Two more named in Players' dementia action

The legal action against rugby union’s authorities took a decisive step forward on Thursday when the firm representing nine players diagnosed with long-term brain injuries sent pre-action letters of claim to World Rugby, the Rugby Football Union and the Welsh Rugby Union. Rylands Law also revealed the identities of two more of the nine players involved in the test cases alongside Steve ThompsonAlix Popham and Michael Lipman. They are the former Wales under-20 centre Adam Hughes and the former England under-21 back-row Neil Spence.

The development comes as the former England captain Dylan Hartley spoke out about the lack of teaching in rugby around the risk of dementia. “From when I started until last week, I didn’t know dementia was a potential outcome for any rugby player,” Hartley said on RugbyPass’ Offload podcast. “That wasn’t educated or taught to us.” Hartley admitted he is having his “own problems” with concussion in retirement, but said he does not want to reveal more about them.

Hughes, 30, is the youngest player involved in the action so far. He has been diagnosed with “having brain injuries and post-concussion symptoms”, and has been told he is on a “similar medical trajectory” to Popham, Lipman, Thompson and Spence, who have all been diagnosed with early-onset dementia and probable chronic traumatic encephalopathy. Hughes played for the Dragons, Bristol and Exeter between 2010-18, and his experience throws doubt on the argument that the game has become significantly safer in the past decade.

Hughes was forced to retire at the age of 28 after a particularly severe concussion and is now working as a financial adviser. “It was just one head knock too many. I was finding it more and more difficult to recover from each and every bang to the head,” he said. He reports being knocked out eight times in his career. “At first it was the bigger concussions where I was completely knocked out that took me ages to recover from then over the time even the smaller ones started to have an impact. For the sake of my health, I had to bring it to a halt.”

One of Hughes’s former coaches, Rob Baxter at Exeter, said last week the game’s approach to head injuries has improved so much in the years since Thompson, Lipman and Popham retired that “there’s almost very little value in trying to compare the two”. Hughes, who played for the Chiefs in 2014-15, told a different story. “For me, I think the biggest issue around concussions was attitude. It was often treated like a weakness if you don’t dust yourself down and carry on.”

He added that “the game still has a very long way to go in terms of education about concussion”.

Four more players involved in the test cases have decided to remain anonymous. Rylands Law is already representing around 100 former rugby players and said 30 more have been in contact since the involvement of Thompson, Popham and Lipman was revealed by the Guardian last week.

In a statement World Rugby, the RFU and the WRU said: “We have been deeply saddened to hear the brave personal accounts from former players. Rugby is a contact sport and while there is an element of risk to playing any sport, rugby takes player welfare extremely seriously and it continues to be our number one priority. As a result of scientific knowledge improving, rugby has developed its approach to concussion surveillance, education, management and prevention across the whole game.

“We have implemented coach, referee and player education and best-practice protocols across the game and rugby’s approach to head injury assessments and concussion protocols has been recognised and led to many other team sports accepting our guidance. We will continue to use medical evidence and research to keep evolving our approach.”

Sir Bill Beaumont, the chairman of World Rugby, added: “As a player who retired on medical advice in the early 1980s, I care deeply about the welfare of all players. As an administrator, I will do all I can to maintain the confidence and wellbeing of those who play the game.”

The pre-action letters of claim set out the broad allegations upon which the cases are based. They state the governing bodies had a duty “to take such steps and to devise and implement such rules and regulations as were required in order to remove, reduce or minimise the risks of permanent brain damage as a consequence of the known and foreseeable risk of concussive and sub-concussive injuries”.

They also allege the risks of concussions and sub-concussive injuries were “known and foreseeable”, listing 24 failures on the part of World Rugby, RFU and WRU. The governing bodies have a maximum of three months from the date of acknowledgment of the letters of claim to provide their initial responses.

FAQ’s

We aim to quickly answer any questions, to help reduce support requests and to build trust by addressing concerns transparently and consistently.

What is BHN

BHN is a UK MedTech developing a portable EEG headband and app that directly measure brain activity and use AI for instant,  objective triage of suspected head injuries without visiting hospital.

Built for sport, military, and industry, it supports fit-to-play/seek-care decisions, integrates with HL7 EHRs, and enables longitudinal tracking to reduce missed mTBI and speed care.

What is the BHN head band and app?

A lightweight headband with five flexible electrodes pairs via Bluetooth to a smartphone app, which guides a brief test, records brainwave responses, and uses AI to deliver immediate red/green status with guidance.

Results are stored securely for longitudinal tracking supporting quick “fit to play” or “seek care” decisions in sport, military, and industrial settings.

How does BHN work?

BHN delivers a three-minute auditory sequence while the headset records the brain’s electrical activity (EEG).

This elicits auditory evoked potentials (AEPs), which a secure AI model analyses to produce a clear red/green status indicating level of concern for head injury.

The app then provides recommended interventions and guidance for immediate management and return-to-play/service protocols.

 

How long does the test take?

End-to-end, the test takes about five minutes—covering headset fitting, sensor impedance verification, and the auditory sequence.

Results are delivered instantly and can be acted on immediately without specialist input.

Is a Baseline needed?

A separate baseline is not required for P300 detection when machine-learning models are trained on raw EEG. Unlike conventional workflows that rely on trial averaging and baseline correction, real-time ML can identify the P300 component directly without an explicit baseline.

Does BHN need regulatory approval?

BHN is committed to scientific credibility and future clinical applicability. We are conducting clinical validation studies in real-world settings to evidence performance and build the foundation for future medical use, regulatory pathways, and broader adoption.

The current system is non-diagnostic and supports return-to-play/service protocols—akin to consumer wearables—so we are not seeking regulatory clearance for this use. In parallel, we plan clinical studies exploring applications in neurological disorders (e.g., dementia and motor neurone disease).

Who can perform the test procedure?

The procedure can be administered by non-clinicians after brief onboarding; no formal qualifications are required.

For the initial trials, testing will be conducted by clinical staff affiliated with Super League clubs.

What is the science behind BHN?

Extensive research shows that event-related potentials (ERPs)—time-locked EEG responses to sensory, cognitive, or motor stimuli (including TMS paradigms)—are sensitive to brain injury.

Because they reflect shared neurophysiological mechanisms, injuries often produce characteristic changes in ERP latency and amplitude. BHN’s device records these signals and classifies them as normal or abnormal.

How is the data analysed?

Results are processed by a secure, cloud hosted ML model and shown in the mobile app as a clear red/green status with protocol-guided next steps.

The severity framework is clinician defined using multimodal evidence, video analysis, instrumented mouthguard data, Head Injury Assessment (HIA) outcomes, and BHN EEG readouts, to train the algorithm.

Classification is repeated during return-to-play/service to track recovery and confirm suitability.

Who decides when the brain is ready to resume activities?

If the app indicates Red, follow protocol and retest at prescribed intervals until it shows Green.

At Green status, resume activities per return-to-play/service guidelines.
