Mixed dementia means having more than one type of dementia.

A psychologist clarified that 'mixed dementia' means a person has more than one form of dementia, and UK figures cited in the report put dementia prevalence at over 944,000 with about one in 10 people with dementia having mixed dementia.

Dr Kelynn Lee, CEO of the Dementia Care Hub and a researcher on cognitive decline, explained the meaning of 'mixed dementia' in a response on TikTok. She said mixed dementia occurs when a person has more than one type of dementia, for example Alzheimer's disease alongside vascular dementia. Her clarification addressed a common misunderstanding that the term indicates diagnostic uncertainty. Dementia is an umbrella term for conditions marked by gradual decline in brain function. Key facts: - Dr Kelynn Lee explained that mixed dementia means a person has more than one type of dementia rather than an unclear diagnosis. - The article cites NHS data that more than 944,000 people in the UK live with dementia and the Alzheimer's Society estimate that about one in 10 people with dementia have mixed dementia. - Mixed dementia does not have a single specific symptom profile; symptoms often reflect the individual conditions involved, and symptoms from one type are usually more noticeable than those from others. Summary: Dr Lee's explanation clarifies that mixed dementia combines different dementia types rather than reflecting uncertainty about the diagnosis. The reporting notes UK prevalence figures and the estimate that mixed dementia affects about one in 10 people with dementia. Undetermined at this time.
