ANXIOUS AND SAD PATIENTS

ANXIETY DISORDERS —Shirah Vollmer, MD, Associate Clinical Professor of Psychiatry and Family Medicine, David Geffen School of Medicine at the University of California, Los Angeles
Anxiety: primary care physicians see more patients with anxiety disorders than do psychiatrists; most patients anxious during even routine visit; difficult to distinguish anxiety disorder from normal anxiety during office visit; definitions— good anxiety defined as mild anxiety that mobilizes people to action; bad anxiety defined as unpleasant and overriding mental tension that leads to avoidance and impairment; ask patients what happens when they are anxious to determine whether patient has good or bad anxiety (ie, do they work harder at task or avoid task); fear different from anxiety; fear involves cognitive functions (eg, worries about terrorism), while anxiety creates tense emotional state marked by physical symptoms; symptoms of anxiety include substernal chest pain, diarrhea, constipation, and joint pain; conceptual model of anxiety as exaggerated reflexes—designed to ward off potential hazards; patients may exhibit eye blinking, gagging, coughing, trouble breathing, vomiting, and diarrhea; consider patients with irritable bowel syndrome (IBS) as having anxiety disorder until proven otherwise
Classification of anxiety disorders: spectrum includes social anxiety disorder (SAD; also called social phobia), posttraumatic stress disorder (PTSD), obsessive-compulsive disorder (OCD), generalized anxiety disorder (GAD), and panic disorder; anxiety disorder not otherwise specified (NOS) used if symptoms do not fit these categories; prevalence—SAD most common; PTSD second most common, then GAD, and panic disorder least common; anxiety and depression—2 aspects of same disorder; depression can develop in patient with untreated anxiety disorder; anxiety can develop in patient with untreated depressive disorder; treatment involves same therapeutic agents; prescribing antidepressant for anxiety disorder may confuse patients
SAD: fear of what other people think leads to impaired functioning; symptoms include stuttering, palpitations, “butterflies,” blushing, sweating, and trembling; consider using propranolol (Inderal) to treat patient with performance anxiety; referring patient to another physician for treatment may prove difficult because of patient’s social anxiety
Posttraumatic stress disorder (PTSD): reimbursable diagnosis; involves severe trauma resulting from experiencing unusual event in which person could do nothing, and as result, feels complete helplessness (helplessness key to diagnosis); patient re-experiences event through nightmares and flashbacks (dissociative-like experience); avoidance or numbing occurs in order to prevent re-experiencing traumatic event; hyperarousal to stimuli can result in inappropriate reactions and dissociation (eg, loud noises associated with gunshot fired during event)
OCD: associated with very specific symptoms that respond well to treatment with medication; obsessive component involves repetitive and intrusive thoughts (eg, “I have to wash my hands”); obsessive thoughts lead to compulsive and ritualistic behavior (eg, repetitive washing of hands); usually arises in childhood or adolescence, suggesting lifelong disorder
GAD: excessive anxiety and worry that involves various issues; associated with symptoms of restlessness and irritability; patients feel on edge or “keyed up”; treatment can improve symptoms
Panic disorder: mistaken for myocardial infarction by some patients because symptoms include substernal chest pain
Etiology: psychoanalytic theory—anxiety arises from unconscious Oedipal conflict; learning theory—anxiety is a learned behavior; children learn anxiety from anxious parents; chemical imbalance concept—some people genetically predisposed to anxiety through imbalance of neurotransmitters; involves biologic susceptibility, but early environment plays role in development; panic disorder associated with reduction in 5-hydroxytryptamine 1A (5-HT1A ) type of serotonin receptor in 3 areas of brain
Diagnostic evaluation: functional impairment—key to evaluation; assess patient for avoidance behavior involving driving, restaurants, shopping malls, and elevators; avoidance of anxiety-provoking stimuli can lead to agoraphobia; in children—anxiety expressed through crying, tantrums, or clinging behavior; most anxiety disorders begin in childhood or adolescence and result in lifelong condition; medication history—assess use of medications, caffeine, marijuana, bronchodilators, and anticholinergic agents; screening questions—useful in evaluating patient for each anxiety disorder
Treatment
Behavioral: breathing retraining—involves teaching patients rhythmic abdominal breathing; helps to make patients feel more in control of their anxiety; cognitive restructuring—patients get anxious because they engage in catastrophic thinking and overestimate probability of occurrence of event; need to restructure thought processes to ease anxiety
