What Is a Neurosurgeon?
Neurosurgeons diagnose and treat disorders of the brain, spine and nervous system — the control center for everything the human body does. Here is what the specialty involves, the training it demands and the Texas surgeons who practice it.
The specialty
What Is Neurosurgery?
The central nervous system — the brain and spinal cord — controls the body’s most essential functions: breathing, heartbeat, movement, sensation and consciousness itself. Because these systems leave almost no margin for error, even a minor mistake can lead to loss of function, paralysis or death.
Neurosurgeons treat disorders of the entire nervous system — the brain, the spine and the peripheral nerves that run through the arms and legs. Their work spans brain tumors, cerebrovascular conditions, spinal disorders and trauma, functional and pediatric neurosurgery, pain management and nerve repair, often in emergencies and at any hour.

Neurosurgeons vs. Glioblastoma: Research, Innovation, Hope
Neurosurgeons do more than operate — they are at the forefront of research against some of the most aggressive cancers.
At its 2026 Annual Conference in Houston, the Texas Association of Neurological Surgeons highlighted one of the world’s leading health care hubs. Yoshua Esquenazi, MD, of the University of Texas Health Science Center at Houston shares insights into the evolving field of neurosurgical oncology.
Dr. Esquenazi discusses emerging research into the microbiome and its potential to enhance treatment, improve survival and shape the future of care for patients facing brain tumors.

The making of a neurosurgeon
Neurosurgery Training
Neurosurgery is often called the most demanding specialty in medicine — and it requires one of the longest, most rigorous training pathways of any field. Unlike most of the body, the nervous system does not tolerate mistakes. An error in judgment or technique can carry life-altering consequences for a patient.
After four years of medical school, a neurosurgeon completes a seven-year residency — one of the longest in medicine — layered with national board examinations along the way, and many go on to additional subspecialty fellowship. All told, the path can span up to 14 years of training before a neurosurgeon practices independently.

A Day in the Life of Neurosurgery: From Emergency Trauma to AI Breakthroughs
A neurosurgery resident takes us inside the OR — and into the future of the field.
Alex Flores, MD, a neurosurgery resident at Baylor College of Medicine, walks through one of medicine’s most demanding specialties. From brain tumors and aneurysms to spine trauma and peripheral nerve surgery, Dr. Flores breaks down the full scope of what neurosurgeons handle — including the gunshot wounds, car wrecks and round-the-clock emergency calls that make the job as intense as it is rewarding.
He also explores how artificial intelligence is transforming stroke care — identifying early ischemic strokes faster and more accurately, and getting patients into the interventional suite before it is too late.

Why This West Texas City Is a Lifeline for Rural Neurosurgery Patients
For rural communities, specialized care can mean the difference between staying close to home and traveling hundreds of miles.
Kristopher Lyon, MD, is a neurosurgeon based in Abilene, Texas — a regional hub serving patients from more than 20 surrounding counties. He shares what it is like to practice neurosurgery in a community setting, why keeping patients local matters and how his work helps rural Texans get specialized care without leaving the region they call home.
Many of his patients already drive over an hour to reach him. Without a neurosurgical presence in Abilene, they would have no choice but to be transferred even further — away from their families, their support systems and their communities.

Who we are
TANS: The Unified Voice of Texas Neurosurgeons
The Texas Association of Neurological Surgeons brings together neurosurgeons from every corner of the state under one banner — academic and private practice, metro and rural, veteran surgeons and residents just entering the field.
TANS advances the specialty through education, advocacy at the Texas Capitol and a shared commitment to protecting patients’ access to high-quality neurosurgical care. By speaking with one voice, Texas neurosurgeons shape the policies and standards that define how the specialty is practiced across the state.
