Salomón Hakim, MD (1922-2011): A honeymoon with Neurosurgery

Abstract

Salomón Hakim (1922-2011) was a Colombian neurosurgeon and brain scientist This biography examines the social and cultural background through which he emerged as an inquisitive and multi-dimensional surgeon-scientist, and his lifelong contributions to the specialty of neurosurgery. With empirical knowledge in applied medical physics, electronics, electricity and chemistry, he understood the paradoxical phenomenon of symptomatic hydrocephalus with normal cerebrospinal fluid pressure. This ultimately led Hakim to describe in exquisite detail the physics of the cranial cavity and brain hydrodynamics. His name is intertwined with the identification of the entity of a syndrome which had not previously been addressed in the medical literature: Normal Pressure Hydrocephalus (Hakim's syndrome). Additionally, he designed and built various models of valved shunting devices to treat the condition (eg the Hakim programmable valve). Through his selflessness and cogent work, Hakim left a legacy and intellectual heritage that has allowed many colleagues worldwide to save thousands of lives who would be otherwise condemned to oblivion.
