graphic rating scale

a series of anchored points (usually from low to high) on a continuum, often used to evaluate the performance or behavior of individuals in a work or learning environment. For example, a graphic rating scale for assessing an employee’s overall performance during the past year might take the form of a line with the response options of 1 (poor), 2 (below average), 3 (average), 4 (above average), and 5 (excellent) listed. The supervisor would mark the line to indicate the employee’s performance level.

metachromatic leukodystrophy

metachromatic leukodystrophy

an autosomal recessive disorder (see recessive allele) characterized by deficiency or absence of the enzyme arylsulfatase A, which results in loss of myelin in the nervous system and accumulation of cerebroside sulfate (a type of myelin lipid) within the white matter of the central nervous system. Loss of motor function and deterioration in mental ability most commonly develop after the 1st year of life (late infantile form), but symptoms may also appear between 3 and 10 years of age (juvenile form) or around age 30 (adult form).
