[New treatment is expected to enhance the brain's ability to remove waste and may be used to prevent dementia] On November 9, a research team from the University of Oulu in Finland developed a new treatment that is expected to enhance the brain's ability to remove waste and promote the excretion of harmful proteins while the human body is awake. This provides new ideas for the prevention and treatment of neurodegenerative diseases such as Alzheimer's disease. The researchers believe that if the brain's clearing capabilities can be safely enhanced in the future while people are still healthy, it may be possible to prevent neurodegenerative diseases such as Alzheimer's disease, or at least slow their progression. However, this therapy has only been initially evaluated in healthy adults, and its efficacy cannot yet be confirmed. The research team plans to conduct further studies to evaluate the potential of this method in the prevention and treatment of related diseases. Relevant research papers have been published in the British journal Nature Communications.
