ABSTRACT

Objective:To investigate the development of vestibular system function in 7 to 14 years old normal boys and the ADHD boys;Methods:The present study involved two groups of subjects:148 ADHD boys(age range 7 years to 14 years) diagnosed with DSM-IV diagnostic criteria and 148 normal boys with the same age.Each group was divided into 4 clusters according to two years gap.All subjects were tested for the vestibular system function by the Vestibular Function Test System 2000/ ENG-V600 with the eye movement index.Results:From 7 to 14 years,the development of vestibular system function in normal boys had the characters as the description below.The optokinetic system function exhibited more development from seven years in the normal group.From 7 to 10 years,the time delay of saccade and anti-saccade in normal boys was significantly shorter(In the normal controls,the delay time of left saccade was 149?66 ms in 7-8 years old boys,108?64 ms in 9-10 years old boys,117?72 ms in 9-10 years old boys,the delay time of left anti-saccade was 178?127ms in 7-8 years old boys,101?88 ms in 9-10 years old boys,P
