The recent announcement that the Queen’s Medical Centre (QMC) in Nottingham has launched a 24/7 mechanical thrombectomy service marks a significant advancement in acute stroke care and represents a critical benchmark for the UK healthcare system.

Mechanical thrombectomy, a highly effective procedure for large vessel occlusion (LVO) ischemic strokes, has revolutionised treatment by physically removing the blood clot blocking blood flow to the brain, dramatically improving functional outcomes and reducing long-term disability. However, the efficacy of this time-sensitive procedure is directly tied to its availability, and the historic limitations of service hours in many UK hospitals have meant that stroke patients presenting ‘out-of-hours’ have not always been able to access this life-changing treatment.

Nottingham’s initiative directly addresses this inequity, ensuring that every severe stroke patient in their catchment area now has the same chance at a positive outcome, regardless of when their medical emergency occurs.

The establishment of a round-the-clock service requires considerable investment in specialist infrastructure, staffing, and coordinated care pathways. It mandates a robust multidisciplinary team, including interventional neurologists or radiologists, neuroanaesthetists and specialist nurses, available at all times.

By committing these resources, Nottingham’s QMC has demonstrated a profound understanding of the “time is brain” principle. For every minute of a large vessel occlusion, millions of neurons are lost, underscoring the urgency of reperfusion. Providing 24/7 access eliminates the critical delays that previously led to preventable disability and, in some cases, death. This move aligns with and advances the recommendations of national stroke guidelines, which consistently advocate for expanded access to thrombectomy services.

While Nottingham’s accomplishment is commendable, it also highlights a persistent disparity in access to advanced stroke care across the UK. For true health equity, this model of 24/7 mechanical thrombectomy provision must be replicated in all hospitals capable of treating stroke survivors. The postcode lottery of care, where a patient’s outcome is determined by geographical location and the time of their stroke, is medically and ethically indefensible.

For example, the shocking case of Graham McGowan highlights a critical failing within Scotland’s stroke services, demanding urgent intervention by the NHS and government. Doctors carried out a brain scan which revealed a blood clot and they advised he should be treated with a thrombectomy; a procedure to remove blood clots in a large artery. But, ARI’s closest specialist thrombectomy hub, in Ninewells Hospital in Dundee, only offers the procedure from Monday to Friday, leaving Graham, a fit and active 53-year-old, with severe and preventable disability simply because his stroke occurred outside of ‘office hours’.

Tackling this failure probably requires a multi-pronged approach: immediate investment to provide a genuine 24/7 national thrombectomy service with expanded hub hours. National bodies and hospital trusts across the UK should leverage the evidence from successful centres like QMC to develop actionable strategies for commissioning and implementing their own 24/7 services.

This would not only save more lives and reduce the national burden of long-term stroke-related disability but would also align the UK’s stroke care provision with the highest international standards. The commitment shown by Nottingham is a powerful example for others to follow, demonstrating that with strategic planning and investment, equitable access to best-practice stroke treatment is an achievable goal.

Artificial Intelligence may have many downsides, but that’s certainly not the case in stroke treatment: in England, it has tripled the proportion of stroke patients who fully recover. Nearly half of stroke patients now recover to the point of functional independence, up from 16 percent.

This AI tech, which aids in the rapid analysis of brain scans, has significantly accelerated the diagnosis and treatment pathway, demonstrating how digital innovation can profoundly impact clinical outcomes. The key to this success lies in expediting the time-critical decisions necessary to administer reperfusion therapies like thrombectomy or thrombolysis.

The picture above shows on the left of each screen what 90% of doctors see using CT scans, versus the right hand side screen which shows the new technology, which identifies the problem areas automatically using the ASPECTS score card method,

One of the pivotal studies cited by NHS England involved the Brainomix e-Stroke system. This AI software was used in pilot programs across five stroke networks and has now been deployed to all 107 stroke centres in England.

Analysis of its impact showed a dramatic reduction in the time from hospital arrival to treatment, from an average of 140 minutes down to just 79 minutes. This crucial time-saving, which is critical since a stroke patient can lose millions of brain cells every minute, led to a proportional increase in positive outcomes. The proportion of patients who recovered with little or no disability soared from 16% to 48%, a threefold improvement.

