High Blood Pressure May Prognosticate Dementia in Some Elderly Peoples

High Blood Pressure May Prognosticate Dementia in Some Elderly Peoples.
High blood stress may announce dementia in older adults with impaired executive use (difficulty organizing thoughts and making decisions), but not in those with memory problems, a new study has found. The mull over included 990 dementia-free participants, average age 83, who were followed-up for five years.

During that time, dementia developed in 59,5 percent of those with and in 64,2 percent of those without leading blood pressure. Similar rates were seen in participants with homage dysfunction alone and with both memory and leader dysfunction.

However, among those with executive dysfunction alone, the rate of dementia development was 57,7 percent surrounded by those with high blood pressure compared to 28 percent for those without high blood pressure, which is also called hypertension. "We show herein that the nearness of hypertension predicts progression to dementia in a subgroup of about one-third of subjects with cognitive impairment, no dementia," wrote the researchers at the University of Western Ontario in Canada.

So "Control of hypertension in this inhabitants could falling off by one-half the projected 50-percent five-year rate of sequence to dementia." The study findings are published in the February issue of the journal Archives of Neurology. The findings may assay important for elderly people with cognitive impairment but no dementia, the den authors noted.

Head Injury With Loss Of Consciousness Does Not Increase The The Risk Of Dementia

Head Injury With Loss Of Consciousness Does Not Increase The The Risk Of Dementia.
Having a damaging genius injury at some measure in your life doesn't raise the risk of dementia in old age, but it does increase the odds of re-injury, a uncharted study finds. "There is a lot of fear among people who have sustained a brain wound that they are going to have these horrible outcomes when they get older," said senior author Kristen Dams-O'Connor, underling professor of rehabilitation medicine at the Icahn School of Medicine at Mount Sinai Medical Center in New York City. "It's not true. But we did determine to be a risk for re-injury".

The 16-year swat of more than 4000 older adults also found that a recent traumatic brain injury with unconsciousness raised the probability of death from any cause in subsequent years. Those at greatest risk for re-injury were people who had their sense injury after age 55, Dams-O'Connor said. "This suggests that there are some age-related biological vulnerabilities that come into amuse oneself in terms of re-injury risk".

Dams-O'Connor said doctors need to look out for health issues amid older patients who have had a traumatic brain injury. These patients should try to sidestep another head injury by watching their balance and taking care of their overall health. To investigate the consequences of a shocking brain injury in older adults, the researchers collected data on participants in the Adult Changes in Thought study, conducted in the Seattle region between 1994 and 2010. The participants' unexceptional age was 75.

At the start of the study, which was published recently in the Journal of Neurology, Neurosurgery & Psychiatry, none of the participants suffered from dementia. Over 16 years of follow-up, the researchers found that those who had suffered a distressing intellect injury with loss of consciousness at any time in their lives did not increase their risk for developing Alzheimer's or other forms of dementia.

Physical Activity And Adequate Levels Of Vitamin D Reduces The Risk Of Dementia

Physical Activity And Adequate Levels Of Vitamin D Reduces The Risk Of Dementia.
Physical pursuit and acceptable levels of vitamin D appear to abridge the risk of cognitive decline and dementia, according to two large, long-term studies scheduled to be presented Sunday at the International Conference on Alzheimer's Disease in Hawaii. In one study, researchers analyzed matter from more than 1200 mortals in their 70s enrolled in the Framingham Study. The study, which has followed populate in the town of Framingham, Mass, since 1948, tracked the participants for cardiovascular health and is now also tracking their cognitive health.

The manifest activity levels of the 1200 participants were assessed in 1986-1987. Over two decades of follow-up, 242 of the participants developed dementia, including 193 cases of Alzheimer's. Those who did referee to awful amounts of exercise had about a 40 percent reduced peril of developing any type of dementia. People with the lowest levels of physical activity were 45 percent more acceptable to develop any type of dementia than those who did the most exercise.

These trends were strongest in men. "This is the in the first place study to follow a large group of individuals for this long a period of time. It suggests that lowering the danger for dementia may be one additional benefit of maintaining at least moderate physical activity, even into the eighth decade of life," learn author Dr Zaldy Tan, of Brigham and Women's Hospital, VA Boston and Harvard Medical School, said in an Alzheimer's Association front-page news release.

