title: Is there any difference between high-risk infants with different birth weight and gestational age in neurodevelopmental characters?
abstract: OBJECTIVE
  This study is aimed to investigate differences between cognitive, language and motor development of high-risk infants related to birth weight and gestational age.
  
  
  METHODS
  One hundred sixty high-risk infants who were born 32 weeks, 1 500 gr and below included in this study. According to corrected age, 58 infants were 1 month, 72 were at 4 months, 82 were at 8 months and 65 were 12 months old. Infants were seperated two groups according to gestational age <30 weeks and 30-32 weeks and birth weight ≤1 000 gr and 1 001-1 500 gr. Infants motor development were assessed with Bayley-III Infant and Toddler Development Motor Scale (Bayley-III) and Neuro Sensory Motor Developmental Scale (NSMDA), cognitif and lanuage development were Bayley-III cognitive and Language scales. Assessments were applied by the same physiotherapist at 1 month, 4 months, 8 months and 12 months old infants in corrected age. Mann-Whitney U Test, 2 x 2 Chi-Square test ve Fisher's exact tests were used to compare group data. Statistical significance was determined p<0.05.
  
  
  RESULTS
  Cognitive, motor and language developments were in normal ranges in all infants. There were no statistical differences in cognitive, language and motor development between groups (p>0.05).
  
  
  CONCLUSIONS
  Results of this study showed that the motor, cognitive and language development were normal in all high risk infants and power gestational age and birth weight did not affect these parametes.