The AI’s ability to provide rapid, real-time interpretation of brain scans allows specialist stroke units to make faster, more confident decisions regarding the most appropriate treatment, ultimately providing more patients with a better chance of recovering their independence.

In practice, the AI software rapidly processes CT brain scans and produces detailed reports for clinicians. These reports, including perfusion maps that highlight areas of reduced blood flow, are instantly shared across the clinical team via a secure platform. This streamlined communication and immediate insight allow for swift and coordinated action, reducing the critical time between diagnosis and the start of treatment.

The technology’s success has not only been evidenced in official reports but also validated by patient testimonials, such as that of Mr. Shawn Theoff, a retired postman from Canterbury who experienced a rapid recovery from a stroke thanks to the use of AI-enhanced diagnosis and treatment at Kent and Canterbury Hospital. He was taken to the hospital after experiencing stroke symptoms, where AI-powered decision support tools helped doctors quickly diagnose his condition and administer medication, leading to a swift recovery that saw him walking again within a few weeks. 

In-hospital strokes represent a critical and often-overlooked challenge in patient safety, with delays in detection leading to devastating outcomes. The old adage ‘time is brain’ is never more relevant than when a patient, already under medical care, suffers a new neurological event that can be easily missed amidst the complexities of a hospital environment.

This is where innovative technology like the Neuralert wristband offers a compelling and potentially game-changing solution. Recently developed at the University of Pennsylvania Health System, this wearable device continuously monitors for subtle, asymmetric arm movements (a key indicator of stroke) and automatically alerts medical staff within minutes. Unlike manual checks, which can be infrequent and prone to human error, this 24/7 automated surveillance dramatically cuts the time to diagnosis, leading to faster treatment initiation, improved patient outcomes, and reduced healthcare costs.

While the potential of Neuralert is clear, the NHS hasn’t adopted such pioneering technology. The NHS is already integrating AI for stroke detection, primarily through AI-powered software that analyses brain scans to speed up treatment decisions. These systems have, so far, proven effective in accelerating the stroke pathway from scan to treatment, but they are most impactful after a stroke has been clinically suspected and a scan requested.

Neuralert, however, addresses the crucial step before this, offering a proactive, continuous monitoring solution to bridge the gap in surveillance for high-risk, non-ambulatory patients who are difficult to monitor manually.

Despite the clear clinical and economic rationale, Neuralert hasn’t been formally planned for incorporation into NHS stroke wards, probably because the NHS adoption pathway for new medical technology is robust but slow, requiring extensive trials, regulatory approvals, and evidence of cost-effectiveness.

Therefore, while Neuralert’s utility is undeniable, its journey from a breakthrough concept to a standard feature of UK NHS stroke care will depend on successful clinical trials within the NHS, robust cost-effectiveness data, and a clear pathway for national implementation.

M (a well-known HIV drug) is an FDA-approved HIV medication, a C-C chemokine receptor type 5 (CCR5) antagonist, now being investigated for its potential to improve recovery in stroke patients. A body of preclinical research and observational studies suggests that blocking the CCR5 receptor can augment neuroplasticity, potentially enhancing functional and cognitive outcomes following a stroke. This avenue of research is particularly hopeful as it explores repurposing an existing drug with a known safety profile for a new and critical application.

Several clinical trials are currently exploring the potential of M in stroke recovery. For instance, the Canadian M Randomised Controlled Trial to Augment Rehabilitation Outcomes After Stroke (CAMAROS) is a Phase II, placebo-controlled trial evaluating the efficacy of combining M with exercise rehabilitation. The trial involves 120 participants and measures motor and cognitive function. This approach is based on animal studies showing that blocking CCR5 can enhance motor recovery and improve learning deficits after a brain injury.

Another Phase II trial focuses on preventing post-stroke cognitive impairment (PSCI) and progression to vascular dementia. Additionally, an open-label, proof-of-concept study has demonstrated the potential for M to improve post-stroke depression (PSD) symptoms.

The rationale behind these trials is compelling and grounded in basic science. A naturally occurring mutation that inactivates the CCR5 receptor (CCR5-$\Delta$32) is associated with better recovery outcomes in stroke survivors. This observation suggests that CCR5 activity can impede recovery, and therefore, blocking it with a drug like M could be therapeutically beneficial.

