Question

Quizplus · Accepted Answer

Hydrocephaly is the buildup of cerebrospinal fluid in the brain. If not treated, the increased pressure can damage or destroy brain tissue, leading to cognitive impairment and even severe mental retardation. The presence of an extra chromosome (as in Down syndrome), an inherited enzyme deficiency, or nutritional deficiencies may also cause developmental delays or intellectual disabilities, but they are not directly associated with hydrocephaly.
