According to research, patients dealing with type 2 diabetes, heart disease or stroke accelerate the risk of developing dementia.Prevention of diabetes and cardiovascular disease could, therefore, be a strategy for reducing dementia risk, suggests a study from Karolinska Institutet in Sweden published in the journal Alzheimer's & Dementia suggests.Type 2 diabetes, heart diseases (ischemic heart disease, heart failure or atrial fibrillation) and stroke - so-called cardiometabolic diseases - are some of the main risk factors for dementia."Few studies have examined how the risk of dementia is affected by having more than one of these diseases simultaneously, so that's what we wanted to examine in our study," says Abigail Dove, a doctoral student at the Aging Research Centre, part of the Department of Neurobiology, Care Sciences and Society, Karolinska Institutet.Dementia develops slowly over decades. It first manifests as gradual cognitive decline that only shows up in cognitive tests. It then degenerates into cognitive impairment in which the individual notices their failing memory but can still look after themselves, and finally into full-blown dementia.More than one cardiometabolic disease doubles the riskThe researchers extracted data from the Swedish National Study on Aging and Care on a total of 2,500 healthy, dementia-free individuals over the age of 60 living on Kungsholmen in Stockholm. At the start of the study, the incidence of cardiometabolic diseases was assessed through medical records and clinical investigation. The participants were then followed for twelve years with medical examinations and cognitive tests in order to monitor changes in cognitive ability and the development of dementia.The presence of more than one cardiometabolic disease accelerated the speed of the cognitive decline and doubled the risk of cognitive impairment and dementia, expediting their development by two years. The magnitude of the risk was increased with a greater number of diseases."In our study, the combinations of diabetes/heart disease and diabetes/heart disease/stroke were the most damaging to cognitive function," says Dove.Prevention of a second disease importantHowever, individuals who had just one cardiometabolic disease did not display a significantly higher risk of dementia."This is good news. The study shows that the risk only increases once someone has at least two of the diseases, so it's possible that dementia can be averted by preventing the development of a second disease."The correlation between cardiometabolic diseases and the risk for dementia was stronger in the participants who were under 78 years old."We should therefore focus on cardiometabolic disease prevention already in middle age since the risk of cognitive failure and dementia appears higher among those who develop a cardiometabolic disease earlier in life," says Dove.( With inputs from ANI )Disclaimer: This post has been auto-published from an agency feed without any modifications to the text and has not been reviewed by an editor
