Anxiety Disorder
Department of Psychiatry
at Far Eastern Memorial Hospital 2008.6
|
Anxiety is a normal reaction to stress. It helps one deal with a perceived threat, either external or internal (e.g. studying for an exam, preparing for a speech, etc.). In general, it helps one cope, but when anxiety becomes an excessive, irrational dread of everyday situations, it has become a disabling disorder. Unlike the relatively mild, brief anxiety caused by a stressful event (such as a first date), anxiety disorders last at least 6 months and can get worse if they are not treated. Anxiety disorders commonly occur along with other mental or physical illnesses, including alcohol or substance abuse, which may mask anxiety symptoms or make them worse. In some cases, these other illnesses need to be treated before a person will respond to treatment for the anxiety disorder.
There are five major types of anxiety disorders, namely:
generalized anxiety disorder, obsessive-compulsive disorder, panic disorder, post-traumatic stress disorder and social phobia (or social anxiety disorder). Each anxiety disorder has different symptoms, but all the symptoms cluster around excessive, irrational fear and dread.
Effective therapies for anxiety disorder is available. In general, anxiety disorders are treated with medication, specific types of psychotherapy, or both. Treatment choices depend on the problem and the person’s preference. Before treatment begins, a doctor must conduct a careful diagnostic evaluation to determine whether a person’s symptoms are caused by an anxiety disorder or a physical problem. If an anxiety disorder is diagnosed, the type of disorder or the combination of disorders that are present must be identified, as well as any coexisting conditions, such as depression or substance abuse. Sometimes alcoholism, depression, or other coexisting conditions have such a strong effect on the individual that treating the anxiety disorder must wait until the coexisting conditions are brought under control.
People with anxiety disorders who have already received treatment should tell their current doctor about that treatment in detail. If they received medication, they should tell their doctor what medication was used, what the dosage was at the beginning of treatment, whether the dosage was increased or decreased while they were under treatment, what side effects occurred, and whether the treatment helped them become less anxious. If they received psychotherapy, they should describe the type of therapy, how often they attended sessions, and whether the therapy was useful.
Often people believe that they have “failed” at treatment or that the treatment didn’t work for them when, in fact, it was not given for an adequate length of time or was administered incorrectly. Sometimes people must try several different treatments or combinations of treatment before they find the one that works for them.
Treatment options include medications, psychotherapy or both.
The principal medications used for anxiety disorders are antidepressants, anti-anxiety drugs, and beta-blockers to control some of the physical symptoms. With proper treatment, many people with anxiety disorders can lead normal, fulfilling lives.

Generalized Anxiety Disorder (GAD)
Department of Psychiatry
at Far Eastern Memorial Hospital 2005.6 |
GAD is diagnosed when a person worries excessively about a variety of everyday problems, even though there is little or nothing to provoke it, with at least 6 months duration. They anticipate disaster and are overly concerned about health issues, money, family problems, or difficulties at work. People with GAD can’t seem to get rid of their concerns, even though they usually realize that their anxiety is more intense than the situation warrants. They can’t relax, startle easily, have difficulty concentrating, trouble falling asleep or staying asleep. Physical symptoms that often accompany the anxiety include fatigue, headaches, muscle tension, muscle aches, difficulty swallowing, trembling, twitching, irritability, sweating, nausea, lightheadedness, having to go to the bathroom frequently, feeling out of breath, and hot flashes. When their anxiety level is mild, people with GAD can function socially and hold down a job. When anxiety level gets severe, carrying out even the simplest daily activities is a challenge.
The disorder comes on gradually and can begin across the life cycle, though the risk is highest between childhood and middle age. There is evidence that genes play a modest role in GAD.
Other anxiety disorders, depression, or substance abuse often accompany GAD, which rarely occurs alone. GAD is commonly treated with medication or cognitive-behavioral therapy, but co-occurring conditions must also be treated using the appropriate therapies.

Obsessive-Compulsive Disorder (OCD)
Department of Psychiatry
at Far Eastern Memorial Hospital 2005.6 |
People with obsessive-compulsive disorder (OCD) have persistent, upsetting thoughts (obsessions) and use rituals (compulsions) to control the anxiety these thoughts produce. Most of the time, the rituals end up controlling them. Performing such rituals is not pleasurable. At best, it produces only temporary relief from the anxiety created by obsessive thoughts.
Examples of obsessions and compulsions include fear of dirt or germs which results in repeated washing of hands, fear of intruder which results in locking and relocking doors, need to repeatedly check things, touching things (especially in a particular sequence) or counting things, having frequent thoughts of violence and harming loved ones, persistently thinking about performing sexual acts the person dislikes, difficulty in throwing things out (so they accumulate) or hoard unneeded items, or having thoughts that are prohibited by religious beliefs. People with OCD may also be preoccupied with order and symmetry.
Healthy people also have rituals, such as checking to see if the stove is off several times before leaving the house. The difference is that people with OCD perform their rituals even though they find the repetition distressing and in doing so, interferes with daily life. Although most adults with OCD recognize that what they are doing is senseless, some adults and most children may not realize that their behavior is out of the ordinary.
OCD can be accompanied by eating disorders, other anxiety disorders or depression. It strikes men and women in roughly equal numbers and usually appears in childhood, adolescence, or early adulthood. One-third of adults with OCD develop symptoms as children, and research indicates that OCD might run in families.
The course of the disease is quite varied. Symptoms may come and go, ease over time, or get worse. If OCD becomes severe, it can keep a person from working or carrying out normal responsibilities at home. People with OCD may try to help themselves by avoiding situations that trigger their obsessions, or they may use alcohol or drugs to calm themselves.
OCD usually responds well to treatment with certain medications and/or exposure-based psychotherapy, in which people face situations that cause fear or anxiety and become less sensitive (desensitized) to them.