The assign study found a link between vitamin D deficiency and increased risk of cognitive harm and dementia later in life. Researchers in the United Kingdom analyzed data from 3325 folk aged 65 and older who took part in the third US National Health and Nutrition Examination Survey.

The participants' vitamin D levels were reasoned from blood samples and compared with their demeanour on a measure of cognitive function that included tests of memory, orientation in time and space, and know-how to maintain attention. Those who scored in the lowest 10 percent were classified as being cognitively impaired.

The Number Of People With Dementia Increases

The Number Of People With Dementia Increases.
The tons of hoi polloi worldwide living with dementia could more than triple by 2050, a new report reveals. Currently, an estimated 44 million males and females worldwide have dementia. That number is expected to go as far as 76 million in 2030 and 135 million by 2050. Those estimates come from an Alzheimer's Disease International (ADI) procedure brief for the upcoming G8 Dementia Summit in London, England.

The projected thousand of people with dementia in 2050 is now 17 percent higher than ADI estimated in the 2009 World Alzheimer Report. The further policy brief also predicts a swerve in the worldwide distribution of dementia cases, from the richest nations to middle- and low-income countries. By 2050, 71 percent of men and women with dementia will live in middle- and low-income nations, according to the experts.

The Relationship Between Heart Disease And Dementia Exists

The Relationship Between Heart Disease And Dementia Exists.
Older women with consideration contagion might be at increased risk for dementia, according to a new study. Researchers followed nearly 6500 US women, grey 65 to 79, who had healthy brain function when the study started. Those with goodness disease were 29 percent more likely to experience mental decline over leisure than those without heart disease. The risk of mental decline was about twice as high among women who'd had a sensibility attack as it was among those who had not.

Women who had a heart bypass operation, surgery to transfer a blockage in a neck artery or peripheral artery disease also were at increased risk for mental decline. Heart infection risk factors such as high blood pressure and diabetes also increased the gamble for mental decline, but obesity did not significantly boost the risk, according to the study, which was published in the Dec 18, 2013 emergence of the Journal of the American Heart Association. "Our study provides further new testify that this relationship between heart disease and dementia does exist, especially among postmenopausal women," study founder Dr Bernhard Haring said in a journal news release.

The Same Gene Is Associated With Obesity And Dementia

The Same Gene Is Associated With Obesity And Dementia.
A deviating of the obesity-related gene FTO may distend the risk of Alzheimer's disease and dementia, finds a immature Swedish study. Previous research has shown that the FTO gene affects body legion index (BMI), levels of leptin (a hormone involved in appetite and metabolism), and the chance for diabetes. All vascular risk factors that have also been linked with the risk of Alzheimer's disease.

This late study, conducted by the Karolinska Institute in Stockholm, included more than 1000 Swedish people, age-old 75 and older, who were followed for nine years. They all underwent genetic testing at the start of the study.

Pathological Heart Rhythm Is Related To Alzheimer's Disease

Pathological Heart Rhythm Is Related To Alzheimer's Disease.
People with atrial fibrillation, a material of eccentric heart rhythm, are more likely than others to develop dementia, including Alzheimer's disease, a redone study finds. The presence of atrial fibrillation also predicted higher expiry rates in dementia patients, especially among younger patients in the rank studied, meaning under the age of 70.

So "This leaves us with the finding that atrial fibrillation, non-affiliated of everything else, is a risk factor for dementia," said Dr Gary Kennedy, chairman of geriatric psychiatry at Montefiore Medical Center in New York City. "This is adding one more block in the road toward understanding that cardiovascular disease is a major risk factor for dementia".

Now "Alzheimer's disease, in particular, is one where we don't truly understand the risk factors and what causes it, so studies counterpart this that try to investigate the causative effect will help us understand that and ultimately design therapies and approaches to hamper or minimize disease," added Dr Jared Bunch. Who are be conducive to author of a study appearing in the April edition of the HeartRhythm Journal and a cardiologist or electrophysiologist with Intermountain Medical Center in Murray, Utah.

This study, however, was not specifically set up to confirm a direct cause-and-effect relationship. The authors looked at 37025 patients without atrial fibrillation or dementia, grey 60 to 90, over a five-year period. Individuals who developed atrial fibrillation had a higher endanger of all types of dementia, even when other chance factors were taken into account. Alzheimer's disease is by far the most common coin of dementia.
