In babies, it may be seen as a rapid increase in head size. Other symptoms may include vomiting, sleepiness, seizures, and downward pointing of the eyes. [1] Hydrocephalus can occur due to birth defects or be acquired later in life. [1] Associated birth defects include neural tube defects and those that result in aqueductal stenosis.
An estimated 15% of preterm infants who survive develop cerebral palsy and 27% of the infants who survive experience moderate to severe neurosensory deficits by the time they reach 18–24 months old. [7] Prognosis is very poor when IVH results from intracerebral hemorrhage related to high blood pressure and is even worse when hydrocephalus ...
Hydranencephaly is an extreme form of porencephaly, which is characterized by a cyst or cavity in the cerebral hemispheres. [citation needed]Although the exact cause of hydranencephaly remains undetermined in most cases, the most likely general cause is by vascular insult, such as stroke, injury, intrauterine infections, or traumatic disorders after the first trimester of pregnancy.
Encephaloceles are often accompanied by craniofacial abnormalities or other brain malformations. Symptoms may include neurologic problems, hydrocephalus (cerebrospinal fluid accumulated in the brain), spastic quadriplegia (paralysis of the limbs), microcephaly (an abnormally small head), ataxia (uncoordinated muscle movement), developmental delay, vision problems, mental and growth retardation ...
Many organ systems are affected by triploidy, but the central nervous system and skeleton are the most severely affected: . Common central nervous system defects seen in triploidy include holoprosencephaly, hydrocephalus (increased amount of cerebrospinal fluid within the brain), ventriculomegaly, Arnold–Chiari malformation, agenesis of the corpus callosum and neural tube defects.

Cerebral edema, brain hemorrhages and hydrocephalus exert pressure on brain tissue and impede their absorption of oxygen. Histotoxic hypoxia – Oxygen is present in brain tissue but cannot be metabolized by the brain tissue. Cyanide poisoning is a well-known example.
