Living with Trigeminal Neuralgia can be exhausting. Often described as electric shock-like pain on one side of the face, it can be triggered by everyday actions such as speaking, brushing teeth or even a light breeze.

For many people, medication provides initial relief. But what happens when it stops working,  or the side effects become unbearable?

If you’re reaching that point, there are still options to explore, including non-invasive treatments that do not involve open brain surgery.

Why does trigeminal neuralgia medication stop working?

The first-line treatment for trigeminal neuralgia is usually anti-epileptic medication such as carbamazepine or oxcarbazepine. These drugs calm the overactive nerve signals responsible for the pain.

However, over time:

• The nerve may become less responsive
• Higher doses may be required
• Side effects may worsen
• Pain episodes may break through despite treatment

Common side effects include fatigue, dizziness, brain fog and imbalance. Some patients feel they are trading pain for a reduced quality of life.

If your pain is returning or medication is no longer tolerable, it’s time for a specialist review.

Should I just increase the dose?

Not automatically, or without medical advice. Increasing the dose may temporarily restore pain control, but higher doses increase the risk of:

• Severe drowsiness
• Liver complications
• Blood abnormalities
• Cognitive slowing

Before escalating medication indefinitely, your case should be reassessed. An MRI scan is often recommended to confirm whether a blood vessel is compressing the trigeminal nerve, which is the most common underlying cause.

The goal is not just to suppress symptoms, but to address the root problem where possible.

What are the next treatment options for trigeminal neuralgia?

If medication fails, treatment typically falls into three categories:

• Microvascular decompression (MVD) surgery
• Percutaneous procedures
• Stereotactic radiosurgery

Each has different benefits and risks.

Is open surgery the only permanent solution for trigeminal neuralgia pain?

Microvascular decompression is considered the most definitive treatment when vascular compression is confirmed. During surgery, a neurosurgeon relieves pressure on the nerve by repositioning the offending blood vessel.

It can offer long-lasting relief. However, it requires:

• General anaesthetic
• A craniotomy (opening the skull)
• Several days in hospital
• A recovery period

For younger, otherwise healthy patients, this may be appropriate. But not everyone is a candidate, particularly older individuals or those with medical conditions that increase surgical risk.

Can Gamma Knife treat trigeminal neuralgia without open surgery?

Yes, and for many patients whose medication has failed, it offers a powerful, non-invasive alternative.

Gamma Knife radiosurgery delivers highly focused radiation to the trigeminal nerve root. The treatment is designed to disrupt the pain signals without requiring an incision.

Key advantages include:

• No general anaesthetic
• No surgical incision
• Same-day discharge
• Minimal recovery time
• Suitable for patients who are not ideal surgical candidates

The procedure is typically completed in a single session. Pain relief is not immediate; improvement often develops gradually over several weeks. Many patients experience significant reduction in attack frequency and intensity.

How effective is radiosurgery for trigeminal neuralgia?

Pain control rates are high, particularly in patients with classical trigeminal neuralgia.

While outcomes vary, many patients achieve:

• Substantial pain reduction
• Reduced reliance on medication
• Improved quality of life

Some may experience mild facial numbness, which in many cases is preferable to severe, uncontrolled pain. Serious complications are uncommon when treatment is delivered by experienced teams.

What if the pain comes back after treatment?

Recurrence can happen with any trigeminal neuralgia treatment, including surgery.

If pain returns after radiosurgery:

• Medication may be reintroduced at lower doses
• Repeat radiosurgery may be considered
• Alternative procedures may be explored

The key is ongoing follow-up and access to a team experienced in managing complex or recurrent cases.

How do I know which option is right for me?

Decision-making should consider:

• Your age and overall health
• MRI findings
• Severity and frequency of pain
• Response to previous treatments
• Your tolerance for surgical risk
• How much the condition is affecting your daily life

You deserve a clear explanation of every option, including the risks, benefits and likely outcomes.

Taking the next step

Trigeminal neuralgia can be debilitating to live with. When medication stops working, frustration and fear are understandable. But effective alternatives exist, including precise, non-invasive treatments designed to restore control.

The most important step is seeking timely specialist advice rather than simply increasing medication and hoping for improvement.

A diagnosis of a pituitary tumour is unsettling: the symptoms can cause practical problems as well as emotional challenges. These tumours sit at the base of the brain, close to the optic nerves and critical hormone-regulating structures.

