Claiming for a brain aneurysm

Medical negligence whilst uncommon can have a big impact on your life and wellbeing.

A brain aneurysm is often a terrifying diagnosis. But in most cases, care is of an excellent standard and those that are at high risk of rupturing and causing complications are treated. However, there are patients that are affected by misdiagnosis or don’t receive the level of care they should from those responsible, including when the aneurysm ruptures, potentially causing brain damage or death.

We know that at a time when you want to focus on recovery, deciding to take a legal claim forward against those responsible can be scary. But misdiagnosis of brain aneurysm compensation can support you on your road to recovery and help improve your quality of life. Not only can financial compensation alleviate financial concerns that you may have but it can pay for care, equipment, or adaptations that you may now require as a result of complications. A misdiagnosis of brain aneurysm can have serious consequences, leaving those affected feeling vulnerable and unable to trust the healthcare system. A case against those responsible can help patients better understand why they were affected and move on.

We understand how complex the legal system can be to those seeking to make a medical negligence claim. But we’ll be on hand every step of the way. With a brain aneurysm misdiagnosis lawyer working on your behalf, you can rest assured that we’ll build a case that gives you the best possible chance of success and compensation.

The time limit on making a brain aneurysm claim

If you would like to make a medical claim against those responsible for medical negligence you have experienced, there is a time limit. You must take a case forward within three years from the ‘date of knowledge’.

The term ‘date of knowledge’ can be confusing but it simply refers to the point that you first realised a mistake had been made. This could be, for instance, once you’re accurately diagnosed. In complex case it can be difficult to understand exactly how long you have left to take a claim forward. Our expert team can help here. We’ll listen to your experience and use our skills and insights to provide you with a timeframe.

While you do have up to three years to act, we recommend to our clients that they take action as soon as possible. We understand that it can be a daunting prospect after you’ve been misdiagnosed with a brain aneurysm but we’ll take the hassle out of your hands. From the very beginning of the process, we’ll work on you behalf to build a case against those responsible and this can often be easier the quicker a case is started, strengthening your chance of success.

The brain aneurysm claims process

Step 1 - Obtaining your medical records

We ask you to sign forms of authority so that we can obtain your medical records from your GP and any hospitals that have treated you.

Step 2 - Providing your statement of what happened

As the medical experts we instruct need to know what happened during your treatment, we work with you to draft a detailed, accurate statement in your own words.

Step 3 - Minimising your loss

You are responsible for minimising the losses you have incurred as a result of the alleged medical negligence, so you need to attend any available treatments that could aid your recovery.  You may also need to return to work as soon as it’s safe to do so.

Step 4 - Establishing that a breach of duty occurred

You must prove that the treatment you received fell below the standard expected of a reasonably competent and skilful medical specialist of the type who treated you and that, as a result, you suffered a loss or injury.  To do this, we obtain independent medical evidence from an expert in the appropriate area of medicine.

Step 5 - Establishing the effect of the breach of duty

We have to establish whether the sub-standard treatment you received is likely to have led to your injury or loss. As this can be difficult to establish, you may need to see one or more medical experts who will assess your current condition and what the future holds for you.

Step 6 - Calculating the value of your claim

The value of your claim comprises:

  • general damages for the pain, suffering and impact of the negligence on your daily life both now and in the future
  • actual financial losses such as loss of earnings, cost of care, medical and travel expenses.

Step 7 - Proving your loss

You need to keep all original financial documents safe as these will be needed when we prepare your case to go to Court. These documents include accounts, payslips, and receipts for expenses and medical treatments.

Step 8 - Preparing your case for Court

Although only a small number of cases proceed to a trial, we prepare every case for this eventuality.

Step 9 - Attending the trial in Court

The trial takes place before a Circuit or High Court judge who will make a decision based on the evidence we have prepared.

Step 10 - Awarding your compensation claim

If you win your case, the amount of compensation will be decided by negotiation with the defendant or, if your case goes to trial, by the judge. The defendant will usually be ordered to pay us the costs we have incurred in preparing your case. We will also agree a date by which your compensation will be paid to us so that we can pay your compensation as quickly as possible.

Frequently asked questions

Can I claim for misdiagnosed brain aneurysm?

If you’ve been affected by medical negligence and those responsible for your care let you down, you may have a brain aneurysm misdiagnosis lawsuit you can take forward.

Whether the issues arose due to GP misdiagnosis of a brain aneurysm or test results were read inaccurately we could help you. A ruptured brain aneurysm is a serious condition that can lead to long-term complications and even prove fatal if not treated swiftly. As a result, it’s vital that those responsible for you care act urgently. You may have a claim you can take forward if you experienced the following:

  • A doctor missing the initial warning signs of a brain aneurysm
  • Symptoms of a brain aneurysm not being followed up
  • An existing brain aneurysm not being monitored as frequently as it should have been
  • The signs of a ruptured brain aneurysm not being treated as an emergency
  • Treatment for a high risk brain aneurysm or a ruptured aneurysm being unnecessarily delayed

If you believe you have a claim, speaking to our team of expert brain aneurysm misdiagnosis lawyers can help you understand the process. We’ll listen to your case and offer you professional advice that you know you can rely on.

