Both them are caused by damaged cerebrospinal fluid re-absorption in the absence of any cerebrospinal fluid-flow obstruction between the ventricles and subarachnoid space. Communicating hydrocephalus has many different neurologic conditions such as subarachnoid and intraventricular hemorrhage, meningitis and congenital absence of arachnoid villi. In some case, the special form of communicating hydrocephalus is normal pressure hydrocephalus which causes thickening of the arachnoid leading to blockage of the return-flow channels that filled with the cerebrospinal fluid and the intercranial pressure stays in balance. Non-communicating hydrocephalus is also called obstructive hydrocephalus that the cerebrospinal fluid in the ventricles cannot reach the subarachnoid space, which results from obstruction of inter-ventricular foramina, cerebral aqueduct, or the outflow foramens of the fourth ventricle. The area of the cerebral aqueduct will show the most common non-communicating
