Focus on Function, Not Just Symptoms

  • Shift the perspective from merely treating symptoms to fostering patient empowerment and promoting self-management for better outcomes.

  • Recognize the influence of external factors on mental health.

  • Medication management often involves trial and error, highlighting the ethical complexities involved in psychiatric treatments.

Framing

Biopsychosocial Spiritual and Cultural Model

  • Integrates multiple factors affecting mental health:

    • Biological: Genetics, Neurochemistry, Physical Health

    • Psychological: Cognition, Emotions, Behavior, Insight

    • Social: Social Support, Relationships, Socioeconomic Status

    • Spiritual: Spiritual and Cultural Beliefs, Practices, and Identity

Telling a Story and Making an Argument

  1. Predisposing Factors: Explores vulnerabilities like family history of depression or childhood trauma that may predispose an individual to mental disorders.

  2. Precipitating Factors: Identifies current stressors or triggers such as divorce or job loss contributing to episodes.

  3. Perpetuating Factors: Looks at aspects that maintain the condition, including ongoing stressors, poor sleep, or negative thought patterns.

  4. Protective Factors: What is beneficial in promoting recovery, such as supportive relationships or access to care.

Case Formulation

  • Crucial in understanding the patient’s condition beyond diagnostic criteria, addressing:

    • Why now?: Contextual factors triggering symptoms.

    • Why this way?: Unique patient experiences and manifestations.

    • What maintains it?: Factors perpetuating the condition.

    • What will help?: Identifying effective interventions.

Case Example

Details of a hypothetical patient: A 38-year-old woman shows signs of depression reflected in:

  • Low energy, mood disturbances, sleep issues, and passive suicidal ideation.

  • Family history of depression; medically controlled hypothyroidism.

  • Recent life stressors include divorce and increased isolation.

  • Reported psychiatric prior history and medical considerations suggest a multifactorial issue requiring nuanced management strategies.

Diagnostic and Statistical Manual of Mental Disorders (DSM)

  • History of the DSM: Documentation dates back to 1952, evolving to DSM-5-TR, focused on diagnosing and classifying mental disorders.

Purpose and Scope of DSM-5-TR

  • Primarily for diagnosing mental health disorders in the U.S. and Canada, and used by clinicians, researchers, and insurance companies.

Comparison with ICD-10

  • The DSM focuses exclusively on mental health and behavioral disorders, while ICD-10 encompasses a broader range of health conditions.

Mental Status Exam (MSE)

Definition and Importance

  • The MSE is akin to a physical exam in psychology, providing a snapshot of the patient’s mental state and behaviors.

  • It combines both objective observations of the clinician and subjective patient descriptions.

  • Critical for diagnosing and assessing the disorder and response to treatment, and it informs further management.

Components of the MSE

  1. Appearance: Observations on grooming and dress.

  2. Attitude: The patient’s demeanor towards the clinician.

  3. Behavior: Movement and actions noted during examination.

  4. Speech: Rate, volume, and clarity of speech.

  5. Mood: Patient-reported mood state.

  6. Affect: The observable emotional response during the exam.

  7. Thought Process: How thoughts are organized and expressed.

  8. Thought Content: What the patient is thinking about, including any delusions or hallucinations.

  9. Cognition: Assessing orientation, attention, and memory.

  10. Insight/Judgment: Understanding of one’s condition and decision-making abilities.

MSE in Primary Care – Safety First

  • Critical safety assessments include:

    • Suicidal ideation (passive vs. active, and risk assessments).

    • Homicidal ideation.

    • Presence of psychosis.

    • Behavioral issues like severe agitation.

Common Mistakes FNP Students Make

  1. Skipping proper bipolar screening.

  2. Confusing passive suicidal ideation (SI) with active.

  3. Ignoring the patient’s thought process during assessments.

  4. Overpathologizing anxiety disorders.

  5. Avoiding challenging questions related to mental health.

  6. Focusing on symptom treatment instead of a systems-based approach.

Diagnosing Mental Health Disorders

Key Elements in Diagnosis

  • Important aspects include:

    • Duration and Timing: How long symptoms persist; when they appear related to stressors, etc.

    • Etiology: Underlying medical conditions that may contribute.

    • Functioning: How the individual’s life is impaired due to the disorder.

