Routine eye exams may help spot early signs of Alzheimer's

One way scientists think Alzheimer’s disease may be detected early is through eye health. Specifically, scientists have been looking into the retina and its blood vessels in hopes that they could help identify changes that are also occurring in the brain. Results of a recent mouse study suggest distinct vascular changes in the eyes and brain occur at the same time, and that closer eye examination could ultimately help doctors detect Alzheimer’s and related dementias sooner.

IBS, vitamin D deficiency may predict Alzheimer's, Parkinson's disease

Currently, neurodegenerative conditions, such as Parkinson’s and Alzheimer’s diseases, are challenging to preempt. A large-scale, innovative new study investigates how hormonal, dietary, metabolic, and digestive issues may help predict these conditions years before they begin. The study identifies several conditions that are associated with an increased risk of Alzheimer’s and Parkinson’s. Importantly, the findings also hint at ways to help reduce the risk of developing these disorders.

Mediterranean diet may slow cognitive decline in those at high genetic risk

Previous studies have identified specific genetic variants that may increase a person’s risk for Alzheimer’s disease, such as the APOE4 variant. A new study found that following a Mediterranean diet may help lower a person’s risk of developing dementia and decelerate cognitive decline. Scientists discovered that this protective effect was strongest in high risk participants with two copies of the APOE4 gene variant.

Low-calorie Mediterranean diet and exercise may help lower diabetes risk

About one in every nine adults around the world lives with diabetes, with 90% of them having type 2 diabetes. Past studies show that certain lifestyle factors can help lower a person’s risk for type 2 diabetes, such as exercising regularly and eating a healthy diet like the Mediterranean diet. A new study has found that a combination of following a calorie-restricted Mediterranean-style diet, plus moderate exercise and following a weight-loss program, is a more effective way to lower type 2 diabetes risk compared to only following the Mediterranean diet.

3 diet types may help reduce chronic disease risk in older adults

Researchers from Karolinska Institutet studied how dietary patterns influence the development of chronic diseases such as heart disease, dementia, and diabetes in older adults. Older adults who regularly ate healthier diets that included vegetables, whole grains, nuts, and healthy fats experienced a slower buildup of chronic illnesses. Those who consumed more red meat, processed foods, and sugary beverages were more likely to develop multiple chronic conditions over time.

3-5 cups of coffee a day linked to longer life, lower diabetes risk

A recent review gives an overview of coffee’s health benefits, considering the most recent data. For most, moderate coffee intake offers health benefits, including decreased mortality and decreased risk for some diseases like cardiovascular disease, and type 2 diabetes. There are still factors to consider, such as caffeine intake during pregnancy, decaffeinated drinks, and more research is needed.

Can metabolic syndrome substantially increase Parkinson's risk?

As much as 31% of the world’s population has metabolic syndrome. Past research shows that metabolic syndrome can lead to diseases like Parkinson’s disease. A new study provides further evidence of a correlation between metabolic syndrome and Parkinson’s disease risk. Researchers found that people with metabolic syndrome were about 40% more likely to develop Parkinson’s disease than those without the condition.

22 almonds a day may help prolong your health span, study finds

A person’s oxidative health refers to their body’s ability to keep a good balance of free radicals and antioxidants that when imbalanced, could damage body cells. Oxidative stress can be caused by a number of lifestyle factors, including eating an unhealthy diet. Past studies show that eating certain foods high in antioxidants, like nuts, may help lower a person’s risk for oxidative stress. Now a new study says that eating about 2 ounces of almonds a day may help lower oxidative stress and improve oxidative health, thus prolonging health span.

For better weight control in diabetes, turmeric may be the answer

Type 2 diabetes is a major global health concern — in 2017, around 6.28% of the world’s population lived with the condition, a proportion that is expected to rise to 7% by 2030. There are several treatments for the condition, but the global cost of treating type 2 diabetes is projected to be more than $1 trillion by 2030. A new study has found that turmeric, or its active component curcumin, may help people with prediabetes or type 2 diabetes lose weight, potentially reducing their need for costly medications.

COVID tied to faster blood vessel aging, especially in women

Since the start of the COVID pandemic in January 2020, about 768 million people globally have been infected by COVID-19. While COVID affects the respiratory system, past studies show that it can also lead to issues in other parts of the body, including the cardiovascular system. A new study has found that people who have had COVID have stiffer arteries compared to people who never had this viral infection. Scientists believe this arterial stiffening may cause early vascular aging of as much as five years.
