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.

Many Women In The First Year After Menopause Deteriorating Memory And Fine Motor Skills
Many Women In The First Year After Menopause Deteriorating Memory And Fine Motor Skills.
Women growing through menopause occasionally give the impression they are off their mental game, forgetting phone numbers and passwords, or struggling to find a particular word. It can be frustrating, baffling and worrisome, but a small new study helps to explain the struggle. Researchers found that women in the initially year after menopause perform slightly worse on certain mentally ill tests than do those who are approaching their post-reproductive years. "This study shows, as have others, that there are cognitive cognitive declines that are real, statistically significant and clinically significant," said study author Miriam Weber, an helpmeet professor in the department of neurology at the University of Rochester in Rochester, NY "These are remote declines in performance, so women aren't becoming globally impaired and unable to function. But you cognizance it on a daily basis".
The study is published in the current issue of the journal Menopause. According to the researchers, the technique of learning, retaining and applying new information is associated with regions of the discernment that are rich in estrogen receptors. The natural fluctuation of the hormone estrogen during menopause seems to be linked to problems associated with ratiocinative and memory. "We found the problem is not related to absolute hormone levels. Estrogen declines in the transition, but before it falls, there are theatrical fluctuations".
Weber explained that it is the variation in estrogen constant that most likely plays a critical role in creating the memory problems many women experience. As the body readjusts to the changes in hormonal levels on a future occasion after a woman's period stops, the researchers shady mental challenges diminish. While Weber said it is important that women gather from that memory issues associated with menopause are most likely normal and temporary, the study did not include women whose periods had stopped for longer than one year. Weber added that she plans to pinpoint more exactly how long-term recollection and thinking problems persist in a future study.
Other research has offered conflicting conclusions about the rational changes associated with menopause, the study authors wrote. The Chicago spot of the Study of Women's Health Across the Nation (SWAN) initially found no relation between what stage of menopause women were in and how they performed on tests of working homage or perceptual speed. However, a different SWAN mull over identified deficits in memory and processing speed in the late menopausal stage.
Studies of menopause typically characterize distinct stages of menopause, although researchers may differ in where they draw the line between those transitions. The researchers tortuous with this study said that the variation in findings between studies may be due to different ways of staging menopause.

Hypothyroidism Affects The Brain
Hypothyroidism Affects The Brain.
Hypothyroidism, a form that causes low or no thyroid hormone production, is not linked to submissive dementia or impaired brain function, a new investigation suggests. Although more research is needed, the scientists said their findings add to mounting ground that the thyroid gland disorder is not tied to the memory and thinking problems known as "mild cognitive impairment". Some ex evidence has suggested that changes in the body's endocrine system, including thyroid function, might be linked to Alzheimer's blight and other forms of dementia, said researchers led by Dr Ajay Parsaik, of the University of Texas Medical School in Houston.
Mild cognitive impairment, in particular, is cogitation to be an cock's-crow warning sign of the memory-robbing disorder Alzheimer's disease, the scrutinize authors said in a university news release. In conducting the study, Parsaik's group examined a group of more than 1900 people, including those with mild and more severe cases of hypothyroidism. The participants, who were from the same Minnesota county, were between 70 and 89 years of age.

Risk Factors For Alzheimer's Disease
Risk Factors For Alzheimer's Disease.
Older adults with homage problems and a narration of concussion have more buildup of Alzheimer's disease-associated plaques in the brain than those who also had concussions but don't have respect problems, according to a new study. "What we think it suggests is, head trauma is associated with Alzheimer's-type dementia - it's a endanger factor," said study researcher Michelle Mielke, an friend professor of epidemiology and neurology at Mayo Clinic Rochester. But it doesn't degenerate someone with head trauma is automatically going to develop Alzheimer's. Her turn over is published online Dec 26, 2013 and in the Jan 7, 2014 print version of the journal Neurology.
Previous studies looking at whether head trauma is a risk factor for Alzheimer's have come up with conflicting results. And Mielke stressed that she has found only a relate or association, not a cause-and-effect relationship. In the study, Mielke and her band evaluated 448 residents of Olmsted County, Minn, who had no signs of tribute problems.
They also evaluated another 141 residents with memory and thinking problems known as mild cognitive impairment. More than 5 million Americans have Alzheimer's disease, according to the Alzheimer's Association. Plaques are deposits of a protein scrap known as beta-amyloid that can erect up in between the brain's nerve cells. While most folk develop some with age, those who develop Alzheimer's generally get many more, according to the Alzheimer's Association.
They also minister to to get them in a predictable pattern, starting in brain areas crucial for memory. In the Mayo study, all participants were venerable 70 or older. The participants reported if they ever had a brain injury that implicated loss of consciousness or memory. Of the 448 without any memory problems, 17 percent had reported a cognition injury. Of the 141 with memory problems, 18 percent did.

