The development of Alzheimer's as a contagious disease

The findings of scientists from Columbia University Medical Center (USA) have published in online magazine PloS One that Alzheimer's disease spreads from one part of the brain to other parts around brain as a form of infection.

Scientists have studied and injected a small part of the brain of mice with Alzheimer's disease into the brains of healthy mice so that specific Alzheimer's protein fibers disperse in the mouse's brain to heal . like the way of transmission or bacteria. They found that the protein called "Tau " anomaly associated with this Alzheimer's disease moves along the brain's nervous system, then jumps from one neuron to another.

Previous studies have also suggested that the disease begins in the cerebral cortex, the part that plays an important role in memory, before they spread to other important areas associated with more advanced brain function.

Alzheimer's disease is a common form of dementia, characterized by the accumulation of specific proteins, which can infect themselves as bacteria, in brain neurons called neurons.

The disease cannot be prevented and treated thoroughly, but with this new discovery researchers hope to open up a prospect in therapeutic therapies to inhibit or delay the development of inherent disease. causes severe dementia in humans.

According to neuroscience professor Scott Small and co-researcher, the best treatment for Alzheimer's disease is similar to cancer, which is to discover and conduct treatment right away. the first part, to inhibit the development of the disease.

According to the Alzheimer's Association, an estimated 5.4 million cases and illnesses are also the sixth highest cause of death in the United States.
