GRAHAM: "Tuscon Medical Centre researchers have developed a method of detecting partial blockages of the arteries leading to the brain.
"The procedure consists of two tests, which take less than fifteen minutes. In the first, a microphone is placed on the neck, and the sound of blood rushing through the carotid arteries is recorded on tape ... and photographed on a oscilloscope. The difference between normal and partially blocked arteries is often dramatic.
"The second part of the test is called oculoplethysmography. The patient has sensitive detectors clipped to his ears, and two probes much like contact lenses are inserted in the eyes. It looks uncomfortable, but special drops deaden the eyes, and the patient actually feels a pulse at the surface of the eye. Since the eyes are supplied by the same artery as the brain, and the ears are fed through a different branch, if a patient has normal arteries ... the pulse at the eyes and the cars occurs practically at the same instant. If there is a blockage, the pulse at the eyes will be a lightly delayed.
"By analysing the sensor recordings, doctors can determine which arteries are blocked ... and to a great degree ... how severely. The procedure is reported to be ninety percent accurate in diagnosing restrictions of arteries leading to the brain. With early deletion, many of the blockages can be cleared with medication or surgery before they can cause a stroke."

Background: In the Western world, strokes are a leading cause of death. In the United States alone, they account for one-third of all deaths.
Strokes occur when the blood supply to the brain is cut off. Following intensive research, the staff at the Tuscon Medical Centre in the United States has developed a method of predicting when a patient is likely to have a stroke. If the patient is treated promptly, a stroke can be prevented with the now medical breakthrough.
The medical centre can now detect partial blockages of the arteries leading to the brain.
With two short tests, the patient can know if he is likely to have a stroke, and be treated accordingly.
Since the discovery the centre has been named one of ten winners of an American award, the Geraod Lambert Medical Award, for innovative or imaginative ideas designed to improve patient care and reduce health costs.
