"The fight-or-flight system is hardwired for us humans to manage dangerous situations, and those of us with anxiety have an activated fight-or-flight response when the trigger is not really dangerous," says Beth Salcedo, MD, the medical director of The Ross Center for Anxiety & Related Disorders and board president of the Anxiety and Depression Association of America.
An anxiety attack can be described as a sudden attack of fear, terror, or feelings of impending doom that strike without warning and for no apparent reason. This strong sensation or feeling can also be accompanied by a number of other symptoms, including pounding heart, rapid heart rate, sweating, lightheadedness, nausea, hot or cold flashes, chest pain, hands and feet may feel numb, tingly skin sensations, burning skin sensations, irrational thoughts, fear of losing control, and a number of other symptoms. (While other symptoms often do accompany anxiety attacks, they don’t necessarily have to.)
Furthermore, certain organic diseases may present with anxiety or symptoms that mimic anxiety. These disorders include certain endocrine diseases (hypo- and hyperthyroidism, hyperprolactinemia), metabolic disorders (diabetes), deficiency states (low levels of vitamin D, B2, B12, folic acid), gastrointestinal diseases (celiac disease, non-celiac gluten sensitivity, inflammatory bowel disease), heart diseases, blood diseases (anemia), cerebral vascular accidents (transient ischemic attack, stroke), and brain degenerative diseases (Parkinson's disease, dementia, multiple sclerosis, Huntington's disease), among others.
There are long-term, biological, environmental, and social causes of panic attacks. In 1993, Fava et al. proposed a staging method of understanding the origins of disorders. The first stage in developing a disorder involves predisposing factors, such as genetics, personality, and a lack of wellbeing. Panic disorder often occurs in early adulthood, although it may appear at any age. It occurs more frequently in women and more often in people with above-average intelligence. Various twin studies where one identical twin has an anxiety disorder have reported a 31–88% incidence of the other twin also having an anxiety disorder diagnosis.
Simple Phobias and Agoraphobia: People with panic disorder often develop irrational fears of specific events or situations that they associate with the possibility of having a panic attack. Fear of heights and fear of crossing bridges are examples of simple phobias. As the frequency of panic attacks increases, the person often begins to avoid situations in which they fear another attack can occur or places where help would not be immediately available. This avoidance may eventually develop into agoraphobia, an inability to go beyond known and safe surroundings because of intense fear and anxiety. Generally, these fears can be resolved through repeated exposure to the dreaded situations, while practicing specific techniques to become less sensitive to them.

Panic attacks are often confusing for the sufferer. They are usually sudden and are accompanied by extremely intense physical sensations, leaving one to believe they may have a serious medical condition. Because the physical symptoms associated with a panic attack are similar to certain serious medical conditions, it is important to rule out any medical causes.
If you think a friend or colleague at work is experiencing an anxiety disorder or other mental health difficulty, you should carefully consider how you react. Your actions in the workplace can have work-related and legal consequences. However, intervening early before an emergency situation arises can help prevent greater consequences for your colleague's career, health, and safety.
Anxiety is distinguished from fear, which is an appropriate cognitive and emotional response to a perceived threat. Anxiety is related to the specific behaviors of fight-or-flight responses, defensive behavior or escape. It occurs in situations only perceived as uncontrollable or unavoidable, but not realistically 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.
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.
If you're having lots of panic attacks at unpredictable times and there doesn't seem to be a particular trigger or cause, you might be given a diagnosis of panic disorder. It's common to experience panic disorder and agoraphobia (a type of phobia) together. People who experience panic disorder may have some periods with few or no panic attacks, but have lots at other times.
Anxiety attacks can last anywhere between a few moments to 30 or more minutes. It’s also common for subsequent anxiety attacks to follow, causing the overall anxiety attack experience to last much longer as one episode is followed by another. Even though anxiety attacks eventually end, it’s common for the symptoms and after effects of an anxiety attack to linger for hours or even days, depending upon the severity of the attack and the level of stress your body is under.
