Our aim was to examine intellectual development in children with congenital
hemiplegia from early childhood to adolescence. METHOD: Full-scale IQ (FIQ),
Verbal IQ (VIQ), and Performance IQ (PIQ) scores were measured in 32 participants
(19 males, 13 females) with congenital hemiplegia at mean ages of 4 years 6
months (SD 7mo; 31 participants), 7 years (SD 6mo; 23 participants), and 14 years
(SD 1y 5mo; 26 participants). RESULTS: The FIQ and VIQ scores did not change with
age, but the PIQ declined significantly (0.7 points per year; p=0.004). The
estimated mean (95% confidence intervals) scores in males born at term with
right-sided lesions without epilepsy were FIQ 106.5 (95.29-117.74), VIQ 105.9
(95.57-116.24), and PIQ 103.7 (93.19-114.31). Those means were negatively
associated with preterm birth. PIQ was negatively associated with epilepsy. VIQ
increased more quickly in males and in children with right-sided lesions.
INTERPRETATION: The results confirm previous findings of FIQ stability, PIQ
decline, the impact of epilepsy, and the status of females with left-sided
lesions, and also reveal the effect of gestational age at birth. They underline
the importance of management focused on nonverbal functions and further the
debate about the early lateralization of language, the 'crowding effect', and the
difference in brain plasticity between males and females.