Pharmacotherapy: selective serotonin reuptake inhibitors (SSRIs)—start with lower dose than usually recommended and slowly titrate up; starting doses cause increased anxiety in patient with anxiety disorder; patients more sensitive to side effects from medications; start patient on one-half of smallest dose available; recommend treating patient for 1 yr; studies show SSRIs can increase risk for suicidal behavior in children and adolescents with psychiatric disorders; consider risk for suicide when treating children or adolescents with any antidepressant; antidepressants can cause behavioral toxicity, resulting in increased anxiety; side effects include sexual dysfunction (eg, decreased libido, difficulty achieving orgasm), headaches, irritability, nausea, and insomnia (mild and transient); benzodiazepines—enhance action of neurotransmitter γ-aminobutyric acid (GABA); produce sense of calm in patients within minutes; potential for abuse, especially in patients who abuse other drugs (eg, methamphetamine, cocaine) or alcohol; can help patients understand connection between anxiety and experiences; dualaction reuptake inhibitors—venlafaxine (Effexor) and duloxetine (Cymbalta); mechanism of action involves serotonin and norepinephrine; effective in treating anxiety, but not more effective than SSRI; can cause hypertension (monitor blood pressure); other psychotropics— β-blockers useful in treating performance anxiety; mood stabilizers second- or third-line treatment of anxiety disorders; clonidine used to treat children with anxiety (associated with rebound hypertension); buspirone (BuSpar) safe and effective in treating GAD; mirtazapine (Remeron) effective in reducing anxiety but associated with somnolence and weight gain
DEPRESSION —A. Evan Eyler, MD, MPH, Associate Professor, Family Medicine and Psychiatry, Associate Residency Director, and Director, Behavioral Sciences, Department of Family Medicine, University of Vermont College of Medicine, Burlington
Outpatient evaluation: initial evaluation—determine whether patient depressed or going through life turmoil (not necessarily depression); determine when depressive symptoms started; check whether patient had previous episode of depression and outcome of that episode; consider using diagnostic criteria of specific instrument to diagnose depression (eg, Patient Health Questionnaire-9 [PHQ-9]); consider other diagnoses, eg, adjustment disorder; discuss with patient risks and benefits of treatment with antidepressants (Food and Drug Administration [FDA] currently more focused on antidepressant risks); document diagnosis and reasons for diagnosis, and indicate risks and benefits of antidepressant medications discussed with patient; differential diagnosis—determine type of depression; need to distinguish unipolar depression from bipolar disorder or depression with psychotic features; look for evidence of mood elevation now or in past; determine whether patient has or has had psychotic symptoms; determine whether substances contribute to presentation; consider whether patient chronically dysregulated (eg, personality disorder present); questions to ask patients include “has there ever been a time when you felt just the opposite of the way you do now?” and “have you ever been so depressed that it caused a perceptual distortion and made you see or hear things that weren’t there?”; if considering diagnosis of bipolar disorder, document history and consider consultation; mood swings not necessarily suggestive of bipolar disorder; antidepressant treatment can cause hypomania or manic episode to occur in patient with bipolar disorder; consider prescribing bupropion if possibility of cycling; general medical evaluation—document illnesses, medication use, use of illicit substances, and use of herbs; consider use of stimulant medication along with antidepressant in patient who has severe medical illness with depressive symptoms; history—ask about previous suicide attempts or near-suicide attempts, past substance abuse treatment (or if treatment needed), past psychiatric treatment (check for medications and response or problems, psychotherapy or programs, or hospitalizations); safety evaluation—assess patient for suicidal or violent ideation, intent, or plans; determine whether patient has access to means to commit suicide, especially guns; check for presence of psychotic symptoms, command hallucinations, and severe anxiety; ask patient about substance use and past attempts or near attempts at suicide; determine whether family history of suicide or recent exposure to suicide present; determine whether crisis evaluation needed; evaluation of functional status—criteria for involuntary hospitalization in most states involve inability to meet basic needs or determination that person danger to themselves or others; “basic needs” not well defined; assess patient for ability to work, care for children, meet medical needs, and whether support available
Treatment: choices—consider medication or therapy (alone or combined) in mild depression; consider medication and therapy (if patient able to participate) in patients with moderate to severe depression; if patient has severe depression with psychotic features or bipolar disorder, consider medication, electroconvulsive therapy (ECT), and psychotherapy when patient able; therapy as primary modality—consider if patient preference, if previous response positive, significant psychosocial stressors, interpersonal difficulties, intrapsychic conflict, comorbid personality disorder, or if patient pregnant, lactating, plans pregnancy, or has high chance of pregnancy; medication as primary modality—consider patient preference, previous positive response, lack of available alternative modalities, significant sleep or appetite disturbance or agitation, severe symptoms present, or if need for maintenance therapy anticipated; improving medication response— once-daily or bid regimen; low cost; optimism on part of patient that medication effective in relieving symptoms and if reasonably tolerant of side effects; warn patient that response may take up to 1 mo, and to keep taking medications even when feeling better; ask patient to notify physician before stopping medication, especially if patient taking selective serotonin/norepinephrine reuptake inhibitor (SNRI); also inform patient where and how to call if he or she experiences problems; unipolar depression—SSRIs, SNRIs (venlafaxine and duloxetine), norepinephrine and dopamine reuptake inhibitors (NDRI; bupropion), and noradrenergic and specific serotonergic antidepressants (NaSSA; mirtazapine); consider combining bupropion with SSRI when patient not getting enough benefit from SSRI alone; bupropion somewhat activating, and all 3 of major neurotransmitters stimulated with combination of bupropion and SSRI; consider switching between groups if patient not experiencing enough symptom relief; consider combining SSRIs in some patient; recommend SSRI if patient has comorbid anxiety disorder, if patient medically ill (eg, myocardial infarction, stroke), has chronic fatigue, or experiences premature ejaculation; avoid using SSRI with tricyclic antidepressant (TCA); bupropion—consider if minor cycling risk, if patient has attention-deficit/hyperactivity disorder (ADHD), or if patient discontinued SSRI because of sexual dysfunction; avoid in patient with eating disorder, seizure disorder, history of traumatic brain injury, agitation, withdrawal, or hepatic disease; mirtazapine—not associated with sexual dysfunction; consider use if SSRI becomes ineffective over time, if psychotic symptoms present, or if patient has no appetite or insomnia; avoid in patient with bipolar disorder, or hepatic or renal risks; neutropenia rare side effect; venlafaxine—consider if patient needs energy boost or fast onset; use with caution in patients with hypertension, bipolar disorder, cardiac history, or history of unreliable use or discontinuation of medication; duloxetine—avoid in patient with history of abrupt discontinuation of medication; consider in patient with erratic use of medication; watch for interactions between medications, especially SSRI and TCA, and fluoxetine with other drugs metabolized via cytochrome P450 2D6 pathway; risk factors for recurrence—recommend keeping patient with persistent dysthymia or who had multiple prior major depressive episodes on medication longer
Warnings and cautions: suicide risks—discuss with patients those antidepressant medications associated with increased risk for suicide, and advise them to seek help immediately if thoughts of suicide occur; document discussion; document that patient evaluated for bipolar disorder and warned about activation with medication use; discuss risks with responsible caregiver if patient young or infirm and document discussion; atypical antipsychotics—record baseline weight, body mass index, blood pressure, blood glucose, and lipid profile in patients given (or who may require) atypical antipsychotics, and follow these patients closely for changes in these levels; discuss with patient possibility of metabolic syndrome, appetite stimulation, weight gain, and diabetes and document this discussion; paroxetine—FDA determined exposure in first trimester of pregnancy may increase risk for congenital malformations; changed from category C to category D; duloxetine—FDA increased precautions about potential for hepatotoxicity; ask patients about previous liver disease and alcohol use before prescribing this drug; check transaminase levels in patients taking duloxetine; prostaglandin E2 (PGE2) inhibitors—uncommon but documented association with rare cases of nonarteric anterior ischemic optic neuropathy (NAION); advise patients who experience sudden or decreased vision loss to seek help; dextromethorphan—serious threat to adolescents because of potential for abuse; ask about over-the-counter (OTC) medications during substance histories
