Depending on how old you are you could be developing alzheimer’s disease.

Alzheimer’s is a degenerative and terminal disease for which there is currently no known cure. In its most common form, it occurs in people over 65 years old although a less-prevalent early-onset form also exists.

The disease can begin many years before it is eventually diagnosed. In its early stages, short-term memory loss is the most common symptom, often initially thought to be caused by aging or stress by the sufferer.

Later symptoms include confusion, anger, mood swings, language breakdown, long-term memory loss, and the general withdrawal of the sufferer as his or her senses decline.

Gradually the sufferer loses minor, and then major bodily functions, until death occurs. Although the symptoms are common, each individual experiences the symptoms in unique ways.The duration of the disease is estimated as being between 5 and 20 years.
