Anxiety disorders and anxiolytics

This chapter will provide a brief overview of anxiety disorders and their treatments. Included here are descriptions of how the anxiety disorder subtypes overlap with each other and with major depressive disorder. Clinical descriptions and formal criteria for how to diagnose anxiety disorder subtypes are mentioned only in passing. The reader should consult standard reference sources for this material. The discussion here will emphasize how discoveries about the functioning of various brain circuits and neurotransmitters – especially those centered on the amygdala – impact our understanding of fear and worry, symptoms that cut across the entire spectrum of anxiety disorders.

The goal of this chapter is to acquaint the reader with ideas about the clinical and biological aspects of anxiety disorders in order to understand the mechanisms of action of the various treatments for these disorders discussed along the way. Many of these treatments are extensively discussed in other chapters. For details of mechanisms of anxiolytic agents used also for the treatment of depression (i.e., certain antidepressants), the reader is referred to Chapter 7; for those anxiolytic agents used also for chronic pain (i.e., certain anticonvulsants), the reader is referred to Chapter 10. The discussion in this chapter is at the conceptual level, and not at the pragmatic level. The reader should consult standard drug handbooks (such as Stahl's Essential Psychopharmacology: the Prescriber's Guide) for details of doses, side effects, drug interactions, and other issues relevant to the prescribing of these drugs in clinical practice.

Symptom dimensions in anxiety disorders

When is anxiety an anxiety disorder?

Anxiety is a normal emotion under circumstances of threat and is thought to be part of the evolutionary “fight or flight” reaction of survival. Whereas it may be normal or even adaptive to be anxious when a saber-tooth tiger (or its modern-day equivalent) is attacking, there are many circumstances in which

Figure 9-1. Overlap of major depressive disorder and anxiety disorders. Although the core symptoms of anxiety disorders (anxiety and worry) differ from the core symptoms of major depression (loss of interest and depressed mood), there is considerable overlap among the rest of the symptoms associated with these disorders (compare the “anxiety disorders” puzzle on the right to the “MDD” puzzle on the left). For example, fatigue, sleep difficulties, and problems concentrating are common to both types of disorders.

the presence of anxiety is maladaptive and constitutes a psychiatric disorder. The idea of anxiety as a psychiatric disorder is evolving rapidly, and is characterized by the concept of core symptoms of excessive fear and worry (symptoms at the center of anxiety disorders in Figure 9-1), compared to major depression, which is characterized by core symptoms of depressed mood or loss of interest (symptoms at the center of major depressive disorder in Figure 9-1).

Anxiety disorders have considerable symptom overlap with major depression (see those symptoms surrounding core features shown in Figure 9-1), particularly sleep disturbance, problems concentrating, fatigue, and psychomotor/arousal symptoms. Each anxiety disorder also has a great deal of symptom overlap with other anxiety disorders (Figures 9-2 through 9-5). Anxiety disorders are also extensively comorbid, not only with major depression, but also with each other, since many patients qualify over time for a second or even third concomitant anxiety disorder. Finally, anxiety disorders are frequently comorbid with many other conditions such as substance abuse, attention deficit hyperactivity disorder, bipolar disorder, pain disorders, sleep disorders, and more.

So, what is an anxiety disorder? These disorders all seem to maintain the core features of some form of anxiety or fear coupled with some form of worry, but their natural history over time shows them to morph from one into another, to evolve into full syndrome expression of anxiety disorder symptoms (Figure 9-1) and then to recede into subsyndromal levels of symptoms only to reappear again as the original anxiety disorder, a different anxiety disorder (Figures 9-2 through 9-5), or major depression (Figure 9-1). If anxiety disorders all share core symptoms of fear and worry (Figures 9-1 and 9-6) and, as we shall see later in this chapter, are all basically treated with the same drugs, including many of the same drugs that treat major depression, the question now arises, what is the difference between one anxiety disorder and another? Also, one could ask, what is the difference between major depression and anxiety disorders? Are all these entities really different disorders, or are they instead different aspects of the same illness?

Overlapping symptoms of major depression and anxiety disorders

Although the core symptoms of major depression (depressed mood or loss of interest) differ from the core symptoms of anxiety disorders (fear and worry), there is a great deal of overlap with the other symptoms considered diagnostic both for a major depressive episode and for several different anxiety disorders

Figure 9-2. Generalized anxiety disorder (GAD). The symptoms typically associated with GAD are shown here. These include the core symptoms of generalized anxiety and worry as well as increased arousal, fatigue, difficulty concentrating, sleep problems, irritability, and muscle tension. Many of these symptoms, including the core symptoms, are present in other anxiety disorders as well.

