Study Notes
Etiology of Mood Disorders
Neurobiological Factors
- Genetic influences indicated by twin and adoption studies, with bipolar disorder showing the highest heritability.
- Polymorphism of the serotonin transporter gene linked to vulnerability to depression under stress.
- Gene DRD4.2 associated with major depressive disorder (MDD), indicating mood disorders are likely polygenic.
- Neurotransmitter levels impact mood:
- Norepinephrine: Low linked to depression; high linked to mania.
- Dopamine: Low linked to depression; high linked to mania. Depression may involve decreased responsiveness to dopamine-enhancing drugs.
- Serotonin: Low levels contribute to both depression and mania; receptor insensitivity may exacerbate symptoms.
Brain Imaging Studies
- MDD shows alterations in brain areas regulating emotion:
- Amygdala: Hyperactivity observed in MDD and bipolar I individuals, indicating a heightened emotional response.
- Subgenual anterior cingulate: Elevated activity associated with depression.
- Anterior cingulate cortex: Increased activity during emotional regulation tasks in bipolar I.
- Hippocampus and dorsolateral prefrontal cortex: Diminished size/function in both depression and bipolar disorders, affecting emotion regulation.
- Striatum: Overactivity linked to manic episodes.
Neuroendocrine System
- Hyperactivity of the HPA axis noted in MDD; poor cortisol suppression can damage body systems, particularly the hippocampus.
- Higher cortisol levels in individuals with depression, with conditions like Cushing syndrome causing depressive symptoms due to cortisol overproduction.
Social Factors
- Life stressors play a crucial role in initiating mood disorders; their impact declines in subsequent episodes.
- Low social support and high levels of expressed emotion (EE) increase the risk of relapse in depression.
- Depressive symptoms can provoke negative responses from others, compounding interpersonal challenges and leading to a negative self-concept that undermines received support.
Psychological Factors
- Neuroticism is a strong predictor of depression onset and is associated with anxiety and persistent depressive disorder (PDD).
- Cognitive theories emphasize negative thought patterns as a major cause of depression:
- Beck’s theory identifies a negative triad impacting self-perception.
- Hopelessness theory posits that perceptions of stability and globality of negative events increase hopelessness, a precursor to depression.
- Rumination theory suggests repetitive dwelling on negative experiences escalates depressive risk, particularly among women.
Social and Psychological Factors in Bipolar Disorder
- Individuals with bipolar disorder often experience both manic and depressive episodes.
- Factors triggering depression in bipolar disorder mirror those for major depressive episodes.
- Predictors of mania include:
- Reward sensitivity indicating disturbances in the reward system; goal attainment can trigger manic episodes.
- Sleep disruptions increasing susceptibility to manic episodes, with sleep protection advised as a management strategy.
Treatment of Mood Disorders
- Antidepressants target neurotransmitters: serotonin, norepinephrine, and dopamine.
Psychological Treatments for Depression
- Interpersonal Psychotherapy (IPT): Focuses on resolving interpersonal issues and enhancing communication; effective for various populations.
- Cognitive Therapy: Addresses maladaptive thoughts, promotes positive thinking, and encourages engagement in rewarding activities. Includes mindfulness-based cognitive therapy for relapse prevention.
- Behavioral Activation Therapy: Increases participation in rewarding activities, disrupting depressive cycles.
- Behavioral Couple’s Therapy: Enhances communication and relationship satisfaction, particularly for depressed individuals with relationship stress.
Psychological Treatments for Bipolar Disorder
- Medication is essential, but psychological strategies support treatment.
- Interpersonal and Social Rhythm Therapy (IPSRT): Regulates circadian rhythms and establishes stable routines.
- Psychoeducational approaches improve understanding of symptoms and encourage treatment adherence.
- Cognitive therapy incorporates early signs of manic episodes; family-focused therapy enhances communication and coping strategies.
Intensive Support Programs
- Increased nursing care and structured follow-up improve outcomes for individuals with bipolar disorder. Various programs have shown effectiveness in providing additional resources and support.### ANXIETY DISORDERS: ETIOLOGY
- Anxiety disorders are influenced by fear conditioning through Mowrer’s two-factor model: classical conditioning creates fear responses, while operant conditioning maintains avoidance behaviors.