By inhibiting CCR5, the drug appears to promote synaptic plasticity, allowing the brain to better reorganise and repair itself after an injury. The current clinical trials, by rigorously testing these hypotheses, offer significant hope that M could one day become a valuable tool in the stroke recovery arsenal. If successful, this research could lead to the first pharmacological treatment specifically designed to enhance recovery for stroke patients..

Nature still hides numerous ingenious solutions. DMT, or dimethyltryptamine is a natural psychoactive molecule found in many plants and mammals. According to an article published in Science Advances, DMT was found to reduce the harmful effects of stroke in animal models and cell culture experiments. The study was authored by Hungarianresearchers from the HUN-REN BRC Institute of Biophysics and Semmelweis University Heart and Vascular Centre.

DMT is also present in the human brain, and it is currently undergoing clinical trials to aid recovery of brain function after stroke. However, its exact mechanism of action had not been fully understood until now.

According to the authors of the study, the research teams found that DMT significantly reduced infarct volume and edema formation in a rat stroke model. In both animal experiments and cell culture models, DMT treatment restored the structure and function of the damaged blood-brain barrier and improved the function of astroglial cells. Furthermore, the psychoactive compound inhibited the production of inflammatory cytokines in brain endothelial cells and peripheral immune cells, while reduced the activation of brain microglia cells through Sigma-1 receptors.

The therapeutic options currently available for stroke are very limited. The dual action of DMT, protecting the blood-brain barrier while reducing brain inflammation, offers a novel, complex approach that could complement existing treatments.

Since current stroke therapies do not always result in full recovery, a DMT-based treatment may represent a promising new alternative, mainly in combination with existing methods. The recent findings from researchers in Szeged and Budapest support the development of a therapy that goes beyond the limitations of conventional stroke treatment. Clinical trials have already begun abroad, and investigation on the long-term effects of DMT are currently ongoing, but there is still a long way to go before it reaches everyday medicine.

For stroke survivors with severe upper limb paralysis, the challenge of engaging in rehabilitation is profound. Conventional electrical stimulation (ES) methods that rely on detecting residual voluntary muscle activity, such as electromyography (EMG)-triggered systems, are often unsuitable for these patients. However, a manual ES technique known as finger-equipped electrode electrical stimulation (FEE-ES) has shown promising potential. This approach allows therapists to directly and precisely control the delivery of electrical pulses, effectively reintroducing the element of patient intention into the therapeutic process.

FEE-ES is a therapist-controlled functional electrical stimulation method where the clinician wears an electrode on a finger, akin to a thimble or finger cap. This allows the therapist to manually apply and release the electrical stimulus to the patient’s skin with precise timing. By placing conventional self-adhesive electrodes on the affected limb, the therapist uses the finger-electrode to deliver the electrical pulses. This allows the therapist to precisely synchronise the electrical stimulation with the patient’s motor intention, even in cases where no voluntary muscle movement or detectable EMG signal is present. This feature engages the patient’s brain in the motor relearning process from the very beginning of rehabilitation.

Early clinical studies have shown that FEE-ES can be feasible, safe, and potentially effective for severe upper limb paresis. In a 2012 study on chronic stroke patients, those receiving FEE-ES showed greater improvement in upper extremity function compared to a control group. A  retrospective case series published this year demonstrated that FEE-ES in the acute phase of stroke was feasible, well-tolerated and associated with significant improvements in upper limb motor function in patients with severe paresis.

The synchronisation of electrical stimulation with the patient’s motor intent is believed to promote neuroplasticity, strengthening the neural pathways and encouraging long-term functional recovery. A primary advantage of FEE-ES is its ability to bridge the gap between intent and movement, a critical aspect of recovery that is often inaccessible to severely impaired stroke survivors using conventional ES systems.

FEE-ES is a clinical technique, not a standalone commercial product available for individual purchase in the UK. The implementation of FEE-ES depends on a qualified physiotherapist or occupational therapist using standard electrical stimulation equipment in a controlled, clinical setting. Therefore, its cost is integrated into the therapy sessions themselves, which vary depending on clinical setting, location, and coverage by the NHS or private insurance. Unlike an off-the-shelf device, FEE-ES is a specialised treatment modality that requires skilled professional application.

