Hydrocephalus is a condition of an excessive of cerebrospinal fluid in the brain. In this paper, we try to simulate the behaviour of hydrocephalus condition in infants by using a hydro-elastic model which is combined by the orthotropic elastic skull and by the addition of the suture that divide the skull into two lobes. The model then gives predictions for variaous condition of hydrocephalus by varying the cerebral aqueduct diameter arachnoid villi resistant. In the case of stenosis aqueduct, we also vary the time constant and elastic modulus of the brain parenchyma. The results show that as the diameter decreasing, the value of displacements and intraventricular pressure are increasing. The significant value of the displacement and intraventricular pressure are achieved, in this case, when the cerebral aqueduct is as resistant as or more resistant than brain parenchyma. The decrement of elastic modulus of stenosis aqueduct case causes the large displacement of brain parenchyma and skull, but did not influence the displacement of ventricle wall. The smaller time constant causes the increment of intraventricular pressure and displacement more rapidly than the higher one which causes the displacement has smaller value for smaller time constant. The increment of arachnoid villi resistant give no significant value of intraventricular pressure and the displacement of ventricle wall, brain parenchyma, and skull when we use normal cerebral aqueduct diameter.
