goal..
Suicidal people give hints- giving possessions away, verbal hints, preoccupation with death
Sometimes a suicide attempt is a plea for help.
· “So, if a friend talks suicide to you, it’s important to listen and to direct the person to professional help. Anyone who threatens suicide is at least sending a signal of feeling desperate or despondent.”
Self-Injury: Non-suicidal self-injury (NSSI)
Adolescents
Cutting/burning/hitting/pulling hair
More females than males
Thoughts- extremely self-critical, poor communication/poor problem solving
Relieves negative thoughts through distraction
Gain attention
Relieve guilt by self-punishment
The Depressed Brain:
Neurotransmitters
Norepinephrine- increases arousal/boosts mood/ scarce during depression (smoking increases)
Serotonin- creates euphoria, diminished serotonin associated with depression (SSRI selective Serotonin Reuptake Inhibitor)
Diminished brain activity in depressive mood left frontal
Brain size depressed people smaller frontal lobes
Hippocampus with stress related damage
Pet scans
Exercise increases serotonin
Alcohol increases depression
Social Cognitive Perspective
The role of thinking and acting in depression
Low self esteem
Negative thought patterns/their future
Catastrophizing
Minimizing the positive
Negative Thoughts and Negative Moods
Learned helplessness, more common in women, stress association,
Over thinking, ruminating,
Negative Explanatory Style
Martin Seligman-
depression researcher, said, “individualism and the decline of commitment to religion and family have forced young people to take personal responsibility for failure or rejection.”
Depression’s Vicious Cycle
The vicious cycle of depressed thinking Cognitive therapists attempt to break this cycle, as we will see in Module 71, by changing the way depressed people process events. Psychiatrists attempt to alter with medication the biological roots of persistently depressed moods
Module 68 Schizophrenia
- Describe the patterns of thinking, perceiving, and feeling that characterize schizophrenia.
- Contrast chronic and acute schizophrenia.
- Discuss how brain abnormalities and viral infections help explain schizophrenia.
- Discuss the evidence for genetic influences on schizophrenia, and describe some factors that may be early warning signs of schizophrenia in children.
Introduction:
Maxine- a schizophrenic, delusions…
Nearly 1 in 100 people, 60% men develop schizophrenia
24 million across the world
Symptoms of Schizophrenia
Definition of Schizophrenia:
Means “split mind”/relates to “split from reality” characterized by disturbed perceptions, disorganized thinking and speech, diminished/inappropriate emotions. “Psychosis- irrationality and lost contact with reality”
Disorganized Thinking and Disturbed Perceptions:
· Thinking is Fragmented and bizarre, distorted by false beliefs/delusions (false thoughts)
· Some paranoid tendencies/delusions of persecution
· Word Salad- jumbled words/sentences
· Hallucinations are common/sensory experiences without sensory stimulation
· See/feel/taste/smell/voices/barking out insults/cursing
· The unreal seems real
· (issue of malfunction of “Selective Attention”/distraction
Diminished and Inappropriate Emotions
(Book Living With Schizophrenia)
Expressed emotions are usually inappropriate
Sometimes they react with flat affect
Motor behavior may be inappropriate.
Compulsive acts/rocking/rubbing an arm
Catatonia- remaining motionless for hours
Many people with schizophrenia have extreme difficulty
With medication, they can function, but many cannot.
Onset and Development of Schizophrenia
Typically strikes young people/adolescent onset
More men and more severely
Chronic Schizophrenia or Process Schizophrenia
Sometimes it’s gradual onset,
Recovery is doubtful
Exhibits negative symptoms/social withdrawal
Men who develop schizophrenia early
Acute or Reactive Schizophrenia
Sometimes it’s sudden onset
Due to life stresses
Recovery is more likely
Reflect positive symptoms
Respond well to medication
Positive Symptoms-
· Presence of inappropriate behavior
· hallucinations/talk in disorganized ways/inappropriate laughter
Negative Symptoms-
· Absence of appropriate behaviors
· toneless voices/expressionless faces/mute/rigid bodies
Understanding Schizophrenia:
Brain Abnormalities
Brain manifestation of Schizophrenia
Brain abnormalities
Low activity in frontal lobe
Problem with integrated function/connectivity
Hallucinations show activity in thalamus
Paranoia shows activity in the amygdala (emotion and fear)
Brain Structures:
Enlarged fluid-filled areas
Shrinkage and thinning of cerebral tissue
Shrinkage of thalamus
Shrinkage of Cortex
Shrinkage of corpus collosum
Genetic predispositions
Biochemical Connections
· Dopamine Overactivity
· Excessive receptors for dopamine found in brains of schizophrenics (6 times as many)
· Causes hallucinations and paranoia (too much dopamine)
Causes of Schizophrenia:
Correlation/fetal-virus infections play a contributing role
Genetic Factors
Twin Studies show strong correlation
Family studies show strong correlation too
Psychological Factors
Module 69 Other Disorders
· Somatic
· Dissociative
· Eating
· Personality
Somatic Symptoms and Related Disorders
Medically unexplained illnesses
No physical cause of illness identified
Could be unconscious psychological origin
Somatic Symptom Disorder
“symptoms are psychological in origin.”
Conversion Disorder
· AKA “Functional Neurological Disorder”
· Anxiety is converted into a physical symptom
· Freud tried to explain this
· Unexplained paralysis
· Unexplained blindness
· “inability to swallow”
Illness Anxiety Disorder
· (AKA Hypochondriasis)
· Relatively common
· People interpret trivial normal sensations as symptoms of a terrible disease
· Sympathy
· Temporary relief from daily pressure
· Reinforce complaints
· Patients commonly sees multiple doctors.
Dissociative Disorders:
· Rare
· Disorder of consciousness
· Sudden loss of memory
· Or change in identity
· Often in response to overwhelming stressful situation
Dissociative Identity Disorder
Fugue State
· A person’s conscious awareness is said to dissociate (become separated)
· From painful memories, thoughts, feelings
· Amnesia
· Short lived
· Unplanned travel is common for Fugue reports
· Sometimes new identity
· Memory comes back
Dissociative Identity Disorder p 695
· D.I.D. (formerly multiple personality disorder)
· Dissociation of the self from ordinary consciousness
· “In which two or more distinct identities are said to alternately control the person’s behavior.”
· Each personality has its own voice + mannerisms
· The original personality usually denies the awareness of the others
Understanding D.I.D.
· Some evidence it is a cultural phenomenon
· No Japan
· No India
· Are people acting out fantasies?
Some researchers see it as a real disorder
· Evidence- brain and body states
· Handedness sometimes switches with personality
· Shifted visual acuity
· Shifting activity in brain areas control of inhibitions
D.I.D. and Psychodynamic approach
Say DID is way of dealing with anxiety
Unacceptable impulses push a new personality able to act on forbidden impulses
