Objective:
To revisit Austregesilo’s pioneering contributions to neurology, highlighting his forward-thinking insights into movement disorders that preceded the dopaminergic era.
Background:
Antonio Austregesilo Rodrigues de Lima (1876 - 1960) is recognized as the founder of Brazilian Neurology and the spiritual father of Brazilian Neurosurgery. In 1912, he became the first Professor of Neurology at the Faculdade de Medicina do Rio de Janeiro, establishing the country’s first neurological school and shaping the foundations of neurological education and clinical reasoning in Latin America.
Design/Methods:
Historical narrative review integrating original bibliographic production by Austregesilo and his collaborators and contemporary evidence. PubMed and SciELO search (1912-2025) was performed addressing movement disorders, with emphasis on dystonia and antiparkinsonian treatment.
Results:
In 1912, Austregesilo described the Austregesilo-Esposel sign, an alternative to the Babinski reflex elicited by thigh compression: an early recognition of pyramidal–extrapyramidal interplay. In 1928, he published the first documented case of post-traumatic dystonia, anticipating the modern classification of organic dystonias.
In 1945, he advocated the use of atropine and scopolamine to relieve rigidity and tremor in Parkinsonian patients. Though developed before the dopaminergic era, this approach accurately predicted a neurochemical imbalance between dopaminergic inhibition and cholinergic overactivity within the basal ganglia. Modern antiparkinsonian therapy still employs central anticholinergic agents such as trihexyphenidyl and biperiden, following the same physiological rationale Austregesilo first proposed, decades before dopamine’s role in motor control was elucidated.
Conclusions:
Austregesilo’s clinical reasoning anticipated modern neurochemical models of basal ganglia pathways. His work allowed an intersection between classical neurological semiology and emerging neurophysiology concepts, with a major contribution to what was established as the intellectual and institutional foundations of Brazilian neurology and movement disorder research.
