Younger onset dementia (YOD) is defined as the onset of dementia symptoms before age 65. Researchers in Sydney, Australia contacted local health professionals and hospitals to determine how many patients were classified as having YOD. Then, they compared that information with recent census data. The research team found that YOD affects 11.6 per 100,000 people ages 30-44 years and 132.9 per 100,000 people ages 45-64 years, with an overall prevalence rate of 68.2 per 100,000 people for ages 30-64.

Previous research has suggested that high levels of vitamin D may protect individuals from developing type 2 diabetes; however, a new study has found no evidence that high levels of vitamin D can prevent type 2 diabetes and that the only proven way to prevent type 2 diabetes is through a combination of diet and exercise. Study author Dr. Nita Forouhi writes, “Our findings suggest that interventions to reduce the risk of type 2 diabetes by increasing concentrations of vitamin D are not currently justified. Observational studies that show a strong and consistent higher risk of type 2 diabetes with lower levels of vitamin D may do so because they have thus far not been able to adequately control for distorting or confounding factors, such as physical activity levels.”

A survey of prior research concludes that organically grown foods are about 48% lower in cadmium than conventionally grown foods. Cadmium is a heavy metal that has become a major cause of vascular disorders, common cancers, osteoporosis, kidney disease, and can damage the reproductive and neurological systems. Researcher Dr. James J. DiNicolantonio adds, “For years, nutritionists and consumers have struggled with the question, ‘is organic really better?’… What analysis of this research reveals is that, due to the serious health impacts of cadmium exposure and the markedly lower levels of [cadmium] in organically grown foods, the long-term consumption of such foods is likely to be notably protective with respect to a wide range of common pathologies.”

Physiology researchers have found that having your ‘eye on the prize’ makes exercise less of a chore. They found that when walking, individuals who stay focused on a specific target ahead of them feel the distance is shorter and they walk faster towards it. Researcher Dr. Shana Cole writes, “Interventions that train people to keep their ‘eyes on the prize’ may play an important role in health and fitness. When goals appear within reach, and when people move faster and experience exercise as easier, they may be especially motivated to continue exercising. Given the alarming obesity epidemic in America, strategies that encourage or improve exercise may be particularly important for aiding the nationwide effort to combat obesity and promote healthier living.”

Using data provided by 680 seniors (age > 70 years) regarding mobility limitations and joint stiffness upon waking, researchers say that morning joint stiffness more than one body site is associated with a 64% greater risk developing new or worsening mobility problems over the following 18 months. The authors of the study recommend that doctors discuss strategies for improving joint mobility with their patients to prevent or slow the progression of age-related disability.

If you have high blood pressure and you live close to a major highway, you may want to move. According to a new report, participants in a study who lived within 109 yards (~100 meters) of a busy road had a 22% higher risk for developing high blood pressure compared with those who lived at least a half a mile away (~.8 km). Further research is needed to determine if reducing exposure to traffic noise and traffic-related air pollution can reduce a nearby resident’s risk of high blood pressure.