-
Genetic factors:
- Twin studies show 20-40% heritability for specific phobias, social anxiety disorder (SAD), Generalized Anxiety Disorder (GAD), and PTSD; 50% for panic disorder.
-
Neurobiological factors include:
- Increased activity in the fear circuit, especially in the amygdala.
- Reduced activity in the medial prefrontal cortex.
- Dysfunctions in serotonin, norepinephrine, and GABA systems.
-
Personality traits:
- Behavioral inhibition in infancy can predict later anxiety disorders, particularly social anxiety.
- Neuroticism predicts both anxiety and depression onset.
-
Cognitive factors:
- Negative beliefs maintain anxiety; safety behaviors exacerbate issues.
- Perceived lack of control stems from childhood trauma or restrictive parenting, increasing vulnerability to anxiety disorders.
- Heightened attention to threat cues intensifies anxiety.
SPECIFIC ANXIETY DISORDERS
-
Specific Phobia:
- Conditioned through direct experiences or learned behaviors.
- Evolutionary predispositions create persistence for fears of inherently dangerous stimuli (prepared learning).
-
Social Anxiety Disorder:
- Developed through negative social experiences; avoidance is maintained as it reduces fear.
- Excessive focus on negative self-evaluations intensifies fear of social situations.
-
Panic Disorder:
- Characterized by misfiring of the fear circuit and high norepinephrine levels.
- Panic attacks can become conditioned responses to internal bodily sensations.
-
Agoraphobia:
- Driven by fear of having anxiety in public spaces and negative beliefs about anxiety's consequences.
-
Generalized Anxiety Disorder:
- Comorbid with other anxiety disorders and depression; individuals worry to avoid unpleasant emotions.
TREATMENT OF ANXIETY DISORDERS
- Low treatment-seeking rates: Many individuals with anxiety disorders do not pursue therapy.
-
Common features across therapies:
- Exposure therapy is critical to confront fears and alleviate anxiety without reliance on safety behaviors.
-
Phobias:
- In vivo exposure is preferred over systematic desensitization.
-
Social Anxiety Disorder:
- Involves role-playing and social skills training to reduce avoidance behaviors.
-
Panic Disorder:
- Panic control therapy uses exposure techniques to counteract panic triggers.
- Cognitive therapy is effective in restructuring thoughts related to bodily sensations and panic.
-
Generalized Anxiety Disorder:
- Relaxation training and cognitive therapy focused on tolerating uncertainty are crucial for managing symptoms.
OCD AND RELATED DISORDERS: ETIOLOGY
- Geared by genetic and neurobiological factors: Family histories indicate strong links with OCD.
- Cognitive and behavioral models imply compulsions are reinforced by reducing anxiety.
- Body Dysmorphic Disorder (BDD): Focus on specific features linked to attractiveness can lead to distorted self-perception.
- Hoarding Disorder: Cognitive Behavioral models emphasize organizational difficulties and attachment to possessions.
TREATMENT OF OCD AND RELATED DISORDERS
- Serotonin reuptake inhibitors are effective across OCD, BDD, and hoarding disorder.
- Exposure and Response Prevention (ERP) is the gold standard for OCD, involving gradual exposure to anxiety triggers while preventing compulsive responses.
- Cognitive approaches challenge beliefs surrounding compulsions and intrusive thoughts.
- Hoarding Treatment addresses emotional attachments to possessions and involves gradual exposure to decluttering.
TRAUMA-RELATED DISORDERS: ETIOLOGY
- PTSD correlates with genetic predispositions, selective attention to threats, and neuroticism.
- Degree and type of trauma heavily influence the likelihood of developing PTSD; human-caused traumas are more severe than natural disasters.
- Neurobiological connections: Reduced hippocampal volume is consistently observed in PTSD patients.
TREATMENT OF TRAUMA-RELATED DISORDERS
- SSRI medications are standard but have risks of relapse upon discontinuation.
- Exposure therapy is more effective than traditional psychotherapy for PTSD by allowing individuals to confront trauma memories.
- Cognitive strategies help process trauma and combat self-blame.
DISSOCIATIVE DISORDERS: ETIOLOGY
- Traumatic events often lead to repression of memories, resulting in dissociative symptoms.
- Dissociative Identity Disorder (DID) theories focus on trauma coping mechanisms and role-playing behavior shaped by therapeutic influences.
