Abstract:
:The developing brain in utero and during the first years of life is highly vulnerable to environmental influences. Experiences occurring during this period permanently modify brain structure and function through epigenetic modifications (alterations of the DNA structure and chromatin function) and consequently affect the susceptibility to mental disorders. In this review, we describe evidence linking adverse environmental variation during early life (from the fetal period to childhood) and long-term changes in brain volume, microstructure, and connectivity, especially in amygdala and hippocampal regions. We also describe genetic variations that moderate the impact of adverse environmental conditions on child neurodevelopment, such as polymorphisms in brain-derived neurotrophic factor and catechol-O-methyltransferase genes, as well as genetic pathways related to glutamate and monoaminergic signaling. Lastly, we have depicted positive early life experiences that could benefit childhood neurodevelopment and reverse some detrimental effects of adversity in the offspring. WHAT THIS PAPER ADDS: Prenatal, peripartum, and postnatal adversities influence child behavior and neurodevelopment. Exposure to environmental enrichment and positive influences may revert these effects. Putative mechanisms involve alterations in neurotrophic factors and neurotransmitter systems. New tools/big data improved the understanding on how early adversity alters neurodevelopment. This permits better translation/application of the findings from animal models to humans. :INFLUENCIAS AMBIENTALES TEMPRANAS EN EL DESARROLLO DE LA ESTRUCTURA Y FUNCIÓN DEL CEREBRO DE LOS NIÑOS: El cerebro en desarrollo en el útero y durante los primeros años de vida es altamente vulnerable a las influencias ambientales. Las experiencias que se producen durante este período modifican permanentemente la estructura y función del cerebro a través de modificaciones epigenéticas (alteraciones de la estructura del ADN y la función de la cromatina) y, por consiguiente, afectan la susceptibilidad a los trastornos mentales. En esta revisión, describimos la evidencia que vincula la variación ambiental adversa durante la vida temprana (desde el período fetal hasta la infancia) y los cambios a largo plazo en el volumen cerebral, la microestructura y la conectividad, especialmente en las regiones de la amígdala y el hipocampo. También describimos variaciones genéticas que moderan el impacto de las condiciones ambientales adversas en el desarrollo neurológico infantil, como los polimorfismos en los genes del factor neurotrófico derivado del cerebro y de la catecol-O-metiltransferasa, así como las vías genéticas relacionadas con el glutamato y la señalización monoaminérgica. Por último, hemos descrito experiencias positivas de la vida temprana que podrían beneficiar el desarrollo neurológico infantil y revertir algunos efectos perjudiciales de la adversidad en la descendencia. :INFLUÊNCIAS AMBIENTAIS PRECOCES NO DESENVOLVIMENTO DA ESTRUTURA E FUNÇÃO CEREBRAL EM CRIANÇAS: O cérebro em desenvolvimento no útero e durante os primeiros anos devida é altamente vulnerável a influências ambientais. Experiências que ocorrem durante este período modificam permanentemente a estrutura e função cerebrais por meio de modificações epigenéticas (alterações da estrutura do DNA e função da cromatina). Consequentemente, afetam a suscetibilidade a desordens mentais. Nesta revisão, nós descrevemos a evidência relacionando variação ambiental adversa durante o início da vida (do período fetal à infância) e mudanças de longo prazo no volume, microestrutura e conectividade cerebral, especialmente nas regiões da amídala e hipocampo. Também descrevemos variações genéticas que moderam o impacto de condições ambientais adversas no neurodesenvolvimento infantil, tais como polimorfismos em fatores neurotróficos derivados do cérebro, e genes catechol-O-metiltransferases, assim como vias genéticas ligadas à sinalização por glutamato e momonoaminérgica. Por fim, descrevemos experiências precoces positivas que podem beneficiar o neurodesenvolvimento infantil e reverter alguns efeitos detrimentais da adversidade na prole.
