Agoraphobia [1] is a mental and behavioral disorder, [5] specifically an anxiety disorder characterized by symptoms of anxiety in situations where the person perceives their environment to be unsafe with no easy way to escape. [1] These situations can include public transit, shopping centers, crowds and queues, or simply being outside their home on their own. [1] Being in these situations may result in a panic attack. [2] Those affected will go to great lengths to avoid these situations. [1] In severe cases, people may become completely unable to leave their homes. [2]
Agoraphobia is believed to be due to a combination of genetic and environmental factors. The condition often runs in families, and stressful or traumatic events such as the death of a parent or being attacked may be a trigger. [1] In the DSM-5, agoraphobia is classified as a phobia along with specific phobias and social phobia. [1] [3] Other conditions that can produce similar symptoms include separation anxiety, post-traumatic stress disorder, and major depressive disorder. [1] The diagnosis of agoraphobia has been shown to be comorbid with depression, substance abuse, and suicide ideation. [6] [7]
Without treatment, it is uncommon for agoraphobia to resolve. [1] Treatment is typically with a type of counselling called cognitive behavioral therapy (CBT). [3] [8] CBT results in resolution for about half of people. [4] In some instances, those with a diagnosis of agoraphobia have reported taking benzodiazepines and antipsychotics. [6] Agoraphobia affects about 1.7% of adults. [1] Women are affected about twice as often as men. The condition is rare in children, often begins in adolescence or early adulthood, and becomes more common at age 65 or above. [1]
The term agoraphobia was coined in German in 1871 by pioneering German psychologist Karl Friedrich Otto Westphal (1833–1890), in his article "Die Agoraphobie, eine neuropathische Erscheinung". Archiv für Psychiatrie und Nervenkrankheiten, Berlin, 1871–72; 3: 138–161. It is derived from Greek ἀγορά (agorā́), meaning ' place of assembly ' or 'market-place' and -φοβία (-phobía), meaning 'fear'. [9] [10]
Agoraphobia is a condition where individuals become anxious in unfamiliar environments or where they perceive that they have little control. Triggers for this anxiety may include wide-open spaces, crowds (social anxiety), or traveling (even short distances). Agoraphobia is often, but not always, compounded by a fear of social embarrassment, as a person experiencing agoraphobia fears the onset of a panic attack and appearing distraught in public. Most of the time they avoid these areas and stay in the comfort of a known, controllable space, usually their home. [1]
Agoraphobia is also defined as "a fear, sometimes terrifying, by those who have experienced one or more panic attacks". [11] In these cases, the patient is fearful of a particular place because they have previously experienced a panic attack at the same location. Fearing the onset of another panic attack, the patient is fearful or avoids a location. Some refuse to leave their homes in medical emergencies because the fear of being outside of their comfort areas is too great. [12]
The person with this condition can sometimes go to great lengths to avoid the locations where they have experienced the onset of a panic attack. Agoraphobia, as described in this manner, is a symptom professionals check when making a diagnosis of panic disorder. Other syndromes like obsessive–compulsive disorder or post-traumatic stress disorder can also cause agoraphobia. Any irrational fear that keeps one from going outside can cause the syndrome. [13]
People with agoraphobia may experience temporary separation anxiety disorder when certain individuals of the household depart from the residence temporarily, such as a parent or spouse, or when they are left home alone. These situations can result in an increase in anxiety or a panic attack or feeling the need to separate themselves from family or friends. [14] [15]
People with agoraphobia sometimes fear waiting outside for long periods of time; that symptom can be called "macrophobia". [16]
Agoraphobia patients can experience sudden panic attacks when traveling to places where they fear they are out of control, help would be difficult to obtain, or they could be embarrassed. During a panic attack, epinephrine is released in large amounts, triggering the body's natural fight-or-flight response. A panic attack typically has an abrupt onset, building to maximum intensity within 10 to 15 minutes, and rarely lasts longer than 30 minutes. [17] Symptoms of a panic attack include palpitations, rapid heartbeat, sweating, trembling, nausea, vomiting, dizziness, tightness in the throat, and shortness of breath. Many patients report a fear of dying, fear of losing control of emotions, or fear of losing control of behaviors. [17]
Agoraphobia is believed to be due to a combination of genetic and environmental factors. The condition often runs in families, and stressful or traumatic events such as the death of a parent or being attacked may be a trigger. [1]
