Unit 6 Notes Your notes are yellow

2 Defining Disorders Psychological disorder- a harmful dysfunction in which thoughts, feelings, or behaviors are maladaptive, unjustifiable, disturbing, and atypical In order for something to be considered a disorder, it MUST have all four characteristics Lets look at each one and compare to our scenarios…

3 Defining Disorders Maladaptive- destructive to oneself or others
Nude bather? Might be weird, but its not hurtful to himself or others (NO) Woman afraid of snakes? Keeps her from living a normal life (YES) Teenage boy? Temperatures are dangerous to be exposed to (YES) Teenage girl? Not eating or sleeping is not good for her health (YES)

4 Defining Disorders Unjustifiable- without a rational basis
Background info may be necessary in order to determine Nude bather? Is actually Ben Franklin and the practice of air bathing was a common practice during his time (NO) Woman afraid of snakes? There are no poisonous snakes in her area (YES) Teenage boy? He is a member of the Santee Sioux and a vision quest is part of his spirituality (NO) Teenage girl? Entire family died in a house fire three days ago (NO)

5 Defining Disorders Disturbing- troublesome to others Nude bather?
No one saw him, so no one was disturbed (NO) Woman afraid of snakes? Husband was very concerned about her (YES) Teenage boy? Right of passage most likely pleased his family (NO) Teenage girl? Those close to her were probably quite concerned (YES)

6 Defining Disorders Atypical- so different that is violates the norm
Behavior is NOT like other people’s behavior AND violates a rule for accepted and expected behavior in a particular culture Nude bather? Today? Yes. During the 1700s? No Woman afraid of snakes? Most people aren’t afraid of pretend snakes is not acting normally (YES) Teenage boy? Santee culture would consider his behavior normal (NO) Teenage girl? Most people would act in a similar manner in a similar situation (NO)

7 Understanding Disorders
Cultures have tried to explain psychological disorders for hundreds of years Ancient Babylonians viewed disorders as demonic possession and treated them with prayer Ancient Hebrews saw disorders as punishment for sin and also used prayer to heal 15th Century Europeans tortured and executed those with disorders as it was believed they were caused by Satanic possession Today, disorders are most commonly explained through either the medical or bio-psycho-social model

8 Understanding Disorders
Medical Model- concept that mental diseases have physical causes that can be diagnosed, treated, and in most cases, cured Developed from the practices of French physician Philippe Pinel, who saw psychological disorders as sickness, not demonic possession While the medical model has proven to lead to treatment of some disorders, it ignores all other factors that may play a role in needed treatment

9 Understanding Disorders
Bio-psycho-social Model- assumes biological, psychological, and social factors combine and interact to produce psychological disorders Biological includes our genetic disposition for a disorder Psychological includes our thoughts and thinking patterns Social includes cultural beliefs that can affect our behaviors

10 Classifying Disorders
Clinical psychologists and psychiatrists classify psychological disorders according to their symptoms to do the following: Describe the disorder Predict the future course of the disorder Treat the disorder properly Provide a springboard for research into the disorder’s causes DSM-V: The American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders, is a widely used system for classifying psychological disorders

11 Classifying Disorders
Notes about the DSM-V Replaced the DSM-IV-TR in May of 2013 Has gone through significant changes Anorexia wasn’t in the 1st edition; homosexuality was dropped in the DSM-III Is widely accepted, but not universally accepted

13 Anxiety Disorders Anxiety- vague feeling of apprehension and nervousness Feeling nervous is perfectly normal behavior- it only becomes a disorder when it take control and dominates your life!

