Neurocristopathy refers to a range of developmental disorders that affect the nervous system and other systems such as the cardiovascular and craniofacial systems. Synonyms for neurocristopathy include neurocristopathies and neurocristic disorders. Other related terms include neurocristal syndromes and neurocristic dysplasias. These conditions result from the abnormal development of neural crest cells during embryonic development, which normally give rise to various tissues and organs in the body. Common examples of neurocristopathy include neurofibromatosis, Hirschsprung's disease, and Waardenburg syndrome. Symptoms and severity of these disorders can vary widely, and there is currently no cure for neurocristopathy.
