Hepatic fibrosis - renal cysts - mental retardation is a rare form of intellectual disability mainly characterized by below-average mental ability, accumulation of liver scar tissue, and cysts in the kidneys. Large amounts of liver scar tissues suggests that many liver cells are dying and that the liver is inflammed. This can lead to the liver functioning properly and not be able to perform important tasks for the body, such as regulating the blood, digesting nutrients, producing fat molecules and breaking down toxic molecules. Additionally, cysts in the kidney can lead to loss of kidney function. Individuals may have problems with urination and eliminating toxic substances out of the body. Intellectual disability may cause individuals to have problems with reasoning and solving problems, as well as performing day-to-day tasks. The disorder is often diagnosed early in childhood, since the symptoms are very apparent. Slow mastering of basic tasks, and having difficulty remembering things may also suggest this disorder in children. Treatment is developed on a case-by-case basis and depends on the specific needs of the patient. Doctors may suggest patients undergo surgery to remove kidney cysts, although this is usually not necessary. In more severe cases, patients may have to undergo dialysis for blood cleansing purposes. Doctors may also encourage patients to live a healthier lifestyle, avoiding alcohol and tylenol, to help with the healing of the liver. Doctors seek help from various therapists and community services to provide support and care for families affected by intellectual disability.