Many patients assume that brain surgery is the only course of treatment when they first get a pituitary tumour diagnosis. However, there may be other, less invasive options. Here is an overview.

What is a pituitary tumour?

Most pituitary tumours are benign growths known as pituitary adenomas. They arise from the hormone-producing cells of the pituitary gland.

They are broadly divided into:

• Functioning tumours – produce excess hormones (such as prolactin, growth hormone or ACTH)
• Non-functioning tumours –do not produce hormones but may cause symptoms by pressing on nearby structures

Common symptoms include:

• Visual disturbance (due to pressure on the optic nerves)
• Headaches
• Hormonal imbalance
• Fatigue
• Irregular periods or fertility issues

Treatment decisions depend heavily on which type of tumour you have.

When is open surgery recommended for pituitary tumours?

Surgery is often the first-line treatment for larger tumours, especially when:

• Vision is threatened
• There is significant compression of the optic chiasm
• Rapid symptom relief is required
• The tumour is producing excessive hormones that need urgent control

The most common operation is transsphenoidal surgery, performed through the nasal passages rather than through the skull. It is highly specialised and often very effective.

However, even after successful surgery, small remnants of tumour may remain. In some cases, hormone levels do not fully normalise. This is where radiosurgery may play an important role.

Can Gamma Knife treat pituitary tumours without open surgery?

In carefully selected cases, yes. Gamma Knife radiosurgery delivers highly focused radiation to the tumour in a single session. Despite the word “surgery,” there is no incision and no general anaesthetic.

Gamma Knife is most commonly used:

• For small residual tumours after surgery
• For recurrent pituitary adenomas
• When patients are not suitable for surgery
• When patients prefer a non-invasive option
• For certain hormone-secreting tumours that persist despite medication

In selected small tumours that are not compressing the optic nerves, it may be used as primary treatment.

The crucial factor is precision. The pituitary gland sits millimetres away from the optic apparatus and normal hormone-producing tissue. Treatment planning requires detailed MRI imaging and specialist expertise.

How does Gamma Knife work for pituitary adenomas?

During treatment planning:

• High-resolution MRI scans are obtained
• A multidisciplinary team reviews imaging and hormone results
• Radiation dose is carefully calculated to protect surrounding structures

The Gamma Knife system directs multiple beams of radiation to converge on the tumour. Each individual beam is low dose, but where they meet, the dose is strong enough to control tumour growth.

The goal is:

• To stop tumour growth
• To gradually reduce tumour size
• To lower hormone production in functioning adenomas

Unlike surgery, results are not immediate. Hormone levels may take months, sometimes longer, to normalise.

What are the advantages of avoiding open surgery?

For suitable patients, radiosurgery offers:

• No surgical incision
• No hospital stay in most cases
• No general anaesthetic
• Minimal recovery time
• Reduced risk of surgical complications
• Most patients return to normal activities within a day or two.

This can be particularly important for international patients travelling for treatment or for individuals with medical conditions that increase surgical risk.

What are the risks of Gamma Knife treatment for pituitary tumours?

All treatments carry risk, and honest discussion is essential.

With Gamma Knife for pituitary tumours, potential risks include:

• Delayed hormonal deficiency (requiring hormone replacement)
• Rare visual disturbance if the tumour is very close to optic nerves
• Temporary fatigue or headache

The risk of complications is closely linked to tumour size, location and the experience of the treating centre.

Who is the best candidate for Gamma Knife surgery?

Gamma Knife is most suitable for:

• Small to medium-sized adenomas
• Tumours at least a few millimetres away from the optic nerves
• Residual or recurrent tumours after surgery
• Patients who wish to avoid further invasive procedures

It is not usually appropriate when:

• There is acute vision compromise
• The tumour is very large
• Immediate decompression is required

Every case should be discussed in a multidisciplinary setting including neurosurgeons, endocrinologists, radiation oncologists and physicists.

Pituitary tumours are often manageable, and many patients live full, healthy lives after treatment. The key is accessing balanced, expert advice tailored to your specific diagnosis.

Being diagnosed with a brain arteriovenous malformation (AVM) can be unsettling, particularly when symptoms are mild or absent but the potential risks feel serious.

