Besides, the obstruction can also occur outside of the ventricles in the subarachnoid space as a result of debris or adhesions from a prior hemorrhage, infection, or inflammation (Blumenfeld, 2010 p. 156). A decrease in CSF absorption can also cause hydrocephalus when arachnoid granulations are damaged or clogged, but this can be hard to distinguish from obstruction of CSF flow due to similar causes like prior hemorrhage, infection, or inflammation (Blumenfeld, 2010 p. 156). For this reason, hydrocephalus is often separated into two categories: communicating hydrocephalus which can be caused by impaired CSF reabsorption, obstruction of flow to subarachnoid space, or by CSF overproduction and noncommunicating hydrocephalus which is due by an obstruction of flow within the ventricular system (Blumenfeld, 2010 p. 156). Signs and symptoms include headaches, nausea, vomiting, cognitive impairment, and sixth nerve palsies (Blumenfeld, 2010 p. 156). Besides, patients who have hydrocephalus may present with an unsteady magnetic gait (feet barely leaving the floor) and incontinence (involuntary control of urine and bowel movements) (Blumenfeld,
