For years, experts have been trying hard to unravel the secrets behind Alzheimer's disease. Hoping to prevent the disease before it could develop, researchers have been trying their best to pinpoint the specifics of the disease.

In a recent update, new information has been added to the database of the disease. Based on a UK-based research, losing one's ability to navigate through a familiar route could be an early sign of the disease.

"Alzheimer's is considered to be a disease of memory but we now think of our early work that the difficulty people are really having - at least to begin with - is not to do with declining memories but to do with their declining ability to visualize the location of objects or themselves. They are losing their ability to navigate," The Guardian quoted researcher Karen Ritchie saying.

There are other early signs of Alzheimer's disease to consider. The most common symptom is memory loss, according to WebMD.

In some cases, early signs of Alzheimer's disease include having issues with problem-solving and planning. Since mental deterioration is gradually setting in, an individual may have a hard time to concentrate on detailed tasks, especially involving numbers.

Changes and vision could also be a sign of the disease. It would get harder to read words on a page, or one may experience difficulty judging distance. This symptom is usually accompanied by time and place disorientation.

The symptoms mentioned above are just some of the early signs of Alzheimer's disease. If you are experiencing any of the above symptoms, consult an expert immediately.