Research has uncovered a link between agoraphobia and difficulties with spatial orientation. [18] [19] Individuals without agoraphobia are able to maintain balance by combining information from their vestibular system, their visual system, and their proprioceptive sense. A disproportionate number of agoraphobics have weak vestibular function and consequently rely more on visual or tactile signals. They may become disoriented when visual cues are sparse (as in wide-open spaces) or overwhelming (as in crowds). [20] Likewise, they may be confused by sloping or irregular surfaces. [20]
In a virtual reality study, agoraphobics showed impaired processing of changing audiovisual data in comparison with subjects without agoraphobia. [21]
Chronic use of tranquilizers and sleeping pills such as benzodiazepines has been linked to onset of agoraphobia. [22] In 10 patients who had developed agoraphobia during benzodiazepine dependence, symptoms abated within the first year of assisted withdrawal. [23] Similarly, alcohol use disorders are associated with panic with or without agoraphobia; this association may be due to the long-term effects of alcohol consumption causing a distortion in brain chemistry. [24]
Tobacco smoking has also been associated with the development and emergence of agoraphobia, often with panic disorder; it is uncertain how tobacco smoking results in anxiety-panic with or without agoraphobia symptoms, but the direct effects of nicotine dependence or the effects of tobacco smoke on breathing have been suggested as possible causes. Self-medication or a combination of factors may also explain the association between tobacco smoking and agoraphobia and panic. [25]
Some scholars [26] [27] have explained agoraphobia as an attachment deficit, i.e., the temporary loss of the ability to tolerate spatial separations from a secure base. [28] Recent empirical research has also linked attachment and spatial theories of agoraphobia. [29]
In the social sciences, a perceived clinical bias [30] exists in agoraphobia research. Branches of the social sciences, especially geography, have increasingly become interested in what may be thought of as a spatial phenomenon. One such approach links the development of agoraphobia with modernity. [31] Factors considered contributing to agoraphobia within modernity are the ubiquity of cars and urbanization. These have helped develop the expansion of public space and the contraction of private space, thus creating a conflict in the mind of agoraphobic individuals.
An evolutionary psychology view is that the more unusual primary agoraphobia without panic attacks may be due to a different mechanism from agoraphobia with panic attacks. Primary agoraphobia without panic attacks may be a specific phobia explained by it once having been evolutionarily advantageous to avoid exposed, large, open spaces without cover or concealment. Agoraphobia with panic attacks may be an avoidance response secondary to the panic attacks, due to fear of the situations in which the panic attacks occurred. [32] [33]
Most people who present to mental health specialists develop agoraphobia after the onset of panic disorder. [34] Agoraphobia is best understood as an adverse behavioral outcome of repeated panic attacks and subsequent anxiety and preoccupation with these attacks that leads to an avoidance of situations where a panic attack could occur. [35] Early treatment of panic disorder can often prevent agoraphobia. [36] Agoraphobia is typically determined when symptoms are worse than panic disorder, but also do not meet the criteria for other mental disorders such as depression. [37]
Agoraphobia without a history of panic disorder (also called primary agoraphobia) is an anxiety disorder where the individual with the diagnosis does not meet the DSM-5 criteria for panic disorder. Agoraphobia typically develops as a result of having panic disorder. In a small minority of cases, however, agoraphobia can develop by itself without being triggered by the onset of panic attacks. Agoraphobia can be caused by traumatic experiences, such as bullying or abuse. Historically, there has been debate over whether agoraphobia without panic genuinely existed, or whether it was simply a manifestation of other disorders such as panic disorder, generalized anxiety disorder, avoidant personality disorder and social phobia. One researcher said: "out of 41 agoraphobics seen (at a clinic) during a period of 1 year, only 1 fit the diagnosis of agoraphobia without panic attacks, and even this particular classification was questionable...Do not expect to see too many agoraphobics without panic". [38] In spite of this earlier skepticism, current thinking is that agoraphobia without panic disorder is indeed a valid, unique illness which has gone largely unnoticed, since those with the condition are far less likely to seek clinical treatment.[ citation needed ]
According to the DSM-IV-TR, a widely-used manual for diagnosing mental disorders, the condition is diagnosed when agoraphobia is present without panic disorder where symptoms are not caused by or are unreasonable to an underlying medical problem or pharmacological influence. [39] The DSM-5 decoupled agoraphobia and panic disorder, making them separate disorders that can be diagnosed together. [40]
