    This has resulted in the implementation of uniform treatment regimens in primary care 25 and in the development of the unified theory of anxiety. Understanding how emotional reactivity, core beliefs, and coping strategies interact in time should lead to more precise diagnoses and better management of anxiety disorders. We recently applied a mathematical model using nonlinear dynamics to describe these processes 27 and further developed this model to cover diagnostic presentations and their underlying processes.

    In this model, a variety of triggering events can elicit responses at the levels of A larm sensations, B eliefs, and associated C oping ABC strategies, including behaviors. Each of these processes originates in discrete brain circuits that are functionally connected. Over time, this perpetuates a vicious circle, shaping the presentation of a variety of anxiety disorders. Alarms A are emotional sensations or physiological reactions to a trigger situation, sensation, or thought.

    A well-defined set of brain circuits rapidly processes information about the alarm. The ensuing decision to act is made on the basis of beliefs B that rely heavily on previous experiences, personal and cultural background, and the information that is perceived by the sensory organs.

    Patients with anxiety disorders appear to process information about a supposedly dangerous situation with more focused attention compared with individuals without the disorder. These processes evolve over time, forming a complex picture of a particular anxiety disorder. This event activates circuits that process information about danger and, when coupled with personal beliefs about the event, leads to increased concern about personal health and safety.

    This in turn leads to a specific attempt to decrease the danger of the situation e. Unfortunately, because no absolute safety is to be found, these behaviors become more extensive and chronic in the attempt to alleviate anxiety. The fact that anxiety persists induces more worry and eventually distress, thus perpetuating the vicious circle of the disorder recurrent panic attacks.

    If the pattern is uninterrupted, it eventually leads to even more inappropriate coping behavior, such as avoidance of any potential triggers of panic agoraphobia , and can result in comorbid despair and depression.

    Most of the anxiety disorders follow this process even though different stages may predominate in different disorders; that is, ritualistic behavior is more characteristic of OCD, and avoidance predominates in social anxiety disorder.

    We have found that patients quickly recognize and interpret their symptom patterns within the ABC model. We effectively incorporate this pattern with medication and behavioral techniques, as described in the previous studies. Using this model, residents are able to understand and to begin administering cognitive—behavioral therapy CBT within relatively few sessions.

    In order to treat an anxiety disorder effectively, clinicians should understand how these conditions emerge and which factors are involved in maintaining them. In recent years, we have gained a better understanding of the interplay between genetic, biological, and stress factors that shape the presentation of the disorder, although it is not clear which factors are inherited.

    One possibility is that abnormal cognition could be the inherited factor. Most cognitive strategies for treatment and research were developed in earlier years.

    The ABC model focuses on the interaction of information processing and emotional and cognitive processes that are controlled by overlapping circuits and compete for the same brain resources. In most anxiety disorders, patients usually process fear-inducing information in excessive detail that overwhelms their ability to appraise it properly.

    As a result, they consider the worst-case scenario i. Stress also plays a major role in the pathology of anxiety disorders. For example, PTSD is a condition in which stress is considered the main etiological factor, although there is a high degree of co-occurring stress reported by these patients.

    Nevertheless, patients with any anxiety disorder often pinpoint the onset of their disorder in relation to a striking stressful event or to a continuous persistent stressor. Whether a cause or a consequence, increased stress reactivity sometimes accounts for relapses in chronic anxiety conditions like GAD.

    According to some studies, a stressful event or a persistent and chronic disorder can even cause secondary biological changes in specific brain structures. Although stressors are separately identified along Axis IV of the multiaxial system, the context for the patient is unclear.

    With this approach, we might be better able to capture the landscape and dynamic of the stress. For example, panic disorder resulting from exposure to catastrophic combat may differ clinically from panic disorder that results from a persistent work-related stress or separation from family. Exploration of how stress affects biology and the course of anxiety disorders is clearly needed. Biological factors are of primary importance in anxiety disorders.

    Anxiety disorders can occur in the context of medical illness, 33 and the clinician should consider an intricate relationship between medical illnesses and anxiety disorders. This relationship could be manifold. First, metabolic or autonomic abnormalities caused by the illness can produce the syndrome of anxiety i. The symptom of medical illness can be a trigger for anxiety i. Sometimes medical illness can mimic the anxiety disorder i. Finally, medical illness and an anxiety disorder can simply coexist in the same patient.

