The aetiology of the non-communicating patients was classified as aqueductal stenosis, fourth ventricle outflow blockage, and foramen of Monro stenosis. The aetiology of the NPH patients was classified as idiopathic, subarachnoid haemorrhage, post-traumatic, or postoperative after tumour surgery. The clinical outcome after surgery is reported as scores on psychometric, wakefulness, gait, and balance indices. The overall postoperative improvement is expressed as the mean of the differences between preoperative and postoperative scores on the four indices. | |||||||||||||