Gamma Knife radiosurgery is one of several arteriovenous malformation treatment options that may be considered, but patients often want to understand how safe and effective it truly is, and whether it is appropriate for their individual situation.

Gamma Knife is not suitable for every AVM, but in carefully selected cases it can offer a non-invasive and well-established treatment approach.

What is a brain AVM and why does it require careful management?

A brain AVM is an abnormal tangle of blood vessels that disrupts normal blood flow between arteries and veins. This can place stress on vessel walls and, in some cases, increase the risk of bleeding in the brain.

AVMs vary widely in size, location and behaviour. Some are discovered after a bleed or seizure, while others are found incidentally during scans for unrelated symptoms.

Because AVMs are not tumours and do not grow in the same way, treatment decisions are often complex and must balance potential benefits against the natural risks of the condition.

What is Gamma Knife radiosurgery and how does it work for AVMs?

Gamma Knife radiosurgery is a non-invasive technique that delivers highly focused radiation to a precisely defined target within the brain. Despite the term “surgery”, no incision is involved.

For AVMs, Gamma Knife works by:

• Targeting the abnormal blood vessels with precision
• Causing gradual thickening and closure of the vessels over time
• Preserving surrounding healthy brain tissue

Unlike surgical removal, the effect is not immediate. Obliteration of the AVM typically occurs gradually over months or years following treatment.

How effective is Gamma Knife for treating AVMs?

Gamma Knife has been used to treat brain AVMs for several decades, with extensive clinical experience supporting its effectiveness in selected patients.

Success is usually measured by complete obliteration of the AVM on follow-up imaging. Rates of obliteration vary depending on factors such as:

• Size of the AVM
• Location within the brain
• Radiation dose delivered
• Patient age and vascular anatomy

Smaller AVMs tend to respond more favourably, while larger or more complex AVMs may require staged treatment or alternative approaches.

When is Gamma Knife recommended for AVM treatment?

Gamma Knife is often considered when:

• The AVM is small to medium in size
• The AVM is located in a deep or surgically difficult area
• Open surgery carries a higher risk of neurological damage
• The patient has had bleeding or seizures related to the AVM
• Other treatment options are considered too high-risk

In some cases, Gamma Knife may be used alongside other treatments, such as embolisation, as part of a carefully planned strategy.

Is Gamma Knife safe for treating AVMs?

Safety is a key consideration in AVM management. Gamma Knife is generally well tolerated and avoids many of the immediate risks associated with open brain surgery.

However, it is important to understand that:

• The AVM remains present during the latency period before obliteration
• There is still a small ongoing risk of bleeding until closure is complete
• Temporary swelling or neurological symptoms can occur in some patients

Careful patient selection, accurate treatment planning and long-term follow-up are essential to managing these risks effectively.

What are the advantages of Gamma Knife compared with other treatments?

For selected patients, Gamma Knife offers several benefits:

• No incision or general anaesthetic
• Usually performed as a single outpatient treatment
• Minimal disruption to daily life
• Suitable for AVMs in deep or sensitive brain regions

These advantages make Gamma Knife an important option for patients who may not be ideal candidates for surgery.

Are there situations where Gamma Knife may not be appropriate?

Gamma Knife may not be suitable for:

• Very large AVMs
• AVMs causing significant mass effect
• Certain complex vascular configurations
• Patients where immediate removal is required due to active bleeding

In such cases, alternative treatments or staged approaches may be recommended following multidisciplinary review.

How is the best treatment option decided?

Deciding how to treat an AVM typically involves a multidisciplinary team including neurosurgeons, neuroradiologists and radiosurgery specialists.

The team considers:

• AVM size, location and angioarchitecture
• Symptoms and bleeding history
• Patient age and overall health
• Personal preferences and lifestyle factors

This collaborative approach ensures that Gamma Knife is offered only when it is likely to provide a meaningful benefit.

Making informed decisions about AVM treatment

Gamma Knife radiosurgery is a well-established and effective option for many patients with brain AVMs, offering a non-invasive route to long-term vascular closure when appropriately selected.

If you have been diagnosed with a brain AVM, or are supporting someone who has, it may help to discuss the full range of treatment options with our specialist Amethyst UK team who are experienced in AVM care.

World Cancer Day is observed every year on 4 February with the aim to raise awareness, inspire action, and increase access to the highest quality of cancer care. The theme for 2025–2027 is “United by Unique.”