Comparison of Features between Major Depression Disorder (MDD), Bipolar I Disorder, and Generalized Anxiety Disorder (GAD)

Feature

Major Depression Disorder (MDD)

Bipolar I Disorder

Generalized Anxiety Disorder (GAD)

Duration

≥ 2 weeks

≥ 1 week of mania

≥ 6 months of excessive worry

Timing

Episodic; can be stress-related

Distinct mood episodes; cycles

Chronic worry, not episodic

Etiology

Medical (thyroid, anemia)

Substance-induced mania

Medical (hyperthyroid, drug use)

Functioning

Impaired performance, social withdrawal

Severe impairments; risky behavior

Difficulty concentrating, irritability;

Unipolar vs. Bipolar Disorder

  • Unipolar Disorder: Characterized by depressive moods without episodes of mania.

  • Bipolar Disorder: Includes episodes of both elevated and depressed mood states, often cyclical.

  • Manic versus Hypomanic Episodes: Bipolar I requires manic episodes, while Bipolar II requires hypomanic episodes with one major depressive episode.

Key Characteristics of Bipolar Diagnostics

  • Diagnosis hinges on the presence of manic episodes in Bipolar I versus the absence in Bipolar II.

  • Risk factors include previous hospitalizations, family history of bipolar disorder, etc.

Pharmacological Treatment Approaches

Selective Serotonin Reuptake Inhibitors (SSRIs)

  • Mechanism: Block the reabsorption of serotonin, improving mood.

  • Common SSRIs include:

    • Fluoxetine (Prozac)

    • Sertraline (Zoloft)

    • Escitalopram (Lexapro)

    • Citalopram (Celexa)

    • Paroxetine (Paxil)

    • Fluvoxamine (Luvox)

Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs)

  • Mechanism: Increase both serotonin and norepinephrine levels.

  • Common SNRIs:

    • Venlafaxine (Effexor)

    • Duloxetine (Cymbalta)

    • Desvenlafaxine (Pristiq)

    • Levomilnacipran (Fetzima)

Tricyclic Antidepressants (TCAs)

  • Mechanism: Similar to SNRIs but often with more side effects.

  • Common examples include:

    • Amitriptyline

    • Doxepin (Silenor)

    • Common side effects: Dry mouth, dizziness, sedation.

Monoamine Oxidase Inhibitors (MAOIs)

  • Mechanism: Inhibit the breakdown of neurotransmitters like serotonin.

  • Risks: Potential for hypertensive crises with tyramine-rich foods.

Atypical Antidepressants

  • Various mechanisms that include increasing dopamine or selectively targeting serotonin and norepinephrine.

  • Examples:

    • Bupropion (Wellbutrin)

    • Mirtazapine (Remeron)

    • Trazodone (Desyrel)

    • Vilazodone (Viibryd)

Safety Precautions and Monitoring for Medications

  • For medications like Lithium and Valproate, monitoring includes serum levels, kidney function, liver function, and thyroid function for contraindications or potential side effects.

Sleep Disorders

Importance of Sleep

  • Sleep is foundational for mental and physical health. Poor sleep can exacerbate conditions like depression, anxiety, and increase suicidality.

Key Neurotransmitters in Sleep-Wake Regulation

  • GABA, Adenosine, Histamine, Orexin, Serotonin, Glutamate, Acetylcholine, Dopamine: These neurotransmitters play significant roles in regulating the sleep-wake cycle.

Sleep Across the Life Span

  • Average sleep duration varies across age groups from newborns requiring 14-17 hours/day to older adults needing 6-8 hours/day.

Insomnia Disorder

  • Defined as difficulty initiating or maintaining sleep, causing daytime distress or impairment, often requiring 3 nights/week for 3 months as a diagnostic criterion.

Insomnia Treatment Strategies

  • Sleep Hygiene Essentials:

    • Consistent sleep schedule, optimal sleep environment, pre-sleep routines, limitations on stimulants, and effective stress management practices.

  • Treatment Options:

    • Pharmacologic interventions: Benzodiazepines, Non-benzodiazepine hypnotics (Z-drugs), and Antihistamines.

Suicide Assessment

Understanding Suicidal Ideation

  • Differentiate between passive and active ideation:

    • Passive: Expressions of hopelessness; Active: Concrete plans to harm oneself.

Risk and Protective Factors

  • Evaluate risk factors, including prior suicide attempts and chronic pain, while considering protective factors such as family responsibilities and support networks.

Safety Planning in Primary Care

  • Important steps include removing access to means, creating coping strategies and support contacts, and providing crisis resources.

Conclusion: Managing Workload and Self-Care

Wheel Barrel Concept
