Anxiety is an emotion characterized by an unpleasant state of inner turmoil, often accompanied by nervous behaviour such as pacing back and forth, somatic complaints, and rumination. It is the subjectively unpleasant feelings of dread over anticipated events, such as the feeling of imminent death.[need quotation to verify] Anxiety is not the same as fear, which is a response to a real or perceived immediate threat, whereas anxiety involves the expectation of future threat. Anxiety is a feeling of uneasiness and worry, usually generalized and unfocused as an overreaction to a situation that is only subjectively seen as menacing. It is often accompanied by muscular tension, restlessness, fatigue and problems in concentration. Anxiety can be appropriate, but when experienced regularly the individual may suffer from an anxiety disorder.
All in a moment that may have lasted hours or seconds, everything came to a halt. The word panic doesn’t seem to reach the sensations I felt during those minutes and hours. My body ached, my insides contracted and felt ice cold, my heart hurt more than any pain I’ve felt. What was worse was the paralyzing, gripping fear—sheer and utter incapacitating fear— that I was leaving so many things undone.
People with panic attacks often report a fear of dying or heart attack, flashing vision, faintness or nausea, numbness throughout the body, heavy breathing and hyperventilation, or loss of body control. Some people also suffer from tunnel vision, mostly due to blood flow leaving the head to more critical parts of the body in defense. These feelings may provoke a strong urge to escape or flee the place where the attack began (a consequence of the "fight-or-flight response", in which the hormone causing this response is released in significant amounts). This response floods the body with hormones, particularly epinephrine (adrenaline), which aid it in defending against harm.
Although many people breathe into a paper bag in an attempt to alleviate the hyperventilation that can be associated with panic, the benefit received may be the result of the individual thinking it will help (a placebo effect). Unfortunately, breathing into a paper bag while having trouble breathing can worsen symptoms when the hyperventilation is caused by a condition associated with oxygen deprivation, like an asthma attack or a heart attack.
This disorder is characterized by panic attacks and sudden feelings of terror sometimes striking repeatedly and without warning. Often mistaken for a heart attack, a panic attack causes powerful physical symptoms including chest pain, heart palpitations, dizziness, shortness of breath and stomach upset. Many people will go to desperate measures to avoid an attack, including social isolation.
It is not unusual to experience only one or two symptoms at a time, such as vibrations in their legs, shortness of breath, or an intense wave of heat traveling up their bodies, which is not similar to hot flashes due to estrogen shortage. Some symptoms, such as vibrations in the legs, are sufficiently different from any normal sensation that they clearly indicate panic disorder. Other symptoms on the list can occur in people who may or may not have panic disorder. Panic disorder does not require four or more symptoms to all be present at the same time. Causeless panic and racing heartbeat are sufficient to indicate a panic attack.
The avoidance, anticipation of, or distress of the phobic object/situation must cause significant distress or interferes with the individual's daily life, occupational, academic, or social functioning to meet diagnosis. The symptoms cannot be better accounted for by another mental disorder or be caused by substances, medications, or medical illness.
“Panic disorder is diagnosed if the individual has recurrent panic attacks (minimum four in a four-week period), and at least one of the attacks is accompanied by one or more physical symptoms, including persistent concern about having another attack, worry about the implication or consequences of the attack (i.e., having a heart attack), and/or a significant change in behaviour due to the attacks, such as quitting a job.7 In addition, the panic attacks cannot be due to the physiological effects of a substance or another general medical condition.”
As is the case 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.
Heredity, other biological factors, stressful life events, and thinking in a way that exaggerates relatively normal bodily reactions are all believed to play a role in the onset of panic disorder. Some research suggests panic attacks occur when a “suffocation alarm mechanism” in the brain is activated, falsely reporting that death is imminent. The exact cause or causes of panic disorder are unknown and are the subject of intense scientific investigation.
Cognitive behavioral therapy focuses on the thinking patterns and behaviors that are sustaining or triggering your panic attacks and helps you look at your fears in a more realistic light. For example, if you had a panic attack while driving, what is the worst thing that would really happen? While you might have to pull over to the side of the road, you are not likely to crash your car or have a heart attack. Once you learn that nothing truly disastrous is going to happen, the experience of panic becomes less terrifying.
Cognitive therapy and exposure therapy are two CBT methods that are often used, together or by themselves, to treat social anxiety disorder. Cognitive therapy focuses on identifying, challenging, and then neutralizing unhelpful or distorted thoughts underlying anxiety disorders. Exposure therapy focuses on confronting the fears underlying an anxiety disorder to help people engage in activities they have been avoiding. Exposure therapy is sometimes used along with relaxation exercises and/or imagery.