Systematic desensitization can provide lasting relief to the majority of patients with panic disorder and agoraphobia. The disappearance of residual and sub-clinical agoraphobic avoidance, and not simply of panic attacks, should be the aim of exposure therapy. [41] Many patients can deal with exposure easier if they are in the company of a friend on whom they can rely. [42] [43] In this approach, it is suggested that people being treated remain in the situation that provokes anxiety until the symptoms anxiety have subsided because if they leave the situation, the phobic response will not decrease and it may even rise. [43]
A related exposure treatment is in vivo exposure, a cognitive behavioral therapy method, that gradually exposes patients to the feared situations or objects. [44] This treatment was largely effective with an effect size from d = 0.78 to d = 1.34, and these effects were shown to increase over time, proving that the treatment had long-term efficacy (up to 12 months after treatment). [44]
Psychological interventions in combination with pharmaceutical treatments were overall more effective than treatments simply involving either CBT or pharmaceuticals. Further research showed there was no significant effect between using group CBT versus individual CBT. [44]
Cognitive restructuring has also proved useful in treating agoraphobia. [45] This treatment involves coaching a participant through a dianoetic discussion, with the intent of replacing irrational, counterproductive beliefs with more factual and beneficial ones. [45]
Relaxation techniques are often useful skills for the agoraphobic to develop, as they can be used to stop or prevent symptoms of anxiety and panic. [46]
Videoconferencing psychotherapy (VCP) is an emerging modality used to treat various disorders in a remote method. [47] Similar to traditional face-to-face interventions, VCP can be used to administer CBT. [48]
Virtual reality computer stimulated therapy has been suggested to help people with psychosis and agoraphobia manage their avoidance of outside environments. In the therapy, the user wears a headset and a virtual character provides psychological advice and guides them as they explore simulated environments (such as a cafe or a busy street). [49]
Antidepressant medications most commonly used to treat anxiety disorders are mainly selective serotonin reuptake inhibitors. Benzodiazepines, monoamine oxidase inhibitor, and tricyclic antidepressants are also sometimes prescribed for treatment of agoraphobia. [50] Antidepressants are important because some have anxiolytic effects. Antidepressants should be used in conjunction with exposure as a form of self-help or with cognitive behaviour therapy. [43] A combination of medication and cognitive behaviour therapy is sometimes the most effective treatment for agoraphobia. [43]
Eye movement desensitization and reprocessing (EMDR) has been studied as a possible treatment for agoraphobia, with poor results. [51] As such, EMDR is only recommended in cases where cognitive-behavioral approaches have proven ineffective or in cases where agoraphobia has developed following trauma. [52]
Many people with anxiety disorders benefit from joining a self-help or support group (telephone conference-call support groups or online support groups being of particular help for completely housebound individuals). Sharing problems and achievements with others, as well as sharing various self-help tools, are common activities in these groups. In particular, stress management techniques and various kinds of meditation practices and visualization techniques can help people with anxiety disorders calm themselves and may enhance the effects of therapy, as can service to others, which can distract from the self-absorption that tends to go with anxiety problems. Also, preliminary evidence suggests aerobic exercise may have a calming effect. Since caffeine, certain illicit drugs, and even some over-the-counter cold medications can aggravate the symptoms of anxiety disorders, they should be avoided. [53]
Agoraphobia occurs about twice as commonly among women as it does in men. It can develop at any age but is much more common in adolescence and early adulthood and occurs more often in people of above average intelligence. [54]
Panic disorder with or without agoraphobia affects roughly 5.1% of Americans, [44] and about 1/3 of this population with panic disorder have co-morbid agoraphobia. It is uncommon to have agoraphobia without panic attacks, with only 0.17% of people with agoraphobia not presenting panic disorders as well. [44]
Anxiety is an emotion characterised by an unpleasant state of inner turmoil and includes feelings of dread over anticipated events. Anxiety is different from fear in that fear is defined as the emotional response to a present threat, whereas anxiety is the anticipation of a future one. It is often accompanied by nervous behavior such as pacing back and forth, somatic complaints, and rumination.
