If you've loved or cared for someone with Alzheimer disease, then you know it is a horrible, awful illness that leaves the patient scared and confused, and the care providers heartbroken and with few resources. A teenager may have created a valuable tool in caring for patients with Alzheimer's disease.

Alzheimer patients wandering off is a huge safety risk, but a very common occurrence in care facilities and in homes where the family is providing the care. Usually the loved one is found and returned home safe and sound, but the time spend looking can be nerve-wracking, and there is always the fear that something worse could have happened. This teen has invented a device that can help to track and notify caregivers when a patient might be roaming.

My grandfather passed away more than 10 years ago after a battle with Alzheimer's disease. It was absolutely devastating to watch him get consistently worse and not be able to do anything. This won't take away the illness -- it's not a cure -- but it's a step in the right direction, and a valuable tool for those providing care.