This short phrase brings a larger truth into focus: while cancer connects millions of people worldwide, every individual’s experience of the disease is different. Nowhere is this more evident than in the diagnosis and treatment of brain tumours.

A brain tumour is a complex diagnosis, and every person’s experience of it will be different, influenced by many factors including their genetics, medical history, and personal circumstances.

Researchers and clinicians are increasingly united by the need for a more people-centred approach to cancer care, which takes into account not just the diagnosis, but the unique needs and human story of each patient.

When planning a brain tumour treatment pathway, the precision of modern and continually evolving techniques such as Gamma Knife surgery has an increasingly important role to play. Here, we look at why it offers far more than a one-size-fits-all approach.

Why are brain tumours so complex to treat?

Even when two patients are diagnosed with the same type of brain tumour, their situations are rarely identical. Tumours vary in size, shape, growth rate and, critically, location.

A small lesion in one area of the brain may cause significant symptoms, while a larger tumour elsewhere may initially go unnoticed.

Beyond anatomy, each patient brings their own health background into the equation. Age, existing medical conditions, neurological function, previous treatments and overall resilience all influence which treatment options are appropriate.

For some, the priority may be long-term tumour control; for others, preserving cognitive function, independence or quality of life is paramount. This is why modern cancer care is moving towards a more personalised and flexible approach.

How does advanced Gamma Knife technology support personalised brain cancer care?

People-centred cancer care starts with listening to the patient’s symptoms, concerns, and priorities, supported with detailed diagnostic imaging and clinical assessment.

In the context of brain tumours, precision matters. Small differences in tumour position can significantly affect treatment planning. This is particularly crucial when critical structures such as speech, movement, vision or memory centres are involved.

The goal is not simply to treat the tumour, but to do so while minimising disruption to the surrounding healthy brain tissue, and reducing the side effects of the tumour.

Gamma Knife radiosurgery was developed with this level of precision in mind. Using highly focused beams of radiation, it allows clinicians to target tumours with sub-millimetre accuracy, shaping treatment around the unique contours of each patient’s anatomy.

Why brain cancer treatment should adapt to the patient

Traditional brain surgery can be life-saving and essential in many cases. However, it is not always the best or safest option for every patient. Some tumours are located deep within the brain or close to vital structures, making open surgery higher risk.

Others may be small, slow-growing, or recurrent after previous treatment. Gamma Knife radiosurgery offers a non-invasive alternative for selected patients, typically delivered in a single outpatient session.

The procedure involves no incision, no general anaesthetic, and minimal recovery time. For many people, this means less disruption to daily life, reduced hospital stays, and a quicker return to normal activities.

Importantly, this approach supports a more individualised care pathway that takes into account not just the tumour, but the person living with it.

A shared commitment to personalised cancer care

World Cancer Day’s United by Unique theme highlights the importance of recognising individual needs while working collectively to improve outcomes for all.

In practice, this means multidisciplinary teams collaborating closely, neurosurgeons, oncologists, physicists, nurses and support staff, each contributing their expertise to tailor treatment plans.

It also means clear communication, realistic expectations, and ongoing support before, during and after treatment. True people-centred care combines advanced treatment options with empathy, transparency and respect for patient choice.

Looking beyond survival alone

Cancer care is no longer measured solely by survival statistics. Increasingly, it is judged by how well patients are able to live during and after treatment.

Preserving neurological function, maintaining independence and supporting emotional wellbeing are essential outcomes in their own right.

For many patients with brain tumours, Gamma Knife radiosurgery represents an approach that aligns with these priorities. By tailoring treatment to the individual, clinicians can often achieve effective tumour control while minimising side effects and protecting quality of life.

As cancer treatment continues to evolve, personalised approaches will remain central. If you would like to find out more about Amethyst Radiotherapy’s unique brain cancer treatment pathways, please get in touch with our team today.

When someone is diagnosed with a complex brain condition, the treatment journey can feel daunting. Decisions are rarely straightforward and the results are crucial, affecting not only survival, but also cognition, mobility, independence, and quality of life.

In this context, who plans and delivers treatment matters just as much as what treatment is chosen. This is where a multidisciplinary team (MDT) approach plays a critical role.

