Question
What are the common causes for the occurrence of hydrocephalus and delayed cognitive development in children?
Answer
Common causes of hydrocephalus include excessive cerebrospinal fluid secretion, impaired absorption of cerebrospinal fluid, and obstruction of cerebrospinal fluid circulation channels. Congenital malformations are also a common cause, which may be related to exposure to certain chemical substances by parents, early pregnancy fever, or the use of certain traditional Chinese medicine. Common malformations include spina bifida, aqueductal stenosis of the midbrain, and vascular anomalies.