For many stroke survivors, regaining the use of their arm and hand is a significant challenge on the road to recovery. Intensive, repetitive and personalised therapy is key, but can be difficult to access consistently. Thecon Technology (HK) Limited, founded by researchers from The Hong Kong Polytechnic University (PolyU), has developed an innovative solution to this problem: the Mobilexo Arm. This wearable hybrid system combines robotics and functional electrical stimulation (FES) to accelerate and assist upper limb rehab.

The Mobilexo Arm is a portable, three-in-one rehab instrument for the paretic upper limb, designed to be used both in clinical settings and by patients at home, Unlike older FES devices with static patterns, the Mobilexo Arm uses electromyography (EMG) to detect residual electrical signals in the user’s muscles. This allows patients to control the device with their own intent, strengthening the brain’s feedback loop and encouraging neuroplasticity. It incorporates hybrid soft, inflatable components that provide mechanical assistance to the elbow, wrist and fingers. This offers a more natural and comfortable alternative to the heavy, rigid robotic arms often found in clinics.

The device provides targeted Neuromuscular Electrical Stimulation (NMES) to activate and strengthen muscles, improving coordination and sensory awareness in the affected limb. An accompanying mobile app allows patients and therapists to monitor progress remotely, track rehabilitation data in real-time, and access a variety of gamified exercises, making training more engaging and effective.

As a cutting-edge medical device, the Mobilexo Arm is not currently available for direct purchase by individuals in the UK. Thecon Technology’s current business model focuses on partnerships with hospitals and clinics. The commercialisation path for such devices typically involves extensive regulatory approvals, so its availability in the UK market would require passing these stringent tests first.

While a specific price for the UK has not been announced, the Mobilexo Arm Pro version is listed at a substantial cost in other regions. However, reports have indicated that the company is also working on a cheaper, home-based version for direct purchase by patients. For now, interested patients in the UK would need to inquire with their local stroke rehabilitation centres or explore participation in clinical trials if they become available.

The Mobilexo Arm’s main advantage lies in its hybrid design and EMG-driven control. By combining the strengths of FES and robotics into one wearable device, it offers a more sophisticated, responsive, and comfortable therapy experience.

The active participation required from the patient, guided by their own muscle signals, is far more effective at promoting neuroplasticity and functional recovery than passive, pre-set stimulation. The portability and engaging app-based exercises also make it easier for survivors to perform the frequent, high-intensity training crucial for regaining upper limb function, extending their rehabilitation beyond the clinical setting.

Can eating more fibre really help prevent a stroke? The evidence suggests it can. New evidence from a meta-analysis published in the American Heart Association journal Stroke further solidifies this link. The findings offer a simple, powerful message: a diet richer in fibre is a diet that better protects your brain.

Dietary fibre, the part of plant foods your body cannot digest, has long been known for its digestive health benefits. However, its influence extends far beyond the gut, impacting crucial cardiovascular risk factors such as blood pressure and cholesterol. A high fibre diet may also contribute to better weight management by promoting a feeling of fullness, which in turn benefits overall cardiovascular health. The new meta-analysis reinforces this, revealing that for every seven-gram increase in daily fibre intake, there was a seven percent reduction in the risk of first-time stroke.

The implication of this research is particularly encouraging because a seven-gram increase is a small, achievable change for most people. It does not require a complete overhaul of your eating habits. This can be as straightforward as swapping white bread for whole grain, adding an extra serving of vegetables or a piece of fruit to your meals, or incorporating legumes like beans and lentils into your diet.

The connection between high fibre intake and a lower stroke risk likely involves several mechanisms. Fibre can help lower blood pressure and ‘bad’ LDL cholesterol, two major risk factors for stroke. Certain types of soluble fibre can form a gel-like substance in the digestive system that slows the absorption of cholesterol and sugar into the bloodstream. Furthermore, fibre helps regulate blood sugar and can support a healthy weight, both of which are important for stroke prevention.

For people looking to reduce their stroke risk, increasing dietary fibre is a practical and accessible step. This research confirms that making small, consistent choices can have a meaningful impact on your long-term health. By focusing on whole-grains, fruits and vegetables, you are not just nourishing your body but also actively working to safeguard your brain.

