Body dysmorphic disorder (BDD) (previously known as Dysmorphophobia and sometimes referred to as Body dysmorphia) is a psychiatric disorder in which the affected person is excessively concerned about and preoccupied by an imagined or minor defect in his or her physical features. The sufferer may complain of several specific features or a single feature, or a vague feature or general appearance, causing psychological distress that impairs occupational and/or social functioning, sometimes to the point of complete social isolation.[1] It is estimated that between 1%-2% of the world's population meet all the diagnostic criteria for BDD. Individuals with very obvious and immediately-noticeable defects should not be diagnosed with BDD, however culture and clinician bias may play a significant part in the subjectivity behind determining what physical appearance is considered 'normal' and in whom the disorder is diagnosed.[2] BDD combines obsessive and compulsive aspects, linking it, among psychologists, to the obsessive-compulsive spectrum disorders. The exact cause or causes of BDD is unknown, but most clinicians believe it to be a complex combination of biological, psychological and environmental factors. Onset of symptoms generally occurs in adolescence or early adulthood, although cases of BDD onset in children and older adults is not unknown. BDD is often misunderstood to affect mostly women, however research shows that it affects men and women equally. The disorder is linked to significantly diminished quality of life and co-morbid major depressive disorder and social phobia. With a completed-suicide rate more than double than that of major depression, and a suicidal ideation rate of around 80%, BDD is considered a major risk factor for suicide. A person with the disorder may be treated with psychotherapy, medication, or both. Research has shown cognitive behavioural therapy (CBT) and selective serotonin reuptake inhibitors (SSRIs) to be effective in treating BDD. BDD is a chronic illness and symptoms are likely to persist, or worsen, if left untreated.
OverviewThe Diagnostic and Statistical Manual of Mental Disorders defines body dysmorphic disorder as a preoccupation with an imagined or minor defect in appearance which causes clinically significant distress or impairment in social, occupational, or other important areas of functioning. The individual's symptoms mustn't be better accounted for by another disorder, for example weight concern is usually more accurately attributed to an eating disorder. The disorder generally is diagnosed in those who are extremely critical of their physique or self-image even though there may be no noticeable disfigurement or defect, or a minor defect which is not recognised by most people. Most people wish that they could change or improve some aspect of their physical appearance; but people suffering from BDD, generally of normal or even highly attractive appearance, believe that they are so unspeakably hideous that they are unable to interact with others or function normally for fear of ridicule and humiliation about their appearance. They tend to be very secretive and reluctant to seek help because they fear that others will think them vain or because they feel too embarrassed. It has also been suggested that fewer men seek help for the disorder than women.[3] Ironically, BDD is often misunderstood as a vanity-driven obsession, whereas it is quite the opposite, for people with BDD believe themselves to be irrevocably ugly or defective. BDD combines obsessive and compulsive aspects, linking it, among psychologists, to the Obsessive-Compulsive spectrum disorders. People with BDD may compulsively look at themselves in the mirror or avoid mirrors, typically think about their appearance for at least one hour a day (and usually more), and in severe cases may drop all social contact and responsibilities as they become a recluse. A German study has shown that 1–2% of the population meet all the diagnostic criteria of BDD, with a larger percentage showing milder symptoms of the disorder (Psychological Medicine, vol 36, p 877). Chronically low self-esteem is characteristic of those with BDD, because the one's assessment of one's value is so closely linked with one's perception of one's appearance. BDD is diagnosed equally in men and women, and causes chronic social anxiety for its sufferers.[1] Phillips & Menard (2006) found the completed-suicide rate in patients with BDD was 45 times higher than in the general United States population. This rate is more than double that of those with clinical depression and three times as high as that of those with bipolar disorder.[4] Suicidal ideation is also found in around 80% of people with BDD.[5] There has also been a suggested link between undiagnosed BDD and a higher than average suicide rate among people who have undergone cosmetic surgery.[6] HistoryIn 1886, BDD was first documented by the researcher Morselli, who called the condition simply "Dysmorphophobia". BDD was first truly recognized by the American Psychiatric Association in 1987, and in 1997, BDD was first recorded and formally recognized as a disorder in the DSM. In his practice, Freud eventually had a patient who would today be diagnosed with the disorder; Russian aristocrat Sergei Pankejeff, nicknamed "The Wolf Man" by Freud himself in order to protect Pankejeff's identity, had a preoccupation with his nose to an extent that greatly limited his functioning. DiagnosesAccording to the DSM IV, to be diagnosed with BDD, a person must possess the following criteria:
In most cases, BDD is under-diagnosed. In a study of 17 patients with BDD, BDD was noted in only five patient charts, and none of the patients received an official diagnosis of BDD despite the fact that it was present.[8] BDD is often under-diagnosed because the disorder was only recently included in DSM IV, therefore clinician knowledge of the disorder, particularly among general practitioners, is not widespread.[9] Also, BDD is often associated with shame and secrecy, therefore patients often fail to reveal their appearance concerns for fear of appearing vain or superficial.[9] BDD is also often misdiagnosed because its symptoms can mimic that of another psychiatric disorder, such as major depressive disorder or social phobia.[10] and the root of the individual's problems remain unresolved. Many individuals with BDD also possess a poor level of insight and regard their problem as one of a physical nature rather than psychiatric, therefore individuals may seek cosmetic treatment rather than mental health treatment. PrevalenceStudies show that BDD is common in not only nonclinical settings, but clinical settings, as well. A study was done of 200 people with DSM-IV Body Dysmorphic Disorder. These people were of age 12 or older and were available to be interviewed in person. They were obtained from mental health professionals, advertisements, the subject's friends and relatives, and non-psychiatrist physicians. Fifty-three subjects were receiving medication, 33 were receiving psychotherapy, and 48 were receiving both medication and psychotherapy. The severity of BDD was assessed using the Yale-Brown Obsessive Compulsive Scale modified for BDD, and symptoms were assessed using the Body Dysmorphic Disorder Examination. Both tests were designed specifically to assess BDD. Results showed that BDD occurs in 0.7% - 1.1% of community samples and 2%-13% of nonclinical samples. 13% of psychiatric inpatients had BDD.[11] Studies also found that some of the patients initially diagnosed with OCD had BDD, as well. 53 patients with OCD and 53 patients with BDD were compared in a study. Clinical features, comorbidity, family history, and demographic features were compared between the two groups. Nine of the 62 subjects (14.5%) of those with OCD also had BDD.[12] ComorbidityThere is a high degree of comorbidity with other psychiatric disorders, often resulting in misdiagnoses by clinicians. Research suggests that around 76% of people with BDD will experience major depressive disorder at some point in their life,[13] significantly higher than the 10%-20% expected in the general population. Around 37% of people with BDD will also experience social phobia[13] and around 32% experience obsessive-compulsive disorder.[13] The most common personality disorders found in individuals with BDD are avoidant personality disorder and dependant personality disorder which conforms to the introverted, shy and neurotic traits usually found in individuals with the disorder. Eating disorders, such as Anorexia nervosa and Bulimia nervosa, are also sometimes found in people with BDD, usually women, as are Trichotillomania and sub-type disorders Olfactory Reference Syndrome and muscle dysmorphia.[13] A similar disorder, gender-identity disorder, in which the patient is upset with his or her entire sexual biology, often precipitates BDD-like feelings being directed specifically at external sexually dimorphic features, which are in constant conflict with the patient's internal psychiatric gender. The high rate of comorbidity of BDD in GID patients results in an estimated suicide-attempt rate of 20%; the suicide-attempt rate for patients with only BDD is 15%.[14][15] Common symptoms and behaviorsThere are many common symptoms and behaviors associated with BDD. Often these symptoms and behaviours are determined by the nature of the BDD sufferer's perceived defect, for example, use of cosmetics is most common in those with a perceived skin defect, therefore many BDD sufferers will only display a few common symptoms and behaviors. SymptomsCommon symptoms of BDD include:
Compulsive behaviorsCommon compulsive behaviors associated with BDD include:

DevelopmentBDD usually develops in adolescence, a time when people are generally most sensitive about their appearance. However, many patients suffer for years before seeking help. An absolute cause of body dysmorphic disorder is unknown. However research shows that a number of factors may be involved and that they can occur in combination. Some of the theories regarding BDD's cause are summarized below: Biological/genetic
Psychological
Environmental
PersonalityCertain personality traits may make someone more susceptable to developing BDD. Personality traits which have been proposed as contributing factors include; [22]
Since personality traits among people with BDD vary greatly, it is unlikely that these are the direct cause of BDD. However, like psychological and environmental factors, they may act as triggers in individuals who already have a genetic predisposition to developing the disorder.[22] The Disabling Effects of BDDBDD can be anywhere from slightly to severely debilitating. It can make normal employment or family life impossible. Those who are in regular employment or who have family responsibilities would almost certainly find life more productive and satisfying if they did not have the symptoms. The partners and family of sufferers of BDD may also become involved and suffer greatly, sometimes losing their loved one to suicide. Studies have shown a positive correlation between BDD symptoms and poor quality of life. Quality of life for inidividuals with BDD has also been shown to be poorer than those found in major depressive disorder, dysthymia, obsessive-compulsive disorder, social phobia, panic disorder, premenstrual dysphoric disorder and Post traumatic stress disorder.[23] Because BDD onset typically occurs in adolescence, an individual's academic performance may be significantly impacted. Depending on the severity of symptoms, an individual may experience great difficulty maintaining grades and attendance or, in severe cases, an individual may drop out of school and therefore not reach the academic level they are capable of. The vast majority of people with BBD (90%) say that their disorder impacts on their academic/occupational functioning,[5] while 99% say that their disorder impacts on their social functioning.[5] Sufferers of BDD may often find themselves getting almost 'stuck' in moping around. That is to say that sufferers, with such a type of depression, can in some cases appear to take a long time to get everything done. However, this is not actually the case, as it is simply that the BDD sufferers will often just sit or lie down for prolonged periods of time, without being able to actually motivate themselves until it becomes completely necessary to get back up. This can often cause little to get done by sufferers, and they can have little self motivation with anything, including relationships with other people. However, contrary to this, when the action is relevant to the person's image, it is more common for the sufferer to exhibit a fanatic and extreme approach, applying their attention fully to self-grooming/modification. PrognosisMany individuals with BDD have repeatedly sought treatment from dermatologists or cosmetic surgeons with little satisfaction before finally accepting psychiatric or psychological help. Treatment can improve the outcome of the illness for most people. Other patients may function reasonably well for a time and then relapse, while others may remain chronically ill. Research on outcome without therapy is not known but it is thought the symptoms persist unless treated. TreatmentsStudies have found that the psychodynamic approach to therapy, traditional talk therapy, has not been proven effective in treating BDD. However, Cognitive Behavior Therapy (CBT) has proven more effective. In a study of 54 patients with BDD who were randomly assigned to Cognitive Behavior Therapy or no treatment, BDD symptoms decreased significantly in those patients undergoing CBT. BDD was eliminated in 82% of cases at post treatment and 77% at follow-up. (8) Due to low levels of serotonin in the brain, another commonly used treatment is SSRI drugs (Selective Serotonin Reuptake Inhibitor). 74 subjects were enrolled in a placebo-controlled study group to evaluate the efficiency of Fluoxetine hydrochloride (Prozac), a SSRI drug. Patients were randomized to receive 12-weeks of double-blind treatment with fluoxetine or the placebo. At the end of 12 weeks, 53% of patients responded to the fluoxetine.[24] Body Dysmorphic Disorder is a chronic disorder that if left untreated can worsen with time. Without treatment, BDD could last a lifetime. In many cases, as illustrated in The Broken Mirror by Katharine Phillips, the social and professional lives of many patients disintegrates because they are so preoccupied with their appearance.[25] See also
