We found at the initial examination that the average intelligence quotient for the entire group was 74, with a range of from 35 to 130. (The majority of those who were retested at a later date did not show a decline in the intelligence quotient.)

To date, 35 of these patients have been tested, each from three to eight times, at intervals of a year or more, with the Stanford revision of the Binet test for general intelligence. Table 1 shows the results of these tests and includes data on the type of epilepsy, the duration of the attacks, expressed in years, the initial intelligence quotient and the fluctuation of the quotient from test to test.
