16802 Brain Surgery

Overview

Brain surgery (also called neurosurgery) is an operation where a specially trained surgeon works on your brain, the skull around it, or the tissues and blood vessels nearby. It is done for many different reasons — for example, to remove a growth, stop bleeding, repair a blood vessel, drain an infection, relieve pressure, place a small device, or take a tiny sample of tissue to look at under a microscope (this sample is called a biopsy). Not every brain problem needs surgery, and surgeons always weigh the benefits against the risks with you.

Brain surgery is uncommon compared with everyday operations such as knee or hernia surgery, but specialist neurosurgical teams perform these operations regularly. Thousands of people have brain surgery every year and go on to recover well.

Brain surgery can be needed at any age, from babies to older adults. The reasons vary by age: children are more likely to need surgery for birth-related problems,某些 congenital conditions or certain childhood tumours, while older adults are more likely to need it after a stroke-related bleed, for a tumour, or for a blood vessel problem. Your overall health matters more than your age when a team plans an operation.

Symptoms

Common symptoms

• Headaches that keep getting worse over days or weeks, especially in the morning or when lying down
• Seizures (fits) — a first seizure always needs medical attention
• Weakness, numbness or clumsiness in an arm, leg or one side of the face
• Changes in vision, such as blurring, double vision or losing part of your field of view
• Trouble speaking, finding words, or understanding what others say
• Memory problems, confusion, or changes in personality and mood noticed by people close to you
• Feeling sick or being sick, especially in the morning
• Problems with balance or walking
• Hormone-related symptoms such as unusual tiredness, weight change or changed periods (when the pituitary gland near the brain is involved)

Symptoms in children

• In babies: an unusually large or quickly growing head, a bulging soft spot on the head, poor feeding, repeated vomiting, or being very sleepy or very irritable
• In older children: morning headaches or headaches that wake them at night, vomiting without a stomach bug, worsening school performance, or new behaviour changes
• Seizures, or brief spells where the child stares or becomes limp
• Losing skills they already had, such as walking or talking clearly
• Changes in sight, balance or coordination, or a squint that appears suddenly

Symptoms in older adults

• Confusion or memory problems that are blamed on 'just getting older' but are getting worse
• Falls, unsteadiness, or a change in how someone walks
• New weakness on one side, or a drooping face
• Headaches, drowsiness or personality changes
• Symptoms that come on slowly and are easy to miss — it can help to write them down before an appointment

Causes

Main causes

• Growths inside the head — some are harmless (benign) and some are cancer; surgery may be to remove them, shrink them, or take a sample
• Bleeding inside the head, caused by a head injury or a burst blood vessel
• Problems with blood vessels, such as a bulging weak spot (aneurysm) or a tangled knot of vessels (arteriovenous malformation)
• Buildup of fluid inside the head (hydrocephalus), which can be relieved with a thin tube called a shunt
• Infections such as an abscess or infected fluid collection that needs draining
• Pressure on nerves — for example, the nerve pain called trigeminal neuralgia
• Severe epilepsy that does not improve with medicines, where removing a small area of brain tissue may help
• Conditions such as Parkinson's disease, where tiny implants can be placed to help control symptoms

Risk factors

• A previous head injury, especially one that caused a bleed
• High blood pressure over many years, which weakens blood vessels
• Smoking and heavy alcohol use
• A family history of aneurysm or certain inherited conditions
• Previous cancer that has spread to the brain
• A weakened immune system, which raises the risk of infection in the brain
• Some rare genetic conditions, such as neurofibromatosis

When to see a doctor

See a doctor urgently if:

• Any first seizure, or a seizure that is different from your usual pattern
• A headache that is getting worse week by week, or one that wakes you from sleep
• New weakness, numbness, speech trouble or vision change
• Symptoms after brain surgery that are getting worse rather than better
• A wound that looks infected, or fluid leaking from it

Book a routine appointment if:

• Headaches that keep coming back and are not explained
• Memory or concentration problems that are affecting work or daily life
• Changes in balance, walking or coordination
• Symptoms your family has noticed but you have not — it is worth asking them
• A follow-up question about a scan, medicine or operation you have already had

Diagnosis

Brain surgery is not diagnosed — the condition behind your symptoms is. Your doctor starts by talking with you about your symptoms and health history, then does a neurological examination. This checks your strength, reflexes, sensation, balance, coordination, memory and speech, and looks inside your eyes with a small light. If the examination or your history suggests something that needs a closer look, you will be referred for a scan. The results are then discussed by a team of specialists who advise on whether an operation is the best option for you.

Tests that may be done

• A neurological examination in the clinic — simple physical checks of movement, feeling, speech and memory
• CT scan: a quick scan that shows bleeding, fractures or large growths
• MRI scan: a detailed picture of the brain's soft tissue; it is painless but noisy and can take 20 to 45 minutes
• Blood tests to check your general health, clotting and hormone levels
• An EEG (electroencephalogram), which records the brain's electrical activity and helps investigate seizures
• A biopsy, where a tiny sample of tissue is taken and examined in a laboratory
• A lumbar puncture (spinal tap) in some cases, where a small amount of fluid is taken from the lower back
• Pre-operative checks such as an ECG (heart tracing), a chest X-ray and a review with the anaesthetist

What to expect at your appointment

The assessment usually happens over a few appointments rather than all at once. You may be asked to bring a list of your medicines, and it helps to bring someone with you, as it is easy to forget details when you are anxious. Before an operation you will have a conversation about the aims, the risks, the alternatives and what recovery might look like — this is called informed consent, and you are free to ask as many questions as you need and to take time to decide.

