Walking slowly at 40 is a bad sign: these are your risks

How you walk it can be key to know if you are going to suffer or not some disease. The speed at which you walk predicts the risk of a person suffering from some type of condition, such as dementia, even before symptoms develop.

This is suggested by a new study that has found that the organisms and brains of people who they walk slowly they get older when they have 45 years compared to its faster counterparts.

Your lungs, teeth and immune systems also tend to be in worse condition than their peers who move faster. In addition, it is possible to identify those who will suffer from diseases in the future by mental agility tests. The findings could lead to a childhood screening program for Alzheimer's disease and other life-threatening conditions.

Young patients

The lead author, the doctor Rasmussen line, a neuroscientist at Duke University, says that "what is really surprising is that they are 45 years old, no of geriatric patients which are generally evaluated with such measures. "It is feared that one of the reasons why dementia drug trials continue to fail is that are administered too late, once the disorder has developed.

"You can detect signs of poor health in middle age with a simple test in whatever it is see how someone walks"says the expert. It was also discovered that the slowest people had a accelerated aging on a scale of 19 measures designed by the US and UK team. Surprisingly, a retrospective analysis showed that could have been selected measuring brain function when they were young children.

At three years, their IQ scores, language comprehension, tolerance for frustration, motor skills and emotional control predicted how fast they would walk 42 years later. Another of the authors, the teacher Terrie Moffitt, from King's College London, explains that "doctors know that people who walk slowly with 70 and 80 tend to die before than those who do it faster at the same age.

Childhood prevention

"This study covered the period from preschool to middle age and found that walking slowly is a symptom of health problems decades before entering the real stage of aging"says the expert. The investigation was based on a report made to 904 people born during a single year in Dunedin, New Zealand.

They were examined all their lives, until April of last year, when they were 45 years old. The analysis, published in 'JAMA Network Open', included MRI (MRI) scanners during its last evaluation. The average volume of gray and white matter, cortical thickness and brain surface area it was lower among the slowest walkers. They also had more small injuries associated with diseases in the blood vessels. In summary, their brains looked somewhat older.

In addition to suffering from dementia, the lungs, teeth and immune systems of people who walk slower tend to be worse off

They also made a panel with eight external evaluators to analyze the facial age of each participant from a photograph. The results showed that those who walked more slowly were more likely to look older than they really were. The speed of gait has long been used as a measure of health and aging in geriatric patients, but what is new is thea relative youth of the subjects and the ability to see how quickly matched the health data collected throughout their lives.

"It is a shame not to have some images monitored when they were young, but MRIs were invented when they were five and were not used in children until years later. Some of the differences in health and cognition may be linked to lifestyle choices what they have done, "the researchers explain.

The study also suggests that there are already signs in childhood of who would become the slowest walker. "We may have the opportunity to see who is going to improve your health in the future", says the expert. Without a cure for diseases such as dementia, we look for how identify those who are most at risk so they can take preventive measures before it is too late.
