This paper describes some of the more common patterns in neurobehavioral deficits and their underlying neuroanatomical basis in myelomeningocele (MMC). Patients with MMC can face a lifetime of specific organ system dysfunction, chief among them spinal cord malformations, orthopedic issues, hydrocephalus, and urological disabilities. In addition, patients can experience specific patterns of neurobehavioral difficulties due to the changes in neuroanatomy associated with the open spinal defect. Although there is variability in these patterns, some trends have been described among MMC patients. It is thought that early recognition of these potential neurobehavioral deficits by treating neurosurgeons and other members of the treatment team could lead to earlier intervention and positively impact the overall outcome for patients. Neurodevelopmental and neurobehavioral follow-up assessments are recommended to help guide planning for relevant treatments or accommodations.