Figure 9-3. Panic disorder. The characteristic symptoms of panic disorder are shown here, with core symptoms of anticipatory anxiety as well as worry about panic attacks. Associated symptoms are the unexpected panic attacks themselves and phobic avoidance or other behavioral changes associated with concern over panic attacks.

(Figure 9-1). These overlapping symptoms include problems with sleep, concentration, and fatigue as well as psychomotor/arousal symptoms (Figure 9-1). It is thus easy to see how the gain or loss of just a few additional symptoms can morph a major depressive episode into an anxiety disorder (Figure 9-1) or one anxiety disorder into another (Figures 9-2 through 9-5).

From a therapeutic point of view, it may matter little what the specific diagnosis is across this spectrum of disorders (Figures 9-1 through 9-5). That is, first-line psychopharmacological treatments may not be much different for a patient who currently qualifies for a major depressive episode plus the symptom of anxiety (but not an anxiety disorder) versus a patient who currently qualifies for a major depressive episode plus a comorbid anxiety disorder with full criteria anxiety symptoms. Although it can be useful to make specific diagnoses for following patients over time and for documenting the evolution of symptoms, the emphasis from a psychopharmacological point of view is increasingly to take a symptom-based therapeutic strategy to patients with any of these disorders because the brain is not organized according to the DSM, but according to brain

Figure 9-4. Social anxiety disorder. Symptoms of social anxiety disorder, shown here, include the core symptoms anxiety or fear over social performance plus worry about social exposure. Associated symptoms are panic attacks that are predictable and expected in certain social situations as well as phobic avoidance of those situations.

Figure 9-5. Posttraumatic stress disorder (PTSD). The characteristic symptoms of PTSD are shown here. These include the core symptoms of anxiety while the traumatic event is being re-experienced as well as worry about having the other symptoms of PTSD, such as increased arousal and startle responses, sleep difficulties including nightmares, and avoidance behaviors.

circuits with topographical localization of function. That is, specific treatments can be tailored to the individual patient by deconstructing whatever disorder the patient has into a list of the specific symptoms a given patient is experiencing (see Figures 9-2 through 9-5), and then matching these symptoms to hypothetically malfunctioning brain circuits regulated by specific neurotransmitters in order to rationally select and combine psychopharmacological treatments to eliminate all symptoms and get the patient to remission.

Overlapping symptoms of different anxiety disorders

Although there are different diagnostic criteria for different anxiety disorders (Figures 9-2 though 9-5), these are constantly changing, and many do not even consider obsessive–compulsive disorder to be an anxiety disorder any longer (OCD is discussed in Chapter 14 on impulsivity). All anxiety disorders have overlapping symptoms of anxiety/fear coupled with worry (Figure 9-6). Remarkable progress has been made in

understanding the circuitry underlying the core symptom of anxiety/fear based upon an explosion of neurobiological research on the amygdala (Figures 9-7 through 9-14). The links between the amygdala, fear circuits, and treatments for the symptom of anxiety/fear across the spectrum of anxiety disorders are discussed throughout the rest of this chapter.

Worry is the second core symptom shared across the spectrum of anxiety disorders (Figure 9-7). This symptom is hypothetically linked to the functioning of cortico-striato-thalamo-cortical (CSTC) loops. The links between the CSTC circuits, “worry loops,” and treatments for the symptom of worry across the spectrum of anxiety disorders are discussed later in this chapter (see also Figures 9-15 through 9-17, 9-26, and 9-29). We shall see that what differentiates one anxiety disorder from another may not be the anatomical localization, or the neurotransmitters regulating fear and worry in each of these disorders (Figures 9-6 and 9-7), but the specific nature of malfunctioning within these same circuits in various anxiety disorders. That is, in generalized anxiety disorder (GAD), malfunctioning in the amygdala and CSTC worry loops may be hypothetically persistent, and unremitting, yet not severe (Figure 9-2), whereas malfunctioning may be theoretically intermittent but catastrophic in an unexpected manner for panic disorder (Figure 9-3) or in an expected manner for social anxiety (Figure 9-4). Circuit malfunctioning may be traumatic in origin and conditioned in posttraumatic stress disorder (PTSD: Figure 9-5).

Preface to the fourth edition

For this fourth edition of Stahl’s Essential Psychopharmacology you will notice there is a new look and feel. With a new layout, displayed over two columns, and an increased page size we have eliminated redundancies across chapters, have added significant new material, and yet have decreased the overall size of the book.

