Summary of the Tenth Princeton Conference on Cerebral Vascular Diseases, January 7-9, 1976

FOLLOWING REMARKS by Dr. Scheinberg, a presentation, "Frequency and Symptom Analysis of Transient Ischemic Attacks: A Cooperative Hospital Study," was given by Dr. Mark L. Dyken (Professor and Chairman, Department of Neurology, Indiana University Medical School, Indianapolis, Indiana). In the limited time available, Dr. Dyken could present only some general comments concerning the 512 transient ischemic attack (TIA) patients collected during 21 months' time in the various centers; the average interval of follow-up apparently was 14.3 months. The study was designed to determine the current medical practice in handling TIA and the reliability of diagnosis and to compare varieties of therapy. Four hundred patients had carotid TIAs and 112 had vertebrobasilar attacks. There was high blood pressure in 52% of the group and ischemic heart disease in 36%. Bruits (not defined) were noted in 289 patients, and of these only 67 were appropriate to the side of the symptoms. Retinal artery pressures were obtained in only 20% of the patients but were abnormal in 94% of those studied. Approximately 27 patients had retinal emboli; apparently the examination for these was infrequent, as was obtaining retinal artery pressures. Four
