The oculo-finger reflex in post-coma parkinsonism was first described by Nathalie Zand in 1930, marking a significant contribution to clinical neurology. A Polish physician who operated in the early twentieth century, she maintained an extensive research output while working at the Jewish Hospital in the Czyste neighborhood of Warsaw during the tumultuous era of the Second World War.
Medical Education and Early Research
Born in 1883 in Warsaw to parents David Zylberlast and Emilia, née Batawia, Zand completed her initial schooling at the Second Women's Junior High School in 1899. She pursued higher studies at the University of Geneva. Her doctoral dissertation, supervised by Edouard Martin, centered on a case of myeloid leukemia observed in a nine-month-old infant. In 1907, she completed her medical diploma before passing the state examination at the National University of Kharkiv in Ukraine.

Zand became a notable contributor to French medical journals and conducted her professional practice alongside Edward Flatau at the Jewish Hospital in Warsaw. Her research covered diverse areas including encephalitis, pyramidal pathways, and the choroid plexus of the ventricles. In 1921, she partnered with Flatau to publish findings regarding three distinct forms of meningeal reaction occurring in patients with tuberculosis. Her 1930 volume, Les plexus choroïdes: Anatomie, physiologie, pathologie, featured a foreword by Gustave Roussy, cementing her academic standing in the field of neuropathology.
Professional Versatility and Final Years
Throughout her career, Zand published over 100 research papers using variations of her name, including Zylberlast-Zand and Zandowa. Beyond her medical writing, she ventured into literature, releasing a novel titled Nowa Legenda under the pseudonym Maria Quieta in 1933. During the Nazi occupation of Warsaw, she remained in the city, forced into the ghetto where she continued to provide medical care. She was detained on the night of 23 September 1942 and transferred to the Pawiak prison, where she died.