Highlights of what has been added or changed since the 3rd edition include:

Integrating much of the basic neurosciences into the clinical chapters, thus reducing the number of introductory chapters solely covering basic neurosciences.
Major revision of the psychosis chapter, including much more detailed coverage of the neurocircuitry of schizophrenia, the role of glutamate, genomics, and neuroimaging.
One of the most extensively revised chapters is on antipsychotics, which now has:
- new discussion and illustrations on how the current atypical antipsychotics act upon serotonin, dopamine, and glutamate circuitry
- new discussion of the roles of neurotransmitter receptors in the mechanisms of actions of some but not all atypical antipsychotics
  - 5HT₇ receptors
  - 5HT_2C receptors
  - α₁-adrenergic receptors
- completely revamped visuals for displaying the relative binding properties of 17 individual antipsychotics agents, based upon log binding data made qualitative and visual with novel graphics
- reorganization of the known atypical antipsychotics as
  - the “pines” (peens)
  - the “dones”
  - two “pips”
  - and a “rip”
- inclusion of several new antipsychotics
  - iloperidone (Fanapt)
  - asenapine (Saphris)
  - lurasidone (Latuda)
- extensive coverage of switching from one antipsychotic to another
- new ideas about using high dosing and polypharmacy for treatment resistance and violence
- new antipsychotics in the pipeline
  - brexpiprazole
  - cariprazine
  - selective glycine reuptake inhibitors (SGRIs, e.g., bitopertin [RG1678], Org25935, SSR103800)

The mood chapter has expanded coverage of stress, neurocircuitry, and genetics.
The antidepressant and mood stabilizer chapters have:
- new discussion and illustrations on circadian rhythms
- discussion of the roles of neurotransmitter receptors in the mechanisms of actions of some antidepressants
  - melatonin receptors
  - 5HT_1A receptors
  - 5HT_2C receptors
  - 5HT₃ receptors
  - 5HT₇ receptors
  - NMDA glutamate receptors
- inclusion of several new antidepressants
  - agomelatine (Valdoxan)
  - vilazodone (Viibryd)
  - vortioxetine (LuAA21004)
  - ketamine (rapid onset for treatment resistance)

The anxiety chapter provides new coverage of the concepts of fear conditioning, fear extinction, and reconsolidation, with OCD moved to the impulsivity chapter.
The pain chapter updates neuropathic pain states.
The sleep/wake chapter provides expanded coverage of melatonin and new discussion of orexin pathways and orexin receptors, as well as new drugs targeting orexin receptors as antagonists, such as:
- suvorexant/MK-6096
- almorexant
- SB-649868

The ADHD chapter includes new discussion on how norepinephrine and dopamine tune pyramidal neurons in prefrontal cortex, and expanded discussion on new treatments such as:
- guanfacine ER (Intuniv)
- lisdexamfetamine (Vyvanse)

The dementia chapter has been extensively revamped to emphasize the new diagnostic criteria for Alzheimer’s disease, and the integration of biomarkers into diagnostic schemes including:
- Alzheimer’s diagnostics
  - CSF Aβ and tau levels
  - amyloid PET scans, FDG-PET scans, structural MRI scans
- multiple new drugs in the pipeline targeting amyloid plaques, tangles, and tau
  - vaccines/immunotherapy (e.g., bapineuzumab, solenezumab, crenezumab), intravenous immunoglobulin
  - γ-secretase inhibitors (GSIs, e.g., semagacestat)
  - β-secretase inhibitors (e.g., LY2886721, SCH 1381252, CTS21666, others)

The impulsivity–compulsivity and addiction chapter is another of the most extensively revised chapters in this fourth edition, significantly expanding the drug abuse chapter of the third edition to include now a large number of related “impulsive–compulsive” disorders that hypothetically share the same brain circuitry:
- neurocircuitry of impulsivity and reward involving the ventral striatum
- neurocircuitry of compulsivity and habits including drug addiction and behavioral addiction involving the dorsal striatum
- “bottom-up” striatal drives and “top-down” inhibitory controls from the prefrontal cortex
- update on the neurobiology and available treatments for the drug addictions (stimulants, nicotine, alcohol, opioids, hallucinogens, and others)
- behavioral addictions
  - major new section on obesity, eating disorders, and food addiction, including the role of hypothalamic circuits and new treatments for obesity
  - lorcaserin (Belviq)
  - phentermine/topiramate ER (Qsymia)
  - bupropion/naltrexone (Contrave)
  - zonisamide/naltrexone
  - obsessive–compulsive and spectrum disorders
  - gambling, impulsive violence, mania, ADHD and many others

One of the major themes emphasized in this new edition is the notion of symptom endophenotypes, or dimensions of psychopathology that cut across numerous syndromes. This is seen perhaps most dramatically in the organization of numerous disorders of impulsivity/compulsivity, where impulsivity and/or compulsivity are present in many psychiatric conditions and thus “travel” trans-diagnostically without respecting the DSM (Diagnostic and Statistical Manual) of the American Psychiatric Association or the ICD (International Classification of Diseases). This is the future of psychiatry – the matching of symptom endophenotypes to hypothetically malfunctioning brain circuits, regulated by genes, the environment, and neurotransmitters. Hypothetically, inefficiency of information processing in these brain circuits creates symptom expression in various psychiatric disorders that can be changed with psychopharmacologic agents. Even the DSM recognizes this concept and calls it Research Domain Criteria (or RDoC). Thus, impulsivity and compulsivity can be seen as domains of psychopathology; other domains include mood, cognition, anxiety, motivation, and many more. Each chapter in this fourth edition discusses “symptoms and circuits” and how to exploit domains of psychopathology both to become a neurobiologically empowered psychopharmacologist, and to select and combine treatments for individual patients in psychopharmacology practice.

What has not changed in this new edition is the didactic style of the first three editions. This text attempts to present the fundamentals of psychopharmacology in simplified and readily readable form. We emphasize current formulations of disease mechanisms and also drug mechanisms. As in previous editions, the text is not extensively referenced to original papers, but rather to textbooks and reviews and a few selected original papers, with only a limited reading list for each chapter, but preparing the reader to consult more sophisticated textbooks as well as the professional literature.

The organization of information continues to apply the principles of programmed learning for the reader, namely repetition and interaction, which has been shown to enhance retention. Therefore, it is suggested that novices first approach this text by going through it from beginning to end, reviewing only the color graphics and the legends for those graphics. Virtually everything covered in the text is also covered in the graphics and icons. Once having gone through all the color graphics in these chapters, it is recommended that the reader then go back to the beginning of the book, and read the entire text, reviewing the graphics at the same time. After the text has been read, the entire book can be rapidly reviewed again merely by referring to the various color graphics in the book. This mechanism of using the materials will create a certain amount of programmed learning by incorporating the elements of repetition, as well as interaction with visual learning through graphics. Hopefully, the visual concepts learned via graphics will reinforce abstract concepts learned from the written text, especially for those of you who are primarily “visual learners” (i.e., those who retain information better from visualizing concepts than from reading about them). For those of you who are already familiar with psychopharmacology, this book should provide easy reading from beginning to end. Going back and forth between the text and the graphics should provide interaction. Following review of the complete text, it should be simple to review the entire book by going through the graphics once again.

Target audience

This activity has been developed for prescribers specializing in psychiatry. All other health care providers interested in psychopharmacology are welcome for advanced study, especially primary care physicians, physician assistants, nurse practitioners, psychologists, and pharmacists.

Statement of need

Psychiatric illnesses have a neurobiological basis and are primarily treated by pharmacological agents; understanding each of these, as well as the relationship between them, is essential in order to select appropriate treatment for a patient. The field of psychopharmacology has experienced incredible growth; it has also experienced a major paradigm shift from a limited focus on neurotransmitters and receptors to an emphasis as well upon brain circuits, neuroimaging, genetics, and signal transduction cascades.

The following unmet needs and professional practice gaps regarding mental health were revealed following a critical analysis of activity feedback, expert faculty assessment, literature review, and through new medical knowledge:

Mental disorders are highly prevalent and carry substantial burden that can be alleviated through treatment; unfortunately, many patients with mental disorders do not receive treatment or receive suboptimal treatment.
There is a documented gap between evidence-based practice guidelines and actual care in clinical practice for patients with mental illnesses. This gap is due at least in part to lack of clinician confidence and knowledge in terms of appropriate usage of the therapeutic tools available to them.

To help address clinician performance gaps with respect to diagnosis and treatment of mental health disorders, quality improvement efforts need to provide education regarding (1) the fundamentals of neurobiology as it relates to the most recent research regarding the neurobiology of mental illnesses; (2) the mechanisms of action of treatment options for mental illnesses and the relationship to the pathophysiology of the disease states; and (3) new therapeutic tools and research that are likely to affect clinical practice.

Learning objectives

After completing this activity, you should be better able to:

Apply fundamental principles of neurobiology to the assessment of psychiatric disease states
Differentiate the neurobiological targets for psychotropic medications
Link the relationship of psychotropic drug mechanism of action to the pathophysiology of disease states
Identify novel research and treatment approaches that are expected to affect clinical practice
