Alzheimer’s disease affects millions of people around the world. American researchers say the disease will affect more than one hundred million people worldwide by the year twenty fifty. That would be four times the current number. Researchers and doctors have been studying Alzheimer's patients for a century. Yet the cause and cure for the mental sickness are still unknown. However, some researchers have made important steps towards understanding it. Several early signs of the disease involve memory and thought processes. At first, patients have trouble remembering little things. Later, they have trouble remembering more important things, such as the names of their children. Itchy skin is a common problem. Severe itching can interfere with sleep or lead to
painful damage from scratching. Now, scientists may have a way to develop new treatments for severe itching. They report finding a gene that sends the itch signal up the spinal cord to the brain. This is the first gene identified for the itch sensation in the central nervous system. A team led by Zhou-Feng Chen at Washington University School of Medicine in Saint Louis, Missouri, made the discovery in mice. The study appeared last week in the journal Nature. The gene is called GRPR, for gastrin-releasing peptide receptor. This gene has been studied for years, but scientists did not know it was linked to itching. The Washington University researchers say they discovered the connection by accident while searching for genes linked to pain. The retina is the sensory tissue in the back part of the eye. It gathers light
and captures images from the lens, much like film in a camera. The retina processes these images into signals that travel through the optic nerve to the brain. Diseases of the retina can cause vision loss over time. A thirty-year-old listener in Vietnam says he cannot see well and doctors have told him he has retinal degeneration. This is the loss or destruction of the sensory tissue of the retina. Trinh Phuong Bac says he first developed problems in his right eye when he was a child. He would like to know more about this disease. Doctor Emily Chew is a deputy division director at the National Eye Institute, one of the National Institutes of Health in the United States. She says it is true what doctors have told our listener: there is no cure for retinal degeneration.
