A leading psychologist has moved to clarify a widespread misunderstanding about 'mixed dementia', explaining its true nature and the symptoms families should watch for.
What 'Mixed Dementia' Really Means
Dr Kelynn Lee, CEO of the Dementia Care Hub and a specialist researcher in cognitive decline, recently addressed a common misconception on social media. She responded to a follower whose mother had received a mixed dementia diagnosis and mistakenly believed this meant doctors were unsure of the exact type.
"No. So, a mixed dementia is when a person has more than one type of dementia," Dr Lee clarified in a video cited by the Express. "Ok, so rather than just having Alzheimer’s disease, they will have Alzheimer’s disease plus vascular dementia, as an example."
She emphasised that this dual diagnosis is not a sign of uncertainty, but a confirmation that two distinct forms of dementia are present simultaneously.
The Scale and Impact in the UK
Dementia is an umbrella term for a range of progressive conditions that affect brain function, with Alzheimer's disease being the most well-known. Official NHS estimates indicate that over 944,000 people in the UK are currently living with dementia.
According to the Alzheimer's Society, mixed dementia is remarkably common, affecting one in every ten people with a dementia diagnosis. The most frequent combination is Alzheimer's disease alongside vascular dementia, which is caused by problems with the blood supply to the brain.
"The two different types of disease combine to make symptoms worse than they would be on their own," the Society's guidance states.
Recognising the Symptoms
Mixed dementia does not have a unique set of symptoms. Instead, carers and loved ones may notice signs associated with the different contributing conditions, though one type often dominates. Common symptoms across dementia types can include:
- Memory loss that disrupts daily life
- Confusion about time or place
- Difficulty following conversations or finding words
- Struggling to complete familiar tasks
- Mood changes and difficulty concentrating
The NHS notes that early signs can be mild and may be labelled as 'mild cognitive impairment' (MCI). While not everyone with MCI develops dementia, it is a potential warning sign.
"Dementia is not a natural part of ageing," NHS guidance stresses. "This is why it's important to talk to a GP sooner rather than later if you're worried about memory problems or other symptoms."
Looking Ahead: Treatment and Support
Currently, there is no cure for mixed dementia. However, treatments and support are available to help manage symptoms and maintain quality of life. Understanding the specific types involved can help in tailoring care approaches.
The key takeaway from experts is the importance of seeking professional medical advice for an accurate diagnosis. Anyone concerned about themselves or a loved one showing potential signs of dementia is urged to consult their GP promptly for assessment and guidance.
