Researchers at the Massachusetts Institute of Technology (MIT) have created a program able to detect accurately and automated various cognitive disorders. A useful tool for the early diagnosis of diseases such as Alzheimer tool.

Various cognitive disorders such as Parkinson's or Alzheimer's begin long before become apparent in everyday life, that is why early detection of these disorders on time would improve the living conditions of those affected.

For this, the researchers used data collected in the Lahey Hospital, a doctor outside of Boston, who for nine years performing the test clock using a digital pen that captures the computer drawings by heart patients, in addition to recording the process of creating them with great precision.

In the test, the patient should watch draw a clock that should mark a certain time, and also to copy one already drawn. The observation of changes in how these drawings allows physicians to identify signs of deterioration in the patient's brain.

Thus the data obtained with a computer program that can automatically interpret and evaluate the test clock, increasing accuracy and eliminating the subjectivity of an evaluation by humans think.

"We have improved the analysis, so that is automatic and objective. 

With the right equipment you can get a faster and more accurate result, "said Cynthia Rudin, responsible for research. The different patterns revealed for example that it is normal for healthy adults spend more time thinking drawing, when the memory is affected, the cooling off period is extended.

Moreover, in the case of Parkinson's patients tend to need more time to draw the clocks, in turn, they tend to be smaller, suggesting that it is costing them a greater effort to perform the task. These considerations could be overlooked in the traditional test because, in many cases, the doctor can not see in detail how the patient performs the drawing, but only the final result.

This work will not only better diagnose a number of very serious for those who suffer pathologies, but also offers an advance in automating processes that can be tedious and inefficient when performed by humans.

Now scientists are working on developing a system that can easily be implemented in hospitals and health centers.

finally, I would like to say thanks you for reading this article and you can read more at here
