Erico R. Cardoso M.D.

I see my practice as part advocate for my patients’ health, and part specialist dedicated to fighting diseases and accidents that affect the nervous system and brain.

As a specialist, the mission of my practice is to reverse the disease process and return my patients to normal life. To this end I bring many years of experience as a neurosurgeon and avid, continuing research in the field.

As an advocate, I take seriously how deeply patients and their families are affected when they come to see me. I commit to working tirelessly to reduce the inconvenience and interruption to their daily lives.

I wholeheartedly harness all my skills and compassion to ameliorate my patients’ suffering and improve their quality of life.

Dr. Cardoso has studied and trained in a wide variety of neurosurgical practices from around the world. A native of Brazil, he completed his initial neurosurgical residency there. He was accepted soon after to the University of Ottawa, Canada where he went through an intensive training in general surgery and neurosurgery, obtaining a Master’s degree in Neuro-Anatomy. He then went on to obtain two specialty fellowships in Neurosurgery; the first in vascular neurosurgery in Ontario, Canada; the second in pituitary diseases in Glasgow, Scotland. After a few years of neurosurgical practice in Canada, Dr. Cardoso was invited to work as a guest surgeon at the University of Umea, Sweden.

In the early years of his academic career Dr. Cardoso conducted extensive bench and clinical research in diseases related to abnormalities of the cerebral spinal fluid (CSF), such as hydrocephalus, Arnold-Chiari malformation, benign intra-cranial hypertension, shunting and syringomyelia. His award-winning expertise in these areas soon garnered invitations to practice in the United States. Since 1991 Dr. Cardoso has concentrated his efforts in the practice of general neurosurgery in Brooklyn, New York.

Dr. Cardoso has been repeatedly rated one of New York City’s Top Doctors by both New York Magazine and Castle Connolly, a national arbiter of America’s top physicians. But perhaps the most meaningful validation of confidence in his capabilities is the number of respected physicians throughout the metropolitan area who have repeatedly trusted the health of their own family members to his care.
