Mental retardation - microcephaly - unusual facies refers to a form of intellectual disability that is characterized mainly by below-average mental ability, a small head, and unusual facial features. Thus, individuals with this form of intellectual disability often have problems with face movements. Like other people 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 an unusually small head and abnormal facial features 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. Physicians may suggest undergoing surgery to fix abnormal facial features. Doctors seek help from various therapists and community services to provide support and care for families affected by intellectual disability.
