In this article, we explore key legal considerations and, through a case study shared by our trusted member, Dean Wilson LLP, demonstrate why finding the right legal representation is crucial in complex cases. We also highlight how our trusted members can support beyond legal matters by connecting you with case managers, rehabilitation specialists, and financial planners.

Recognising Hidden Injuries and the Importance of Early Legal Advice

After a road traffic accident, understanding your legal needs begins with recognising that injuries are not always immediately apparent or fully understood at the time of the incident. While some claims involve straightforward physical recovery, others develop into more complex conditions where symptoms emerge over time. This can include neurological complications, psychological distress, or a combination of both, which may significantly affect a person’s ability to work, function independently, and maintain quality of life.

In cases involving potential traumatic brain injury or psychiatric symptoms, early legal advice is particularly important. These claims often require specialist assessment to determine the full extent of injury and whether there is a causal link between the accident and subsequent medical conditions. Expert evidence is frequently needed to clarify whether symptoms are directly attributable to the accident or influenced by pre-existing vulnerabilities, making early instruction of experienced solicitors and medical experts essential.

How long do I have to make a Road Traffic Accident claim?

You have three years from the date of the accident to bring a legal claim. This time limit is set by the Limitation Act 1980 to ensure that evidence remains available, witnesses can recall events accurately, and defendants are protected from indefinite liability. However, where a person lacks mental capacity to make decisions—particularly in brain injury cases—there is no time limit for bringing a claim on their behalf.

Why Specialist Personal Injury Solicitors Matter

At the Brain Injury Group we have a panel of solicitors who have many years’ experience advocating for individuals with life changing brain injuries – they value their clients and their families full needs, connecting with medical professionals within the sector to ensure all needs are met. They develop relationships ensuring each client’s story is told fully, accurately and with long term vision.

Choosing a solicitor who specialises not only in personal injury but with a understanding of brain injury cases is essential because these cases often involve complex medical evidence, detailed liability assessments, and long-term financial forecasting that go far beyond general legal practice. Specialist personal injury solicitors have the experience to identify key issues early, instruct the right medical experts, and build a case that properly reflects the full extent of an individual’s injuries and future needs. They are also better equipped to handle disputes over causation, pre-existing conditions, and insurance arguments, which frequently arise in serious road traffic accident claims.

Importantly, a specialist will understand how to secure rehabilitation support and interim funding where needed, ensuring that clients receive both legal and practical assistance from the outset of their recovery.

Dean Wilson Case Study – Complex Brain Injury & Psychiatric Overlap

This case study demonstrates how a seemingly straightforward road traffic accident can evolve into a complex legal matter involving both neurological injury and psychiatric complications. In such cases, identifying the right legal approach early helps secure appropriate rehabilitation, obtain key medical evidence, and properly assess the long-term impact of the injuries.

The Claimant, riding a Vespa, was forced to take evasive action when the Defendant pulled out from a side road without noticing them. They sustained a significant head laceration and jaw injury and were initially discharged from hospital. Around five weeks later, however, they experienced a severe psychotic episode, resulting in readmission under section.

Further medical investigations revealed micro-haemorrhages consistent with a traumatic brain injury caused by the accident. While the physical effects improved over time, there was significant dispute regarding the ongoing psychiatric condition—specifically whether it was post-traumatic psychosis or bipolar disorder, and if it was bipolar whether it was caused or materially contributed to by the accident.

Liability was admitted early, and interim payments were secured to support rehabilitation. The main issue remained causation and prognosis, with complex neuropsychiatric evidence required to determine whether the condition was accident-induced or linked to an underlying predisposition.

Medical Evidence and Causation in Dispute

This required a detailed analysis of the medical literature in respect of bipolar disorder and the risks associated with developing the condition following an acquired brain injury. It was the Claimant’s case that this was not bipolar disorder; however, if it was bipolar, it would not have developed but for the accident and the TBI, and therefore the TBI materially contributed to its development.

The Defendant’s case was that the Claimant would have developed bipolar disorder within a couple of months of the index accident in any event, as they were already constitutionally predisposed to developing the condition during their lifetime, and thus no ongoing future losses were attributable to the accident.

Due to Dean Wilson’s experience and connections with medical experts within the industry, and following detailed expert analysis and reference to medical literature—including studies indicating a significantly increased risk of bipolar disorder following TBI—the parties reached a six-figure settlement at a joint settlement meeting in July 2025. The award reflected the Claimant’s inability to return to full-time employment and the need for ongoing care and support, including treatment for potential future relapses.

The Claimant was represented by Alex Brown and Lyubov Nikolchova at Dean Wilson and expertly assisted by Counsel, Perrin Gibbons of Deka Chambers.

Final Thoughts: Getting the Right Support After a Road Traffic Accident

Every road traffic accident claim is unique, and as this case demonstrates, injuries can evolve in unexpected and complex ways over time. What may initially appear to be a straightforward injury can, in some circumstances, develop into a long-term condition involving both neurological and psychiatric challenges.

This is why early access to the right legal and medical support is so important. At the Brain Injury Group, we are here to help individuals and families navigate these challenges by connecting them with specialist solicitors, rehabilitation professionals, and ongoing support services. If you or a loved one has been affected by a road traffic accident or a brain injury, seeking early advice can make a significant difference to both recovery and long-term outcomes.