Treatment

Treatment depends completely on the reason surgery is being considered. Some people need an operation quickly, for example to relieve pressure or stop bleeding. For others, doctors may suggest watching and scanning regularly, or using other treatments first. Surgery is usually one part of a wider plan that can include medicines, radiotherapy, rehabilitation and follow-up scans.

Self-care at home

• Before surgery: follow your team's instructions about eating and drinking, and about which of your usual medicines to take or pause
• Tell your team about all medicines, supplements and herbal products you use, and about any allergies
• If you smoke, stopping even a few weeks before an operation can help your recovery — ask for support to quit
• Arrange help at home for the first couple of weeks: lifts, shopping, cooking and someone to keep an eye on you
• After surgery: keep the wound clean and dry as instructed, and do not wash your hair until you are told it is safe
• Build activity back up slowly. Short walks are usually good; heavy lifting, strenuous exercise and swimming come later, on your team's advice
• Ask about driving. You must not drive until you are told it is safe, and you may need to tell your insurance company and licensing authority
• Write things down, use phone reminders and keep a simple routine — tiredness and fuzzy thinking are common at first and usually settle
• Avoid alcohol while you are recovering and while taking any medicines, unless your doctor says otherwise

Medical treatments

Treatment is tailored to your situation and may include medicines to reduce swelling in the brain, prevent or control seizures, treat infection, ease pain or sickness, or replace hormones if glands near the brain are affected. Other treatments can include radiotherapy, which uses carefully aimed X-rays to treat some growths, and chemotherapy, which uses medicines to attack cancer cells. Rehabilitation is a big part of recovery: physiotherapy helps strength, balance and walking; occupational therapy helps with everyday tasks and thinking strategies; and speech and language therapy helps with talking, swallowing and memory. Your team will explain what each treatment is for and what to expect.

When is surgery considered?

Surgery may be suggested when a scan or examination shows a problem that could damage the brain or nervous system if left alone, when pressure inside the head needs relieving, when there is bleeding or infection to clear, when a sample is needed to plan treatment, or when symptoms such as seizures are not controlled with medicines. The decision is made together with you by a specialist team. It is always fair to ask why surgery is being recommended, what the alternatives are, what happens if you wait, and what the realistic benefits and risks are for someone like you.

Living with this condition

The first few weeks at home are usually about rest, wound care and gentle routine. Tiredness is very common after brain surgery and can feel frustrating — it often comes in waves, and planning short activities with rests in between helps. You may notice changes in memory, concentration, word-finding or mood. These often improve over weeks and months, and therapy can help. Keep follow-up appointments and any scan dates, and keep a list of questions as they come to you.

Lifestyle tips

• Pace yourself: short, realistic goals each day rather than pushing to catch up
• Keep a simple diary of symptoms, sleep and medicines to share at appointments
• Ask family and friends for specific help — lifts, meals, company — people usually want to help but need to know how
• Return to work gradually; talk to your employer about a phased return and any adjustments
• Avoid situations where a sudden dizzy spell or seizure could be dangerous, such as swimming alone or working at height, until you are cleared
• Keep up any therapy exercises even when progress feels slow

Diet and exercise

There is no special diet that speeds up brain healing, but eating regularly and well helps your energy and immune system. Aim for ordinary balanced meals with vegetables, fruit, whole grains, beans, fish or other protein, and plenty of fluids — constipation is common after surgery and after pain medicines, and fluids plus fibre help. Gentle exercise, such as short flat walks, is usually encouraged once you are home and helps mood, sleep and circulation. Build up slowly and follow your team's advice about when you can return to more vigorous exercise, contact sports or swimming.

Mental health and emotional wellbeing

It is very normal to feel frightened, tearful, angry or numb around brain surgery — before, during and after. Some people feel changed by the experience, worry about scans, or feel alone even when surrounded by people. Some notice changes in mood or personality that are linked to the operation itself. All of this deserves attention, not just patience. Talk to your team: psychological and emotional support is part of good care, and counselling, therapy and support groups genuinely help. If you ever have thoughts of harming yourself, please contact your local emergency number or a crisis line in your country straight away, and tell someone you trust how you are feeling.

Prevention

You cannot prevent most of the conditions that lead to brain surgery, and nothing you did caused the need for it. What you can do is lower your risk of some of them: protect your head with a helmet when cycling, riding a motorbike or playing contact sports, wear a seatbelt, keep blood pressure well controlled, avoid smoking, limit alcohol, and get unusual or worsening symptoms checked rather than putting them off.

Screening programmes

There is no general screening test for brain problems, and routine scanning of people without symptoms is not recommended. Screening may be offered in specific situations — for example, if a close relative has had a brain aneurysm or you have a known inherited condition, or through regular follow-up scans after treatment. Ask your doctor whether any screening applies to you personally.

Complications

If left untreated

• Some growths and blood vessel problems can grow or bleed over time, causing pressure on the brain
• Bleeding or infection inside the head can damage brain tissue and, without treatment, can be life-threatening
• Pressure that is not relieved can cause worsening headaches, sickness, drowsiness and loss of consciousness
• Seizures that are not controlled can affect safety and daily life
• Some problems can cause lasting weakness, speech difficulties or changes in thinking if they are not treated in time

Long-term outlook

Most people who have brain surgery recover well enough to return to much of their normal life, though the pace and extent of recovery vary a great deal depending on the reason for the operation, its size and your general health. Some people recover quickly; others need months of rehabilitation and may live with some lasting changes. Follow-up scans and appointments are part of the plan, not a sign that something is wrong. It is reasonable to feel hopeful — the teams who do this work are highly specialised, and support is available at every stage.
