Twenty-one children (approximate ages 6 to 16), drawn from the larger pool of 100, with Tourette's Syndrome were evaluated to: (1) determine the prevalence of learning disorder in this population; (2) identify particular areas of academic difficulty; and (3) consider the spectrum of central nervous system processing deficits in these children. Not one subject achieved at or above expectancy in all seven of the academic tests given, and only four had a discrepancy in only one area. The greatest number of failures were in spelling (71 percent) and writing (62 percent). Approximately half had difficulty with calculation, about 28 percent had difficulty in word identification, and 24 percent in reading comprehension. Problems in written expression were correlated with visual-motor difficulty. (Contains 20 references.) (DB)
