When to see a neurosurgeon

Most people hear the word neurosurgery and think only of a major brain operation. That is one part of the work. A neurosurgeon also sees everyday problems of the spine, trapped nerves, headaches that need a scan, and children born with a problem of the brain or spinal cord. A visit is often a diagnosis and a plan. Surgery is one option, and it is not the first option for everyone.

What neurosurgery is Neurosurgery is the branch of medicine that deals with the brain, the spinal cord, the spine, and the nerves that leave them. A neurosurgeon trains first as a doctor, then spends years learning to examine these problems, read MRI and CT scans, and operate when an operation is the safer choice.

The brain sits inside the skull and controls movement, speech, memory, vision, and balance. The spinal cord runs down the centre of the spine and carries messages between the brain and the body. Discs sit between the bones of the spine and can bulge or wear out. Nerves leave the spine and travel into the arms and legs. Pain, numbness, weakness, or trouble walking can start in any of these places. The job of the visit is to find which one.

Neurosurgeon and neurologist A neurologist and a neurosurgeon both treat the nervous system. A neurologist usually manages conditions with examination, scans, and medicine. Epilepsy, migraine, stroke recovery, and many nerve diseases stay with a neurologist.

A neurosurgeon is asked when a structural problem may need an operation, or when someone must decide whether surgery can be avoided. A disc pressing on a nerve, a tumour, bleeding in the brain, a blockage of fluid inside the skull, and some injuries of the spine are typical reasons. The two specialists often work together. Seeing a neurosurgeon does not mean you have already been booked for theatre.

Common reasons to book a visit Back or neck pain that spreads into an arm or a leg, with numbness or weakness Pain that is worse at night, or that stops you walking the distance you could walk last month A change in bladder or bowel control together with back pain or leg weakness A seizure, or jerks of the body that are new A headache that is sudden and severe, or a headache with vomiting, double vision, or confusion Weakness, numbness, or clumsiness on one side of the body Trouble with balance, speech, or vision that is new A head injury followed by drowsiness, repeated vomiting, or a worsening headache An MRI or CT report that mentions a disc, a tumour, bleeding, a cyst, or pressure on a nerve A child with a swelling on the head or spine, a large head, or delayed movement that a paediatrician wants a surgeon to review Spine problems The most common clinic visits are for the spine. A prolapsed, or slipped, disc can press on a nerve. People feel pain in the lower back that shoots down one leg, or neck pain that runs into the shoulder and hand. Tingling, numbness, and a weak foot or grip can follow.

Wear of the spine, called degenerative disease, narrows the canal where the nerves sit. Walking may become shorter and shorter, with relief when the person sits or bends forward. Some spines become unstable, and selected patients need fixation, which means an operation to steady those bones.

Not every worn disc needs surgery. Many settle with time, pain relief, and physiotherapy. A surgeon is useful when pain will not settle, when weakness is increasing, or when the scan and the examination point to a nerve that is stuck.

Brain conditions Brain tumours, bleeding, infection, and some birth conditions also belong in this clinic. A tumour may be found after a seizure or a slowly worsening headache. Some are benign and grow slowly. Some are cancer, including cancers that have spread from elsewhere. Treatment can be surgery, or a plan made with cancer doctors, or watching a small growth with repeat scans.

Bleeding in or around the brain is an emergency, not a routine appointment. So is a serious head injury. A brain abscess, which is a pocket of infection, also needs urgent hospital care. Fluid that builds up inside the skull, called hydrocephalus, can cause headache, vomiting, and unsteadiness, and in babies a rapidly growing head.

Other problems people ask about include arteriovenous malformations, which are tangled blood vessels, epilepsy that continues despite medicine, tremor and Parkinson disease in selected cases, and hormone conditions linked with a growth near the pituitary gland.

Children Some neurosurgical conditions start before birth or in early childhood. Myelomeningocele and encephalocele are openings along the spine or skull. Cerebral palsy is a movement condition that starts early in life. A neurosurgeon may advise on tightness, the shape of the spine, or a shunt for fluid on the brain. Parents should bring any earlier paediatric letters and scans.

What happens at the first appointment The visit starts with the story. When did it begin, what makes it worse, and what has already been tried? A focused examination follows: strength, feeling, reflexes, walking, and, when the problem is in the head, speech, vision, and coordination.

Bring the actual MRI or CT films if you have them, not only the written report. Bring blood tests, old prescriptions, and a list of current medicines. For a child, bring growth and pregnancy notes if you still have them.

Many first visits end with one of four plans: medicine and time, physiotherapy, a new or better scan, or a discussion of surgery. If an operation is suggested, you should hear why, what the other choices are, and what the main risks are. It is reasonable to ask whether the operation is needed now, later, or not at all.

How to prepare Write down the symptom in one sentence, the date it started, and whether it is getting worse. Note any fall, fever, fit, or new medicine. Wear clothes that let the doctor see your walk and examine your back or neck. Come with a family member if decisions about surgery may come up. They will remember details you may miss.

When to go to emergency care first Do not wait for a clinic slot if any of these are happening now: A sudden, worst-ever headache A new seizure, or a seizure that will not stop Weakness or numbness on one side, a drooping face, or trouble speaking A serious head injury, repeated vomiting, or increasing drowsiness Fever with a stiff neck, confusion, or a rash Rapidly worsening back pain with loss of bladder or bowel control, or weakness in both legs A child who is unusually sleepy, vomiting often, or whose head is swelling quickly Go to an emergency department. The clinic can review the person after they are safe.

A visit is a plan, not a promise of an operation People delay because they fear they will be sent straight to surgery. In practice, the useful outcome is often clarity. You leave knowing what the scan means, which symptoms matter, and what to do if things change. If something about your brain, your spine, or a nerve does not feel right, a neurosurgical opinion is a reasonable next step.