14 Anxiety Disorders There are five kinds of anxiety disorders:
Generalized Anxiety Disorder Panic Disorder Phobia Obsessive-Compulsive Disorder (OCD) Post-Traumatic Stress Disorder (PTSD)

15 Anxiety Disorders Generalized Anxiety Disorder- characterized by disruptive levels of persistent unexplained feelings of apprehension and tenseness Must display at least three of the following symptoms: Restlessness Feeling on edge Difficulty concentrating or mind going blank Irritability Muscle tension Sleep disturbance Symptoms are longer lasting and are not tied to any specific event to those with this disorder

16 Anxiety Disorders Panic Disorders- characterized by sudden bouts of intense, unexplained anxiety, often associated with physical symptoms like choking sensations or shortness of breath Attacks happen several times a day and all your energy is directed at regaining control

17 Anxiety Disorders Phobia- characterized by disruptive, irrational fears of objects, activities, or situations True phobias are irrational and disruptive Focus anxiety onto a feared object, activity, or situation

18 Anxiety Disorders Obsessive-Compulsive Disorder (OCD)- characterized by unwanted, repetitive thoughts and actions Most common obsessions: Concern with dirt, germs, or toxins Something terrible happening Symmetry, order, or exactness Most common compulsions: Excessive hand washing, bathing, tooth brushing, or grooming Repeating rituals Checking doors, locks, appliances, homework, etc.

19 Anxiety Disorders Post-Traumatic Stress Disorder (PTSD)- characterized by reliving a severely upsetting event in unwanted, recurring memories and dreams Usually triggered by intense stress Symptoms can include nightmares, persistent fear, difficulty relating to others, and troubling memories of or flashbacks to the traumatic event One study showed that ¼ of all US vets from Iraq and Afghanistan were diagnosed with PTSD

20 Anxiety Disorders Biological causes:
Heredity- some people have a predisposition for developing an anxiety disorder Brain function Those with OCD have more activity in their frontal lobes than those without Those with phobias have unusual activity in their amygdala Evolution We have learned what is dangerous and should be feared over generations

21 Anxiety Disorders Learning Factors: Conditioning
If we are bit by a dog as a child, we can develop a fear of dogs that lasts into adulthood Observational Learning: If our parents or siblings are afraid of something, we can develop the same fear Reinforcement Someone with OCD and feels the need to wash their hands feels better when they wash they’re hands- the behavior has been reinforced

22 Mood Disorders Disturbances of emotions- magnifications of our normal reactions Magnified states are mania and depression Mania- period of abnormally high emotion and activity Depression- feeling down, sad or drained of energy Two major disorders: Major Depressive Disorder and Bipolar Disorder

23 Mood Disorders Major Depressive Disorder- a person, for no apparent reason, experiences at least two weeks of depressed mood, diminished interest in activities, and other symptoms such as feelings of worthlessness Diagnosed when 5 of these 9 symptoms are present for for two or more weeks: Depressed mood most of the day, nearly every day** Little interest or pleasure in almost all activities** Significant changes in weight or appetite Sleeping more or less than usual Agitated or decreased level of activity Fatigue or loss of energy Feelings of worthlessness or inappropriate guilt Diminished ability to thing or concentrate Recurrent thoughts of death or suicide

24 Mood Disorders Bipolar Disorder- person alternates between the hopelessness of depression and the overexcited and unreasonably optimistic state of mania During mania phases, the person may go long periods without sleeping and may experience racing thoughts, be easily distracted, and set impossible goals

25 Mood Disorders Biological Factors: Heredity- Brain function-
Many mood disorders run in families (if one twin has bipolar disorder, the other is 70% more likely to develop it) Brain function- PET scans show less active brain functioning during major depression Certain neurotransmitters (serotonin and norepinephrine) are lacking during depression

26 Mood Disorders Social-Cognitive Factors: Learned helplessness-
When bad things happen, some people tend to give up trying to improve their situation May be why women suffer higher rates of depression than men Attributions- When things go wrong, we try to explain them Depressed people tend to explain things as stable, internal, and global

27 Dissociative Disorders
The sense of self has become separated (dissociated) from previous memories, thoughts, or feelings Quite rare and usually represent a response to overwhelming stress Three specific types: Dissociative Amnesia Dissociative Fugue Dissociative Identity Disorder

28 Dissociative Disorders
Dissociative Amnesia- Characterized by the loss of memory in reaction to traumatic event Unlike other memory loss, it MUST be tied to a traumatic event Example: combat solider not remembering events before or after his platoon is hit by a roadside bomb

29 Dissociative Disorders
Dissociative Fugue- characterized by loss of identity and travel to a new location Can last anywhere from a few hours to even years In extreme cases, the person can form new friendships, completely new identities, and even work in a completely different career field

