Mental retardation - X-linked - Brunner type refers to a form of intellectual disability that is characterized mainly by below-average mental ability, and a variety of behavioral problems. Hence, individuals with this form of intellectual disability may have problems controlling their emotions. 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 behavioral problems 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. Psychiatrists may suggest patients to undergo psychotherapy sessions or take anti-psychotic medications to help limit behavioral problems. Doctors seek help from various therapists and community services to provide support and care for families affected by intellectual disability.
