    Study Notes

    Generalized Anxiety Disorder (GAD)

    • GAD-2 screening tool has a sensitivity of 86% and a likelihood ratio (LR+) of 5.0, and an LR- of 0.17.
    • GAD-7 screening tool has a sensitivity of 97% and an LR+ of 2.2, and an LR- of 0.05.
    • GAD-7 screening tool with a score of ≥10 has a sensitivity of 89% and an LR+ of 5.1, and an LR- of 0.13.
    • Mild GAD is characterized by more than half of the time experiencing anxiety, minor functional impairment, and a GAD-7 score of 5-9.
    • Moderate GAD is characterized by most of the time experiencing anxiety, marked functional impairment, and a GAD-7 score of 10-14.
    • Severe GAD is characterized by all the time experiencing anxiety, marked functional impairment, and a GAD-7 score of 15+.

    Panic Disorder (PD)

    • Panic attack is a sudden onset of intense discomfort, anxiety, or fear that reaches a peak within minutes and is accompanied by somatic and/or cognitive symptoms.
    • Panic disorder is characterized by repeated panic attacks followed by at least 1 month of persistent concern about having another panic attack, worry about the possible implications or consequences of the attacks, or a significant behavioral change related to the attacks.
    • Agoraphobia is an anxiety disorder characterized by a fear of being in situations where escape might be difficult or that help wouldn't be available if things go wrong.
    • Prevalence of PD is 4.7% (4-8% in primary care) with a median age of onset of 24 years.
    • Risk factors for PD include genetic, female (2X), increased stress, and those who suffer from asthma.
    • Diagnosis of PD is made through interview according to DSM-5 criteria, and screening via PHQ-PD or ANS.

    Depression

    • Symptoms of depression include depressed mood, energy loss, pleasure lost, retardation or excitation, eating changed, sleep changed, suicidality, feeling of being a failure, only me to blame, and no concentration.
    • Major depressive disorder is characterized by a history of one or more major depressive episodes and no history of mania/hypomania.
    • Prevalence of major depressive disorder is 5-10% (primary care) and 2-4% (community) with a median age of onset of 30 years.
    • Risk factors for major depressive disorder include female (2-3X), genetic, history of anxiety, substance use, and adverse life events.
    • Diagnosis of major depressive disorder is made through clinical interview according to DSM-5 criteria, and screening by PHQ-9.

    Differentiating Anxiety vs. Other Conditions

    • Anxiety vs. depression: characterized by self-criticism of previous events and/or circumstances, early morning awakening, diurnal variation in mood, marked guilty preoccupations, and suicidal thoughts more commonly present in depression.
    • Anxiety vs. panic disorder: characterized by the presence of unexpected or paroxysmal panic attacks in panic disorder.
    • Anxiety vs. adjustment disorder with anxiety: characterized by the presence of an identifiable stressor or stressors occurring within three months of the onset of symptoms in adjustment disorder.
    • Anxiety vs. organic disease: distinguished via history, physical exams, and labs, including hyperthyroidism, pheochromocytoma, heart failure, arrhythmias, asthma, COPD, anemia, and others.
    • Anxiety vs. medication: patients using certain medications can present with anxiety, including alcohol, cannabis, amphetamines, analgesics, and others.

    Anxiety Disorders

    • Fear: an emotional, physical, and behavioral response to an immediately recognizable external threat (within normal or typical range)
    • Phobia: an excessive fear response to a specific object or situation that is out of proportion to the actual danger (can occur with no danger present) and cause significant dysfunction due to avoidance behavior
    • Anxiety: a distressing, unpleasant emotional state of nervousness and unease; causes are less clear and timing is less tied to a threat (anticipatory, persistent, none identifiable)

    Generalized Anxiety Disorder (GAD)

    • Excessive worry about everyday issues and situations almost daily for a duration of 6 months or greater, with multiple somatic symptoms
    • Prevalence: 8-31.2% (Primary Care)
    • Mean age of onset: 30 years
    • Risk factors: dysregulation of worry, genetics/family history, female (2X), adverse life events
    • Diagnosis: by clinical interview (according to DSM-5 criteria), screening tool: GAD-7
    • Management: patient education, referral to psychotherapy, psychiatry
    • Prognosis: 43% may develop major depression; 20-25% increased risk of suicide

    GAD - DSM-5 Diagnostic Criteria

    • Excessive anxiety and worry (apprehensive expectation), occurring more days than not for at least 6 months, about a number of events or activities
    • Difficulty controlling the worry
    • Anxiety and worry are associated with 3 (or more) of the following:
      • Restlessness or feeling keyed up or on edge
      • Being easily fatigued
      • Difficulty concentrating or mind going blank
      • Irritability
      • Muscle tension
      • Sleep disturbance (difficulty falling asleep, or restless, unsatisfying sleep)
    • Anxiety, worry, or physical symptoms cause clinically significant distress or impairment in social, occupational, or other important areas of functioning
    • The disturbance is not attributable to the physiological effects of a substance or another medical condition (e.g., hyperthyroidism)
    • The disturbance is not better explained by another mental disorder

    Mood Disorders

    • Depression (aka. Major Depressive Disorder)
    • Bipolar Disorder
    • Adjustment Disorder with Depressed Mood (e.g., grief)
    • Seasonal Affective Disorder (SAD)
    • Premenstrual Dysphoric Disorder or Postpartum/Peripartum-onset Depression
    • Substance/Medication-Induced Mood Disorder (including alcohol, cannabis, etc.)
    • Borderline Personality Disorder

    Considerations

    • Trauma- and stressor-related disorders: Stress, not elsewhere classified, Adjustment Disorder, Acute Stress Disorder
    • Organic causes of anxiety:
      • Endocrine: Hyperthyroidism, Pheochromocytoma, Hyperparathyroidism
      • Cardiopulmonary: Heart failure, Arrhythmias, Asthma or Chronic obstructive pulmonary disease (COPD)
      • Neurologic: Temporal lobe epilepsy or Transient Ischemic Attacks (TIAs)
      • Medication: corticosteroids, cocaine, amphetamines, caffeine; withdrawal

    Putting it into Practice

    • Subjective history: clinical syndrome, epidemiology, timing
    • Objective data: physical exam, MSE, screening tool, labs, and imaging
    • Pretest probability (or prevalence)
    • Natural history (prognosis if left untreated)

    Assessment

    • Assessing severity of disease as well as functional capacity
    • Impact of mental health on:
      • Living independently
      • Learning
      • Working
      • Socializing
      • Self-care
