Overview

Body dysmorphic disorder (BDD) is a mental disorder that involves a disturbed body image. It is generally diagnosed in those who are extremely critical of their physique or self-image, despite the fact there may be no noticeable disfigurement or defect.

Most people wish they could change or improve some aspect of their physical appearance, but people suffering from BDD, generally considered of normal 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 at their appearance. They tend to be very secretive and reluctant to seek help because they are afraid others will think them vanity|vain or they may feel too embarrassed to do so.

Ironically, BDD is often misunderstood as a vanity driven obsession, whereas it is quite the opposite; people with BDD believe themselves to be irrevocably ugly or defective.

BDD combines obsessive and compulsive aspects, which links it to the OCD spectrum disorders among psychologists. People with BDD may engage in compulsive mirror checking behaviors or mirror avoidance, typically think about their appearance for more than one hour a day, and in severe cases may drop all social contact and responsibilities as they become homebound. The disorder is linked to an unusually high suicide rate among all mental disorders.

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 due to the value of oneself being so closely linked with their perceived appearance. The prevalence of BDD is equal in men and women, and causes chronic social anxiety for those suffering from the disorder[4].

Phillips & Menard (2006) found the completed suicide rate in patients with BDD to be 45 times higher than in the general US population. This rate is more than double that of those with Clinical depression and three times as high as those with bipolar disorder[1]. There has also been a suggested link between undiagnosed BDD and a higher than average suicide rate among people who have undergone cosmetic surgery[2].

Historical Perspective

BDD was first documented in 1886 by the researcher Morselli, who called the condition simply "Dysmorphophobia". BDD was first recorded/formally recognized in 1997 as a disorder in the DSM; however, in 1987 it was first truly recognized by the American Psychiatric Association.

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.

Classification

Pathophysiology

BDD usually develops in adolescence, a time when people are generally most sensitive about their appearance. However, many patients suffer for years before seeking help. When they do seek help through mental health professionals, patients often complain of other symptoms such as depression, social anxiety or obsessive compulsive disorder, but do not reveal their real concern over body image. Most patients cannot be convinced that they have a distorted view of their body image, due to the very limited knowledge of the disorder as compared to OCD or others.

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, including:

A chemical imbalance in the brain. An insufficient level of serotonin, one of the brain's neurotransmitters involved in mood and pain, may contribute to body dysmorphic disorder. Although such an imbalance in the brain is unexplained, it may be hereditary.

Obsessive-compulsive disorder. BDD often occurs with OCD, where the patient uncontrollably practices ritual behaviors that may literally take over their life. A history of, or genetic predisposition to, OCD may make people more susceptible to BDD.

Generalized anxiety disorder. Body dysmorphic disorder may co-exist with generalized anxiety disorder. This condition involves excessive worrying that disrupts the patient's daily life, often causing exaggerated or unrealistic anxiety about life circumstances, such as a perceived flaw or defect in appearance, as in BDD.

Epidemiology and Demographics

According to Dr Katharine Phillips (2004) :

Although large epidemiologic surveys of BDD's prevalence have not been done, studies to date indicate that BDD is relatively common in both nonclinical and clinical settings (Phillips & Castle, 2002). Studies in community samples have reported current rates of 0.7% and 1.1%, and studies in nonclinical student samples have reported rates of 2.2%, 4%, and 13% (Phillips & Castle, 2002). A study in a general inpatient setting found that 13% of patients had BDD (Grant, Won Kim, Crow, 2001). Studies in outpatient settings have reported rates of 8%-37% in patients with OCD, 11%-13% in social phobia, 26% in trichotillomania, 8% in major depression, and 14%-42% in atypical major depression (Phillips & Castle, 2002). In one study of atypical depression, BDD was more than twice as common as OCD (Phillips, Nierenberg, Brendel et al 1996), and in another (Perugi, Akiskal, Lattanzi et al, 1998) it was more common than many other disorders, including OCD, social phobia, simple phobia, generalized anxiety disorder, bulimia nervosa, and substance abuse or dependence. In a dermatology setting, 12% of patients screened positive for BDD, and in cosmetic surgery settings, rates of 6%-15% have been reported (Phillips & Castle, 2002).

BDD is underdiagnosed, however. Two studies of inpatients (Phillips, McElroy, Keck et al, 1993, and Grant, Won Kim, Crow, 2001), as well as studies in general outpatients (Zimmerman & Mattia, 1998) and depressed outpatients (Phillips, Nierenberg, Brendel et al 1996), systematically assessed a series of patients for the presence of BDD and then determined whether clinicians had made the diagnosis in the clinical record. All four studies found that BDD was missed by the clinician in every case in which it was present. Thus, underdiagnosis of BDD appears common.

Diagnosis

Symptoms

  • Compulsive mirror checking, glancing in reflective doors, windows and other reflective surfaces.
  • Alternatively, an inability to look at one's own reflection or photographs of oneself; often the removal of mirrors from the home.
  • Compulsive skin-touching, especially to measure or feel the perceived defect.
  • Reassurance-seeking from loved ones.
  • Social withdrawal and co-morbid depression.
  • Obsessive viewing of favorite celebrities or models the person suffering from BDD may wish to resemble.
  • Excessive grooming behaviors: combing hair, plucking eyebrows, shaving, etc.
  • Obsession with plastic surgery or multiple plastic surgeries with little satisfactory results for the patient.
  • In obscure cases patients have performed plastic surgery on themselves, including liposuction and various implants with disastrous results.
