Glossary for Anxiety

  • 22q11.2 deletion syndrome: A rare genetic disorder caused by the absence of a small portion of genetic material. A small section of chromosome 22 is missing at a location called q11.2. Chromosome 22 is one of 23 pairs of chromosomes that exist in humans.
  • 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.

  • ADHD: Attention Deficit Hyperactivity Disorder (ADHD) is a mental and behavioral disorder characterized by behavioral problems such as hyperactivity, inattention, concentration difficulty, and other mental symptoms. Typically, ADHD and associated hyperactivity is known as a childhood disorder, although ADD/ADHD in adults is known to be under-diagnosed. It is distinguished from Attention Deficit Disorder (ADD) which has a reduced focus on hyperactivity type symptoms.
