The human brain is medicine´s last frontier and the knowledge of our command center is increasing more and more, including ailments and conditions that it may suffer. One of them is the hydrocephalus syndrome with normal pressure, which is characterized by accumulation of cerebral fluids without increasing pressure, which usually affects adults. If today contemporary medicine can diagnose and treat this syndrome, it is thanks to Dr. Salomón Hakim, who discovered it. That is why it is called the Hakim Syndrome. Born in Barranquilla, Colombia, he graduated in Medicine at the National University of Bogotá. He travelled to the United States to specialize in neurosurgery at the Lahey Clinic and the Massachusetts General Hospital in Boston. Salomón not only helped to discover this frequently misdiagnosed syndrome, but he also designed a valve to help alleviate it, which opened the doors to him to the history of neuroscience. Placed surgically under the skin behind the ear, the function of the valve is to allow the excess cerebral fluid towards the thorax or the abdomen of patients with hydrocephaly.