Doctors Discovered How The Brain Dies
Doctors Discovered How The Brain Dies.
Shrunken structures privy the brains of unmanageable marijuana users might explain the stereotype of the "pothead," brain researchers report. Northwestern University scientists studying teens who were marijuana smokers or departed smokers found that parts of the mastermind related to working memory appeared diminished in size - changes that coincided with the teens' under par performance on memory tasks. "We observed that the shapes of brain structures connected to short-term memory seemed to collapse inward or shrink in people who had a history of circadian marijuana use when compared to healthy participants," said study author Matthew Smith.
He is an subordinate research professor in psychiatry and behavioral sciences at the Northwestern University Feinberg School of Medicine, in Chicago. The shrinking of these structures appeared to be more advanced in common people who had started using marijuana at a younger age. This suggests that youngsters might be more influenceable to drug-related memory loss, according to the study, which was published in the Dec 16. 2013 descendant of the journal Schizophrenia Bulletin.
So "The brain abnormalities we're observing are anon related to poor short-term memory performance. The more that capacity looks abnormal, the poorer they're doing on memory tests". The paper is provocative because the participants had not been using marijuana for a duo years, indicating that memory problems might persist even if the person quits smoking the drug, said Dr Frances Levin, chairman of the American Psychiatric Association's Council on Addiction Psychiatry. At the same time, Levin cautioned that the line presents a chicken-or-egg problem.
It's not explicit whether marijuana use caused the remembrance problems or people with memory problems tended to use marijuana. "The big $64000 examine is whether these memory problems predate the marijuana use". The swotting focused on nearly 100 participants sorted into four groups: healthy people who never used pot, tonic people who were former heavy pot smokers, people with schizophrenia who never used pan and schizophrenics who were former heavy pot users. Researchers used MRI scans to meditate on the structure of participants' brains.

New Solutions For The Prevention Of Memory Loss From Multiple Sclerosis
New Solutions For The Prevention Of Memory Loss From Multiple Sclerosis.
Being mentally working may domestic reduce memory and learning problems that often crop up in people with multiple sclerosis, a new study suggests. It included 44 people, about majority 45, who'd had MS for an average of 11 years. Even if they had higher levels of capacity damage, those with a mentally active lifestyle had better scores on tests of learning and reminiscence than those with less intellectually enriching lifestyles. "Many people with MS struggle with learning and memory problems," work author James Sumowski, of the Kessler Foundation Research Center in West Orange, NJ, said in an American Academy of Neurology news programme release.
So "This study shows that a mentally strenuous lifestyle might reduce the harmful effects of brain damage on learning and memory". "Learning and homage ability remained quite good in people with enriching lifestyles, even if they had a lot of imagination damage brain atrophy as shown on brain scans ," Sumowski continued. "In contrast, persons with lesser mentally acting lifestyles were more likely to suffer learning and memory problems, even at milder levels of knowledge damage".
Sumowski said the "findings suggest that enriching activities may build a person's 'cognitive reserve,' which can be meditation of as a buffer against disease-related memory impairment. Differences in cognitive standoffishness among persons with MS may explain why some persons suffer memory problems early in the disease, while others do not bloom memory problems until much later, if at all".
The study appears in the June 15 question of Neurology. In an editorial accompanying the study, Peter Arnett of Penn State University wrote that "more investigation is needed before any firm recommendations can be made," but that it seemed within reason to encourage people with MS to get involved with mentally challenging activities that might improve their cognitive reserve.
What is Multiple Sclerosis? An unpredictable cancer of the central nervous system, multiple sclerosis (MS) can series from relatively benign to somewhat disabling to devastating, as communication between the brain and other parts of the body is disrupted. Many investigators feel MS to be an autoimmune disease - one in which the body, through its safe system, launches a defensive attack against its own tissues. In the case of MS, it is the nerve-insulating myelin that comes under assault. Such assaults may be linked to an mysterious environmental trigger, it may be a virus.
Most people experience their first symptoms of MS between the ages of 20 and 40; the opening symptom of MS is often blurred or double vision, red-green color distortion, or even blindness in one eye. Most MS patients participation muscle weakness in their extremities and difficulty with coordination and balance. These symptoms may be unembroidered enough to impair walking or even standing. In the worst cases, MS can exhibit partial or complete paralysis.
