When a loved one suffers a subarachnoid haemorrhage (SAH), it can be life-changing. Families are often faced with a medical emergency they have never heard of, complex hospital treatment, and uncertainty about what lies ahead. At a time like this, it is vital to have clear information, guidance, and compassionate professional support. This article aims to explain what a subarachnoid haemorrhage is, how it is diagnosed and managed, and what to do if you are worried that medical negligence may have played a part. What is a subarachnoid haemorrhage? A subarachnoid haemorrhage (SAH) is a type of stroke caused by bleeding into the space surrounding the brain – the subarachnoid space. This area is filled with cerebrospinal fluid that cushions the brain, and when bleeding occurs there, it creates dangerous pressure and irritation to the brain tissue. The most common cause of a subarachnoid haemorrhage is the rupture of an aneurysm – a weak spot in a blood vessel that balloons out over time and can burst suddenly. However, other causes include head injury, blood clotting disorders, or vascular malformations. Although subarachnoid haemorrhage accounts for a relatively small percentage of all strokes, it tends to affect people at a younger age and can have devastating consequences if not recognised and treated promptly. Subarachnoid haemorrhage symptoms Recognising subarachnoid haemorrhage symptoms quickly can be lifesaving. The hallmark symptom is a sudden, severe headache, often described as “the worst headache of my life.” It can come on instantly, sometimes during physical activity or emotional stress. Other symptoms may include: Neck stiffness and pain Nausea and vomiting Sensitivity to light (photophobia) Blurred or double vision Seizures Sudden confusion or collapse Loss of consciousness Because these symptoms can mimic other, less serious conditions like migraines or viral infections, misdiagnosis can occur. However, early recognition and emergency treatment are vital. Anyone experiencing a sudden, severe headache unlike any other should be taken to hospital immediately. Subarachnoid haemorrhage diagnosis Accurate and timely subarachnoid haemorrhage diagnosis is crucial to give the best possible chance of recovery. In the emergency department, doctors should take a detailed history, focusing on the onset and nature of the headache and any associated symptoms. If a subarachnoid haemorrhage is suspected, the following investigations are typically carried out: CT scan – This is usually the first test. It can detect bleeding around the brain in the majority of cases. Lumbar puncture – If the CT scan is normal but suspicion remains high, a sample of spinal fluid may be tested for signs of blood. CT angiography or MR angiography – These scans help identify the source of bleeding, such as an aneurysm or vascular abnormality. Delays or errors in diagnosis can have devastating consequences. If a subarachnoid haemorrhage is missed, the risk of a second, often fatal, bleed increases dramatically. Management of subarachnoid haemorrhage The management of subarachnoid haemorrhage depends on the cause, severity, and timing of diagnosis. Most patients require care in a specialist neuroscience unit, often in an intensive care setting. Treatment may include: Surgical intervention – to secure the aneurysm and prevent further bleeding. This can be done through: Clipping, where a small metal clip is placed on the neck of the aneurysm, or Endovascular coiling, a minimally invasive procedure where coils are inserted to block off the aneurysm from within the blood vessel. Controlling blood pressure – to prevent re-bleeding or other complications. Medication – such as nimodipine, used to reduce the risk of delayed brain injury caused by vasospasm (narrowing of blood vessels). Monitoring and rehabilitation – ongoing neurological assessments and support from physiotherapists, occupational therapists, and speech and language therapists. Recovery varies greatly. Some people make an excellent recovery, while others experience long-term effects such as memory problems, fatigue, and personality changes. Emotional and practical support for families For families, a subarachnoid haemorrhage can be an overwhelming experience. The sudden nature of the illness, combined with the uncertainty of the outcome, can lead to feelings of shock, anxiety, and helplessness. Hospitals usually have specialist nurses, counsellors, or stroke liaison teams who can provide information and emotional support. Charities such as The Brain & Spine Foundation and The Stroke Association also offer practical resources and connect families with others who have gone through similar experiences. When things go wrong – subarachnoid haemorrhage claims While most healthcare professionals provide excellent and timely care, there are occasions when avoidable errors occur. Delayed or missed subarachnoid haemorrhage diagnosis, failure to act on warning symptoms, or errors in treatment and monitoring can lead to serious injury or death. If you believe that medical mistakes contributed to the harm suffered by you or a loved one, you may wish to explore the possibility of a subarachnoid haemorrhage claim.
