In the United States, there are over six million dementia patients, and early detection and medication initiation can slow down the progression of the disease. However, traditional brain diagnostic examinations are costly. Medical experts have discovered that a new blood testing technology can detect dementia at an earlier stage. In the U.S., there is also new research using extensive pathology images to train artificial intelligence, which can accurately detect prostate and breast cancers. A recent report suggests a startling trend: cancer in the U.S. is getting younger, with a significant increase in patients under 50. Ohio State University is developing a new system that uses artificial intelligence trained on a large dataset of cancer patient pathology data to interpret pathology images and detect cancer. In the early stages, this technology shows significant accuracy in detecting prostate and breast cancers. The technology is currently in the clinical trial phase and could be applied in as soon as three years.
A recent study published in the Journal of the American Medical Association Neurology indicates a promising future for the detection of Alzheimer's disease through blood tests. The study reports that a commercially available blood test tool, pTau217, developed by ALZpath, can accurately identify the "key features" of Alzheimer's disease. This tool can precisely recognize tau proteins and beta-amyloid proteins associated with Alzheimer's. Tau is a protein linked to the accumulation of toxic substances in the brain, while beta-amyloid plaques accumulate in the brain. Although not everyone with elevated tau and abnormal beta-amyloid concentrations will develop Alzheimer's, this type of test is deemed suitable for pre-dementia screening. According to Richard Isaacson, the director of research at the Florida Alzheimer's Disease Research Institute, "Tests like these are appropriate to be conducted before cognitive symptoms appear. By tracking the concentrations of these proteins over the long term, we can better control Alzheimer's disease."