Panic Disorder
Department of Psychiatry
at Far Eastern Memorial Hospital 2005.6 |
This is characterized by sudden attacks of terror, usually accompanied by a pounding heart, sweatiness, weakness, faintness, or dizziness, hands may tingle or feel numb, with nausea, chest pain, or smothering sensations. Panic attacks usually is accompanied by a fear of impending doom, or a fear of losing control. A fear of one’s own unexplained physical symptoms is also a symptom of panic disorder. People having panic attacks sometimes believe they are having heart attacks, losing their minds, or on the verge of death. Panic attacks are often unpredictable and many worry intensely and dread the next attack (anticipatory anxiety). Panic attacks can occur at any time, even during sleep. An attack usually peaks within 10 minutes, but some symptoms may last much longer.
Panic disorder affects women twice as as men. Panic attacks often begin in late adolescence or early adulthood, but not everyone who experiences panic attacks will develop panic disorder. Many people have just one attack and never have another. The tendency to develop panic attacks appears to be inherited.
People who have full-blown, repeated panic attacks can become very disabled by their condition and should seek treatment before they start to avoid places or situations where panic attacks have occurred. For example, if a panic attack happened in an elevator, someone with panic disorder may develop a fear of elevators that could affect the choice of a job or an apartment, and restrict where that person can seek medical attention or enjoy entertainment. Some people’s lives become so restricted that they avoid normal activities, such as grocery shopping or driving. About one-third become housebound or are able to confront a feared situation only when accompanied by a spouse or other trusted person. When the condition progresses this far, it is called agoraphobia, or fear of open spaces.
Early treatment can often prevent agoraphobia, but people with panic disorder may sometimes go from doctor to doctor for years and visit the emergency room repeatedly before someone correctly diagnoses their condition. This is unfortunate, because panic disorder is one of the most treatable of all the anxiety disorders, responding in most cases to certain kinds of medication or certain kinds of cognitive psychotherapy, which help change thinking patterns that lead to fear and anxiety.
Panic disorder is often accompanied by other serious problems, such as depression, drug abuse, or alcoholism. These conditions need to be treated separately. Symptoms of depression include feelings of sadness or hopelessness, changes in appetite or sleep patterns, low energy, and difficulty concentrating. Most people with depression can be effectively treated with antidepressant medications, certain types of psychotherapy, or a combination of the two.

Post-Traumatic Stress Disorder (PTSD)
Department of Psychiatry
at Far Eastern Memorial Hospital 2005.6 |
Post-traumatic stress disorder (PTSD) develops after a terrifying ordeal that involved physical harm or the threat of physical harm. The person who develops PTSD may have been the one who was harmed, the harm may have happened to a loved one, or the person may have witnessed a harmful event that happened to loved ones or strangers.
PTSD was first brought to public attention in relation to war veterans, but it can result from a variety of traumatic incidents, such as mugging, rape, torture, being kidnapped or held captive, child abuse, car accidents, train wrecks, plane crashes, bombings, or natural disasters such as floods or earthquakes.
Common signs and symptoms of PTSD are: startle easily, become emotionally numb (especially in relation to people with whom they used to be close), lose interest in things they used to enjoy, have trouble feeling affectionate, be irritable, become more aggressive, or even become violent, avoid situations that remind them of the original incident. PTSD symptoms seem to be worse if the event that triggered them was deliberately initiated by another person, as in a mugging or a kidnapping. Most people with PTSD repeatedly relive the trauma in their thoughts during the day and in nightmares when they sleep. These are called flashbacks. Flashbacks may consist of images, sounds, smells, or feelings, and are often triggered by ordinary occurrences, such as a door slamming or a car backfiring on the street. A person having a flashback may lose touch with reality and believe that the traumatic incident is happening all over again.
Not every traumatized person develops full-blown or even minor PTSD. Symptoms usually begin within 3 months of the incident but occasionally emerge years afterward. They must last more than a month to be considered PTSD. The course of the illness varies. Some people recover within 6 months, while others have symptoms that last much longer. In some people, the condition becomes chronic.
PTSD can occur at any age, including childhood. Women are more likely to develop PTSD than men, and there is some evidence that susceptibility to the disorder may run in families. PTSD is often accompanied by depression, substance abuse, or one or more of the other anxiety disorders.
Treatment of PTSD usually involves a combination of psychotherapy and medication (antidepressants, anti-anxiety, beta-blocker, etc).

Social Phobia (Social Anxiety Disorder, SAD))
Department of Psychiatry
at Far Eastern Memorial Hospital 2005.6 |
Social phobia, also called social anxiety disorder, is diagnosed when people become overwhelmingly anxious and excessively self-conscious in everyday social situations. People with social phobia have an intense, persistent, and chronic fear of being watched and judged by others and of doing things that will embarrass them. They can worry for days or weeks before a dreaded situation. This fear may become so severe that it interferes with work, school, and other ordinary activities, and can make it hard to make and keep friends. Although they realize that their fears about being with people are excessive or unreasonable, they are unable to overcome them.
Social phobia can be limited to one situation (such as talking to people, eating or drinking, or writing on a blackboard in front of others) or may be so broad (such as in generalized social phobia) that the person experiences anxiety around almost anyone other than the family.
Physical symptoms that often accompany social phobia are blushing, profuse sweating, trembling, nausea, and difficulty talking. When these symptoms occur, people with PTSD feel as though all eyes are focused on them.
Women and men are equally likely to develop the disorder, which usually begins in childhood or early adolescence. There is some evidence that genetic factors are involved. Social phobia is often accompanied by other anxiety disorders or depression, and substance abuse may develop if people try to self-medicate their anxiety.
Social phobia can be successfully treated with psychotherapy, medications or both.
