A new research has find that an aspirin a day may slow brain decline in elderly women at high risk of cardiovascular disease.
Around 500 at risk women, between the ages of 70 to 92, were tracked for five years – their mental capacity was tested at the start and end of the study.
Those taking aspirin for the entire period saw their test scores fall much less than those who had not.
The Swedish study is reported in the journal BMJ Open.
Dr. Silke Kern, one of paper’s authors, said: “Unlike other countries – Sweden is unique, it is not routine to treat women at high risk of heart disease and stroke with aspirin. This meant we had a good group for comparison.”
The women were tested using a mini mental state exam (MMSE) – this tests intellectual capacity and includes orientation questions like, “what is today’s date?”, “where are we today?” and visual-spatial tests like drawing two interlinking pentagons.
But the report found that while aspirin may slow changes in cognitive ability in women at high risk of a heart attack or stroke, it made no difference to the rate at which the women developed dementia – which was also examined for by a neuropsychiatrist.
Dr. Silke Kern added: “We don’t know the long term risks of taking routine aspirin. For examples ulcers and serious bleeds may outweigh the benefits we have seen. More work is needed. We will be following up the women in this study again in five years.”
