Imagine your grandmother, who had been taking care of you ever since you were a child, has just been diagnosed with Alzheimer's disease. You visit her often and talk about the many times you've spent together having fun. She nods and smiles back at you after every story, but secretly, you know she has no recollection of those moments. Slowly, she even starts to forget your name.
Now, imagine we are in the future. Medical technology has advanced to the point where diseases are no longer a problem to anyone anymore. An invention has been created to target the plaques and tangles found between nerve cells that are the source of the abnormal brain cell deaths in patients with Alzheimer’s disease. Once Alzheimer’s disease has been detected at an early stage, using technology already found in modern day, the patient will be injected with a modified version of macrophages. Instead of targeting viruses or bacteria, these modified macrophages will only engulf the plaques and tangles that are causing Alzheimer’s disease. Designed to be a lot smaller than normal macrophages, this version will be capable of navigating around the brain easily, protecting healthy nerve cells. With this invention, people who are diagnosed with Alzheimer’s disease will not have to worry about the symptoms of memory loss and decline in thinking skills.