Can I claim for misdiagnosed brain aneurysm on behalf of a loved one?

Yes, it is possible to claim for medical negligence on behalf of a loved one. For instance, if your child or partner had a brain aneurysm that was misdiagnosed leading to complications or death, you may be able to claim brain aneurysm misdiagnosis compensation. 

If you’re making a claim that has affected someone else the same procedures will still need to be followed as in typical brain aneurysms misdiagnosis compensation claims. This includes being subject to a three-year time limit and demonstrating that there were opportunities for medical professionals to achieve an accurate diagnosis.

How much compensation will I get?

How much compensation each person making a medical claim will receive varies taking a wide range of factors into account, such as brain aneurysm negligence complications and the affect it has had on quality of life.

When you contact Your Legal Friend, we’ll take the time to listen to your experiences and understand how you have been affected. Taking this into consideration we will give your claim a value that accurately reflects the brain aneurysm malpractice that you experienced. Without learning more about your case, we can’t say how much compensation you could receive if successful but every year the NHS pays out millions to those affected by medical negligence.

How long do I have to make a claim?

Those affected by medical negligence that would like to make brain aneurism claims for the affect it has had, must make a claim against those responsible within three years.

The time limit on any medical claim starts from the ‘date of knowledge’. The term refers to the point that you first realised a mistake had been made in your level of care. This could be when you’re first accurately diagnosed or it could even occur after this point. Brain aneurysm misdiagnosis claims can be complex and if you’re unsure how long you have left to make a claim, we can help you. Using our skills and knowledge of medical negligence law and previous cases, we will help you pinpoint your ‘date of knowledge’.

You can act at any point during these three years. However, we recommend that you start your brain aneurysm lawsuit as soon as possible. This means you’ll be able to better recall your experiences, ensuing your witness statement is as detailed as possible. We’ll also request other pieces of documents to support your case, such as your medical records, and these may be easier to obtain closer to your experiences.

What is a brain aneurysm?

An aneurysm is a bulge in a blood vessel caused by a weakness in the wall of the vessel. Aneurysms can develop in any blood vessel in the body but one of the most common places for them to occur is in the brain, also known as an intracranial or cerebral aneurysm.

Brain aneurysms typically don’t cause any symptoms unless they rupture but this can have serious complications, including brain damage. Around 60% of those that have subarachnoid haemorrhage, where bleeding can cause extensive brain damage, will die within two weeks and those that survive have a high risk of being left with severe brain damage or a disability.

As a result of the potential risks of the condition, a late brain aneurysm negligence diagnosis can have a serious impact on prognosis and the health of the patient concerned.

What causes a brain aneurysm?

The brain requires a large supply of blood that is delivered through four main blood vessels that then divide into smaller vessels. A brain aneurysm occurs when the wall of these vessels weakens, allowing a bulge to occur.

In many cases, it’s not possible to pinpoint exactly why a brain aneurysm has occurred but there are associated risk factors that increase a person’s likelihood of developing the condition. Common risk factors are:

  • Smoking – Research indicates that the majority of people that are diagnosed with a brain aneurysm smoke or have done so in the past.
  • High blood pressure – A high blood pressure can increase the pressure that is placed on the walls of a blood vessel, increasing the likelihood of an aneurysm occurring.
  • Family history – Having a parent, sibling, or other first degree relative with a history of a brain aneurysm can indicate that you’re more likely to suffer too. However, only around 2% of people with a family history of a ruptured brain aneurysm experience it themselves.
  • Age – Most people diagnosed with a brain aneurysm are aged over 40 and the risk increases as you age.
  • Sex – Women are more likely to develop a brain aneurysm than men.

Other risk factors linked to brain aneurysms include:

  • Pre-existing weakness in the blood vessels
  • Severe head injury
  • Cocaine abuse
  • Autosomal dominant polycystic kidney disease
  • Body tissue disorders
  • Coarctation of the aorta

What are the symptoms of a brain aneurysm?

In the majority of cases, an unruptured brain aneurysm doesn’t cause any symptoms, meaning it is often left undiagnosed. Where the aneurysm is large or presses against tissues or nerves within the brain, symptoms may include:

  • Visual disturbances, including double vision and loss of vision
  • Pain above or around the eyes
  • Numbness or weakness on one side of the face
  • Difficulty speaking
  • Headaches
  • Loss of balance
  • Difficulty concentrating or problems with short-term memory.

