The Alternating Asphygmo-Pyramidal Syndrome, identified in 1962 during the examination of carotid artery occlusions, remains a primary contribution by Ion N. Petrovici to the field of neurology. His clinical research bridged the gap between Romanian medical training and German academic neurology, shifting diagnostic practices regarding cerebrovascular disease and hemispheric brain function throughout the late twentieth century.
Early Education and Romanian Training
Born in 1929 in Ploiești, Romania, Petrovici completed his foundational studies at the Saints Peter and Paul High School in 1947. He pursued medical training at the University of Bucharest, eventually earning his MD. His development as a specialist occurred at the Department of Clinical Neurology under the Romanian Academy of Sciences, where he studied under Arthur Kreindler and Vlad Voiculescu. He achieved specialist status in 1959. Between 1964 and 1969, he served as the chief of pre-operative diagnosis at the University of Bucharest Clinic of Neurosurgery under Constantin Arseni, co-authoring the 1965 text Vascular Diseases of the Brain and of the Spinal Cord with Arseni and Frank Nass.

In 1969, Petrovici emigrated to Germany to work at the Max Planck Institute for Brain Research in Cologne under the supervision of Klaus-Joachim Zülch. During this tenure, he shifted his focus toward applying research methodology to specific neurologic pathologies. He achieved his habilitation in 1978, securing the venia legendi required for his academic advancement within the German university system.
Academic and Clinical Leadership
Petrovici joined the faculty of the University of Cologne, attaining the rank of professor of neurology and psychiatry in 1983. Two years later, he assumed the role of director for the Department of Neurology at Merheim Hospital, a position he occupied until his retirement in 1994. His academic work included studies on seizure disorders, malignant brain tumor therapy, and interhemispheric transfer of learning. Following his departure from clinical duties, he was named an honorary member of the Romanian Academy of Sciences.
Professional Affiliations
His influence extended through membership in international scientific organizations, including the Deutsche Gesellschaft für Neurologie, the Deutsche Gesellschaft für Klinische Neurophysiologie, the Società Italiana di Neurologia, the European Society of Neurology, and the New York Academy of Sciences. Additionally, he served as a Fellow of the Royal Society of Medicine. He died in 2021 at the age of 92.
