Obesity may increase risk of dementia

The increase in waistlines could fuel a big rise in the number of people with dementia in the future, researchers have warned.

According to data presented at the European Congress on Obesity, stemming the rise in obesity will cut down the risk of dementia, the BBC reported.

The Alzheimer’s Society charity has suggested that regular exercise and a healthy weight are important for reducing the risk.

One study conducted on 8,500 Swedish twins showed that people with a body mass index (BMI) greater than 30- who are classified as obese- were almost four times as likely to develop dementia as those with a normal BMI.

It was claimed that even those people who were clinically overweight with a BMI between 25 and 30, were 71 percent more likely to develop dementia.

Chronic pain sufferers often experience anxiety

Researchers have suggested that patients coping with chronic pain should also be evaluated for anxiety disorders.

Lead author Kurt Kroenke, M.D., professor of medicine at Indiana University in Indianapolis, noted that health care providers are more aware of the common occurrence of depression in patients with chronic pain, and there has been less of an emphasis on anxiety.

In the new study, researchers evaluated 250 primary care patients who were being treated at a Veterans Medical Center in the Midwest. All patients had moderate to severe chronic joint or back pain that had lasted at least 3 months despite trying pain medications.

The participants were screened for five common anxiety disorders: generalized anxiety, characterized by persistent worry; panic, or sudden, repeated attacks of fear; social anxiety, characterized by overwhelming anxiety in everyday social interactions; post-traumatic stress, or a repeated feeling of danger after a stressful event; and obsessive-compulsive disorder, characterized by repeated thoughts or rituals that interfere with daily life.

Proper exercise needed for depressed patients

There`s now sufficient research data to provide specific guidance on how to prescribe exercise for people with major depressive disorder (MDD), according to researchers including an Indian origin. Despite the substantial evidence supporting the use of exercise in the treatment of MDD, previous studies have not provided a clear indication of the proper dose of exercise needed to elicit an antidepressant effect, noted Chad Rethorst, PhD, and Madhukar Trivedi, MD, of the Department of Psychiatry at the University of Texas Southwestern Medical Center, Dallas.

To fill this gap, the researchers reviewed available data from randomized controlled trials, with the goal of developing specific and detailed recommendations for clinicians on how to prescribe exercise for their patients with MDD.

Randomised trials have shown that exercise is effective in reducing depressive symptoms in patients with MDD, on its own and in conjunction with other treatments, such as antidepressant medication and/or psychotherapy.

Exercise may help to meet the need for cost-effective and accessible alternative therapies for depressive disorders—particularly for the substantial number of patients who don`t recover with currently available treatments.
