Body dysmorphic disorder (BDD), occasionally still called dysmorphophobia, is a mental disorder characterized by the obsessive idea that some aspect of ones own body part or appearance is severely flawed and therefore warrants exceptional measures to hide or fix it. In BDDs delusional variant, the flaw is imagined. If the flaw is actual, its importance is severely exaggerated. Either way, thoughts about it are pervasive and intrusive, and may occupy several hours a day, causing severe distress and impairing ones otherwise normal activities. BDD is classified as a somatoform disorder, and the DSM-5 categorizes BDD in the obsessive–compulsive spectrum, and distinguishes it from anorexia nervosa. BDD is estimated to affect from 0.7% to 2.4% of the population. It usually starts during adolescence and affects both men and women. The BDD subtype muscle dysmorphia, perceiving the body as too small, affects mostly males. Besides thinking about it, one repetitively checks and compares the perceived flaw, and can adopt unusual routines to avoid social contact that exposes it. Fearing the stigma of vanity, one usually hides the preoccupation. Commonly unsuspected even by psychiatrists, BDD has been underdiagnosed. Severely impairing quality of life via educational and occupational dysfunction and social isolation, BDD has high rates of suicidal thoughts and attempts at suicide. History
In 1886, Enrico Morselli reported a disorder that he termed dysmorphophobia, which described the disorder as a feeling of being ugly even though there does not appear to be anything wrong with the persons appearance.
Craniometaphyseal dysplasia is a rare skeletal disorder that results from a mutation in the ANKH or GJA1 genes. The condition is characterized abnormal facial features, impairment of cranial nerves, and malformation of the long bones in the limbs. Signs and symptoms
Signs and symptoms include:
syndromic facies
hearing loss
facial paralysis

Genetics
The autosomal dominant form is caused by a mutation in ANKH on chromosome 5 (5p15.2-p14.1). The autosomal recessive form is caused by a mutation in a mutation in GJA1 on chromosome 6 (6q21-q22). The recessive form tends to be more severe than the dominant form. Diagnosis
Craniometaphyseal dysplasia is diagnosed based on clinical and radiographic findings that include hyperostosis. Some things such as cranial base sclerosis and nasal sinuses obstruction can be seen during the beginning of the childs life. In radiographic findings the most common thing that will be found is the narrowing of foramen magnum and the widening of long bones. Once spotted treatment is soon suggested to prevent further compression of the foramen magnum and disabling conditions. Treatment
The only treatment for this disorder is surgery to reduce the compression of cranial nerves and spinal cord. However, bone regrowth is common since the surgical procedure can be technically difficult. Genetic counseling is offered to the families of the people with this disorder. References
