CAN INJECTIONS OF YOUNG BLOOD REVERSE AGING?

It sounds like something from a sci-fi movie: injecting blood from a young person into an aging, Alzheimer’s patient, and watching as renewed youth is awakened. But that’s exactly the outcome realized in studies of mice, which showed astounding brain cell growth in the area of the brain critical to memory and learning—the hippocampus. Perhaps just as incredible was the effect on the brains of the younger mice who received injections of older mouse blood, resulting in stunted neuron growth.

The first human trial is already underway on Alzheimer’s patients, led by Tony Wyss-Coray, neurology professor at the Stanford School of Medicine, with results expected by the end of the year. But what will the impact be if the study proves that young blood does reverse aging in humans? Practical applications may involve short periods of infusions to help older patients heal faster after a surgery, but there are many fears about the unknown impact of interfering with the body’s natural aging process.
