“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.”
Antidepressants are widely used to treat anxiety disorders, such as generalized anxiety disorder, panic disorder, agoraphobia and social anxiety disorder. The most commonly prescribed medications are from the selective serotonin reuptake inhibitor (SSRI) class. They are generally effective and have few side-effects, although they do not provide immediate relief. More
Anxiety, worry, and stress are all a part of most people’s everyday lives. But simply experiencing anxiety or stress in and of itself does not mean you need to get professional help or that you have an anxiety disorder. In fact, anxiety is an important and sometimes necessary warning signal of a dangerous or difficult situation. Without anxiety, we would have no way of anticipating difficulties ahead and preparing for them.
In order to manage threatening situations, humans have evolved to experience a "fight or flight" response. As part of this response, when humans are confronted with a dangerous situation, their body mobilizes by sending blood away from their extremities (e.g. hands and feet) and into the major muscles, producing adrenaline, and increasing heart rate so that we are better equipped to fight off danger.
Expected panic attacks are those which occur when you are exposed to one of your triggers. For example, if you have a fear of flying you may have a panic attack when you board a plane. Expected panic attacks are again broken down into two categories: situationally bound (cued) in which a person is anticipating exposure to a particular trigger (as with our flying example), or situationally predisposed, in which a panic attack does not always occur when exposed to the feared situation.
Prolonged exposure therapy is a specific type of CBT used to treat PTSD and phobias. The goal of this therapy is to help patients overcome the overwhelming disstress they experience when reminded of past traumas or in confronting their fears. With the guidance of a licensed therapist, the patient is carefully reintroduced to the trauma memories or reminders. During the exposure, the therapist guides the patient to use coping techniques such as mindfulness or relaxation therapy/imagery. The goal of this therapy is to help patients realize that trauma-related memories (or phobias) are no longer dangerous and do not need to be avoided. This type of treatment usually lasts 8-16 weekly sessions.
A person with social anxiety disorder has significant anxiety and discomfort about being embarrassed, humiliated, rejected or looked down on in social interactions. People with this disorder will try to avoid the situation or endure it with great anxiety. Common examples are extreme fear of public speaking, meeting new people or eating/drinking in public. The fear or anxiety causes problems with daily functioning and lasts at least six months.
More medications are available than ever before to effectively treat anxiety disorders. These include antidepressants (SSRIs, SNRIs, Tricyclic Antidepressants, MAOIs), tranquilizers (benzodiazepines, etc.) and in some cases, anticonvulsants. A person may have to try more than one medication before finding a drug or combination of drugs that works for them. Learn more about medications.
Anxiety disorders increase one's chances for suffering from other medical illness, such as cardiovascular disorders, including obesity, heart disease and diabetes. More specifically, increased body weight and abdominal fat, high blood pressure, and greater levels of cholesterol, triglycerides, and glucose have all been linked to anxiety. While it is still unclear what causes the high co-morbidity between anxiety and bad physical health outcomes, research suggests that changes in underlying biology that is characteristic of anxiety may also facilitate the emergence for these other physical health outcomes over time. For example, changes in stress hormones, autonomic responses, as well as heightened systemic inflammation are all associated with anxiety disorders and negative health outcomes. These shared physiological states suggest a shared underlying biology and that anxiety maybe a whole-body condition.
As with most behavioral illnesses, the causes of panic attacks are many. Certainly there is evidence that the tendency to have panic attacks can sometimes be inherited. However, there is also evidence that panic may be a learned response and that the attacks can be initiated in otherwise healthy people simply given the right set of circumstances. Research into the causes of panic attacks is ongoing.
For example, a person with obsessive-compulsive disorder may experience a panic attack when their schedule or compulsions are interrupted. Individuals who struggle with specific phobias are also susceptible to panic attacks. A person with an extreme fear of heights (acrophobia) may experience a panic attack in a penthouse apartment. And for someone with generalized anxiety disorder (GAD), a condition characterized by extreme fear or worry, the unending anxiety can escalate to a panic attack. People with post-traumatic stress disorder (PTSD) have a higher incidence of panic disorder than the general population. Illness or traumatic events increase the chances of panic attacks.
Poverty and low education level tend to be associated with anxiety, but it is unclear if those factors cause or are caused by anxiety. While some statistics suggest that disadvantaged ethnic minorities tend to suffer from internalizing disorders like panic disorder less often than the majority population in the United States, other research shows that may be the result of differences in how ethnic groups interpret and discuss signs and symptoms of intense fright, like panic attacks. Also, panic and other anxiety disorders are thought to persist more for some ethnic minorities in the United States. Difficulties the examiner may have in appropriately recognizing and understanding ethnic differences in symptom expression is also thought to play a role in ethnic differences in the reported frequency of panic and other internalizing disorders.
Antidepressants called selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) are commonly used as first-line treatments for anxiety. Less-commonly used — but effective — treatments for anxiety disorders are older classes of antidepressants, such as tricyclic antidepressants and monoamine oxidase inhibitors (MAOIs).