A phobia is an anxiety disorder, defined by an irrational, unrealistic, persistent and excessive fear of an object or situation. Phobias typically result in a rapid onset of fear and are usually present for more than six months. Those affected go to great lengths to avoid the situation or object, to a degree greater than the actual danger posed. If the object or situation cannot be avoided, they experience significant distress. Other symptoms can include fainting, which may occur in blood or injury phobia, and panic attacks, often found in agoraphobia and emetophobia. Around 75% of those with phobias have multiple phobias.
Anxiety disorders are a group of mental disorders characterized by significant and uncontrollable feelings of anxiety and fear such that a person's social, occupational, and personal functions are significantly impaired. Anxiety may cause physical and cognitive symptoms, such as restlessness, irritability, easy fatigue, difficulty concentrating, increased heart rate, chest pain, abdominal pain, and a variety of other symptoms that may vary based on the individual.
Panic attacks are sudden periods of intense fear and discomfort that may include palpitations, otherwise defined as a rapid, irregular heartbeat, sweating, chest pain or discomfort, shortness of breath, trembling, dizziness, numbness, confusion, or a sense of impending doom or loss of control. Typically, these symptoms are the worst within ten minutes of onset and can last for roughly 30 minutes, though they can vary anywhere from seconds to hours. While they can be extremely distressing, panic attacks themselves are not physically dangerous.
Specific phobia is an anxiety disorder, characterized by an extreme, unreasonable, and irrational fear associated with a specific object, situation, or concept which poses little or no actual danger. Specific phobia can lead to avoidance of the object or situation, persistence of the fear, and significant distress or problems functioning associated with the fear. A phobia can be the fear of anything.
Hypochondriasis or hypochondria is a condition in which a person is excessively and unduly worried about having a serious illness. Hypochondria is an old concept whose meaning has repeatedly changed over its lifespan. It has been claimed that this debilitating condition results from an inaccurate perception of the condition of body or mind despite the absence of an actual medical diagnosis. An individual with hypochondriasis is known as a hypochondriac. Hypochondriacs become unduly alarmed about any physical or psychological symptoms they detect, no matter how minor the symptom may be, and are convinced that they have, or are about to be diagnosed with, a serious illness.
Avoidant personality disorder (AvPD) or anxious personality disorder is a Cluster C personality disorder characterized by excessive social anxiety and inhibition, fear of intimacy, severe feelings of inadequacy and inferiority, and an overreliance on avoidance of feared stimuli as a maladaptive coping method. Those affected typically display a pattern of extreme sensitivity to negative evaluation and rejection, a belief that one is socially inept or personally unappealing to others, and avoidance of social interaction despite a strong desire for it. It appears to affect an approximately equal number of men and women.
Taijin kyofusho is a Japanese culture-specific syndrome. The term taijin kyofusho translates into the disorder (sho) of fear (kyofu) of interpersonal relations (taijin). Those who have taijin kyofusho are likely to be extremely embarrassed about themselves or fearful of displeasing others when it comes to the functions of their bodies or their appearances. These bodily functions and appearances include their faces, odor, actions, or looks. They do not want to embarrass other people with their presence. This culture-bound syndrome is a social phobia based on fear and anxiety.
Psychogenic non-epileptic seizures (PNES), also referred to as pseudoseizures, non-epileptic attack disorder (NEAD), functional seizures, or dissociative seizures, are episodes resembling an epileptic seizure but without the characteristic electrical discharges associated with epilepsy. PNES fall under the category of disorders known as functional neurological disorders (FND) and are typically treated by psychologists or psychiatrists.
