The purpose of this investigation was to ascertain: (1) the frequency and nature of abnormal mental states in cases of tumor involving the temporal lobe; (2) the diagnostic value of such states as localizing symptoms; (3) whether the frequency and nature of the mental symptoms of a tumor involving the temporal lobe only differ from those of a tumor of the temporal lobe and its adjacent areas, and (4) whether there is any significant difference in frequency and nature between the mental symptoms of tumor of the temporal lobe and those of tumor of the frontal lobe.1
A survey of the more recent literature on the symptomatology of tumor of the temporal lobe discloses that some observers have reported the presence of mental symptoms in only 8 per cent of cases while others had found them in every case. This statistical disparity is encountered in the reports not only
