A new study by scientists from Imperial College London finds that people with higher levels of iron are at greater risk of having a stroke, especially the kind of stroke that results from a blood clot or other obstacle traveling from the heart.
For the study, the researchers used genetic information on over 48,000 people from public sources. With the help of technique Mendelian randomization, the researchers identified three “single-letter alterations,” or single nucleotide polymorphisms (SNPs), in their DNA that can raise or reduce the iron status of the individual.
Lead study author Dr. Dipender Gill says: “All these findings highlight potential treatments or lifestyle interventions that may help reduce stroke risk, and that they may offer avenues for further study.”
A new study, conducted by the scientists from the University of Gothenburg in Sweden, finds that light and moderate physical activity, for example walking and swimming, may help reduce the stroke severity.
The study included approximately data from 1,000 individuals who had had a stroke. Having performed the given data, the researchers concluded that those who had been doing several hours of light or moderate physical exercises had less severe strokes compared to those who hadn’t been performing any exercises.
Katharina S. Sunnerhagen, the author of the study, says: “There is a growing body of evidence that physical activity may have a protective effect on the brain and our research adds to that evidence.”
New research, conducted by a team of scientists from McMaster University in Ontario, Canada, finds that people who consume three servings of dairy, including milk, cheese, butter, or cream, a day are almost two times less likely to suffer from heart disease and strokes than people who consume less dairy.
For their study, the researchers analyzed the data from more than 136,000 people from 21 countries aged between 35 and 70 who had taken part in the Prospective Urban Rural Epidemiological (PURE) study. The study focused on environmental, societal, and biological effects on obesity and chronic health issues.
Dr. Mahshid Meghan, a senior research associate at McMaster University, explains: “What I really want to emphasize is that consumption shouldn’t be discouraged but encouraged especially in low-income countries and even in high-income countries where consumption is low. We are not saying people eating seven servings of dairy a day should increase their intake, but that three servings – moderation – is good for you.’
According to a recent analysis of existing studies in the UK, single, divorced and widowed people have higher chances to develop heart disease and stroke. That’s why the authors of the study believe that being married can be another factor that cuts the risk of cardiovascular disease.
For the study, a team of researchers examined 34 studies from around the world which included over 2 million participants altogether aged from 42 to 77. The results of the analysis showed that single, divorced or widowed people had 42% higher risk of developing cardiovascular disease compared to married participants.
Lead study author Chun Wai Wong and colleagues conclude: “Future research should focus around whether marital status is a surrogate marker for other adverse health behavior or cardiovascular risk profiles that underlines our reported findings or whether marital status should be considered as a risk factor by itself.”
Women are more vulnerable to strokes than men due to hormones. Nicole Weinberg, M.D., a cardiologist from Providence Saint John’s Health Center in California explains: “Higher hormone levels, particularly estrogen, compromise the integrity of blood vessels. They affect how the vessels stretch and contract, which can make them more vulnerable to arterial dissection [tears] and blood clots.”
Women taking birth control pills, illegal drugs or those who are smoking or pregnant are even at higher risk of a stroke. Stroke symptoms in younger women may differ from the stroke symptoms in older women or men. Here is the list of all stroke symptoms — those, common to all, and those that are only typical for younger women:
Your face looks really off.
Feeling clumsy and weak.
It’s hard to speak.
Dizziness and nausea.
A really strong headache.
Persistent incurable hiccups.
Sudden, drastic, unexplained changes in your personality or mental state.