Mysophobia, also known as verminophobia, germophobia, germaphobia, bacillophobia and bacteriophobia, is a pathological fear of contamination and germs. It is classified as a type of specific phobia, meaning it is evaluated and diagnosed based on the experience of high levels of fear and anxiety beyond what is reasonable when exposed to or in anticipation of exposure to stimuli related to the particular concept. William A. Hammond first coined the term in 1879 when describing a case of obsessive–compulsive disorder (OCD) exhibited in repeatedly washing one's hands.
Mental health professionals often distinguish between generalized social phobia and specific social phobia. People with generalized social phobia have great distress in a wide range of social situations. Those with specific social phobia may experience anxiety only in a few situations. The term "specific social phobia" may also refer to specific forms of non-clinical social anxiety.
Social anxiety is the anxiety and fear specifically linked to being in social settings. Some categories of disorders associated with social anxiety include anxiety disorders, mood disorders, autism spectrum disorders, eating disorders, and substance use disorders. Individuals with higher levels of social anxiety often avert their gazes, show fewer facial expressions, and show difficulty with initiating and maintaining a conversation. Social anxiety commonly manifests itself in the teenage years and can be persistent throughout life; however, people who experience problems in their daily functioning for an extended period of time can develop social anxiety disorder. Trait social anxiety, the stable tendency to experience this anxiety, can be distinguished from state anxiety, the momentary response to a particular social stimulus. Half of the individuals with any social fears meet the criteria for social anxiety disorder. Age, culture, and gender impact the severity of this disorder. The function of social anxiety is to increase arousal and attention to social interactions, inhibit unwanted social behavior, and motivate preparation for future social situations.
Thalassophobia is the persistent and intense fear of deep bodies of water, such as the ocean, seas, or lakes. Though related, thalassophobia should not be confused with aquaphobia, which is classified as the fear of water itself. Thalassophobia can include fears of being in deep bodies of water, the vastness of the sea, sea waves, aquatic animals, and great distance from land.
Obsessive–compulsive disorder (OCD) is a mental and behavioral disorder in which an individual has intrusive thoughts and feels the need to perform certain routines (compulsions) repeatedly to relieve the distress caused by the obsession, to the extent where it impairs general function.
Mixed anxiety–depressive disorder (MADD) is a diagnostic category that defines patients who have both anxiety and depressive symptoms of limited and equal intensity accompanied by at least some autonomic nervous system features. Autonomic features are involuntary physical symptoms usually caused by an overactive nervous system, such as panic attacks or intestinal distress. The World Health Organization's ICD-10 describes Mixed anxiety and depressive disorder: "...when symptoms of anxiety and depression are both present, but neither is clearly predominant, and neither type of symptom is present to the extent that justifies a diagnosis if considered separately. When both anxiety and depressive symptoms are present and severe enough to justify individual diagnoses, both diagnoses should be recorded and this category should not be used."
Interoceptive exposure is a cognitive behavioral therapy technique used in the treatment of panic disorder. It refers to carrying out exercises that bring about the physical sensations of a panic attack, such as hyperventilation and high muscle tension, and in the process removing the patient's conditioned response that the physical sensations will cause an attack to happen.
Social anxiety disorder (SAD), also known as social phobia, is an anxiety disorder characterized by sentiments of fear and anxiety in social situations, causing considerable distress and impairing ability to function in at least some aspects of daily life. These fears can be triggered by perceived or actual scrutiny from others. Individuals with social anxiety disorder fear negative evaluations from other people.
Panic disorder is a mental and behavioral disorder, specifically an anxiety disorder characterized by reoccurring unexpected panic attacks. Panic attacks are sudden periods of intense fear that may include palpitations, sweating, shaking, shortness of breath, numbness, or a feeling that something terrible is going to happen. The maximum degree of symptoms occurs within minutes. There may be ongoing worries about having further attacks and avoidance of places where attacks have occurred in the past.
Fear of flying is the fear of being on a flying vehicle, such as an airplane or helicopter, while it is in flight. It is also referred to as flying anxiety, flying phobia, flight phobia, aviophobia, aerophobia, or pteromerhanophobia.
Autophobia, also called monophobia, isolophobia, or eremophobia, is the specific phobia or a morbid fear or dread of oneself or of being alone, isolated, abandoned, and ignored. This specific phobia is associated with the idea of being alone, often causing severe anxiety.
