When people are confronted with unpleasant and potentially harmful stimuli such as foul odors or tastes, PET-scans show increased bloodflow in the amygdala. In these studies, the participants also reported moderate anxiety. This might indicate that anxiety is a protective mechanism designed to prevent the organism from engaging in potentially harmful behaviors.
Psychodynamic theory posits that anxiety is often the result of opposing unconscious wishes or fears that manifest via maladaptive defense mechanisms (such as suppression, repression, anticipation, regression, somatization, passive aggression, dissociation) that develop to adapt to problems with early objects (e.g., caregivers) and empathic failures in childhood. For example, persistent parental discouragement of anger may result in repression/suppression of angry feelings which manifests as gastrointestinal distress (somatization) when provoked by another while the anger remains unconscious and outside the individual's awareness. Such conflicts can be targets for successful treatment with psychodynamic therapy. While psychodynamic therapy tends to explore the underlying roots of anxiety, cognitive behavioral therapy has also been shown to be a successful treatment for anxiety by altering irrational thoughts and unwanted behaviors.
Anxiety disorders can often be addressed successfully with a combination of therapy and medication. For therapy, patients may undergo psychotherapy or cognitive behavioral therapy, in which they learn to change how they respond to situations that induce anxiety. For medications, clinicians may, for limited periods of time, prescribe antidepressants such as selective serotonin reuptake inhibitors or tricyclics, tranquilizers such as benzodiazepines; they may also prescribe beta blockers for specific events. Different strategies can also help people who experience feelings of anxiety but the severity of which falls below the clinical threshold for diagnosis. Habits such as exercising, sleeping well, and limiting the amount of caffeine and alcohol consumed can prove helpful. Strategies such as taking deep breaths, acknowledging limits to fully controlling situations, pushing back against anxious or irrational thoughts, and observing the circumstances that tend to produce anxiety are proven to reduce anxiety by helping people feel better prepared in the future.
It's important to note that everyone feels anxiety to some degree regularly throughout their life - fear and anxiety are adaptive and helpful emotions that can function to help us notice danger or threat, keep us safe, and help us adapt to the environment. Anxiety disorders represent states when fear or anxiety becomes severe or extreme, to the extent that it causes an individual significant distress, or impairs their ability to function in important facets of life such as work, school, or relationships. It is also important that risk factors don't at all imply that anxiety is anyone's fault; anxiety disorders are a very common difficulty that people experience. In this section, we will review risk factors for anxiety disorders. There are many potential risk factors for anxiety disorders, and most people likely experience multiple different combinations of risk factors, such as neurobiological factors, genetic markers, environmental factors, and life experiences. However, we do not yet fully understand what causes some people to have anxiety disorders.
Although phobias can be crippling, they're not obvious at all times. In fact, they may not surface until you confront a specific situation and discover you're incapable of overcoming your fear. "A person who's afraid of snakes can go for years without having a problem," Winston says. "But then suddenly their kid wants to go camping, and they realize they need treatment."
The emotional effects of anxiety may include "feelings of apprehension or dread, trouble concentrating, feeling tense or jumpy, anticipating the worst, irritability, restlessness, watching (and waiting) for signs (and occurrences) of danger, and, feeling like your mind's gone blank" as well as "nightmares/bad dreams, obsessions about sensations, déjà vu, a trapped-in-your-mind feeling, and feeling like everything is scary."
Some research suggests that people who have panic disorder might be very sensitive to sensory experiences (such as sunlight, smells and changes in the weather), but there's not enough evidence yet to say for sure. Also it's not clear whether having a high level of sensitivity to these sorts of things is something that might cause you to develop panic disorder, or whether it may be an effect of having it.
Physical Symptoms: People with panic disorder may also have irritable bowel syndrome, characterized by intermittent bouts of gastrointestinal cramps and diarrhea or constipation, or a relatively minor heart problem called mitral valve prolapse, which can trigger panic attacks in some people. In fact, panic disorder often coexists with unexplained medical problems, such as chest pain not associated with a heart attack or chronic fatigue.
An anxiety or panic attack often comes on suddenly, with symptoms peaking within 10 minutes. For doctors to diagnose a panic attack, they look for at least four of the following signs: sweating, trembling, shortness of breath, a choking sensation, chest pain, nausea, dizziness, fear of losing your mind, fear of dying, feeling hot or cold, numbness or tingling, a racing heart (heart palpitations), and feeling unusually detached from yourself.
If your child is experiencing separation anxiety, be supportive and caring when they are in distress but try to avoid changing behavior to overly accommodate the anxiety. If you notice the separation anxiety lasting for longer than four weeks, seek professional help from a psychologist or counselor in order to learn effective behavioral techniques to treat the anxiety.
Panic attacks are common among all anxiety disorders but what sets panic disorder apart is that panic attacks are unexpected and occur "out of the blue" without an obvious trigger (American Psychiatric Association, 2013; Craske & Barlow, 2007). These unexpected panic attacks must be associated with a significant change in behavior or be followed by at least one month of persistent worry about having another attack or about what will happen if you have another panic attack.
Anxiety disorders are treated through medication and therapy. You might feel embarrassed talking about the things you are feeling and thinking, but talking about it, say experts, is the best treatment. A particular form of therapy is considered most effective: cognitive behavioral therapy, or CBT for short. Antidepressants — the types of medication most frequently used to treat depression — are the drugs that also work best for anxiety disorders.
Until recently, panic disorder was not distinguished from agoraphobia (distressing anxiety resulting from being outside the home, travelling via public transit, being in open or claustrophobic environments, or being in crowds that generally leads to extreme avoidance due to fear of not being able to escape in those situations; APA, 2013). As it stands in the current Diagnostic and Statistical Manual of Mental Disorders - 5 agoraphobia is one of the most common disorders to co-occur with panic disorder. Current estimates contend that just under 2% of teens and adults have agoraphobia (Kessler et al., 2012). Often, people associate panic attacks or their panic disorder with certain places, people, or events and the fear of another attack occurring can lead to comorbid fears of the location or idea that there is no escape, which leads to extreme avoidance. Panic disorder can also occur simultaneously with other anxiety disorders, such as Generalized Anxiety Disorder (GAD) and/or Social Anxiety Disorder (SAD), for example.
Those who experience panic attacks are often nervous about having additional episodes. To avoid having a panic attack in a public space, they may avoid places like shopping malls or other crowded spots where previous incidents may have occurred or places that they fear will not allow them immediate access to help, such as an airplane or movie theater. This avoidance when severe may lead to agoraphobia, the inability to leave familiar, safe surroundings because of intense fear and anxiety about having a panic attack outside the home.
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 attacks, also called panic attacks, are episodes of intense fear and emotional distress that usually occur suddenly and without warning, and typically last from several minutes up to an hour. These attacks may have a discrete trigger, but they also can occur without any identifiable cause. Anxiety attacks are often recurrent, and are very distressing to the people who experience them, as well as their loved ones.
Most treatment providers for anxiety-related disorders can be found in hospitals, clinics, private or group practices. Some also operate in schools (licensed mental health counselors, clinical social workers, or psychiatric nurses ). There is also the growing field of telehealth in which mental health workers provide their services through an internet video service, streaming media, video conferencing or wireless communication. Telehealth is particularly useful for patients that live in remote rural locations that are far from institutions that provide mental health services. Mental health providers that work in telehealth can only provide services to patients currently located in the state in which the provider is licensed.