    One of the most interesting interactions between medical illness and anxiety disorders is pediatric autoimmune neuropsychiatric disorder associated with streptococcal infections PANDAS , which has been reported in a subset of OCD patients.

    Over the previous two decades, the main thrust of biological research in anxiety disorders has shifted from peripheral measures of autonomic and neurochemical parameters to identifying reactivity and neurochemistry of the living brain directly through advances in neuroimaging technology. Anxiety disorders are an appropriate target for neuroimaging research because it is easy to provoke specific symptoms in many cases.

    Much of the research on neural circuits has focused on models of anxiety and fear proposed earlier by basic scientists, 35 , 36 and a synthesis of current data has been attempted for panic disorder 37 and OCD. There have been some excellent reviews of neuroimaging experiments in anxiety, 39 , 40 but the picture remains incomplete, in part because of a lack of clinical trials addressing the long-term integration of threat responses.

    As in the dynamical model, every anxiety disorder may be viewed as an interplay of anxious feelings, abnormal processing of information, and inadequate coping strategies. In accordance with this model of anxiety, overlapping neuronal circuits are responsible for alarm reactions, processing of perceived threats, and behavioral coping see Figure 1. This model attempts to simplify complex brain circuitry that needs to be studied over the next several decades before we can truly understand how the brain processes threats over time.

    For simplicity we identify Alarm circuits A , in which the amygdala is the structure of primary importance. These circuits also include periaqueductal gray matter and multiple nuclei in the brainstem. These circuits are possibly responsible for the quick response to a threat. Abnormalities in Coping C should be governed by distributed cortical networks and are difficult to tease apart.

    Thus, a convenient mnemonic explaining these circuits could be A Alarm, amygdala , B Beliefs, basal ganglia , and C Coping, cortex. Neuronal circuits are governed by multiple neurotransmitter systems; the most extensive of these are gamma-aminobutyric acid GABA and glutamate.

    The neural systems of the three major neurotransmitter systems—serotonin, dopamine, and norepinephrine—have been extensively studied in normal and pathological anxiety states. However, anxiety disorders are not simply a deficiency of one neurotransmitter or another. The networks governed by these transmitters have extensive interrelationships, multiple feedback mechanisms, and complex receptor structures.

    Research involving other neurotransmitter systems has been fruitful in elucidating their function in anxiety but thus far has failed to produce new treatments. The primary neurotransmitter and receptor systems implicated in the pathogenesis of anxiety disorders are discussed next. The primary serotonergic pathways originate in the raphe nuclei and project widely to numerous targets throughout the forebrain. There are also numerous serotonin receptor subtypes whose roles may vary, depending on location.

    For example, the serotonin-1a receptor serves as both a mediator and an inhibitor of serotonergic neurotransmission, depending on whether it is located on the presynaptic or the postsynaptic neuron. Despite this complexity, it is recognized that medications that inhibit the reuptake of serotonin, presumably increasing serotonergic neurotransmission, result in a reduction in symptoms of anxiety for many patients.

    Increases in GABA neurotransmission mediate the anxiolytic effect of barbiturates and benzodiazepines. Although modulation of GABA-ergic pathways can reduce anxiety almost immediately, compensatory mechanisms associated with these circuits and the use of barbiturates and benzodiazepines can result in tolerance and potentially fatal withdrawal.

    Anticonvulsant agents also alter GABA transmission and are used to treat anxiety. The principal dopaminergic pathways originate from the midbrain in the ventral tegmental area and substantia nigra, with projections to the cortex, striatum, limbic nuclei, and infundibulum.

    This class of medications has been widely used in the treatment of anxiety. However, as a catecholamine, dopamine is up-regulated with norepinephrine in anxiety states, whereas increases in dopaminergic signaling also appear to mediate feelings of self-efficacy and confidence—which can act to reduce anxiety.

    Some patients with anxiety disorder respond well to pro-dopaminergic drugs such as bupropion Wellbutrin, GlaxoSmithKline ; other patients find that such agents exacerbate their symptoms. Noradrenergic neurons originate primarily in the locus coeruleus in the pons and project widely throughout the CNS. Many of the physiological symptoms of anxiety are mediated by norepinephrine, and antagonists of various norepinephrine receptor subtypes are used to combat particular aspects of anxiety.

