MRIMagnetic Resonance Imaging EI Early Intervention ICT Information and Communications Technology CT CareToyNeurodevelopmental disorders affect motor, cognitive, language, learning, and behavioural development with lifelong consequences. Early identification of infants at risk for neurodevelopmental disorders is a major prerequisite for intervention programmes. This ensures that interventions which aim to positively modify the natural history of these disorders can start in the first weeks or months of life. As indicated by recent scientific evidence, gene abnormalities or congenital brain lesions are not the sole determinants for the neurodevelopmental outcome of affected infants. In fact, environment and experience may modify brain development and improve the outcome in infants at risk for neurodevelopmental disorders. In this review, we analyse the complexity and sensitivity of the brain to environmental stimuli, highlighting clinical effects of early intervention, mainly reported so far in preterm infants, and summarizing the effects of enriched environment on human and animal models. Finally, we discuss some new approaches to early intervention, based on recent neurophysiological theories and new breakthroughs in biotechnologies for diagnosis and rehabilitation.In the last decades several studies have explored and demonstrated the effects of environment and experience on brain development and plasticity. This review aims to (1) highlight some underlying neuronal and biological mechanisms of environmental enrichment both in animal and human models; (2) summarize the effects of early intervention in infants at risk for neurodevelopmental disorders and report their most representative results; and (3) explore the new breakthroughs of early intervention in the field of novel recent neurophysiological theories, and application of information and communication technologies. NEURODEVELOPMENTAL DISORDERS: THE IMPORTANCE OF EARLY IDENTIFICATION AND INTERVENTIONNeurodevelopmental disorders are impairments of brain growth and development affecting several brain functions, and include cognitive, motor, language, learning, and behavioural disorders due to many causes -genetic, lesional, and environmental. 1 Infants at high risk for neurodevelopmental disorders can be identified early, i.e. in the first weeks or months of life, through careful clinical evaluation (i.e. developmental tests, neurological examination, observation of spontaneous movement patterns) combined with specific technical tools such as neuroimaging (cranial ultrasounds, brain magnetic resonance imaging [MRI]), neurophysiological tests (e.g. electroencephalography, evoked potentials), and genetic tests (karyotype, comparative genomic hybridization-microarray). The application of evidence-based recommendations or decision-making processes, which combine the use of clinical and technical tools at a proper point during development, is crucial for early detection of infants at risk for neurodevelopmental disorders by clinicians.An example of early identif...

CareToy system is an innovative tele-rehabilitative tool, useful in providing intensive, individualized, home-based, family-centred Early Intervention (EI) in infants. Our aim was to evaluate, through a Randomized Clinical Trial (RCT) study, the effects of CareToy intervention on early motor and visual development in preterm infants. 41 preterm infants (range age: 3.0–5.9 months of corrected age) were enrolled and randomized into two groups, CareToy and Standard Care. 19 infants randomized in CareToy group performed a 4-week CareToy program, while 22 allocated to control group completed 4 weeks of Standard Care. Infant Motor Profile (IMP) was primary outcome measure, Alberta Infant Motor Scale (AIMS) and Teller Acuity Cards were secondary ones. Assessments were carried out at baseline (T0) and at the end of CareToy training or Standard Care period (T1). T1 was the primary endpoint. After RCT phase, 17 infants from control group carried out a 4-week CareToy program, while 18 infants from the CareToy group continued with Standard Care. At the end of this phase, infants were re-assessed at T2. In RCT phase, delta IMP total score and variation and performance sub-domains were significantly higher (P<0.050) in CareToy group if compared to Standard Care group. Similar results were found for Teller Acuity Cards, while no differences between groups were found for AIMS. No differences were found in any outcome measure results (T2-T0), between infants who started CareToy training before or after one month of standard care. This RCT study confirms the results of a previous pilot study, indicating that CareToy system can provide effective home-based EI.Trial Registration: This trial has been registered at www.clinicaltrials.gov (Identifier NCT01990183).

Noninvasive rehabilitation strategies for children with unilateral cerebral palsy are routinely used to improve hand motor function, activity, and participation. Nevertheless, the studies exploring their effects on brain structure and function are very scarce. Recently, structural neuroplasticity was demonstrated in adult poststroke patients, in response to neurorehabilitation. Our purpose is to review current evidence on the effects of noninvasive intervention strategies on brain structure or function, in children with unilateral cerebral palsy. The main literature databases were searched up to October 2013. We included studies where the effects of upper limb training were evaluated at neurofunctional and/or neurostructural levels. Only seven studies met our selection criteria; selected studies were case series, six using the intervention of the constraint-induced movement therapy (CIMT) and one used virtual reality therapy (VR). CIMT and VR seem to produce measurable neuroplastic changes in sensorimotor cortex associated with enhancement of motor skills in the affected limb. However, the level of evidence is limited, due to methodological weaknesses and small sample sizes of available studies. Well-designed and larger experimental studies, in particular RCTs, are needed to strengthen the generalizability of the findings and to better understand the mechanism of intervention-related brain plasticity in children with brain injury.
