E. Raymond-speden et al., Intellectual, neuropsychological, and academic functioning in long-term survivors of leukemia, J PED PSYCH, 25(2), 2000, pp. 59-68
Objective: To assess the effects of treatment for acute lymphoblastic leuke
mia (ALL) on children's cognitive functioning.
Method: Participants were long-term survivors of ALL treated with cranial i
rradiation and central nervous system (CNS) chemotherapy (n = 20), or CNS c
hemotherapy only (n = 21), healthy children (n = 21), and children with chr
onic asthma (n = 21). The groups were compared on measures of intellectual,
neuropsychological, and academic functioning.
Results: CNS chemotherapy, with and without cranial irradiation, was associ
ated with significantly lower levels of intellectual and academic functioni
ng. Children with chronic asthma obtained lower scores than healthy control
s, but these differences were not significant. Tests of neuropsychological
functioning did not consistently separate the groups.
Conclusions: CNS chemotherapy and, to a lesser extent, chronic: illness bot
h contribute to the poorer performance of long-term survivors of ALL on mea
sures of intellectual and academic functioning.
