DSM: While you are not expected to memorize diagnostic criteria you should know the key features of each disorder and you should be able to differentiate the disorders (you might find the use of flash cards especially helpful here). Mood Disorders: characterized by mood episodes that are discrete periods of time in which a number of specific mood related symptoms are present and they represent a change from previous functioning. Key Concepts: o Mania o Depression o Mixed Episode Major Depressive Disorder and Dysthymic Disorder o Key differences between MDD and Persistent Depressive Disorder (Dysthymic Disorder) o MDD: Key criteria for diagnosis o Double Depression o Specifiers i.e., Severity and Subtypes for MDD o Depression, the life cycle and prognosis o Causal factors: • Biological • Personality Traits, Interpersonal, Environmental: Social supports, childhood adversity (Cinderella) • Cognitive and behavioral – general factors and Beck’s Cognitive Triad and Learned Helplessness (The Tornado Study) Bipolar Disorders: Characterized by the presence of one or more manic, mixed (mania and depression) or hypomanic episodes. o Bipolar I: one or more manic or mixed episode that swings to normal or depressive symptoms (emphasis on Manic) o Bipolar II: one or more depressive episodes combined with swings to hypomania (emphasis on depression) o Bipolar I and II usually cycle 2 or 3 times a year; “rapid cycler” has mood swings 4 or more times a year. o Cyclothmic disorder: Two or more years with hypomania or hypomania with depressive swings o Causal Factors: biological, psychological Treatments for Mood Disorders o Medications o Antidepressants (know specific classes o Mood Stablizers (know specific examples – Lithium, etc) o ECT and Sunlamps o Psychotherapy – treatment(s) of choice Test your knowledge: True or False • If Cinderella had been real she would have been at risk for the development of major depressive disorder. • Adopting a pessimistic way of living can contribute to the development of mood disorders. • A depressed individual who experiences delusions would be diagnosed with major depressive disorder with atypical features. • The relationship between severe stress and depression is strongest for first time episodes. • According to your text, Beck’s negative cognitive triad includes thoughts about self, significant others and relationships. • If a person has had a manic episode, the diagnosis must be bipolar I. • Depressive episodes in Unipolar Major Depression are the same as those found in Bipolar Disorders. Somatic Symptom Disorders: Presence of physical symptoms for which no organic cause can be determined Illness anxiety disorder: Believes has or will develop a serious medical illness despite contrary evidence. • Comorbidity, Age of Onset • Differentiate from Somatic Symptom Disorder Somatic symptom disorder: Presence of somatic symptoms with no physical cause can be determined • Demographics, Comorbidity, Course • Diagnostic criteria Functional Neurological Symptom Disorder AKA Conversion disorder: loss of bodily function, sudden onset, situations of duress (stress) • History and etiology from a Freud’s perspective, primary and secondary gains • Behavioral perspective: etiology and sustaining variables • Prevalence, Demographics, Culture Factitious Disorder And Factitious Disorder by Proxy o Key Characteristics Test your knowledge: • Factitious disorder by proxy is when a person inflicts medical or physical illness in themselves.

How do Freud’s beliefs differ from cognitivists and behaviorists? • What is the relationship between culture and somatic symptoms disorders such as functional neurological symptom disorder? Dissociative Disorders: Characterized by change(s) in the normal, integrated functions of a person’s identity, memory, or consciousness • Casual factors: environmental, biological Depersonalization/Derealization Disorder: Subjective sense of being outside of one’s own body and/or environment. Feels like you lose control of actions; however, reality testing stays in tact • Depersonalization vs. Realization – definitions and respective subjective experiences • Risk and Casual Factors: environmental, biological Dissociative Amnesia/Dissociative Amnesia with Fugue: Sudden loss of memory for important personal information; non-organic • Localized amnesia, Selective amnesia • Characteristics of fugue • Dateline NBC story on Dissociative Fugue (featuring David Earle) Dissociative Identity Disorder (DID), formerly called Multiple Personality Disorder: Person possesses two or more distinct personalities. Personalities take turns controlling one’s actions, results in gaps regarding important personal information (activities) • Prevalence over time • Causes • Intervention, Risks (hypnosis, memory) Test your knowledge: • How did Freud dissociative phenomena i.e., etiology and intervention? Are Freud’s views still accepted today? • Compare and contrast depersonalization vs. derealization. • Malingering is a type of somatoform disorder. True or False? • What is the role of stress as a causative factor for various dissociative disorders? • What are the challenges associated with diagnosing DID? Schizophrenia: Thought disorder characterized by the presence of severe hallucinations and delusions Key Terms: • Hallucinations (including common types) • Delusions • Symptom patterns: positive symptoms, negative symptoms, specific subtypes Etiology: • Diathesis stress • Dopamine Hypothesis • Glutamate • Enlarged ventricles • Hypofrontality • Prevalence Phases: Prodromal, Active, Residual Subtypes (Key Characteristics) • Catatonic • Disorganized • Paranoid • Undifferentiated • Residual Prognosis and Treatment • Prognosis: Rule of Thirds • Medications: Antipsychotics • Interventions (types, effectiveness, most desired approaches) Test your knowledge: • A hallucination refers to a false belief. True or False • What biological and environmental diatheses are associated with development of schizophrenia? • In reference to schizophrenia, name and define several positive symptoms. Name and define several negative symptoms. • How have we come to understand the presence of seemingly enlarged ventricles in schizophrenia? • What is the “Rule of Thirds”? • Which neurotransmitters play a key role in schizophrenia? Explain. Substance Abuse and Addiction • Key Concepts o Substance use • Impaired control • Social impairment • Risky use • Pharmacological (tolerance, withdrawal) • Most commonly abused substances • DSM IV vs DSM 5 o Substance abuse vs dependence → Substance Use Disorder and specifiers o maladaptive pattern o tolerance and withdrawal • Alcohol o Biochemical Perspectives (consumption and addiction): GABA, dopamine o Dose – risk relationships (“high” achieved, paradoxical effect, consumption rate vs absorption rate/BAL vs biological risks, mitigating factors) o Short-term and long-term risks of consumption o Lecture slide: common misconceptions regarding alcohol o Type I vs Type II alcoholism o Detox (process and risks) o Treatment • Meds • 12 step programs/self-help • Role of the environment and relapse prevention o Alcohol vs. other CNS depressants • Behavioral Addictions o Gambling Disorder o Key Characteristics o Rationale for inclusion in DSM Test your knowledge • How do DSM IV vs DSM 5 differ in conceptualizing sexual disorders, severity of dysfunction? • What is tolerance?
