Glossary for Balance symptoms

Medical terms related to Balance symptoms or mentioned in this section include:

  • 47,XXX syndrome: A genetic condition where females have an extra X chromosome in each of their cells. Normally female cells have two X chromosomes. This is not usually an inherited condition but a defect that occurs during cell division. Often the condition is asymptomatic.
  • ADD: Attention Deficit Disorder (ADD) is a mental and behavioral disorder characterized by behavioral problems such as hyperactivity, inattention, concentration difficulty, and other mental symptoms. The related description Attention Deficit Hyperactivity Disorder (ADHD) may be a more modern description of the disease.

    Misdiagnosis of ADD is a well-known controversy in the sense that cases of hyperactivity in children may be over-diagnosed. There is a tendency for parents to seek and doctors to prescribe the drug Ritalin even in cases where the diagnosis of ADD or ADHD may be incorrect. Alternative diagnoses include normal child behavior (i.e. just an active child), food intolerances, or other behavioral disorders (see misdiagnosis of ADD).

    On the other hand, ADD is under-diagnosed in adults, with a large number of adults having ADD without knowing it; see misdiagnosis of Adult ADD.

  • Abdominal Aneurysm: Dilatation of a section of the abdominal aorta, usually due to a weakness in the wall of the artery

Some forms of sideroblastic anemia are inherited but most tend to be acquired due to such things as exposure to toxins and certain drugs, leukemia, inflammatory conditions such as rheumatoid arthritis and nutritional deficiencies (e.g. copper and pyridoxine deficiency).