Where a brain aneurysm has ruptured the most common symptom, is sudden, blinding pain. Other signs of a ruptured brain aneurysm include:

  • Feeling or being sick
  • Stiff neck or neck pain
  • Sensitivity to light
  • Blurred or double vision
  • Sudden confusion
  • Loss of consciousness
  • Seizures
  • Weakness on one side of the body or in limbs

A ruptured brain aneurysm is a serious, life threatening condition and a delayed diagnosis of brain aneurysm can have serious consequences. As a result anyone experiencing the symptoms should treat it as a medical emergency and call 999.

How is a brain aneurysm diagnosed?

How a brain aneurysm is successfully diagnosed will often depend on whether it has ruptured or not.

MRI scan – A MRI scan uses magnetic fields and radio waves to produce detailed images of your brain. An MRI scan is often used to identify aneurysms that haven’t ruptured.

CT scan – If a bran aneurysm has ruptured causing bleeding in the brain, a CT scan is the preferred method of achieving a diagnosis.

Lumbar puncture – A CT scan isn’t always accurate in identifying a ruptured brain aneurysm. If your symptoms suggest that an aneurysm is to blame but the results of a CT scan don’t confirm this, a lumbar puncture may be ordered. This is where a sample of the fluid that surrounds the brain and spine is taken to test for signs of bleeding.

If a CT scan, MRI scan, or lumbar puncture suggest that either a ruptured or unruptured brain aneurysm is present, an angiogram or arteriogram will be carried out. This provides medical professionals with additional information to plan your treatment.

A quick and accurate diagnosis is vital for delivering effective treatment for a brain aneurysm that could save a person’s life or minimise the long-term effects. If you’ve experienced missed brain aneurysm diagnosis, you may be able to make a compensation claim, reflecting the seriousness of the medical negligence you experienced and its impact on your health.

How is a brain aneurysm treated?

Brain aneurysms can be treated with surgery. However, as the surgery itself has a risk of complications, including brain damage or stoke, it is only recommended if there’s a high risk that the aneurysm will rupture. A surgical team will take a range of factors into consideration when deciding whether to recommend surgery, including the size and location of the aneurysm.

As preventive surgery, there are two techniques that may be recommend to stop the blood flowing into the aneurysm and reduce the risk of it rupturing – neurosurgical clipping and endovascular coiling. Which option is recommended will be depend on your own personal circumstances.

Where a brain aneurysm has ruptured, emergency treatment will been to be given to reduce the risk of the blood supply to the brain becoming severely disrupted. Emergency treatment aims to reduce the risk of long-term side effects, such as brain damage.

If you or a loved one has experienced a wrong brain aneurysm diagnosis, which meant that vital surgery was delayed, you may be able to make a failure to diagnose claim against those that are responsible. You should be able to rely on those in charge of your care to take the necessary steps to first diagnose and then treat a brain aneurysm.

How can brain aneurysm be misdiagnosed?

There are several ways that brain aneurysms can be misdiagnosed, severely affecting the outcome of the condition.

For instance a doctor misdiagnosed brain aneurysm can occur if you visit your GP with the signs of an unruptured aneurysm but they fail to recognise the signs. Having the condition diagnosed before it ruptures can improve a patient’s chance of survival and significantly reduce the effects of lifelong complications. Even if it’s recommend that treatment isn’t conducted, a quick diagnosis can allow for careful monitoring.

In some misdiagnosed brain aneurysm cases, the delay in achieving an accurate diagnosis is down to the test results being read incorrectly or not followed up. In some cases, the common tests for a reputed brain aneurysm do not show the conditions. As a result, doctors should order a lumbar puncture if symptoms indicate they could be linked to an aneurysm. Where this doesn’t occur it can lead to a significant delay in brain aneurysm diagnosis, which can, in turn, increase the risk of complications, including significant brain damage.

A delay in diagnosis of brain aneurysm due to medical negligence could be the grounds for a compensation claim, reflecting the damage that has been caused.

What conditions can a brain aneurysm be misdiagnosed as?

Despite a generally excellent level of care in the UK, it is still possible for cases of misdiagnosis of brain aneurysm to occur.

Case studies of misdiagnosis or brain aneurysm show that the condition has been mistaken for:

  • Migraines
  • Cluster headache
  • Eye pain

How often is brain aneurysm misdiagnosed?

There aren’t any official brain aneurysm misdiagnosis statistics for the UK to demonstrate how widespread the problem is but there have been instances of patients with a brain aneurysm suffering due to medical negligence. In brain aneurysm misdiagnosis cases it may be possible to make a claim for compensation, reflecting how those involved have suffered.

Previous research on the NHS has indicated that as many as 1 in 6 patients are initially misdiagnosed across all conditions, indicating that there could be many misdiagnosed brain aneurysm stories.

What are the statistics of brain aneurysms?

It’s difficult for experts to estimate the number of people affected by brain aneurysms because they often cause no symptoms and pass undetected. According to the NHS, estimates range from 1 in 20 people experiencing a brain aneurysm to just 1 in 100.

However, the number of brain aneurysms that rupture is very small. Each year just 1 in 12,500 people will have a ruptured brain anerusym.
