Study finds Alzheimer’s spreads like infection

A new US study has found that Alzheimer’s disease spreads from one part of the brain to another like an infection, a discovery that could aid the development of treatments to slow its progress.

The Columbia University Medical Center (CUMC) study on transgenic mice found that the abnormal tau protein linked to the disease travels along brain circuits, “jumping” from neuron to neuron.

The findings, published Wednesday in the online journal PloS One, could one day help researchers develop treatments to slow or halt the progression of the disease, which causes increasingly severe dementia.
