1. Psychological testing were applied to 20 hydrocephalic patients who had had shunt operations before 1973.Thirty percent of the patients showed IQ above 80, 15% between 79 and 70, and 55% below 69. Considering the cause of hydrocephalus, the best result was seen in the patients with unknown etiology. The next was in meningomyelocele. The worst was in meningitis.2. There was a correlation between frontal cortical thickness and mental development. Patients with cortical thickness of less than 0.8 cm showed poor developement.3. Mental developement cannot be evaluated sufficiently by IQ score alone. After analysing the pattern of subtest score, further systemic tests must be performed. On the basis of these examinations, mental rehabilitation or educational therapy are indicated.