- Nearly all patients report severe childhood abuse as a critical factor in DID development.
TREATMENT OF DISSOCIATIVE DISORDERS
- Treatment aims for integration of identities and addressing traumatic memories.
- Psychodynamic therapy, hypnosis, and cognitive-behavioral strategies are useful in treating DID.
SOMATIC SYMPTOM-RELATED DISORDERS: ETIOLOGY
- Individuals commonly display excessive health anxiety with minimal concordance among twins.
- Neurobiological responses involve increased activity in regions associated with distress from somatic sensations.
TREATMENT OF SOMATIC SYMPTOM-RELATED DISORDERS
- Building trust between healthcare professionals and patients reduces anxiety surrounding health concerns.
- Cognitive-behavioral therapy (CBT) effectively addresses emotional triggers and alters perceptions regarding somatic symptoms.
SCHIZOPHRENIA: ETIOLOGY
- Genetic risk is heterogeneous; twin studies indicate a higher risk among monozygotic twins for developing schizophrenia.
- Dopamine theories suggest a key role in the manifestation of symptoms, with medications targeting dopamine receptors.
- Neuroanatomical changes such as enlarged ventricles and reduced gray matter in key brain regions correlate with disorder severity.
TREATMENT OF SCHIZOPHRENIA
- Treatment typically involves a combination of antipsychotics, psychosocial therapies, and family education.
- Cognitive-behavioral therapy (CBT) helps manage maladaptive beliefs and negative symptoms.
- Social skills training and family therapies provide support and long-term management of the disorder.### Case Management and Treatment for Schizophrenia
- Case managers coordinate medical and psychological services for individuals with schizophrenia, helping them live independently outside institutions.
- Residential treatment homes, also known as "halfway houses," support those not needing hospital care but requiring assistance for daily living.
- Vocational rehabilitation programs in residential settings teach marketable skills, promoting employment and community integration.
- Supportive employment provides job coaching and training to maintain employment.
Substance Use Disorders (SUD)
Etiology and Risk Factors
- Physiological dependence on substances develops over time and is influenced by various factors.
- The frontal cortex develops during adolescence, making decision-making and impulse control vulnerable during substance experimentation.
- Genetic predisposition plays a significant role; relatives of problem drinkers exhibit higher rates of alcohol abuse.
- Monozygotic (MZ) twins show greater concordance for various substance use disorders compared to dizygotic (DZ) twins.
- Environmental influences, like peer and parental behaviors, significantly impact adolescent substance use.
Neurobiological Factors
- Most substances, including alcohol, activate dopamine systems associated with pleasure.
- Deficiency in dopamine receptors, particularly DRD2, contributes to substance dependence.
- People may use drugs to alleviate withdrawal symptoms, leading to relapse.
- Incentive-sensitization theory explains heightened craving for drugs due to increased sensitivity to drug-associated cues.
Psychological Factors
- Drug use reinforces positive emotions and diminishes negative ones.
- Expectancies about drug effects influence usage; high expectations lead to increased consumption.
- Specific personality traits, like high negative emotionality and low constraint, heighten the risk for SUDs.
Sociocultural Factors
- Alcohol is the most widely used substance, with marijuana as the second; social availability influences usage rates.
- Family dynamics, such as parental alcohol use, affect the likelihood of developing drinking problems.
- Social influence and selection models indicate that drinking behaviors within peer groups influence individual consumption.
Treatment Approaches for SUD
- Acknowledgment of the addiction problem is crucial for effective treatment.
- Detoxification is often the first step, particularly in inpatient settings, followed by ongoing support like Alcoholics Anonymous (AA).
- Cognitive-behavioral therapies (CBT) focus on reinforcing positive behaviors and preventing relapse.
- Moderation in drinking can be achieved through guided self-change and controlled drinking strategies.
Smoking Cessation
- Peer influence is significant in quitting; those whose peers quit are more likely to follow suit.
- Strategies to quit smoking include gradual nicotine reduction and psychoeducational programs.
- Nicotine replacement therapies, such as patches and gum, assist in managing withdrawal symptoms.
Treatment for Drug Use Disorders
- Detoxification marks the initial stage of treatment; interventions like CBT are effective in combating cocaine use.
