Memory loss is common in dementia-free elderly

A new study has highlighted that some memory loss is common in dementia-free elderly individuals.

Researchers from Duke University Medical Centre in Durham, North Carolina, studied 856 people aged 71 years and older over the course of two years.

It was found that some 22 per cent of the participants displayed symptoms of cognitive impairment without developing full-blown dementia.

Among 180 subjects with cognitive impairment without dementia who were re-assessed 16-to-18 months later, approximately 12 per cent (39) had progressed to dementia.

Dr Brenda Plassman, who led the team, told Reuters that the team are conducting further research into how cognitive impairment without dementia affects families and carers of elderly people.

She added that the study may lead toward developing interventions and treatments, so that cognitive impairment is not one of the leading concerns in late life for future generations.

According to the Alzheimer's Society, there are over 100 types of dementia. The most common are Alzheimer's disease, vascular dementia and dementia with Lewy bodies.

There are currently 700,000 people with dementia in the UK.
