The symptoms of Alzheimer's disease often come on slowly. It might start when someone has trouble recalling things that just happened or putting thoughts into words. But over time, the problems get worse. People in the later stages of the disease usually can’t live alone or care for themselves.
There are three main phases of Alzheimer's: mild, moderate, and severe. Each stage has its own set of symptoms.
A doctor can check on these symptoms and do tests to know if a person has Alzheimer’s or something else.
This is when memory loss gets worse and starts to cause problems in daily life. This stage can last from 2 to 10 years.
Someone with moderate Alzheimer's may start to forget details about his life, like where he went to high school or when he got married. He may not recognize or remember family members and friends. He might also forget where he leaves things and can’t retrace his steps to find them.
Other symptoms at this stage can include:
Trouble coming up with the right words and using the wrong ones
A hard time planning or solving problems
Confusion about time or place. He may get lost in places he’s been before. Once he’s there, he may not know how or why he got to that place.
Not dressing for the weather
Getting angry or upset easily, sometimes lashing out at family or caregivers