    For example, propranolol, an antagonist of the beta 2 -norepinephrine receptor, is used to reduce the rapid heart rate, hand tremor, and quivering voice that might accompany public speaking or other activities associated with performance anxiety. Similarly, prazosin Minipress, Pfizer , an antagonist of the alpha 1 -norepinephrine receptor, is used to reduce the intensity and frequency of nightmares associated with PTSD but has not been effective in relieving other symptoms of anxiety disorders.

    Glutamate is the primary excitatory neurotransmitter in the CNS and is involved in virtually every neuronal pathway, including those underlying normal and pathological anxiety states. Activation of the NMDA receptor triggers protein synthesis, which appears to strengthen the connection between neurons when they fire concurrently. Therefore, glutamatergic pathways are probably involved in both conditioning and extinction, the processes associated with the development and treatment of anxiety disorders, respectively.

    Preliminary evidence suggests that both augmentation and antagonism of NMDA-mediated pathways are effective in the treatment of anxiety disorders, although no glutamatergic medications have received an FDA indication for this use.

    Many other neurotransmitter systems participate in the biological mechanisms of fear and anxiety. Neuropeptides, including substances P, N, and Y; corticotropin-releasing factor CRF ; cannabinoids; and others, modulate fear in animal models. Numerous neurotransmitters play a role in normal states and in pathological anxiety states.

    Each of these systems is a potential target for pharmacological intervention, but relatively few classes of medications are used in clinical practice for the treatment of anxiety.

    These drug classes are briefly discussed next. SSRIs, usually indicated in depression, are considered to be the first line of therapy for anxiety disorders. The mechanism by which this leads to amelioration of anxiety symptoms is not fully understood. Vilazodone, the most recently approved medication in this class although indicated for major depressive disorder , also acts as a partial agonist at the serotonin-1a receptor, which may contribute to anxiolysis.

    SNRIs, which inhibit the serotonin and norepinephrine transporters, include venlafaxine, desvenlafaxine Pristiq, Pfizer , and duloxetine. They are used in place of augmentation to SSRIs because the combination of these two drug classes may result in serotonin syndrome. Patient responses to SNRIs can vary widely; some patients may experience an exacerbation of the physiological symptoms of anxiety as a result of the increased norepinephrine-mediated signaling caused by inhibition of the norepinephrine transporter.

    For patients who do not experience this effect, the increased noradrenergic tonus may contribute to the anxiolytic efficacy of these medications. Although benzodiazepines were widely used in the past to treat anxiety conditions, they are no longer considered to be first-line therapies because of the risks associated with their chronic use. For these reasons, the use of benzodiazepines is often restricted to the short-term treatment of acute anxiety or as therapy for refractory anxiety after failed trials of several other drugs.

    Of note, some subgroups of patients do well with low doses of benzodiazepines and are able to safely taper from high doses, especially when cognitive—behavioral therapy CBT is added. Because of the side effects of benzodiazepines, antiepileptic agents have been used more extensively for the treatment of anxiety. Antiseizure drugs were initially used for mood stabilization in mood disorders; however, their anxiolytic properties were quickly noted.

    Many agents in this drug class are being used in an off-label fashion to treat anxiety, especially gabapentin Neurontin, Pfizer and pregabalin Lyrica, Pfizer. All tricyclic antidepressants TCAs function as norepinephrine reuptake inhibitors, and several mediate serotonin reuptake inhibition as well.

    Although several medications in this drug class are comparable in efficacy to the SSRIs or SNRIs for anxiety disorders, TCAs carry a greater number of adverse effects and are potentially lethal in an overdose. For this reason, TCAs are rarely used in the treatment of anxiety disorders. Hydroxyzine Atarax, Pfizer , mirtazapine Remeron, Organon , nefazodone Bristol-Myers Squibb , and atypical neuroleptic agents are commonly used to treat anxiety.

    Hydroxyzine is indicated for anxiety and probably achieves anxiolysis by inhibiting the histamine H 1 receptor and the serotonin-2a receptor. During the s, mainstream psychological and pharmacological treatments of anxiety disorders were developed and tested, leading to an initial algorithm that is similar for all major anxiety disorders. Adapted from Roy-Byrne, et al. Arch Gen Psychiatry ;62[3]: None of the SSRIs has shown superiority to another. The choice of an SSRI is usually based on the side-effect profile, pharmacokinetic and pharmacodynamic properties, and potential interactions with coadministered medications.

    Several excellent reviews of SSRI therapies for anxiety disorders have been published. Antidepressants with broader mechanisms of action i. The rationale for this practice is that these medications affect more than one neurotransmitter system and have some, albeit weak, meta-analytic data supporting their superiority in depression and OCD. Few data have been published about what to do after the few initial steps of treatment, such as how long maintenance therapy should last.

    Based on clinical experience, we generally recommend continuing treatment until the patient has achieved marked symptom reduction for at least 6 months. More research on this topic is needed. Further testing of combined treatments at the initial and later steps of the typical algorithm was subsequently performed.

    Atypical neuroleptic medications have shown even better evidence of efficacy in anxiety disorders, according to some placebo-controlled trials. Patients and physicians need to be aware of adverse drug reactions. Because polypharmacy is becoming the rule rather than the exception, especially in complex and treatment-resistant anxiety, practitioners should be cognizant of potential drug—drug interactions.

    Serotonin syndrome and neuroleptic malignant syndromes, although rare, should be kept in mind. Symptoms may include paresthesias, nonvertiginous dizziness, nausea, diaphoresis, and rebound anxiety. CBT has received the greatest amount of empirical support for the psychological treatment of anxiety disorders.

    Combining drug therapy and CBT has shown mixed results in favoring one approach over the other, depending on the type of anxiety disorder. A review and meta-analysis approached the question of combination treatment over monotherapy or CBT in anxiety by hypothesizing that CBT would be more successful compared with medications; however, the medication held an advantage over CBT in depression.

    By contrast, patients with social anxiety disorder were more responsive to medication. The choice of medication or CBT, alone or in combination, is based on several variables, including the availability of a therapist; the affordability of CBT, which costs more than medication, especially if drugs are prescribed in primary care settings; and patient preference. It is generally acknowledged that the treatment of anxiety disorders is suboptimal because of a lack of CBT therapists or the availability of affordable sessions.

    There is a great need to distill the essence of good therapy and to bring it into the primary care setting, with an emphasis on education and staff training. Their work suggested that even self-administered treatment might be an effective addition to the CBT armamentarium. Although many treatments are effective for anxiety, not all of them can help everyone and not all of them are effective for all anxiety disorders.

    A simple phobia is easier to treat than a complicated case of PTSD. Relapse rates for CBT, compared with medication, are an understudied area, although our clinical experience suggests that CBT has a longer treatment effect if the patient continues to use the skills and tools learned in therapy. CBT shares much in common with other more dynamically based forms of psychotherapy.

    A patient seeks help from an expert caregiver who treats the patient in a warm and nonjudgmental relationship in an attempt to help the patient function and feel better in a reality-oriented setting. The helping relationship is less emphasized in CBT as a curative factor, but it is considered important in building trust and support, serving as a springboard for patients to consider their erroneous beliefs and behaviors that cause them anxiety and fear.

    The therapist often incorporates manuals or other psychoeducational materials and may propose daily homework to help the patient learn more adaptive ways to manage and reduce the alarm A , change irrational and dysfunctional beliefs B , and develop adaptive coping C mechanisms, often through exposure exercises.

    To the most appropriate extent possible, patients are taught the ABC model to help them understand the dynamic and reciprocal relationship among feelings, thoughts, and behaviors. Motivational interviewing, which is used to help patients examine the cost—benefit ratio of their maladaptive thoughts and behavior, often increases compliance and, subsequently, effectiveness.

    Although beliefs are the linchpin, exposure to the anxiety-producing thought, image, or situation is often the essential CBT component for jogging the linchpin loose.

    This too is a dynamic process. Cognitive restructuring techniques aimed at reducing catastrophic thinking help to diminish irrational or exaggerated thoughts, thereby allowing patients to become more willing to test those beliefs through exercises involving exposure. Exposure is the gradual and systematic presentation of the anxiety-inducing thought, image, or situation for a long enough time for patients to see that their anxious feelings can be decreased without engaging in avoidance or escape.

