Aging

If you can't balance on one leg for 20 seconds you are more likely to have small blood vessel damage in the brain and reduced cognitive function, even if you otherwise seem healthy, according to new research in Stroke.

The study consisted of 841 women and 546 men, average age of 67. To measure one-leg standing time, participants stood with their eyes open and raised one leg. The maximum time for keeping the leg raised was 60 seconds. Participants performed this examination twice and the better of the two times was used in the study analysis. Cerebral small vessel disease was evaluated using brain magnetic resonance imaging.


You should not be surprised by the irregularity of a newborn infant's sleep patterns but by the age of six months, if the baby is not sleeping through the night, many parents wonder if something is wrong with their baby or their sleeping arrangements.

It helps parents to understand that "normal" sleep patterns for a child are somewhat broad, according to a new paper.


For some Medicare patients, the prognosis was better when cardiologists were away from the hospital attending national cardiology meetings.

Anupam B. Jena, M.D., Ph.D., of Harvard Medical School, Boston, and coauthors analyzed differences in 30-day mortality and treatment such as angioplasty (also known as percutaneous coronary intervention, PCI) among Medicare patients hospitalized for heart attack (acute myocardial infarction, AMI), heart failure or cardiac arrest from 2002 to 2011 during the dates of two national cardiology meetings compared with identical non-meeting dates in the three weeks before and after conferences.  


Scam artists often prey on older people and that has fed the perception that when it comes to important financial decisions, getting old means having less competence.

Not so, according to new work using credit scores and cognitive ability tests, which instead found evidence that "crystallized intelligence" - gained through experience and accumulated knowledge - is more important that "fluid intelligence," the ability to think logically and process new information.

Past research has found that fluid intelligence decreases with old age and so being a senior citizen means being resigned to "cognitive decline."
Scientists have demonstrated that mobility can be restored in patients with Parkinson's disease, the major degenerative disease of the motor system worldwide. 

The experiments used stem cells to generate dopaminergic nerve cells and reactivate the production of dopamine in the brains of rats with symptoms of shaking palsy or Parkinson's disease. 

Though deaths due to drug use and hepatitis C have gone up, falling death rates due to cancer and heart disease have resulted in a global life expectancy increase of 5.8 years in men and 6.6 years in women between 1990 and 2013, according to an analysis from the Global Burden of Disease Study 2013 (GBD 2013).

In high-income regions, falling death rates from most cancers (down by 15%) and cardiovascular diseases (down by 22%) have increased life expectancy, while rapidly declining death rates for diarrhea, lower respiratory tract infections, and neonatal disorders have helped extend life expectancy in low-income countries (see figure 7 page 14, and table 2 pages 15-23). 


A new study says that delaying the cutting of the umbilical cord in newborns by two minutes leads to a better development of the baby during the first days of life - by influencing the resistance to oxidative stress in newborns. 


Some people just age better than others and it is isn't due to lifestyle. Most centenarians smoked cigarettes at one point, many were obese and almost all eat red meat. 

Perhaps birds can tell us what really matters. 


Epidemiologists have examined the relationship between body weight and life expectancy and say that overweight and obese individuals have the potential to decrease life expectancy by up to 8 years.

If diabetes or cardiovascular disease develop, that could shorten life expectancy ever more, according to their analysis of data from the National Health and Nutrition Examination Survey (years 2003 to 2010) which was used to estimate the annual risk of diabetes and cardiovascular disease in adults with different body weights.

The data from almost 4,000 individuals was also used to analyze the contribution of excess body weight to years of life lost and healthy years of life lost. 


Drinking 3-5 cups of coffee per day has been linked to protection against Alzheimer's Disease, according to a new review of studies.

The number of people in Europe aged over 65 is predicted to rise from 15.4% of the population to 22.4% by 2025 and, with an aging population, neurodegenerative diseases such as Alzheimer's Disease are of increasing concern.  Alzheimer's Disease affects one person in twenty over the age of 65, amounting to 26 million people world-wide.

Epidemiologists have linked regular, moderate coffee consumption with a possible reduced risk of developing Alzheimer's Disease. An overview of the findings were presented during a satellite symposium at the 2014 Alzhemier Europe Annual Congress.
