A comparison of memory and attention in Turner syndrome and learning disability.

Compared short-term verbal memory, sustained attention, and impulsivity in 13 children with Turner syndrome to 13 females and 14 males with learning disability who had neuropsychological patterns similar to the children with Turner syndrome. Similar patterns of short-term memory deficits were found in all three groups. There were no significant differences among the groups on computer measures of sustained attention and impulsivity. However, extreme variability of the attention and impulsivity scores for the Turner syndrome group may reflect atypical attention deficit disorder in some of these children.