    For example, a patient who is afraid of dogs might first be shown a picture of a dog, then stand across the street from a pet shop, and finally hold a dog in his or her arms. The patient would engage in each of these steps repeatedly and in a concentrated but not overwhelming way.

    Ideally, the patient would experience a gradual lessening of anxiety at each step before moving on to the next. The patient would experience the alarm being reduced, and the exaggerated belief that all dogs are dangerous could be modified to a more accurate belief that most pet dogs are not threatening.

    The hoped-for outcome would be that the patient would no longer have a phobic avoidance of all dogs. A final emerging area in the evolution of CBT is the approach based on mindfulness acceptance.

    Mindfulness is a type of meditation that has been adapted from Buddhist psychology. Acceptance and commitment therapy involves a mindful focus; many exercises are aimed at the meta-cognitive level to help patients perceive their thinking and subsequent anxiety to be separate from, and less identified with, their sense of self.

    Anxiety-causing thoughts are to be observed and accepted, not to be struggled with and changed, as in more traditional CBT and Western psychological approaches. At the same time, SSRIs antidepressants are increasingly used in primary care, and physicians in fact are the largest group of prescribers.

    This is a mixed blessing for several reasons:. This state of affairs may partly explain why psychiatrists are seeing more patients who are disenchanted with numerous failed attempts at pharmacotherapy. Another problem in primary care is a lack of understanding of behavioral strategies that result in low referral rates to mental health professionals.

    There has been a trend toward developing comprehensive treatments for panic disorder to be delivered by primary care physicians. In one study, an algorithm was tested for the treatment of panic disorder. In managing refractory anxiety, it is important to start with a re-evaluation of the patient, including the diagnosis; comorbidities; and the interplay of cognitive, stress-related, and biological factors. Inadequate coping strategies on the part of patients and their family members should be reviewed.

    Doses and duration of the initial treatments should be assessed. After that, the treatment may progress to a combination of SSRIs with antiepileptic or atypical neuroleptic agents, especially if bipolar disorder or a psychotic disorder is suspected. Although other forms of therapy have not demonstrated efficacy in anxiety disorders, they may be helpful for addressing personality issues in chronically anxious patients. Therapies for anxiety disorders, beyond combining conventional treatments, using off-label antiepileptic and antipsychotic agents, and introducing more intensive CBT programs, are mostly experimental.

    Promising medications have included intravenous clomipramine, citalopram, and morphine. A handful of invasive therapies have emerged. These options may be considered after several off-label pharmacotherapy and psychotherapeutic approaches have failed or when significant functional impairment remains. They are typically reserved for the most treatment-resistant cases, typically those involving severe OCD. Invasive treatments often target brain circuits implicated in the processing of fear and anxiety.

    Electroconvulsive therapy ECT involves the application of brief electrical impulses to the scalp to induce large-scale cortical neuronal discharges, eventually producing generalized seizure activity.

    Although ECT is effective in treatment-resistant mood disorders, data regarding its efficacy in anxiety disorders are limited. Initially developed as an antiepileptic treatment, vagal nerve stimulation VNS was used in psychiatric patients after sustained mood improvements were noted with this therapy.

    This modality is not routinely used to treat anxiety, and evidence of its effectiveness in resistant anxiety disorders is limited. Focal magnetic stimulation of the scalp is used with the goal of invoking excitation or inhibition of cortical neurons. Repetitive transcranial magnetic stimulation rTMS is less invasive than ECT; anesthesia induction is not required, and rTMS does not elicit generalized seizure activity in the brain.

    It also has the advantage of being able to target brain regions thought to be involved in anxiety disorders. The main limitations of rTMS include the inability to penetrate deeper brain structures implicated in OCD the caudate nucleus, thalamus, and anterior capsule fiber tracts or in panic disorder the amygdala, hippocampus, and anterior cingulate ; there is also a lack of specificity at the site of stimulation.

    There is limited evidence for efficacy in treating OCD, although larger treatment effects have been reported by altering the stimulation site. A small study reported significant anxiety reductions in patients with generalized anxiety disorder GAD using a symptom-provocation task during functional magnetic resonance imaging fMRI to guide individual selection of the rTMS site.

