Glossary for Aggression

Medical terms related to Aggression or mentioned in this section include:

  • 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.

  • Acid-Base Imbalance: A disruption to the normal acid-base equilibrium in the body. There are four main groups of disorder involving an acid-base imbalance: respiratory acidosis or alkalosis and metabolic acidosis or alkalosis. Obviously the severity of symptoms is determined by the degree of imbalance.
  • Acute intermittent porphyria: A rare inherited metabolic disorder caused by a disturbed porphyrin metabolism resulting in increased production of porphyrin or its precursors.

Normally the phenylalanine is converted into tyrosine. The severity of the symptoms can range from severe enough to cause mental retardation to mild enough not to require treatment. Severity is determined by the level of impairment of enzyme activity of phenylalanine hydroxylase.
