 Did you know nuclear medicine can help diagnose Alzheimer's disease? Alzheimer is a type of dementia that will affect the memory, the behavior, and the capability of the people to understand. The disease was first described in 1906 by the German psychiatrist Alois Alzheimer. Since then, scientists have been trying to understand it. Through molecular imaging, the IAEA is helping doctors to diagnose Alzheimer's at a very early stage. If we have access to the brain imaging for which we need the IAEA, we can actually diagnose it even sooner and we can use it as a preventive measure. There is no cure for Alzheimer's disease, but early diagnosis can help delay its progression and allow patients to receive the appropriate medical treatment. When a patient actually comes to the clinic with dementia symptoms, there are already many, many neurons that are lost in the brain, so it's very hard to treat those patients. So if you can detect disease in the very early stage, more likely that we can actually guide the patient to the possible right treatment. The IAEA supports member states by training nuclear physicians and technologists in molecular imaging. This nuclear technique provides detailed pictures of what is happening inside the brain. So to image human brain, we have to provide radiopharmaceuticals, we have to provide scanners, and all of those need to be well coordinated and implemented well to really achieve high quality of images. Diagnostic imaging plays a vital role in the lives of many people suffering from dementia around the world.
