MRI scan before the symptoms of dementia risk prediction: Examination



IR research in the brain prevents an individual from developing dementia in the next three years, before the symptoms of the disorder appear, scientists have found it.

Researchers from the University of Washington and University of California, San Francisco, used magnetic resonance imaging (MRI) brain scanners to predict dementia with an accuracy of 89 percent.

The discovery suggests that doctors may use available tests one day, and there is a risk of developing dementia that may lead to death symptoms.

"Right now, it's hard to know that conventional elderly or mild cognitive disorder develops dementia," said Cyrus A Raji, a professor at the University of Washington.

"A single MRI scanning predicts a 2.2-year average dementia, in general, in the case of a clinically detectable memory loss, for doctors to advise and care for their patients," said Raji.

Although Alzheimer's disease is not yet able to prevent or delay the onset of disease, still identifying people who are still at risk of developing dementia may still be beneficial, the researchers said.

People can make decisions while financial and lifestyle decisions remain the full control of their capabilities.

Researchers study MRI studies to make physical signs of cognitive imin.

They used a technique called Tensor Differences to assess the health of the white matter of the brain, including those that are capable of talking to different brain sections.

"The Tension Diffusion image is a way of measuring water molecular motion through white matter," Rajik said.

"If water molecules are not commonly moving, it suggests underlying science damage to emphasize cognition problems," he said.

Alzheimer's Disease The Neuroimaging Initiative is a set of collaborations that combines data, financing and expertise to improve Alzheimer's disease clinical trials. Researchers have identified cognitive disorders with more than 10 years of age and who, according to age and gender, maintain 10-percent thinking skills.

The average age of the two groups was 73. Subsequently, the researchers examined the expansion tension of the MRI that took place before the two-year period of more than 20 years.

The researchers found that people with cognitive decline had a great effect on their white matter.

The researchers studied a separate sample of 61 people using a more refined measure of white matter.

With this new analysis, the brain was able to predict the cognitive concern predicted by percentile accuracy. When the researchers showed the damage to the specific sections of the brain, the accuracy rose to 95 percent.

"Let us suppose that people who develop dementia can say that they have these differences in MRI of diffusion, compared to the normal scans of people of one and the same complexity.
