People living near a steel plant or other source of manganese emissions have increased risk of developing Parkinson’s. One million Americans live with the degenerative disease, according to the Parkinson’s Disease Foundation. Farm pesticides increase the chance of developing it, but little is known about the effects of urban life.

“The environmental risk factors of Parkinson’s are relatively understudied, particularly in cities, where the vast majority of patients with Parkinson’s, said by e-mail Dr. Brad A. Racette, School of Medicine at Washington University in St. Louis, Missouri.

Racette’s team analyzed data from 5 million Medicare beneficiaries had not moved from county between 1995 and 2003. They then compared the number of cases of Parkinson industrial emissions of copper, lead and manganese obtained from the Environmental Protection Agency.

By 2003, less than 1 percent of city dwellers had Parkinson’s. In counties with low or no emission of metals, 274, 100,000 residents had the disease, compared with 489 residents in counties with high levels of manganese. The risk remained high after accounting for age, sex and ethnicity, published in the American Journal of Epidemiology. In areas with high levels of copper releases also reported more cases of Parkinson’s, but this increase was so slight that it could be attributed to chance.

The team known whether manganese actually made ​​more people develop Parkinson’s. It is possible that in counties with high emissions of manganese influenced other risk factors.

There are about 600 diseases that affect the brain. And it is striking that those who are more dangerous to our brain that tell us more. Parkinson, for example, takes 18,000 lives each year. This disease has taught us how the brain controls our body.

Knowledge of the mechanisms of memory are clear in Alzheimer’s disease. And by stroke researchers learned to keep isolated the damaged brain cells. In the most serious diseases are the best opportunities for science.

Neurological diseases are those in which an injury or dysfunction of the nervous system, either central or peripheral.  If we make a comparison with computing, neurological diseases would be a hardware problem, machinery, and psychiatric would rather the software, the system program.

Neurologists often have patients with diseases which can detect lesions in the central nervous system, such as vascular brain, which is a dysfunction of neurotransmitters such as Parkinson Sea.

Perhaps one of the most prominent pathology is the stroke, also known as brain circulatory disease or cerebrovascular accident (CVA) before misnamed cerebral atherosclerosis.

This is a neurological disease that occurs most often disabling or fatal consequences, although many things you can do to avoid them.

Everyone knows what a heart attack, but what a brain infarction. Myocardial infarction or heart is a matter of urgent consultations everywhere and people know what it is.

Myocardial ischemia and brain are less known. Occurs anywhere in the body including the brain, where lack of circulation and oxygen can not reach.

Cerebral artery is covered and the most common failure is that the functioning of the body part that depends on the cerebral artery. The brain is organized as a map, so that failure of the movement in a particular area, that will speak with the failure of such a function linked to a body part.

What we know everyone is hemiplegia, which occurs when you flip one of the major cerebral arteries.  They are conditions that may be transient, with recovery and may even be reversed, so the patient must make a query quickly, because once installed it is more difficult to overcome.
