Evolutionary mismatch[ edit ] It has been theorized that high rates of anxiety are a reaction to how the social environment has changed from the Paleolithic era.
For example, in the Stone Age there was greater skin-to-skin contact and more handling of babies by their mothers, both of which are strategies that reduce anxiety. Researchers posit that the lack of constant social interaction, especially in the formative years, is a driving cause of high rates of anxiety. Many current cases are likely to have resulted from an evolutionary mismatch , which has been specifically termed a "psychopathogical mismatch". In evolutionary terms, a mismatch occurs when an individual possesses traits that were adapted for an environment that differs from the individual's current environment.
For example, even though an anxiety reaction may have been evolved to help with life-threatening situations, for highly sensitized individuals in Westernized cultures simply hearing bad news can elicit a strong reaction.
Simply knowing some anxiety is beneficial may alleviate some of the panic associated with mild conditions. Some researchers believe that, in theory, anxiety can be mediated by reducing a patient's feeling of vulnerability and then changing their appraisal of the situation.
A number of anxiolytics achieve their effect by modulating the GABA receptors. The basolateral complex processes sensory-related fear memories and communicates their threat importance to memory and sensory processing elsewhere in the brain, such as the medial prefrontal cortex and sensory cortices. Another important area is the adjacent central nucleus of the amygdala, which controls species-specific fear responses, via connections to the brainstem , hypothalamus , and cerebellum areas.
In those with general anxiety disorder, these connections functionally seem to be less distinct, with greater gray matter in the central nucleus. Another difference is that the amygdala areas have decreased connectivity with the insula and cingulate areas that control general stimulus salience, while having greater connectivity with the parietal cortex and prefrontal cortex circuits that underlie executive functions.
Researchers have noted "Amygdalofrontoparietal coupling in generalized anxiety disorder patients may Clinical and animal studies suggest a correlation between anxiety disorders and difficulty in maintaining balance.
SK2 potassium channels mediate inhibitory influence on action potentials and reduce arborization. By overexpressing SK2 in the basolateral amygdala, anxiety in experimental animals can be reduced together with general levels of stress-induced corticosterone secretion. LeDoux and Lisa Feldman Barrett have both sought to separate automatic threat responses from additional associated cognitive activity within anxiety.
Diagnosis[ edit ] Anxiety disorders are often severe chronic conditions, which can be present from an early age or begin suddenly after a triggering event. They are prone to flare up at times of high stress and are frequently accompanied by physiological symptoms such as headache , sweating , muscle spasms , tachycardia , palpitations , and hypertension , which in some cases lead to fatigue.
In casual discourse the words "anxiety" and "fear" are often used interchangeably; in clinical usage, they have distinct meanings: "anxiety" is defined as an unpleasant emotional state for which the cause is either not readily identified or perceived to be uncontrollable or unavoidable, whereas "fear" is an emotional and physiological response to a recognized external threat.
The fact that there is considerable overlap between symptoms of anxiety and depression, and that the same environmental triggers can provoke symptoms in either condition, may help to explain this high rate of comorbidity. The most common manifestations in individuals with anxiety disorder are avoidance of intercourse, premature ejaculation or erectile dysfunction among men and pain during intercourse among women. Sexual dysfunction is particularly common among people affected by panic disorder who may fear that a panic attack will occur during sexual arousal and posttraumatic stress disorder.
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.
There is no clear evidence as to whether therapy or medication is more effective; the choice of which is up to the person with the anxiety disorder and most choose therapy first. Adherence problems are more likely among older people, who may have difficulty understanding, seeing, or remembering instructions. These include kava , where the potential for benefit seems greater than that for harm with short-term use in those with mild to moderate anxiety. Inositol has been found to have modest effects in people with panic disorder or obsessive-compulsive disorder.
John's wort , valerian or passionflower. Family therapy is a form of treatment in which the child meets with a therapist together with the primary guardians and siblings.
We simply looked at the absolute difference in anxiety scale scores before and after treatment, without regard to the relative efficacy compared with placebo. This approach makes it possible to include hundreds of studies in comparisons of differential efficacy of all available drugs and not only the few direct head-to-head comparisons. From the patients' point of view, the improvement in anxiety symptoms as measured by the change from baseline to end point is more relevant than the difference from a control group.
The available medications for anxiety disorders showed considerably large differences in pre-post effect sizes. Quetiapine, however, is not licensed for the treatment of any anxiety disorder in most countries. However, these drugs are not recommended for routine treatment.
General treatment principles Patients must be informed about possible adverse effects, interactions, safety warnings, and contraindications, as indicated in the current summary of product characteristics. If patients are educated about the possibility that some early side effects might later decrease in intensity, compliance may improve. Patients with anxiety disorders are often hesitant to take psychotropic drugs because they are afraid of adverse effects. In particular, patients with PDA may easily discontinue antidepressants because of initial jitteriness and nervousness.
