Air pollution linked to higher risk of dementia: study

PARIS: Urban air pollution, mostly from vehicles, is associated with an increased risk of dementia, according to research published Wednesday. The link remained even after heavy drinking, smoking and other well established risk factors for dementia were ruled out, the researchers reported in medical journal BMJ Open. Worldwide, about seven percent of people over 65 suffer from Alzheimer's or some form of dementia, a percentage that rises to 40 percent above the age of 85. The number afflicted worldwide is expected…

Dementia risk doubles right after a stroke: study

CALIFORNIA: People who have recently experienced a stroke may be more than twice as likely to develop dementia than individuals who haven’t had a stroke, a new study suggests. While stroke has long been linked to a heightened risk of dementia, particularly in older adults, the exact magnitude of the increased risk hasn’t been consistent across previous studies investigating this connection. For the current study, researchers pooled data from 48 previous studies with a total of 3.2 million participants worldwide. People…

Dementia patients may benefit from music therapy

NEW YORK: Music therapy may improve depression and anxiety in dementia patients, a new analysis suggests. Music therapy might also improve emotional well-being among those with dementia, researchers found. But they didn’t find any benefits when it came to cognition and behavioral issues such as agitation or aggression, according to the report in the Cochrane Library journal. Although the benefits of music therapy weren’t large, “small effects are valuable, too, because even a small improvement or maintaining a certain…

Exercise does not delay decline in people with dementia: study

PARIS: While physical exercise may stave off dementia, it does not delay mental decline in people after they've been diagnosed, a study in nearly 500 people with the condition reported Thursday. While a fitness regime improved physical fitness in people with mild to moderate dementia, it "does not slow cognitive impairment," researchers reported in The BMJ medical journal. It is generally accepted that exercise can delay the onset of Alzheimer's and other forms of dementia. But whether or not it can slow symptoms after…

Robot dog lends a helping paw to dementia sufferers

BOURNEMOUTH, ENGLAND: Among Ron Grantham’s happiest memories are the days he spent fly-fishing with his beloved dog, Spot. Now those memories are being revived by visits from his new best friend, Biscuit - a robotic dog. Grantham is 99 years old and lives in Templeman House, a British care home, which brought in Biscuit. Staff there say dogs - even robotic dogs - can help to elicit memories from residents and spark conversations with care providers. “I found out today that Ron used to go fly fishing when he finished…

Marriage linked to lower dementia risk: research

NEW YORK: Being married, or ever having been married, comes with a much lower risk of developing dementia compared to being a lifelong bachelor or bachelorette, a new analysis of previous studies suggests. Researchers found that people who never married were 42 percent more likely than those who were married at midlife to ever be diagnosed with dementia. Being divorced, though, was not tied to higher dementia risk compared with the folks who stayed married. “Our findings, from large populations across numerous…

Researchers in US report promising new Alzheimer’s drug

WASHINGTON: A new experimental treatment against Alzheimer's has proved to be promising and free of harmful side effects, researchers in the United States reported Wednesday. The research published in the journal Science Translational Medicine on the basis of a small 32-person sample gave rise to two broader clinical trials that are now underway with more than 3,000 subjects. The treatment uses a compound called verubecestat, developed by US pharmaceutical firm. It reduces levels of proteins called beta amyloids by…
