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.
