Monrad-Krohn was interested in various
language disorders, in particular
dysprosody, and he introduced the term
aprosody to that field. He wrote a book entitled 'The Clinical Examination of the Nervous System', of which seven editions were reproduced as texts to be read in the study of the area. These are now considered antiquarian, and are collector's items. He was also particularly interested in
reflexes. His 1918 thesis was based on observations of abdominal reflexes. In 1922 he undertook a major study of facial reflexes in patients with
leprosy, and the paralysis displayed by them. The facial mimicry displayed by them despite their paralysis, termed "paradoxical emotional hypermimia" was given the name "Monrad-Krohn Sign". Over the course of his career he received the following awards and appointments: •
