Anxiety

Anxiety is an emotion characterized 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.

Anxiety vs. fear
Anxiety is distinguished from fear, which is an appropriate cognitive and emotional response to a perceived threat. Fear is related to the specific behaviors of fight-or-flight responses, defensive behavior or escape. There is a false presumption that often circulates that anxiety only occurs in situations perceived as uncontrollable or unavoidable, but this is not always so. David Barlow defines anxiety as "a future-oriented mood state in which one is not ready or prepared to attempt to cope with upcoming negative events," and that it is a distinction between future and present dangers which divides anxiety and fear. Another description of anxiety is agony, dread, terror, or even apprehension. In positive psychology, anxiety is described as the mental state that results from a difficult challenge for which the subject has insufficient coping skills. Fear and anxiety can be differentiated into four domains: (1) duration of emotional experience, (2) temporal focus, (3) specificity of the threat, and (4) motivated direction. Fear is short-lived, present-focused, geared towards a specific threat, and facilitates escape from threat. On the other hand, anxiety is long-acting, future-focused, broadly focused towards a diffuse threat, and promotes excessive caution while approaching a potential threat and interferes with constructive coping. Joseph E. LeDoux and Lisa Feldman Barrett have both sought to separate automatic threat responses from additional associated cognitive activity within anxiety. == Evolutionary perspectives ==
Evolutionary perspectives
Evolutionary psychiatry and evolutionary psychology interpret anxiety as an evolved defenses that helps organisms avoid potential threats; by design, such defenses can produce "false alarms" when the cost of a missed danger would be high (sometimes described as a "smoke‑detector" principle). Contemporary reviews stress that this framing does not treat anxiety disorders as adaptive, but rather as dysregulations or context‑insensitive activation of otherwise useful systems; the perspective is used for explanation and psychoeducation, not as a specific therapy. ==Symptoms==
Symptoms
Anxiety can be experienced with long, drawn-out daily symptoms that reduce quality of life, known as chronic (or generalized) anxiety, or it can be experienced in short spurts with sporadic, stressful panic attacks, known as acute anxiety. Symptoms of anxiety can range in number, intensity, and frequency, depending on the person. However, most people do not suffer from chronic anxiety. Anxiety can induce several psychological pains (e.g., depression) or mental disorders, and may lead to self-harm or suicide. It may also include a feeling of helplessness. The cognitive effects of anxiety may include thoughts about suspected dangers, such as an irrational fear of dying or having a heart attack, when in reality, all one is experiencing is mild chest pain, for example. The physiological symptoms of anxiety may include: • Neurological, as headache, paresthesia, fasciculations, vertigo, or presyncope. • Digestive, as abdominal pain, nausea, diarrhea, indigestion, dry mouth, or globus. Stress hormones released in an anxious state have an impact on bowel function and can manifest physical symptoms that may contribute to or exacerbate IBS. • Respiratory, as shortness of breath or sighing breathing. • Cardiac, as palpitations, tachycardia, or chest pain. • Muscular, as fatigue, tremors, or tetany. • Cutaneous, as perspiration, or itchy skin. • Uros-genital, as frequent urination, urinary urgency, dyspareunia, or impotence, chronic pelvic pain syndrome. ==Types==
Types
There are various types of anxiety. Existential anxiety can occur when a person faces angst, an existential crisis, or nihilistic feelings. People can also face mathematical anxiety, somatic anxiety, stage fright, or test anxiety. Social anxiety refers to a fear of rejection and negative evaluation (being judged) by other people. The theologian Paul Tillich characterized existential anxiety as "the state in which a being is aware of its possible nonbeing", and he listed three categories for the nonbeing and resulting anxiety: ontic (fate and death), moral (guilt and condemnation), and spiritual (emptiness and meaninglessness). According to Tillich, the last of these three types of existential anxiety is predominant in modern times, while the others were predominant earlier. Tillich argues that spiritual anxiety can either be accepted as part of the human condition or resisted with negative consequences. In its pathological form, it may "drive the person toward the creation of certitude in systems of meaning which are supported by tradition and authority" even though such "undoubted certitude is not built on the rock of reality". According to Viktor Frankl, the author of ''Man's Search for Meaning'', when a person is faced with extreme mortal dangers, the most basic of all human wishes is to find a meaning of life to combat the "trauma of nonbeing" as death is near. Depending on the source of the threat, psychoanalytic theory distinguishes three types of anxiety: realistic, neurotic and moral. Test, performance, and competitive Test According to the Yerkes-Dodson law, an optimal level of arousal is necessary to best complete a task such as an exam, performance, or competitive event. However, when the anxiety or level of arousal exceeds that optimum, the result is a decline in performance. Test anxiety is the uneasiness, apprehension, or nervousness felt by students who have a fear of failing an exam. Students who have test anxiety may experience any of the following: the association of grades with personal worth; fear of embarrassment by a teacher; fear of alienation from parents or friends; time pressures; or feeling a loss of control. Sweating, dizziness, headaches, racing heartbeats, nausea, fidgeting, uncontrollable crying or laughing and drumming on a desk are all common. Because test anxiety hinges on fear of negative evaluation, debate exists as to whether test anxiety is itself a unique anxiety disorder or whether it is a specific type of social phobia. The DSM-IV classifies test anxiety as a type of social phobia. Research indicates that test anxiety among U.S. high-school and college students has been rising since the late 1950s. Test anxiety remains a challenge for students, regardless of age, and has considerable physiological and psychological impacts. Management of test anxiety focuses on achieving relaxation and developing mechanisms to manage anxiety. The routine practice of slow, Device-Guided Breathing (DGB) is a major component of behavioral treatments for anxiety conditions. Performance and competitive Performance anxiety and competitive anxiety (competitive trait anxiety, competitive state anxiety) happen