The problem of retrograde amnesia (R. A. ) has long been discussed but certain details yet remained unclarified. For seven years, the author has investigated 847 cases of the head injured presenting R. A. in the Neuro-psychiatric Department of Kansai Medical School. In this survey, however, the cases in the acute stage of the injury and those with amnestic syndrome have carefully been excluded from the materials.The results are as follows:1) The correlation between R. A. and post-traumatic amnesia (P. T. A. ) is hardly recognized as Russell has already pointed it out. R. A. is seldom found in cases with P. T. A. of short duration (less than an hour). In addition, the presence of long-lasting R. A. has no direct relationship with the duration of P. T. A.2) Precise clinical investigation of 13 cases with fairly long-lasting R. A. (more than an hour) has resulted in the following findings.a) Statistically, it might be probable that manifest and long-lasting R. A. tended to be found in car drivers.b) Various offenses of the traffic law or responsibility due to unskilful driving technique and consequently certain feelings of guilt are frequently found in those cases, and expectation of compensation is never observed among them.c) Organic damage of brain, especially of m nemic system, is not always suspected in them.d) The presence of such type of R. A. might rather be considered in connection with character traits than with the factors of intelligence of the patients.e) Treatment of R. A. was intended by means of psycho therapy in eight cases: sufficient or remarkable recovery of memory were obtained in two cases by intensive suggestion and five by hypnotherapy.
