People with heart disease are at higher risk for cognitive impairment, providing more evidence of the interconnection between our physical and mental health. Mayo Clinic researchers found that in a study of more than 2,719 people aged 70–89, those with heart disease—especially women—were more likely to experience mild cognitive impairment, exemplified by problems with language, thinking and judgment.
Study findings appeared in JAMA Neurology
(2013; doi: 10.1001/jamaneurol.2013.607).
Maintaining a consistent twice-weekly yoga practice helped people with cardiac arrhythmia improve symptoms and reduce anxiety, noted a study published in the Journal of the American College of Cardiology (2013; doi: 10.1016/j.jacc.2012.11.060).
1. Since high blood glucose is dangerous, is low blood glucose healthy?
When blood glucose levels fall below 70 mg/dl, the condition is called hypoglycemia or low blood glucose. Since the primary fuel of the central nervous system (CNS) is glucose, low blood glucose can dramatically impair CNS function. Hypoglycemia can lead to dizziness, confusion, slurred speech, blurred vision and sleepiness (Gulve 2008).

By now you’ve probably heard about the American Medical Association’s decision to classify obesity as a disease.
“Recognizing obesity as a disease will help change the way the medical commu-nity tackles this complex issue that affects approximately one in three Americans,” explained AMA board member Patrice Harris, MD, at the AMA annual meeting. “The AMA is committed to improving health outcomes and is working to reduce the incidence of cardiovascular disease and type 2 diabetes, which are often linked to obesity.”
Growing numbers of people are turning to alternative approaches to complement or reduce the use of medication for controlling blood pressure. To guide physicians on the variety of complementary therapies, the American Heart Association has issued a scientific statement entitled “Beyond Medications and Diet: Alternative Approaches to Lowering Blood Pressure,” available in the AHA’s journal Hypertension (2013; 61 , 1360–83; doi: 10.1161/HYP.0b013e318293645f).
For older adults, volunteering may be an effective activity that not only helps their communities but also promotes personal health. Carnegie Mellon University researchers in Pittsburgh found that older adults who volunteer at least 200 hours per year in any type of activity decrease their risk of hypertension by as much as 40%.
While keeping a healthy cholesterol profile is important for everyone, middle-aged men with high cholesterol have a greater risk of first-time heart attack than middle-aged women with the same condition, researchers reported.
The scientists observed Norwegian women (23,525) and men (20,725), all younger than 60 at baseline, for 12 years. They looked at cholesterol scores and noted any incidence of acute myocardial infarction (AMI), or heart attack, among the subjects.