when an individual's performance is measured against others. An important distinction between competitive and non-competitive anxiety is that competitive anxiety makes people view their performance as a threat. As a result, they experience a drop in their ordinary ability, whether physical or mental, due to that perceived stress. Competitive anxiety is caused by a range of internal factors, including high expectations, outside pressure, It commonly occurs in those participating in high-pressure activities like sports and debates. Some common symptoms of competitive anxiety include muscle tension, fatigue, weakness, a sense of panic, apprehensiveness, and panic attacks. There are 4 major theories of how anxiety affects performance: Drive theory, Inverted U theory, Reversal theory, and The Zone of Optimal Functioning theory. Drive theory believes that anxiety is positive and performance improves proportionally to the level of anxiety. This theory is not well accepted. The Inverted U theory is based on the idea that performance peaks at a moderate stress level. It is called Inverted U theory because the graph that plots performance against anxiety looks like an inverted "U". Stranger, social, and intergroup anxiety Humans generally require social acceptance and thus sometimes dread the disapproval of others. Apprehension of being judged by others may cause anxiety in social environments. Anxiety during social interactions, particularly between strangers, is common among young people. It may persist into adulthood and become social anxiety or social phobia. "Stranger anxiety" in small children is not considered a phobia. In adults, an excessive fear of other people is not a developmentally common stage; it is called social anxiety. According to Cutting, social phobic do not fear the crowd but the fact that they may be judged negatively. Social anxiety varies in degree and severity. For some people, it is characterized by experiencing discomfort or awkwardness during physical social contact (e.g. embracing, shaking hands, etc.), while in other cases it can lead to a fear of interacting with unfamiliar people altogether. Those with this condition may restrict their lifestyles to accommodate the anxiety, minimizing social interaction whenever possible. Social anxiety also forms a core aspect of certain personality disorders, including avoidant personality disorder. To the extent that a person is fearful of social encounters with unfamiliar others, some people may experience anxiety particularly during interactions with outgroup members, or people who share different group memberships (i.e., by race, ethnicity, class, gender, etc.). Depending on the nature of the antecedent relations, cognitions, and situational factors, intergroup contact may be stressful and lead to feelings of anxiety. This apprehension or fear of contact with outgroup members is often called interracial or intergroup anxiety. As is the case with the more generalized forms of social anxiety, intergroup anxiety has behavioral, cognitive, and affective effects. For instance, increases in schematic processing and simplified information processing can occur when anxiety is high. Indeed, such is consistent with related work on attentional bias in implicit memory. Additionally recent research has found that implicit racial evaluations (i.e. automatic prejudiced attitudes) can be amplified during intergroup interaction. Negative experiences have been illustrated in producing not only negative expectations, but also avoidant, or antagonistic, behavior such as hostility. Furthermore, when compared to anxiety levels and cognitive effort (e.g., impression management and self-presentation) in intragroup contexts, levels and depletion of resources may be exacerbated in the intergroup situation. Trait Anxiety can be either a short-term "state" or a long-term "personality trait". Trait anxiety reflects a stable tendency across the lifespan of responding with acute, state anxiety in the anticipation of threatening situations (whether they are actually deemed threatening or not). A meta-analysis showed that a high level of neuroticism is a risk factor for development of anxiety symptoms and disorders. Such anxiety may be conscious or unconscious. Personality can also be a trait leading to anxiety and depression and their persistence. Choice or decision Anxiety induced by the need to choose between similar options is recognized as a problem for some individuals and for organizations. In 2004, Capgemini wrote: "Today we're all faced with greater choice, more competition and less time to consider our options or seek out the right advice." Overthinking a choice is called analysis paralysis. In a decision context, unpredictability or uncertainty may trigger emotional responses in anxious individuals that systematically alter decision-making. There are primarily two forms of this anxiety type. The first form refers to a choice in which there are multiple potential outcomes with known or calculable probabilities. The second form refers to the uncertainty and ambiguity related to a decision context in which there are multiple possible outcomes with unknown probabilities. Someone with panic disorder will eventually develop constant fear of another attack and as this progresses it will begin to affect daily functioning and an individual's general quality of life. It is reported by the Cleveland Clinic that panic disorder affects 2 to 3 percent of adult Americans and can begin around the time of the teenage and early adult years. Some symptoms include: difficulty breathing, chest pain, dizziness, trembling or shaking, feeling faint, nausea, fear that you are losing control or are about to die. Even though they have these symptoms during an attack, the main symptom is the persistent fear of having future panic attacks. == Anxiety disorders ==
Anxiety disorders
Anxiety disorders are a group of mental disorders characterized by exaggerated feelings of anxiety and fear responses. To be diagnosed, symptoms typically need to be present for at least six months, be more than would be expected for the situation, and decrease a person's ability to function in their daily lives. Other problems that may result in similar symptoms include hyperthyroidism, heart disease, caffeine, alcohol, or cannabis use, and withdrawal from certain drugs, among others. Without treatment, anxiety disorders tend to remain. Treatment may include lifestyle changes, counselling, and medications. About 12% of people are affected by an anxiety disorder in a given year and between 12% and 30% are affected at some point in their life. They occur about twice as often in women than they do in men, and generally begin before the age of 25. The most common anxiety disorders are specific phobias, which affect nearly 12% of people, and social anxiety disorder, which affects 10% of people at some point in their life.
