glass-of-wineDrinking even “moderate” amounts of alcohol increases dementia risk.

Light to moderate alcohol consumption has generally been considered to have some health benefits, including possibly reducing risk of cognitive decline. However, two studies reported today at the Alzheimer’s Association International Conference® 2012 (AAIC®2012) in Vancouver suggest that moderate alcohol use in late-life, heavier use earlier in life, and “binge” drinking in late-life increase risk of cognitive decline.

“The many dangers of misuse of alcohol, and some of its possible benefits, have been widely reported, and there needs to be further clarification by the scientific community,” said William Thies, PhD, Alzheimer’s Association® chief medical and scientific officer. “Certainly no one should start drinking in order to reduce Alzheimer’s risk, as these two new reports attest.”

“We need to know more about what factors actually raise and lower risk for cognitive decline and Alzheimer’s disease. To do that, we need longer term studies in larger and more diverse populations, and we need more research funding to make that happen. We have learned incredible amounts about heart disease and stroke risk from long-term research like the Framingham Study – we have solidly proven lifestyle risk factors that people can act on every day. Alzheimer’s now needs its version of that research,” Thies added. [continue reading…]

Specific types of “mindfulness practices” including Zen meditation have research-proven benefits for patients with certain physical and mental health problems, according to a report in the July Journal of Psychiatric Practice. The journal is published by Lippincott Williams & Wilkins,a part of Wolters Kluwer Health.

“An extensive review of therapies that include meditation as a key component—referred to as mindfulness-based practices—shows convincing evidence that such interventions are effective in the treatment of psychiatric symptoms and pain, when used in combination with more conventional therapies,” according to Dr William R. Marchand of the George E. Wahlen Veterans Affairs Medical Center and the University of Utah in Salt Lake City.
Mindfulness Techniques Show Health Benefits

Dr Marchand reviewed published studies evaluating the health benefits of mindfulness-based practices. Mindfulness has been described as “the practice of learning to focus attention on moment-by-moment experience with an attitude of curiosity, openness, and acceptance.” Put another way,
“Practicing mindfulness is simply experiencing the present moment, without trying to change anything.”

The review focused on three techniques:

Zen meditation, a Buddhist spiritual practice that involves the practice of developing mindfulness by meditation, typically focusing on awareness of breathing patterns.

Mindfulness-based stress reduction (MBSR), a secular method of using Buddhist mindfulness, combining meditation with elements of yoga and education about stress and coping strategies.

Mindfulness-based cognitive therapy (MBCT), which combines MBSR with principles of cognitive therapy (for example, recognizing and disengaging from negative thoughts) to prevent relapse of depression.

Dr Marchand found evidence that MBSR and MBCT have “broad-spectrum” effects against depression and anxiety and can also decrease general psychological distress. Based on the evidence, MBCT can be “strongly recommended” as an addition to conventional treatments (adjunctive treatment) for unipolar depression. Both MBSR and MBCT were effective adjunctive treatments for anxiety.

Research data also supported the effectiveness of MBSR to help reduce stress and promote general psychological health in patients with various medical and/or psychiatric illnesses. On its own, MBSR was helpful in managing stress and promoting general psychological health in healthy people.

There was also evidence that Zen meditation and MBSR were useful adjunctive treatments for pain management.

How do these practices work to affect mental and physical health? Dr Marchand discusses recent research showing the impact of mindfulness practices on brain function and structure, which may in part account for their psychological benefits. “These mindfulness practices show considerable promise and the available evidence indicates their use is currently warranted in a variety of clinical situations,” he concludes.
The article includes some proposed evidence-based guidelines for incorporating mindfulness-based practices into health care. So far there’s little evidence on which patients are most likely to benefit, but Dr Marchand suggests that patient preferences and enthusiasm are a good guide. He comments, “The most important considerations may be desire to try a mindfulness-based practice and willingness to engage in the regular practice of seated meditation.”

University at Buffalo

A landmark study of police officers in Buffalo, N.Y., reveals increased incidence of chronic disease, finds suicides higher among those still working.

The daily psychological stresses that police officers experience in their work put them at significantly higher risk than the general population for a host of long-term physical and mental health effects. That’s the overall finding of a major scientific study of the Buffalo Police Department called Buffalo Cardio-Metabolic Occupational Police Stress (BCOPS) conducted over five years by a University at Buffalo researcher.

“This is one of the first police population-based studies to test the association between the stress of being a police officer and psychological and health outcomes,” says John Violanti, PhD, professor of social and preventive medicine in the UB School of Public Health and Health Professions, and principal investigator on the study, funded by the National Institutes of Health.

The research, which is in press this month in a special issue of the International Journal of Emergency Mental Health, reveals connections between the daily stressors of police work and obesity, suicide, sleeplessness and cancer, as well as general health disparities between police officers and the general population.

The study was prompted by the assumption that the danger, high demands and exposure to human misery and death that police officers experience on the job contribute to an increased risk of cardiovascular disease and other chronic health outcomes.

“We wanted to know, in addition to stress, what are other contributing factors that lead to cardiovascular disease in police?,” says Violanti, a former New York State trooper. [continue reading…]
