The main reason for behavioral symptoms in patients suffering from Alzheimer's is the deterioration of brain cells. It causes a decline in a person’s ability to basically make sense of the world due to a slow decline in memory, thinking and reasoning skills.
The number of American’s with Alzheimer’s disease is growing each year. In 2015, an estimated 5.3 million Americans of all ages had it, according to the Alzheimer’s Association. Almost two-thirds of the patients are women.
The disease is an irreversible, progressive brain disorder that slowly destroys cognitive capabilities and eventually the ability to carry out the simplest tasks, according to the National Institute on Aging. Scientists say that damage to the brain starts as early as a decade or more before memory and other cognitive problems appear.
Once a person begins to experience greater cognitive difficulties, he or she will notice that problem solving becomes difficult and completing daily tasks takes much longer than usual.
As is the case with most health problems, every patient may experience one or more common signs in different degrees. People go through many changes, some of which are not immediately obvious.
