Mental retardation - X-linked dysmorphism refers to a form of intellectual disability that is characterized mainly by below-average mental ability, and partially dislocated knees and teeth as well as facial abonormalities. Hence, individuals with this form of intellectual disability may have problems with breathing and eating and with tasks involving physical activity. Males are more likely than females to have this condition. Like other individuals with intellectual disability, an individual with this condition often has problems with reasoning and solving problems, as well as performing day-to-day tasks. The condition is often diagnosed during childhood. Doctors diagnose this form of intellectual disability if partially dislocated knees and teeth are observed. Signs like walking and talking late, slow mastering of basic tasks, and having difficulty remembering things may also suggest this condition in children. Treatment is developed on a case-by-case basis and depends on the specific needs of the patient. Bone specialists may suggest patients undergo surgery to fix knee and teeth problems. Doctors seek help from various therapists and community services to provide support and care for families affected by intellectual disability.
