Conclusion : Positive clinical ly meaningful effects ( > 5 points ) are seen to an age of 36 months , but are no longer present at 5 years
Objective : To determine in a systematic review , whether interventions for infant development that involve parents , improve neurodevelopment at 12 months corrected age or older .
Early experience alters brain function and structure.
OBJECTIVE To investigate the effects of early experience on brain function and structure . METHODS A r and omized clinical trial tested the neurodevelopmental effectiveness of the Newborn Individualized Developmental Care and Assessment Program ( NIDCAP ) .  Thirty preterm infants , 28 to 33 weeks ' gestational age ( GA ) at birth and free of known developmental risk factors , participated in the trial . NIDCAP was initiated within 72 hours of intensive care unit admission and continued to the age of 2 weeks , corrected for prematurity . Control ( 14 ) and experimental ( 16 ) infants were assessed at 2 weeks ' and 9 months ' corrected age on health status , growth , and neurobehavior , and at 2 weeks ' corrected age additionally on electroencephalogram spectral coherence , magnetic resonance diffusion tensor imaging , and measurements of transverse relaxation time . RESULTS The groups were medically and demographically comparable before as well as after the treatment . However , the experimental group showed significantly better neurobehavioral functioning , increased coherence between frontal and a broad spectrum of mainly occipital brain regions , and higher relative anisotropy in left internal capsule , with a trend for right internal capsule and frontal white matter . Transverse relaxation time showed no difference . Behavioral function was improved also at 9 months ' corrected age . The relationship among the 3 neurodevelopmental domains was significant . The results indicated consistently better function and more mature fiber structure for experimental infants compared with their controls . CONCLUSIONS This is the first in vivo evidence of enhanced brain function and structure due to the NIDCAP . The study demonstrates that quality of experience before term may influence brain development significantly
