Sheila Margaret Edwards · Prevention of Future Deaths report

On 14 March 2023 I commenced an investigation into the death of Sheila Margaret Edwards aged 81 years. The investigation concluded at the end of the inquest on 17 April 2025, the conclusion of the inquest was Road Traffic Collision

The cause of death was due to multiple injuries, acute pulmonary thromboembolism (clots in the lung), hypertension and chronic heart failure and contributed to by osteopaenia, osteoarthritis, and atherosclerosis.

On 8 January 2023, Sheila Margaret Edwards was a front seat passenger in a car wearing a seatbelt. Shortly before the collision, the driver of the car was behaving slightly erratically slowing down when it was inappropriate to do so. As the car drove down Shawbridge Street, Clitheroe, the driver became unresponsive despite Sheila Edwards and another passenger shouting at him although he remained upright in his seat. The car accelerated to 50 mph. Sheila Edwards grasped the wheel and steered the car into the opposite carriageway to avoid stationary traffic. Unfortunately, this resulted in a head-on collision. After the collision it was noted that the driver was confused.

On 3 June 2021 the driver had attended the Accident and Emergency Department following a 45-minute to loss of consciousness with no recollection of events during which he sustained a fall causing an abrasion to his forehead, a bruised lip and bit his tongue. He was noted to be slightly confused and a preliminary diagnosis was made of possibly a cardiovascular or neurological cause. At this time, it was unknown that the driver had mild-to-moderate dementia with good preservation of social skills and a particular deficit with his memory. The driver was referred to the medical team for assessment and gave a different history consistent with postural hypotension, which was the only abnormality detected on a bank of investigations. There was discussion between an expert in old age psychiatry expert neurologist as to whether or not the earlier or subsequent history was most reliable and on balance the earlier history was preferred.

On 4 May 2022 the driver again attended the Accident and Emergency Department with another unexplained loss of consciousness that again was attributed to postural hypotension.

The driver did not refer himself to the DVLA in respect of any of the above instances of collapse and was unaware of his mild-to-moderate dementia. The memory deficit due to the dementia made diagnosis of the underlying focal epilepsy particularly difficult due to the changing history provided to two different clinicians at different times. During the inquest it was noted that those who have no family or friends to report how they are behaving are particularly difficult to diagnose with dementia or any other cognitive deficit.

1. Dementia affects approximately half a million sufferers in the United Kingdom of which the DVLA has only been notified of approximately 30,000 drivers. It would appear that there is significant underreporting of drivers who may suffer from dementia

2. The current system for vehicle licensing relies upon the self-awareness of a driver and their ability to self-report medical conditions to the DVLA. A system that relies upon the self-awareness of a person applying for a driving licence to self-report a medical condition of dementia where the condition itself is characterised by a lack of self-awareness is inherently unsafe and exposes other road users to the risk of death or serious injury.

3. The UK population is of increasing age and the number of older drivers is increasing rapidly. As dementia is an age-related condition, the number of dementia sufferers in the population and in the driving population is expected to increase.

4. As a result of the way in which collision data is collected using Stats 19, there is a significant likelihood that dementia is under recorded in collision statistics. The nation this point regarding collision data regarding the visual aspect of collisions, the PFD report into the deaths of Mary Cunningham, Grace Foulds, Anne Ferguson and Peter Westwell should be consulted.

5. In this case, the driver suffered from focal epilepsy, which was the primary cause of the collision resulting Sheila Edwards' death. However, the memory deficit caused by dementia resulted in a lack of awareness of an underlying neurological condition. In such cases there is a substantial risk that neither of the conditions will be reported to the DVLA for monitoring. The result is that a driver with two conditions that should be monitored by the DVLA who is both unaware of their illnesses and the need to report themselves to the DVLA. This creates a substantial risk to other road users.
