• The age of the parents appears to play no part in the development of congenital. In the vast majority of the cases reported the mother and father we between the ages of 25-35.
• Only 5% of the cases of hydrocephalus were both the mother and father over the age of 35
• In 68% of the cases the fathers were between the ages of 25-35, with 16% of fathers under 25 and 16% over 35
• In 73% of the cases the mothers were between the ages 25-35, with 24% being under of 25 and the remaining 3% over the age of 35
• Genetics appear to have no bearing on the development of hydrocephalus*. Less than 2% of the respondents in our survey reported that their mother/father or grandmother /grandfather also had hydrocephalus. Only 5.6% of the respondents reported having any relatives with hydrocephalus.
• .6% Reported a mother or father with Hydrocephalus
• .6% Reported grandmother or grandfather with Hydrocephalus**
• 2.5% Reported and Aunt or uncle with Hydrocephalus
• .6% Reported a niece or nephew with Hydrocephalus
• 1.3% Reported a cousin with Hydrocephalus
• There is some evidence from our survey that Hydrocephalus can run in families with 3.15% of the respondents reporting a brother or sister with Hydrocephalus (2 of these cases were twins).

* X Link Hydrocephalus is a rare type of Hydrocephalus that is known to have a genetic link.
** These cases may be the result on Normal Pressure Hydrocephalus which is known to be case by the aging process (in most cases) and not genetically linked.
