Strokes are linked to dementia, increases risk of the brain disease by 70%

People who have suffered a stroke are more likely to develop dementia, a study conducted by the University of Exeter Medical School confirmed. The study involved an analysis of 3.2 million people across the world. Researchers found that the link between stroke and dementia persisted even after taking into account other dementia risk factors such as blood pressure, diabetes and cardiovascular disease. “We found that a history of stroke increases dementia risk by around 70%, and recent strokes more than doubled the risk. Given how common both stroke and dementia are, this strong…

If you feel very sleepy during the day, you might be at risk of getting Alzheimer’s

People who feel very sleepy during the day are nearly three times more likely to develop Alzheimer’s disease than those who do not, a long-term study has found. The study, published in the journal SLEEP, found that adults who reported being very sleepy during the day were thrice more likely to have brain deposits of beta amyloid, a protein that is a hallmark for Alzheimer’s, years later. Researchers at Johns Hopkins University in the US suggest that getting adequate nighttime sleep could be a way to help prevent Alzheimer’s disease….

New blood test could predict second heart attack risk

A blood test that quickly and easily detects whether a person is at the risk of a secondary heart attack is being developed by scientists. The researchers at the Baker Heart and Diabetes Institute in Australia have identified plasma lipid biomarkers (fats in the blood) that improve upon traditional risk factors in predicting heart disease and stroke. The blood test is proposed to be trialled in Australia over the next 2-3 years, said Peter Meikle, a professor Baker Heart and Diabetes Institute. Eventually this test will help better assess a…

Breastfeeding might cut off stroke risk: Study

A new research has found that breastfeeding can reduce stroke risk in post-menopausal women. The study, which was published in the Journal of the American Heart Association showed 23 per cent lower risk of stroke among breastfeeding women. “Some studies have reported that breastfeeding may reduce the rates of breast cancer, ovarian cancer and risk of developing Type-2 diabetes in mothers,” said lead author Lisette T. Jacobson, Assistant Professor at the University of Kansas School of Medicine-Wichita. Recent findings point to the benefits of breastfeeding on heart disease and other…

E-cigarettes are as dangerous as smoking. It can double the risk of heart attack

A new study has found that smoking an e-cigarette on a regular basis could double the risk of a heart attack. According to a new analysis of a survey of nearly 70,000 people, led by researchers at UC San Francisco, the dual use of e-cigarettes and conventional cigarettes appears to be more dangerous than using either product alone. The study also found that the risks compound, so that daily use of both e-cigarettes and conventional cigarettes raises the heart attack risk five-fold in comparison to the people who don’t use…

Here’s how heart diseases affect men and women differently. Find out if you’re at risk

Heart diseases have emerged as the leading cause for fatalities in men and women world over and also in India. The risk of heart diseases to both sexes is grave, but heart diseases affect men and women differently. Over one crore annual deaths are reported in India and cardiovascular diseases (CVD) cause 20.3% deaths in men and 16.9 percent deaths in women. Despite having a lower mortality rate than men, reports have often suggested that women are more at risk of CVD related deaths. Another Indian study reports that the incidence…
