Everyone struggles to come up with a name once in a while. But how can you tell if it’s more serious? “One symptom alone does not necessarily indicate that a person has Alzheimer’s or dementia,” says Raj C. Shah, MD, of the Rush Memory Clinic at Rush University Medical Center, in Chicago. Dementia is chronic loss of cognition, usually affecting memory, and Alzheimer’s causes 50 to 80 percent of dementia cases.
There are many other causes of memory loss, including vitamin B12 deficiency, and brain, thyroid, kidney, or liver disorders. However, having several other symptoms could be a sign of Alzheimer’s disease (AD). Recognizing the signs of dementia can help lead to a quicker diagnosis.
I have come up with the list of symptoms never to ignore, says science.
1. Memory Loss
Serious memory loss and confusion are not a normal part of aging. But forgetfulness caused by stress, anxiety, or depression can be mistaken for dementia, especially in someone who is older.
“We all forget the exact details of a conversation or what someone told us to do, but a person with AD will forget what just happened, what someone just said, or what he or she just said and therefore repeat things over and over again,” says Lisa P. Gwyther, co-author of The Alzheimer’s Action Plan: A Family Guide.
Memory loss isn’t consistent, and people with AD may forget the dog’s name one day and remember it the next. “Nothing is certain or predictable with most dementias except they do progress,” says Gwyther.
2. Agitation and Mood Swings
It’s common for someone suffering from AD to seem anxious or agitated.
They may constantly move around and pace, get upset in certain places, or become fixated on specific details. Agitation usually results from fear, confusion, fatigue, and feeling overwhelmed from trying to make sense of a world that no longer makes sense, explains Gwyther.
Certain circumstances can also make the individual more anxious, such as relocating to a nursing home. In addition to agitation, rapid and seemingly unprovoked mood swings are another sign of dementia–going from calm to tearful to angry for no apparent reason.
