The prenatal period and the early years of life have an extraordinary importance on the physical and psychological well-being not only in the infancy, but throughout the life cycle. There is strong empirical evidence that early life is highly vulnerable to the negative effects of adverse experiences or toxic stress as maternal prenatal anxiety or child maltreatment. Research in the field of developmental neurobiology provides important keys about the mechanisms across these experiences affect the process of child development provoking alterations and dysfunctions in brain architecture. Such alterations tend to be persistent and increase the risk of physical, cognitive, social and emotional problems along infancy, adolescence and adulthood. The evidences clearly support the need and social relevancy of implementing early intervention preventive programs for children and families who are at risk for experiencing toxic stress. Such policies and programs should begin as early as possible in order to reduce or avoid the need of most costly and less effective remediation programs.

Palabras clave : early intervention; prenatal stress; toxic stress.