30 Dissociative Disorders
Dissociative Identity Disorder- rare and controversial disorder in which an individual exhibits two or more distinct and alternating personalities Formally known as multiple personality disorder Personalities can differ in age, race, gender, even handedness Controversial because was once extremely rare (less than 100 cases before the 1970s to over 20,000 during the 1980s) and because number of personalities has increased, on average, from 3 to 12

31 Somatoform Disorders Symptoms take a bodily form without apparent physical cause Hypochondriasis- imagined symptoms of illness Example- athlete physically has severe knee pain after an awkward fall, but doctors cannot find any medical reason for the pain Pretending to be sick is NOT hypochondriasis

32 Personality Disorders
Lasting and rigid behavior patterns that disrupt social functioning Antisocial personality disorder- person (usually male) shows a lack of conscience for wrongdoing and a lack of respect for the rights of others Also known as psychopathic personality disorder Common amongst severe criminals

33 Schizophrenic Disorders
Schizophrenia- series of disorders characterized by disorganized and delusional thinking, disturbed perceptions, and inappropriate emotions and behaviors NOT split personalities- the person is split from reality Occurs in about 1% of the world’s population

34 Schizophrenic Disorders
Symptoms: Delusions- false beliefs Grandeur- false beliefs that you are more important that you really are (believing you are Jesus or Buddha, for example) Persecution- false beliefs that people are out to get you (believing that the CIA is listening to all of you phone calls, for example) Sin or Guilt- false beliefs of being responsible for some misfortune (earthquake happens because you didn’t do your chores) Influence- false beliefs of being controlled boy outside forces (“the devil made me do it”)

35 Schizophrenic Disorders
Symptoms (continued): Hallucination- false perception Hearing voices, seeing non-existent objects, feeling a burning sensation that isn’t there Inappropriate emotions or behaviors Laughing during a sad moment

36 Schizophrenic Disorders
Causes: Biological: Genetics- chances increase if a relative has it Brain structure- smaller amounts of brain tissue and larger, fluid- filled spaces around the tissue. Thalamus can also be smaller Brain function- PET scans show that the frontal lobes have less activity than normal brains. Also, more receptor sites for dopamine Prenatal viruses- if the mother has the flu, it MAY increase risk

37 Therapy There are many ways to treat psychological disorders- some are more widely accepted than others It is important to note that there is NO ONE SINGLE correct treatment for any disorder

38 Psychotherapy An interaction between a trained therapist and someone who is seeking to overcome psychological difficulties or achieve personal growth Depending on the patient, the type of therapy may vary Examples: Psychoanalysis Client-centered therapy Behavior therapy Cognitive therapy Family and Group Therapy

39 Biomedical Therapy Treatment of psychological disorders by changing the brain’s functioning with prescribed drugs, electroconvulsive therapy, or surgery

40 Drug Therapy Introduction of drugs allowed for record numbers of patients to become deinstitutionalized (released from mental hospitals and back into the community) Drugs fall into three categories: Antipsychotic Antianxiety Antidepressant

41 Drug Therapy Antipsychotic drugs-
Primarily used to treat schizophrenia Reduce the number and severity of delusions and hallucinations by blocking the activity of dopamine Thorazine is the most common Negative side effects are strong enough that some people discontinue use

42 Drug Therapy Antianxiety Drugs-
Treat people with high levels of stress or anxiety disorders Boost GABA in the brain Valium, Librium, and Xanax are common Patients can become dependent on the drugs- need to be used with other forms of therapy

43 Drug Therapy Antidepressants –
Boost serotonin levels in the brain to treat major depression Prozac, Zoloft, and Paxil (Lithium for Bipolar) In 2008, 1:20 men, 1:10 women had a prescription

44 ECT Electroconvulsive Therapy (ECT)
Therapy for major depression in which a brief electric current is sent through the brain of a patient Can be more effective than drug therapy Can cause minor memory loss There is no clear cut reason why the procedure works

45 Psychosurgery Lobotomy- once used to control emotionally unstable or violent patients by cutting the nerves that connect the front lobes to the deeper emotional centers of the brain Surgery is only used as a last resort in treating psychological disorders
