What are the early signs of dementia?
The short answer
The earliest sign of most dementia types is new short-term memory loss — forgetting recent events, conversations, or where objects were placed, while older memories remain intact. This is the opposite of normal aging, where remote memory tends to be better than recent memory in healthy older adults too — but the gap is qualitatively different in dementia.
