(NaturalNews) Would you be willing to make six simple lifestyle changes if you knew you could lower your risk of developing Alzheimer`s disease by 50%? Researchers publishing the result of a study in the journal Lancet Neurology found that the exploding incidence of this horrific form of dementia is due in large part to lifestyle changes involving diet, physical activity and education. Alzheimer`s disease incidence is expected to triple over the next forty years, meaning that millions of new cases could be prevented by modifying controllable lifestyle risks. Scientists listed the six most important factors that can be modified in an effort to significantly lower Alzheimer`s disease risk.
Researchers analyzed dozens of Alzheimer`s studies from around the world that examined hundreds of thousands of participants to determine why this insidious disease is growing at an unprecedented rate. Dr. Deborah Barnes, lead scientist performing the review, concluded that there are six significant and modifiable risk factors that contribute to the development and progression of the disease. Her team listed the factors in descending order of magnitude: low education, smoking, physical inactivity, depression, mid-life hypertension, diabetes and mid-life obesity.
As a group, these risk factors account for 54% of the diagnosed cases of Alzheimer`s disease in the United States, accounting for 2.9 million individuals. Dr. Barnes commented on the findings, “What`s exciting is that this suggests that some very simple lifestyle changes, such as increasing physical activity and quitting smoking, could have a tremendous impact on preventing Alzheimer`s and other dementias in the United States and worldwide.” The team will now work to determine if the relationship between each identified risk factor is casual or specifically attributable to disease development.
Further research into contributing factors that increase risk for developing Alzheimer`s dementia are published in the journal Archives of Internal Medicine. Scientists compared physical activity duration and intensity with the development of cognitive impairment known to be a precursor to the memory-robbing illness. As participants` energy expenditure increased, the rate of cognitive decline decreased. The amount of exercise equivalent to a brisk, 30-minute walk every day was associated with lower risk of cognitive impairment.
Alzheimer`s disease cases have multiplied exponentially over the past 50 years, leading health-minded practitioners and followers to ask for an explanation. Our lifestyle has changed dramatically during this time period, and diet, physical activity and diseases of excess have hindered the forward progress of our cognitive health. Adopting a natural diet low in sugar and refined carbohydrates combined with regular and moderate physical activity can slash many risk factors associated with Alzheimer`s dementia.
(NaturalNews) While city living offers many amenities and advantages not found in rural living, it might have a downside in the area of mental health. City dwellers generally are more stressed and are at a higher risk of developing mental illness than their rural counterparts. Although scientists have been aware of this, they did not know the reason why. A new study has revealed certain alterations in brain function that could potentially provide the explanation: Time Healthland reports.
Previous research indicates that those who grow up in a city have a two- to three-fold higher likelihood of developing schizophrenia. In addition, earlier studies show that even after reaching adulthood, city living raises the probability of contracting anxiety disorders by 21% and mood illnesses, such as depression, by 39% compared with rural dwellers.
The new study has provided further enlightenment on the issue. In an international investigation published in the journal Nature, researchers at University of Heidelberg and McGill University report that city dwellers or those who were raised in cities display definite characteristics of activity in specific areas of the brain that are not found in rural dwellers. The study pinpointed two areas of the brain that seem to be involved in responding to stress. Read more:
