Information about Normal "Senior Moments" & Serious Memory Loss

Occasional memory lapses, such as forgetting why you walked into a room or having difficulty recalling a person's name, become more common as we approach our 50s and 60s. It's comforting to know that this minor forgetfulness is a normal sign of aging, not a sign of dementia.

But other types of memory loss, such as forgetting appointments or becoming momentarily disoriented in a familiar place, may indicate mild cognitive impairment. In dementia—the most serious form of memory impairment—people often find themselves disoriented in time and place and unable to name common objects or recognize once-familiar people.

Here are some examples of the types of memory problems common in normal age-related forgetfulness, mild cognitive impairment, and dementia.