    Although psychosurgery has been used for various treatment-resistant anxiety disorders such as GAD, panic disorder, and social phobia, long-term follow-up studies in these patients have revealed adverse cognitive outcomes, including apathy and frontal lobe dysfunction.

    Several surgical approaches have been used, including anterior capsulotomy which targets the anterior limb of the internal capsule , anterior cingulotomy which targets the anterior cingulate and cingulum bundle , subcaudate tractotomy which targets the substantia innominata, just inferior to the caudate nucleus , and limbic leucotomy which combines anterior cingulotomy with subcaudate tractotomy. Cingulotomy remains the most commonly used psychosurgical procedure in North America, probably because of its clinical efficacy as well as low morbidity and mortality rates.

    Postsurgical effects have included transient headache, nausea, or difficulty urinating. Patient outcomes cannot be fully assessed until at least 6 months to 2 years after the definitive procedure, suggesting that postoperative neural reorganization plays an important role in recovery.

    Direct comparisons of each lesion approach within studies are rare. Overall, the long-term outcomes of these approaches have demonstrated significant therapeutic effects of each procedure. The major advantage of DBS over ablative surgery is the ability to adjust and customize neurostimulation. Parameters can be optimized by a specially trained clinician during long-term follow-up.

    Several studies with blinded stimulation have been conducted with moderate-to-fair results. Batteries must also be periodically explanted and replaced. Stimulation-related side effects have been reported, including mood changes transient sadness, anxiety, euphoria, and hypomania , sensory disturbances olfactory, gustatory, and motor sensations , and cognitive changes confusion and forgetfulness.

    These side effects are typically stimulation-dependent and disappear after the stimulation parameters are altered. During the s, many alternative treatment strategies for anxiety disorders emerged. These treatments may be provided by alternative medicine practitioners within the scope of a health care model, such as acupuncture, homeopathy, Ayurvedic medicine, Reiki, and healing touch. Because of minimal FDA regulation and widespread over-the-counter availability, many of these same treatments are self-selected and used by patients.

    Herbs are the most commonly used complementary and alternative medicine CAM products and are particularly popular with those with psychiatric disorders. Anxiety is one of the strongest predictors of herbal remedy utilization, and patients often use these treatments without the knowledge of their physician. Consequently, clinicians and pharmacists are advised to regularly monitor the full range of treatments used by their patients, including a thorough medication reconciliation of prescription and non-prescription products, herbs, and supplements at each visit.

    Results of herbal trials for anxiety disorders have been mixed. The widespread use of Piper methysticum Kava for anxiolysis was curtailed by reports of hepatotoxicity, prompting government warnings and withdrawal of the product from the market in many Western countries. Despite a lack of data on efficacy, many patients continue to use CAM therapies, prompting a need to monitor use for potential interactions with prescription medications.

    Milk thistle inhibits CYP3A4 and has the potential to increase levels of other medications metabolized by this pathway. Although many patients with anxiety disorders experience symptom relief with treatment, residual symptoms still have an impact on everyday functions. Even subclinical anxiety can produce disability sometimes exceeding that seen in other severe mental illnesses. Yet there are few clear interventions or programs with a focus on rehabilitation and restoration of function in these patients.

    Stress is an important factor in the emergence and maintenance of anxiety syndromes. Patients who need to return to the workforce can experience increased stress that in turn may cause re-emergence of the symptoms, again resulting in decreased productivity and even loss of employment.

    More research is needed to address this problem. Anxiety disorders are treatable. Effective treatments have been developed, and algorithms have been refined. However, more work needs to be directed toward merging of our knowledge of the biological mechanisms of anxiety with treatment in order to more accurately predict and improve treatment response.

    Dynamic models of anxiety—such as the ABC model—can be helpful in understanding the interplay between processes responsible for development and maintenance of the symptoms over time and between biological and psychological factors affecting them.

    We need to learn how to better administer existing efficacious treatments in real-world health care environments, such as in primary care, and to inform the public via media outlets. We should continue to test alternative therapies for treating and preventing anxiety disorders and to help patients whose anxiety is resistant to conventional treatments.

    All of these measures will enhance the care of patients with anxiety.