Anxiety attacks that occur while sleeping, also called nocturnal panic attacks, occur less often than panic attacks during the daytime but affect about 40%-70% of those who suffer from daytime panic attacks. This symptom is also important because people who suffer from panic symptoms during sleep tend to have more respiratory distress associated with their panic. They also tend to experience more symptoms of depression and other psychiatric disorders compared to people who do not have panic attacks at night. Nocturnal panic attacks tend to cause sufferers to wake suddenly from sleep in a state of sudden fear or dread for no apparent reason. In contrast to people with sleep apnea and other sleep disorders, sufferers of nocturnal panic can have all the other symptoms of a panic attack. The duration of nocturnal panic attacks tends to be less than 10 minutes, but it can take much longer to fully calm down for those who experience them.
An evolutionary psychology explanation is that increased anxiety serves the purpose of increased vigilance regarding potential threats in the environment as well as increased tendency to take proactive actions regarding such possible threats. This may cause false positive reactions but an individual suffering from anxiety may also avoid real threats. This may explain why anxious people are less likely to die due to accidents.
These physiological responses can actually help us to survive. However, sometimes we experience these physiological responses, like an increased heartbeat, that are not in the presence of danger at all, but something else entirely. In these cases, our bodies can misinterpret these physiological signals as being indicators of danger or a "true threat." For example, people may experience learned anxiety due to previous associations between elevated heart rate and panic attacks and may misinterpret bodily sensations as signs of imminent death or loss of control. In this way, one may start to fear these physiological responses, which is what we call "fear of fear" (Craske & Barlow, 2007). "Fear of fear" maintains or perpetuates panic attacks and panic symptoms, which becomes a vicious cycle. In other words, you experience an increased heart rate, which you interpret as negative, which makes you feel anxious, which further makes your heart rate increase and it often spirals from there. These associations may almost happen automatically, even without conscious thought, but this is what is likely going on behind the scenes.
Several drugs can cause or worsen anxiety, whether in intoxication, withdrawal or from chronic use. These include alcohol, tobacco, cannabis, sedatives (including prescription benzodiazepines), opioids (including prescription pain killers and illicit drugs like heroin), stimulants (such as caffeine, cocaine and amphetamines), hallucinogens, and inhalants. While many often report self-medicating anxiety with these substances, improvements in anxiety from drugs are usually short-lived (with worsening of anxiety in the long term, sometimes with acute anxiety as soon as the drug effects wear off) and tend to be exaggerated. Acute exposure to toxic levels of benzene may cause euphoria, anxiety, and irritability lasting up to 2 weeks after the exposure.
Panic attacks are extremely unpleasant and can be very frightening. As a result, people who experience repeated panic attacks often become very worried about having another attack and may make changes to their lifestyle so as to avoid having panic attacks. For example, avoiding exercise so as to keep their heart rate low, or avoiding certain places.
The feared object/situation is avoided or endured with intense anxiety or distress. 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.
The philosopher Søren Kierkegaard, in The Concept of Anxiety (1844), described anxiety or dread associated with the "dizziness of freedom" and suggested the possibility for positive resolution of anxiety through the self-conscious exercise of responsibility and choosing. In Art and Artist (1932), the psychologist Otto Rank wrote that the psychological trauma of birth was the pre-eminent human symbol of existential anxiety and encompasses the creative person's simultaneous fear of – and desire for – separation, individuation, and differentiation.
Anxiety can be either a short-term "state" or a long-term "trait". Whereas trait anxiety represents worrying about future events, anxiety disorders are a group of mental disorders characterized by feelings of anxiety and fear. Anxiety disorders are partly genetic but may also be due to drug use, including alcohol, caffeine, and benzodiazepines (which are often prescribed to treat anxiety), as well as withdrawal from drugs of abuse. They often occur with other mental disorders, particularly bipolar disorder, eating disorders, major depressive disorder, or certain personality disorders. Common treatment options include lifestyle changes, medication, and therapy. Metacognitive therapy seeks to diminish anxiety through reducing worry, which is seen[by whom?] as a consequence of metacognitive beliefs.
Please Note: In some cases, children, teenagers, and young adults under 25 may experience an increase in suicidal thoughts or behavior when taking antidepressant medications, especially in the first few weeks after starting or when the dose is changed. Because of this, patients of all ages taking antidepressants should be watched closely, especially during the first few weeks of treatment.
