It is estimated that the quantity of folks dwelling with dementia in the UK by 2025 will rise to over 1 million.

In the US, it is estimated there are 5.5 million Alzheimer’s victims. An identical share rise is predicted in the approaching years.

In the study — printed in the journal Nutrients — scientists recruited 33 adults in their late 50s from across the Cincinnati space who had gained weight in their center age.

Participants in each teams weighed about 205 lbs on common, and had a waist circumference of about 107 centimeters.

Their BMI scores have been 33, classing them as overweight. 

All of them have been pre-diabetic, when the physique begins to turn into proof against insulin.

Before the experiment started assessments have been carried out to measure participant’s reminiscence.

These have been repeated once more after 12 weeks of consuming the blueberries or the placebo.

Dr Robert Krikorian, the psychologist who led the study, and others stated in the paper: ‘The cognitive findings indicated improved government capability in this middle-aged pattern [who had blueberries]. 

‘The demonstration of these advantages in middle-aged people with insulin resistance and [subjective cognitive decline] means that ongoing blueberry supplementation could contribute to safety in opposition to cognitive decline when carried out early in at-risk people.’

They added: ‘In abstract, this study demonstrated that blueberry supplementation has neurocognitive profit in middle-aged people with insulin resistance and elevated danger for future dementia.’

More than 6 million Americans are thought to have dementia, the Alzheimer’s Association reports.