Doses for drug treatments are shown in Table II. In patients with severe hepatic impairment, a dosage adjustment or use of medications that are cleared primarily by the kidney eg, pregabalin may be required.
For all drugs recommended in this article, relapse prevention studies in at least one anxiety disorder have been conducted in patients who have responded to previous open treatment with a certain drug and were then randomized to placebo or ongoing blind treatment with the same drug for periods of between 6 and 18 months. All of these studies showed a significant advantage for staying on active medication when compared with switching to placebo.
Based on the findings from these relapse prevention studies and clinical experiences, drug treatment should be continued for 12 months or more after remission has occurred. Given the chronic course of anxiety disorders, it is regrettable that there are almost no controlled studies that investigate treatment periods over 12 months.
To avoid withdrawal syndromes, the dose should be slowly tapered off over a period of 2 weeks at treatment termination. It is a common opinion that patients treated with drugs show immediate relapse after stopping medication, whereas gains of psychological therapies are maintained for months or years after treatment termination.
This would offer psychological therapies considerable advantage over drug treatment. However, in naturalistic studies following up anxiety patients, substantial relapse rates were also found years after CBT treatment. Additive CNS depression may occur when drugs with sedating properties are combined, eg, TCAs, benzodiazepines, or pregabalin, resulting in unwanted sedation, drowsiness, or increased reaction time.
Additive effects at the neurotransmitter level can occur when medications are combined that have antagonistic effects on the same receptors, eg, two drugs with anticholinergic effects. Unresponsiveness to standard treatments Before considering a patient to be treatment unresponsive, it should be ascertained that the diagnosis was correct, adherence to the treatment plan was sufficient, the dose prescribed had covered the full range, and there had been a trial period of adequate duration.
When patients report previous treatment failures, it often turns out that a drug was only prescribed in the lowest dose or was stopped within the first 2 weeks due to side effects that occurred in the initial phase before the patient could experience improvement. Concurrent drugs may interfere with efficacy, eg, metabolic inhibitors or enhancers.
Psychosocial factors may affect response, and comorbid personality or substance abuse disorders are especially likely to complicate anxiety disorders. When initial treatment fails, the physician has to decide when to change the treatment plan. There have been few systematic trials of treatment-refractory patients with anxiety disorders. If after treatment at what is considered an adequate dose for 4 to 6 weeks a patient shows no response, the medication should be changed.
If partial response is seen after this period, there is still a chance that the patient will respond after another 4 to 6 weeks of therapy with increased dosages.
For some antidepressants, the studies on a potential dose-response relationship are inconclusive, perhaps due to the lack of statistical power for showing a difference between lower and higher doses. According to clinical experience, however, a trial with a higher dose in patients with insufficient response is warranted. Elderly patients may take longer to show a response. Table III contains options in case of drug inefficacy or intolerance. In patients who are unresponsive to psychotropic drugs, the addition of CBT is generally recommended.
When all standard treatments have failed, the off-label use of drugs may be considered, for example, drugs licensed for another anxiety disorder or that are not licensed but have shown efficacy in clinical studies. Such drugs include quetiapine and agomelatine. Therefore, only a few studies for the treatment of GAD have been performed with older patients.
Controlled studies have shown the efficacy of duloxetine, venlafaxine, pregabalin, and quetiapine in patients over 65 years old. In the elderly, effect sizes for CBT tend to be somewhat smaller than those found in mixed-age populations.
There are some randomized, placebo-controlled studies of pharmacotherapy for anxiety disorders in children and adolescents showing efficacy of sertraline, fluoxetine, and duloxetine in young patients with GAD, of venlafaxine and paroxetine in SAD, and of sertraline, fluvoxamine, and fluoxetine in mixed samples, including patients with separation anxiety disorder, GAD, and SAD.
There is also a paucity of treatment studies for children with selective mutism. Small studies have shown that psychotherapeutic approaches were at least better than waitlist controls.
A large study suggested no substantial increase in the risk of cardiac malformations attributable to antidepressant use during the first trimester. In such cases, CBT should be considered as an alternative to medication treatment. Psychotherapy All patients with anxiety disorders require supportive talks and attention to the emotional problems that are associated with the anxiety disorder.
Psychoeducation includes information about the physiology of the bodily symptoms of anxiety reactions and the rationale of available treatment possibilities. Outcomes We used the following scales to measure outcomes, all of which had already been validated in Japanese.
The STAI is a commonly used measure of state and trait anxiety [ 31 ]. The details of each scale are as follows. K-6 The K6 scale was designed to be sensitive to the threshold for the clinically significant range of the distribution of nonspecific distress in an effort to maximize its ability to discriminate cases of serious mental illness from non-cases [ 32 ].
The scale contains 20 items that ask how often over the past week the patients experienced symptoms associated with depression. It provides a simple descriptive profile and a single index value for health status. The five facets are observing, describing, acting with awareness, the non-judging of inner experience, and non-reactivity to inner experience.
