Etiology and Pathophysiology of the Spina Bifida [chapter]

René Opšenák, Romana Richterová, Branislav Kolarovszki
2021 Spina Bifida and Craniosynostosis - New Perspectives and Clinical Applications [Working Title]  
The spina bifida is a congenital anomaly that results in an abnormal formation of the spine and the spinal cord.  ...  Genetic, nutritional and environmental factors play a role in the etiology and pathogenesis of the spina bifida.  ...  Overall reduction in white matter and increased neocortical thickness in the frontal lobes suggest that the spina bifida reflects a long-term disruption of brain development that extends far beyond the  ...
