Anxiety, on the other hand, is more general and complex. It is felt in anticipation of danger, and is associated with the ability to predict, prepare for, and adapt to change. Often, it lasts a long time, and its cause remains ill-defined. For example, someone uneasy about public speaking may experience a tightness in the stomach for days before a scheduled talk. 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. Thousands of scientific studies over the past several years show that high blood pressure, ulcers, migraine headaches, strokes, alcoholism, depression, anger, fatigue, drug addiction and many other medical conditions are often due to the long-term effects of stress.
Among the professionals who can help are psychiatrists, psychologists, social workers, and counselors. However, it's best to look for a professional who has specialized training in cognitive-behavioral therapy and/or behavioral therapy, as appropriate, and who is open to the use of medications, should they be needed. You may be concerned about paying for treatment for an anxiety disorder. If you belong to a Health Maintenance Organization or have some other kind of health insurance, the costs of your treatment may be fully or partially covered. There are also public mental health centers that charge people according to how much they are able to pay. If you are on public assistance, you may be able to get care through your state Medicaid plan.
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. Prescription drugs and those purchased over the counter also can cause anxiety symptoms. Cold medicines, diet pills, antispasmodic medications, stimulants, digitalis, thyroid supplements, and, paradoxically, antidepressants given to reduce panic all may cause anxiety. Discontinuing a variety of drugs, including tranquilizers, sleeping pills, and certain blood-pressure medicines can lead to withdrawal symptoms that often include anxiety.
Most people with depression can get help from treatment. For most people, spotting depression early and getting it treated might cut down on how long and how serious the depression is. The most common treatments are antidepressant medicines, "talk" therapy, or a combination of both. You and your doctor can work together to decide on the right depression treatment for you. Studies show that antidepressants have been effective in treating depression. A type of medicine called selective serotonin reuptake inhibitors (SSRIs) is most often prescribed by doctors. In "talk" therapy, the patient and therapist talk about the patient's experiences, relationships, events, and feelings. Two of the approaches found to be effective for treating depression are interpersonal therapy and cognitive- behavioral therapy.
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.
Many organizations today supports research into the causes, diagnosis, prevention, and treatment of anxiety disorders and other mental illnesses. Studies examine the genetic and environmental risks for major anxiety disorders, their course--both alone and when they occur along with other diseases such as depression--and their treatment. The ultimate goal is to be able to cure, and perhaps even to prevent, anxiety disorders. Like heart disease and diabetes, the brain disorders are complex and probably result from a combination of genetic, behavioral, developmental, and other factors. 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.
It is not entirely clear why psychotropic medications work; yet, it appears that they reestablish balance within the chemistry of the brain. Behavior is determined through messages transmitted within the brain from one nerve cell to another through various chemicals. These chemicals are called neurotransmitters. Through the millions of nerve cells within the brain, chemicals trigger memories, sleep patterns, perceptions, feelings, moods and thoughts. The electric current that carries the messages are received by nerve ends, called synapses, which then release the neurotransmitter. These chemicals, in turn, propagate the message by stimulating the next nerves in line to send on the electrical message. Once used, the neurotransmitter chemical is returned and stored in the nerve end. This recycling process is called reuptake. When this signaling process goes askew, the effects are seen in a person's behavior and experienced in his emotions, perceptions, sensations, and ideas. 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.
