Your response to the fear Anxiety disorders are serious medical illnesses that affect approximately 19 million American adults. These disorders fill people's lives with overwhelming anxiety and fear. Unlike the relatively mild, brief anxiety caused by a stressful event such as a business presentation or a first date, anxiety disorders are chronic, relentless, and can grow progressively worse if not treated. Both fear and anxiety send signals through the body that prepare all systems for possible danger. Hormones, such as adrenaline and catecholamine, are released in what is known as the "fight or flight" response. The sudden increase in hormone levels speeds up the heart and increases the amount of blood being pumped. At the same time, the muscles tighten, increasing the individual's ability to fight or flee from danger. The intensity of these physiological responses varies according to the seriousness of the event or thought that sparked the emotion, the strength of the individual's fear or anxiety, and his or her previous experience and genetic makeup. While both fear and anxiety can provoke an arousal response, their other effects diverge. Very intense fear sometimes serves to "freeze" the body to protect it from harm, causing little or no change in heart rate and blocking the impulse to move. In anxiety, the physical changes caused by arousal lead to a second stage marked by thought patterns such as worry, dread, and mental replays of anxiety-arousing events.
Learn worries Unrestrained anxiety can lead to any of several emotional disorders, all characterized by an unpleasant and overwhelming mental tension with no apparent identifiable cause. While most people with anxiety disorders are completely aware that their thoughts and behavior are irrational and inappropriate, this insight gives them no help in controlling their symptoms. Anxiety disorders are surprisingly frequent, and affect more Americans than does any other emotional disorder. They are more common than depression, manic depression, or abuse of alcohol and other substances. According to the American Psychiatric Association, while depressive disorders affect one person in 20, one in 12 suffers an anxiety disorder. Because consumers and doctors alike are less attuned to anxiety disorders than other emotional problems, these disorders often go unrecognized. This is unfortunate, because most cases of anxiety can be treated successfully. In fact, anxiety disorders are considered the most treatable of all emotional problems.
Learn symptoms of depression The hallmark of this problem is chronic worry and tension with no apparent cause. People suffering from generalized anxiety disorders may worry excessively about health, money, family, or work, often anticipating disaster. Although they are usually aware that their anxiety is more intense than necessary, they can't seem to let it go. Constant worrying contributes to trouble sleeping and relaxing. People with anxiety disorders may startle easily and have trouble concentrating. Generalized anxiety disorder often leads to depression. Physical symptoms of this disorder include: trembling, twitching, muscle tension, headaches, irritability, sweating, nausea, hot flashes, light-headedness, and difficulty breathing. GAD is diagnosed when psychological and physical symptoms of anxiety last more than a month and are not accompanied by the symptoms of other anxiety disorders. Symptoms of this disorder are often mild, and do not interfere with work or social situations. If symptoms are severe, however, they can disrupt daily activities. Because people with generalized anxiety disorder often have another physical or emotional disorder, such as depression, there has been much learned debate as to whether anxiety disorder exists on its own. But recent studies indicate that there really is such a disorder, and that it can be helped by diagnosis and treatment. The symptoms of generalized anxiety disorder usually begin in youth and may go untreated for decades. However, they tend to diminish with age. One study found that only 3 percent of cases of generalized anxiety disorder began in those 65 and over. The problem is more common among women than men and often runs in families.
The anxiety associated with diets? Diet also can be a culprit. The most common dietary offenders are caffeine and caffeine-like substances found in coffee, tea, and many soft drinks. In sensitive individuals, the jitteriness precipitated by caffeine can reach panic levels. In rare cases, extreme vitamin deficiencies may also lead to anxiety. The anxiety associated with taking or discontinuing medications and other substances can usually be easily relieved once the cause is recognized. It's therefore essential to provide your doctor with a complete run-down of your medicines--including over-the-counter products and of your eating and drinking habits.
Scientists research depression Using brain imaging technologies and neurochemical techniques, scientists are finding that a network of interacting structures is responsible for these emotions. Much research centers on the amygdala, an almond-shaped structure deep within the brain. The amygdala is believed to serve as a communications hub between the parts of the brain that process incoming sensory signals and the parts that interpret them. It can signal that a threat is present, and trigger a fear response or anxiety. It appears that emotional memories stored in the central part of the amygdala may play a role in disorders involving very distinct fears, like phobias, while different parts may be involved in other forms of anxiety. Other research focuses on the hippocampus, another brain structure that is responsible for processing threatening or traumatic stimuli. The hippocampus plays a key role in the brain by helping to encode information into memories. Studies have shown that the hippocampus appears to be smaller in people who have undergone severe stress because of child abuse or military combat. This reduced size could help explain why individuals with PTSD have flashbacks, deficits in explicit memory, and fragmented memory for details of the traumatic event. By learning more about brain circuitry involved in fear and anxiety, scientists may be able to devise new and more specific treatments for anxiety disorders. For example, it someday may be possible to increase the influence of the thinking parts of the brain on the amygdala, thus placing the fear and anxiety response under conscious control. In addition, with new findings about neurogenesis (birth of new brain cells) throughout life, perhaps a method will be found to stimulate growth of new neurons in the hippocampus in people with post-traumatic stress disorder.
Effective treatments anxiety disorders Before treatment can begin, the doctor must conduct a careful diagnostic evaluation to determine whether your symptoms are due to an anxiety disorder, which anxiety disorder(s) you may have, and what coexisting conditions may be present. Anxiety disorders are not all treated the same, and it is important to determine the specific problem before embarking on a course of treatment. Sometimes alcoholism or some other coexisting condition will have such an impact that it is necessary to treat it at the same time or before treating the anxiety disorder. When you undergo treatment for an anxiety disorder, you and your doctor or therapist will be working together as a team. Together, you will attempt to find the approach that is best for you. If one treatment doesn't work, the odds are good that another one will. And new treatments are continually being developed through research. So don't give up hope.
Drugs for psychiatric disorders Psychiatrists or other physicians can prescribe medications for anxiety disorders. These doctors often work closely with psychologists, social workers, or counselors who provide psychotherapy. Although medications won't cure an anxiety disorder, they can keep the symptoms under control and enable you to lead a normal, fulfilling life. Medication is most helpful when there is clear disorder or, sometimes, a specific target symptom for a particular drug. Usually, a pattern of symptoms point to a specific chemical imbalance. Whenever an imbalance appears evident through a person's disordered behavior and emotional state, medication centers on modifying the strength of the signal or readjusting the balance among them.
Professional help you If you, or someone you know, has symptoms of anxiety, a visit to the family physician is usually the best place to start. A physician can help determine whether the symptoms are due to an anxiety disorder, some other medical condition, or both. Frequently, the next step in getting treatment for an anxiety disorder is referral to a mental health professional. Remember, though, that when you find a health care professional that you're satisfied with, the two of you are working together as a team. Together you will be able to develop a plan to treat your anxiety disorder that may involve medications, cognitive-behavioral or other talk therapy, or both, as appropriate.
