RESUMO
ObjectiveTo study the intelligence quotient(IQ) profile of the children with idiopathic generalized tonic-clonic seizure (GTCS) and the factors influencing IQ of them.MethodsAll 28 children with GTCS were selected who were aged 9 ～ 16 years in 20 GTCS families in a mountain area of the south of Anhui Province,all available healthy siblings of the children included in the epilepsy group,did not have epilepsy,and were nearest in age to the children with GTCS ( control group 1 ),and thirty children aged 9 ～ 16 years old who had lived in the same village ( control group 2) entered into our study.The IQ was studied of the three groups of children and the factors influencing IQ of children with GTCS at the same time.The data were input SPSS12.0 and analyzed.ResultsThe IQ of children with GTCS(85.64 ±20.57)was lower than that control group 1( 103.39 ± 11.17)and the control group 2 ( 106.17 ± 11.67).The difference between children with GTCS and the two control groups were significant for almost all the subtest quotients except completion of drawing and picture arrangement.No significant differences were found between the control group 1 and the control group 2 on the IQ and the subtest quotients.IQ scores of children with GTCS showed significant linear correlation with father's education( r=0.453,P＜0.01 ),age at onset of epilepsy( r=0.506,P＜0.01 ),duration of seizure disorder( r=-0.533,P＜0.0l ),status epilepticus( r=-0.732,P＜0.01),total number of seizures( r=-0.761,P＜0.01) and seizure frequency ( r=-0.708,P ＜ 0.01 ).ConclusionThe IQ scores of the children with idiopathic GTCS are lower significantly than general children population.Epilepsy-related variables affecting IQ scores of the children with idiopathic GTCS are duration of seizure disorder,status epilepticus,age at onset of epilepsy,total number of seizures,seizure frequency.
RESUMO
Objective To investigate the intelligence standard for diagnose the sub-cretin children and children with mental retardation of socio-cultural type.Methods The full intelligence quotient(IQ),verbal intelligence quotient(VIQ)and performance intelligence quotient(PIQ)was tested by Wechsler scale(C-WISC)for mild iodine deficiency disordem children,children living in abnormal socio-cultural condition and normal children aged 7～14 years old in Qinba mountain area.The test results had been compared between the groups.Results There were no significant difference between psychomotor functioning well children and children living normal sociocuhural condition in VIQ,PIQ and full IQ(89.24±18.44 vs 90.75±17.58,87.58±15.78 vs 88.95±15.56,87.42±17.84 vs 89.02±17.18,t=1.14,1.19 and 1.24,respectively,all P＞O.05).PIQ and full IQ were significantly lower in mild iodine deficiency disorders children than in children with abnormal socio-cultural background (65.81±10.22 vs 72.33±13.23,62.42±12.31 vs 68.13±14.54,t=3.26,2.55,P＜0.01 or＜0.05,respectively).But the VIQ was not significantly different between these two groups.The average difference of VIQ and PIQ among mild iodine deficiency disorders children wag-0.32 without significant difierence(t=0.28,P＞0.05),however it was-2.91 among children under abnormal socio-cultural condition with significant difierenee(t=-3.59,P＜0.01).Conclusions IQ for iodine deficiency disorders children is characterized by that VIQ is damaged in parallel with PIQ,while that in children under abnormal soeio-cuhural condition is marked by that VIQ is retarded more severely than PIQ,which ean be used as an intelligence standard for differentiating the sub-cretin children from children wjth socio-cuhural mental retardation.
