According to the National Institute of Aging, “Alzheimer’s disease is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills, and eventually the ability to carry out the simplest tasks,” (Fact). Alzheimer’s disease is the most common form of dementia (Association). It causes disturbances in metabolic processes that are vital to keeping neurons healthy. These disturbances cause nerve cells to stop working, lose connection with other nerve cells, and eventually die. This causes memory loss, behavioral issues and problems with critical thinking (Fact).
Causes
Amyloid plaques are essential when it comes to Alzheimer 's disease. Plaques are abnormal clusters of protein fibers between the nerve cells, as seen

This disease disrupts very important processes that the nerve cells must carry out in order to survive, including communication, metabolism, and repair. At first, the disease impair nerve cells and their communication in the parts of the brain that are involved in memory. Eventually, the disease destroys the parts of the brain that deal with language, social behavior and reasoning. Afterwards, more and more parts of the brain become damaged and the person becomes unresponsive to the outside world.
Stages
Alzheimer’s disease happens in three stages; mild, moderate and severe as seen in figure 4. During the first stage, mild, the patient may be able to be on their own. Function as normal, doing simple tasks such as driving, working and socializing. During this stage, plaques and tangles begin to form, but no symptoms can be detected. They begin to form in areas of the brain that are responsible for learning and memory and thinking and planning. This can cause confusion and trouble expressing and organizing thoughts.
The next stage is the moderate stage. This is the longest stage of the three. Plaques and tangles spread to areas involved in speaking and understanding speech and perceptions. During this stage, the patient begins acting out, getting frustrated, acting in unexpected ways and confusing words. This is where most patients are
