Dementia

With thanks to the Alzheimers Society 

Dementia is something we most commonly associate with post-retirement adults. However, 3.3% of those with dementia are 'young onset'. Research suggests that the prevalence of dementia in the 30-64 age group is 38-260 per 100,000 population. 

Dementia is a general term for conditions which affect the brain and cause a decline in cognitive function. 

It can cover conditions such as Alzheimer's Disease, posterior cortical atrophy (PCA), and frontotemporal dementia. Both PCA and frontotemporal dementia often affect people under the age of 60. 

PCA affects visual processing skills, and it can start subtly and take time to get a diagnosis.  

Frontoemporal dementia often causes problems with behaviour and language. 

Alzheimer's Disease often primarily features memory lapses and confusion. 

Effect on road safety 

Many people with dementia-causing conditions continue to drive. However, any disruption to cognitive, visual processing, memory or decision-making skills can be a hazard when driving. Individuals should take the advice of their specialist or GP as to whether they can continue to drive safely. 

Alzheimer's UK says: 

"The common symptoms of dementia can affect all the skills needed for driving – this is why the driver licensing agencies must know about it. As dementia gets worse, it affects these skills even more. This means everyone with dementia will eventually be unable to drive safely." 

What employers can do 

If someone appears to be struggling with tasks they could previously do without problem, like word-finding, remembering routes, or judging parking spaces, then suggest they see their GP. There are many reasons they may be having difficulties. 

Assess their safety while awaiting diagnosis and treatment. This must be done on a case-by-case basis. 

If someone appears to have visual processing problems – for instance, judging distances, finding objects or recognising faces – but their eye test shows nothing unusual, ensure they follow up with their GP. 

If a person with dementia symptoms wishes to continue driving for work, you will need to check this with your vehicle insurer.
