Normal forgetfulness vs. dementia
For most people, occasional lapses in short-term memory are a normal part of the aging process, not a warning sign of serious mental deterioration or the onset of Alzheimer’s or another dementia.
The following types of memory lapses are normal among older adults and generally are not considered warning signs of dementia:
Occasionally forgetting where you left things you use regularly, such as glasses or keys.
Forgetting names of acquaintances or blocking one memory with a similar one, such as calling a grandson by your son’s name.
Occasionally forgetting an appointment or walking into a room and forgetting why you entered.
Becoming easily distracted or having trouble remembering what you’ve just read, or the details of a conversation.
Not quite being able to retrieve information you have “on the tip of your tongue”
