Stroke survivors who have irregular heart rhythm atrial fibrillation could have a higher risk of dementia, research has indicated.
Scientists from the University of East Anglia in Norfolk found that among stroke survivors, those with atrial fibrillation were 2.4 times more likely to develop dementia.
Study author Phyo Kyaw Myint, said that the results could help to identify potential new treatments which could stave off the onset of dementia.
"Options could include more rigorous management of cardiovascular risk factors or of atrial fibrillation, particularly in stroke patients," he added.
This comes after the Alzheimer's Society projected that more than half a million people will be living with undiagnosed dementia by 2021.
The charity is teaming up with Tesco to raise £5 million to build a better future for those with the condition and to raise diagnosis levels from 40 per cent by 2014.
