Doctors Win A Battle In Alzheimer's Disease

A day is forgotten keys, other people or things, or get to a place and can not remember what it was looking for, suggesting the individual that is losing memory name. Which is due to decline by age or illness depends on, say doctors, to certain conditions that are developed in our brain, long before the symptoms of this evil known by the name of the ad appear.

A group of scientists has just announced in Washington that a subtle change in the region to produce memory allows you to predict who will suffer Alzheimer, nine years before they are observed signals. Doctors hope that this would help them to one day prevent evil to develop.

Researchers followed 53 persons aged middle-aged and older who were still healthy, for 24 years. Noting that a lower energy use in a part of the brain called hippocampus had correctly pointed out in 85% of patients who have Alzheimer's or any other condition that would affect your memory.

The Dr. Lisa Mosconi, from New York University, Director of research, said: "we have found the main point of prognosis and it seems that the hippocampus is the first region in the brain that is affected by Alzheimer's disease". The hippocampus is a Horseshoe that occupies the external wall of each lateral ventricle of the brain and is located next to the temples.

Alzheimer's disease to the brain cells die, produce devastating symptoms. The former tend to be the gradual loss of memory and brain damage progresses, patients lose orientation, have difficulties to speak, use tools, objects, and even their own members.

One of the theories of scientists that kills brain cells is beta amyloid, abnormal protein forming sticky entanglements that accumulate in the brain - generally known as plates.

Alzheimer's disease affects already at 4.5 million people already approximately 27.7 million people in the world, but it is estimated that only in this country the number of affected could reach 14 million by 2050. This is assuming that he is not achieved to intervene with prevention, which is what ultimately systems attempt to scientists today.

The risk of developing Alzheimer's disease increases with age. According to Dr. Small, at age 65 is 5%, 30% to 40% 75y to 80. Not always the condition known as "dementia", in which the individual loses his cognitive functions, caused by Alzheimer's disease, because the definition encompasses other conditions, such as for example, the strokes.

In the past only knew with certainty dealing with Alzheimer's disease when after his death the patient was an autopsy. But today, neuroscientists made some scans known as CT scans that make diagnosis in life (PET) positron emission.

The absence, however, a cure against Alzheimer's disease, poses a dilemma on the establishment of early Diagnostics. The international meeting in Washington, the Australian doctor Henry Brodaty, asking: "Is ethical to do exploration to discover an evil that we do not have cure?"

Prevention:
Dr. Gary Small, director of the Centre on ageing at the University of California Los Angeles (UCLA), feels great the possibility of knowing in advance the future development of Alzheimer's disease.

"The diagnosis early is the right approach, you can help find ways to prevent this disease", says. "Cadavez there more medicines, and some of them serve to avoid accumulation of amyloid beta".

"One of the things that increases the likelihood of developing Alzheimer's disease and suffering from memory loss in general is stress, Gary Small, author of the book called the Bible memory." "" In it, explains inter alia how combat stress, because "Although you cannot remove altogether, can be reduced".

Recommends staying physically and mentally active to fight against degeneration of nerve cells and controlling blood pressure.

Meeting on the prevention of Alzheimer's disease also presented the results of studies showing that certain habits helped protect the brain diseases. It was found that people taking fruit or vegetable juice three times a week, at least, were less prone to Alzheimer's disease, as also were those who ate high doses of folic acid.

"Every time is more we can do", insists Gary Small. "And in the next 10 years," predicts, "be produced important advances in the fight against Alzheimer's disease".the opinion
