Overeating 'can make you forgetful'

Eating too much can increase the risk of memory problems in old age by 100%, according to research.

Scientific studies in America found that a high intake of calories can significantly increase the risk of mild cognitive impairment (MCI).

Those with the impairment will often suffer memory loss, which can be followed by dementia.

The findings of the research were made public before the American Academy of Neurology's 64th yearly meeting in April, which will be held in New Orleans.

At the meeting, the authors will present the developments.

Alzheimer's Research UK's Dr Marie Janson said the findings 'touch on an interesting subject'.

'The initial report suggests older people who consume a high number of calories may be at greater risk of developing mild cognitive impairment,' she said.

'It would be interesting to see how many of these people go on to develop dementia in the future, to see if there is link to Alzheimer's disease.

'We know that age is one of the greatest risk factors for dementia, but adopting a healthy lifestyle, including a balanced diet and regular exercise, is beneficial in protecting against dementia along with a number of other chronic diseases.'

She added than some 820,000 people live with dementia in the UK - a number which is likely to rise as the population becomes older.

She said we desperately need to understand more about the risk factors involved and must make investments in research.
