Fear and anxiety in our life

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.

As long as there's a good reason for fear or anxiety, and it doesn't interfere with the ability to work, play, and socialize, it is not considered a problem. But when anxiety takes on a life of its own and begins to disrupt everyday activities, the situation is no longer normal. A genuine emotional disorder is now at work... and it's time to see a doctor.

Effective treatments for anxiety disorders are available, and research is yielding new, improved therapies that can help most people with anxiety disorders lead productive, fulfilling lives. If you think you have an anxiety disorder, you should seek information and treatment.

Symptoms of anxiety disorders

Although anxiety disorders take several distinct forms, certain general symptoms tend to appear in all of them. When discussing their condition, people with anxiety disorders often report the following: - cold/clammy hands - diarrhea - dizziness - dry mouth - fast pulse - fatigue - jitteriness - lump in the throat - muscle aches - numbness/tingling of hands, feet, or other body part - racing or pounding heart - rapid breathing - shakiness - sweating - tension - trembling - upset stomach

Feelings associated with anxiety include impatience, apprehensiveness, irritability, and decreased ability to concentrate. People suffering from anxiety may also worry, for no particular reason, that something bad is going to happen to themselves or their loved ones. Individuals with anxiety disorders may make such statements as: - I always thought I was just a worrier, but I would worry about things for days, to the point where I couldn't even sleep. - I had a very strong feeling of impending doom, like I was losing control in an extreme way. - I was always worried that if I didn't do certain things, my parents were going to die. - I felt as if my heart was going to explode, and I couldn't calm down.

Not everyone who is depressed has all depression's symptoms, but everyone who is depressed has at least some of them, co-existing, on most days. Depression can range in intensity from mild to severe. Depression can co-occur with other medical disorders such as cancer, heart disease, stroke, Parkinson's disease, Alzheimer's disease, and diabetes. In such cases, the depression is often overlooked and is not treated. If the depression is recognized and treated, a person's quality of life can be greatly improved.

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.

Causes of worries

Biochemical theory suggests that biologic imbalances, perhaps among the neurotransmitters in the brain, may be the primary cause of anxiety disorders. Indeed, in one study researchers were able to trigger a panic attack in some people simply by infusing certain chemicals. Many scientists involved in anxiety research now argue that correcting biochemical imbalances with medication should be the first goal of treatment. Other studies suggest that biochemical changes can also be achieved through the psychological and behavioral changes produced by psychotherapy.

Learning theory views anxiety as a learned behavior that can be unlearned. This theory posits that a person's anxiety can be reduced by persistently confronting the feared situation or object. And some people do, in fact, change their thinking and experience significant relief without any medication.

An imbalance in these neurotransmitters can cause a corresponding shift in our thoughts. But is the reverse also true? Can a determined change in our thinking alter the chemistry in the brain? Many experts are convinced this is true; and behavioral therapy aimed at changing our reactions does, in fact, cure many problems. Indeed, for some disorders, such as phobias, this type of therapy remains the most effective alternative.

1. Remember that though your feelings and symptoms are very frightening, they are not dangerous or harmful. 2. Understand that what you are experiencing is an exaggeration of your normal bodily reactions to stress. 3. Do not fight your feelings or try to wish them away. The more you are willing to face them, the less intense they will become. 4. Do not add to your panic by thinking about what "might" happen. 5. Stay in the present. Notice what is really happening to you as opposed to what you think might happen. 6. Label your fear level from zero to 10 and watch it go up and down. Notice that it does not stay at a very high level for more than a few seconds. 7. When the fear begins to trigger "what if" thinking, focus on and carry out a simple and manageable task such as counting backwards from 100 by threes or snapping a rubber band on your wrist. 8. Notice that when you stop adding frightening thoughts to your fear, it begins to fade. 9. When the fear comes, expect and accept it. Wait and give it time to pass without running away from it. 10. Be proud of the progress you make, and think about how good you will feel when you succeed this time.

Our eating maybe root of anxiety

Although it's uncommon, certain medical problems can mimic the symptoms of anxiety, or even produce it. The palpitations and shortness of breath caused by an irregular heartbeat can easily be mistaken for anxiety. A clot in the lung (pulmonary embolism) often causes unexplained feelings of anxiety. Neurological problems such as epilepsy and brain disorders can be responsible for symptoms of anxiety. So can anemia, diabetes, thyroid disease, and adrenal problems. In general, these symptoms will disappear when the underlying disease is brought under control, although the anxiety sometimes requires separate treatment.

Alcohol is a well-known yet consistently underdiagnosed cause of anxiety. Both excessive consumption of alcohol and withdrawal from it can lead to anxiety. The problem often goes unrecognized because people may minimize or omit their alcohol intake when talking with the doctor, and doctors may neglect to ask. Interestingly, alcohol does not appear to increase the risk of anxiety disorders in later life.

Scientists research worries

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.

Also, research indicates that other brain parts called the basal ganglia and striatum are involved in obsessive-compulsive disorder.

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.

Scientists are also conducting clinical trials to find the most effective ways of treating anxiety disorders. For example, one trial is examining how well medication and behavioral therapies work together and separately in the treatment of obsessive-compulsive disorder. Another trial is assessing the safety and efficacy of medication treatments for anxiety disorders in children and adolescents with co-occurring attention deficit hyperactivity disorder. For more information about clinical trials, for example the National Library of Medicine's clinical trials database.

Treatment of fears

If you have been treated previously for an anxiety disorder, be prepared to tell the doctor what treatment you tried. If it was a medication, what was the dosage, was it gradually increased, and how long did you take it? If you had psychotherapy, what kind was it, and how often did you attend sessions? It often happens that people believe they have "failed" at treatment, or that the treatment has failed them, when in fact it was never given an adequate trial.

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.