While functional electrical stimulation (FES) has been a valuable tool in stroke rehab for decades now, advancements in tech are opening doors to more sophisticated and effective therapies. One such innovation is NeuroSkin from Kurage, an AI-powered neuroprosthesis designed to help stroke survivors regain their walking ability and independence.

NeuroSkin is a wearable FES system that integrates smart textile technology with artificial intelligence. Instead of manually applying electrodes, stroke survivors wear specialised garments, such as trousers, which have embedded dry electrodes and sensors. These sensors continuously monitor the user’s gait in real time. This data is then analysed by an AI processing unit, typically housed in a vest worn alongside the garment.

Based on its analysis of the individual’s movement patterns, the AI precisely times and delivers electrical stimulation to the specific muscle groups in the affected leg that need assistance. This helps to activate and strengthen those muscles, facilitating a more natural and symmetrical walking pattern.

The core benefit of NeuroSkin lies in its ability to provide personalised, real-time assistance during walking. Unlike traditional FES systems that often rely on pre-set stimulation patterns, NeuroSkin’s AI adapts to the individual’s unique gait, adjusting stimulation timing and intensity on the fly. This dynamic approach aims to encourage neuroplasticity and more effectively re-establish the connection between the brain’s intention to move and the actual muscle response.

In a retrospective multicenter feasibility study, stroke patients using NeuroSkin showed promising results, including statistically significant improvements in walking speed, endurance, balance and ambulation level. These improvements exceeded clinically meaningful thresholds, suggesting a substantial positive impact on the patient’s quality of life. The system’s excellent usability, rated highly by therapists in the study, further supports its potential for integration into routine rehabilitation.

As of late 2023, NeuroSkin is primarily accessible through specialised rehabilitation centres and clinical trials rather than being available for direct purchase by individuals. Access in the UK is typically through a leasing arrangement with clinics, with an estimated cost of around £5,000 per month. This cost usually includes the use of the device and associated therapy sessions under clinical

The integration of AI and wearable technology in FES, as exemplified by NeuroSkin, offers a significant advantage over conventional FES. By automating and personalising the stimulation process, it addresses key limitations of older FES devices, such as the need for manual electrode placement and parameter tuning. This allows therapists to focus more on guiding the rehabilitation process and supporting the patient, while the technology handles the intricate details of muscle stimulation.

The wearable nature of the system also paves the way for more intensive, home-based therapy, potentially maximising a stroke survivor’s recovery potential by allowing for consistent, high-quality training beyond the confines of the clinic. In essence, the point is to make stroke rehab more targeted, efficient and ultimately more effective in helping survivors regain crucial motor functions.

A recent meta-analysis which has just been published in the journal Neurology. has brought to light a fascinating association between blood type and the risk of early-onset stroke… a condition affecting individuals under the age of 60. While much is known about the risk factors for stroke in older adults, the causes in younger populations are less understood, making this new insight a promising step forward in preventive medicine.

The study, which compiled data from 48 genetic studies involving nearly 17,000 stroke patients and over 600,000 healthy controls, revealed that individuals with the A1 subgroup of blood type A have a 16% higher risk of experiencing an early-onset stroke. This finding was particularly pronounced in the younger adult group, suggesting that genetic factors related to blood type may play a more significant role in early-onset stroke compared to strokes that occur later in life.

Conversely, the research offered some reassuring news for those with blood type O; the meta-analysis found that individuals with blood type O have a slightly lower risk of stroke. Researchers hypothesise that this may be due to blood type O having lower levels of clotting factors, like von Willebrand factor and factor VIII, which could provide a protective effect against unwanted blood clots.

It is crucial to interpret these findings with a degree of caution. While the link is statistically significant, the increased risk is modest, and individuals with type A blood should not be alarmed. This is not a deterministic finding, and lifestyle factors remain the dominant force in overall stroke risk. Modifiable risk factors, such as managing blood pressure, maintaining a healthy weight, exercising regularly and avoiding smoking, have a far greater impact on your risk profile.

The biological mechanisms behind this association are still under investigation. Researchers speculate that differences in blood-clotting factors, platelets and other circulating proteins related to blood type might be at play. This new piece of the puzzle, however, opens new avenues for research into the unique pathology of early-onset stroke, a condition that deserves more scientific attention.
