Relação de ELA (ALS) com exposição a radiação electromagnética

"'Jobs with relatively highe extremely low frequency electromagnetic fields levels include electric line installers, welders, sewing-machine operators, and aircraft pilots, says Vermuelen. “These are essentially jobs where workers are placed in close proximity to appliances that use a lot of electricity.”

Causal link?

The team have stressed that this study is observational – it has not proven that the fields themselves cause ALS, just that this factor is linked to a person’s likelihood of developing the disease.

However, it provides the best evidence yet that magnetic fields could be to blame for the disease. “This study has much better information on exposure to magnetic fields than previous studies,” says Pearce. “It shows that the increased risk of ALS in electrical workers is most likely due to magnetic field exposure, rather than to electrical shocks.”

But Christian Holscher, at Lancaster University, UK, says the results should be interpreted with caution. “The effect of extremely low frequency magnetic fields on ALS development is not clear,” he says. The study only just crosses the threshold for statistical significance, and because only 82 people in the analysis developed the disease, the finding may well be a false positive, he says."

"Motor neurone disease, also known as amyotrophic lateral sclerosis (ALS) is a rare condition that progressively damages parts of the nervous system.

it is also known as Lou Gehrig's disease after the condition was named after the US baseball player when he was diagnosed in 1939 at just 36 years old.

It occurs when specialist nerve cells in the brain and spinal cord called motor neurones stop working properly - known as neurodegeneration.

Life expectancy for about half of those with the condition is three years from the start of symptoms.

However, some people may live for up to 10 years, and in rarer circumstances even longer.

The condition can affect adults of all ages, including teenagers, although this is extremely rare.

It's usually diagnosed in people over 40, but most people with the condition first develop symptoms in their 60s. It affects slightly more men than women.

There's currently no cure for motor neurone disease.

Treatment aims to make the person feel comfortable and have the best quality of life possible

It also tries to compensate for the progressive loss of bodily functions such as mobility, communication, swallowing and breathing."