For conditions treated with advanced techniques such as Gamma Knife radiosurgery, MDT working is widely recognised as a key factor in achieving safer, more effective, and more personalised outcomes.

What is a multidisciplinary team in brain care?

A multidisciplinary team brings together specialists from different clinical disciplines to jointly assess, plan, and deliver patient care.

Rather than decisions being made by a single clinician, the MDT combines multiple expert perspectives to ensure that every aspect of a patient’s condition is considered.

In complex neurological care, an MDT typically includes:

• Neurosurgeons
• Radiation oncologists
• Neuroradiologists
• Medical physicists
• Specialist nurses
• Sometimes neurologists, endocrinologists, or pain specialists, depending on the condition

Each professional contributes unique expertise, allowing the team to balance tumour control, neurological safety, and long-term wellbeing.

Why single-discipline decision-making isn’t enough

Brain conditions such as meningiomas, brain metastases, pituitary tumours, arteriovenous malformations, or trigeminal neuralgia often sit at the intersection of multiple specialties.

A treatment that looks optimal from one perspective may carry hidden risks when viewed from another.

For example:

• A neurosurgeon may assess surgical feasibility.
• A radiation oncologist evaluates radiosurgical precision and dose safety.
• A neuroradiologist ensures imaging interpretation is accurate.
• A physicist confirms that radiation delivery can be executed safely and precisely.

MDT discussions reduce the risk of over-treatment, under-treatment, or avoidable complications, leading to more confident and defensible clinical decisions.

What is the role of an MDT in Gamma Knife surgery?

Gamma Knife radiosurgery is one of the most precise treatment tools in modern medicine. That precision, however, depends on meticulous planning and collaboration.

Before treatment, MDTs jointly:

• Review diagnostic imaging in detail
• Confirm the exact diagnosis and treatment indication
• Decide whether radiosurgery, surgery, monitoring, or a combination is most appropriate
• Agree on dose planning and risk mitigation strategies

This collaborative process ensures that radiosurgery is used only when it is genuinely the best option, and that it is delivered in the safest possible way.

How do MDTs improve safety in Gamma Knife surgery?

Many brain conditions are located close to vital structures such as the optic nerves, brainstem, cranial nerves, or hormonal control centres. Damage to these areas may impact vision, hearing, balance, or endocrine function.

MDT working is particularly important in these cases. Input from multiple specialists helps the team:

• Define safe treatment margins
• Minimise radiation exposure to healthy tissue
• Anticipate and manage potential side effects
• Adjust treatment plans based on individual anatomy

The result is a more refined approach that prioritises function preservation alongside disease control.

Can MDT models improve outcomes in complex brain treatment?

Centres that operate MDT-led care models often manage a high volume of complex cases. This collective experience improves decision-making, particularly for rare or challenging conditions.

MDTs allow clinicians to:

• Learn from past cases and long-term follow-up data
• Apply evidence-based protocols consistently
• Discuss atypical presentations or borderline cases openly
• Align treatment decisions with the latest clinical research

For patients and families, this translates into greater confidence that recommendations are not based on opinion alone, but on shared expertise and established evidence.

How do MDTs provide reassurance for patients and families?

For patients navigating a life-changing diagnosis, MDT-led care provides reassurance and clarity during an uncertain time. Knowing that multiple experts have reviewed the case can reduce anxiety and help patients feel supported rather than rushed into decisions.

Importantly, MDTs also support clearer communication, with a Clinical Nurse Specialist acting as the key point of contact. Treatment recommendations are more likely to be:

• Clearly explained
• Balanced and transparent
• Aligned with the patient’s priorities and values

This patient-first approach is essential when discussing options that may affect long-term neurological health.

How do MDTs support referring clinicians and continuity of care?

Multidisciplinary working is equally valuable for referring clinicians. It provides a trusted framework for collaboration, particularly when managing complex cases that benefit from specialist input.

MDT-led centres often work closely with:

• NHS hospitals
• International healthcare providers
• Local specialists managing ongoing care

This ensures continuity before, during, and after treatment, which is especially important for international patients who may return home following radiosurgery.

A collaborative approach that puts patients first

Multidisciplinary teams are not just a clinical structure; they represent a philosophy of care. By combining expertise, experience, and empathy, MDTs ensure that treatment decisions are made with the whole patient in mind, not just the diagnosis.
