"Normal forgetfulness vs. dementia
For most people, occasional lapses in memory are a normal part of the aging process, not a warning sign of serious mental deterioration or the onset of 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.”
Does your memory loss affect your ability to function?
The primary difference between age-related memory loss and dementia is that the former isn’t disabling. The memory lapses have little impact on your daily performance and ability to do what you want to do. Dementia, on the other hand, is marked by a persistent, disabling decline in two or more intellectual abilities such as memory, language, judgment, and abstract thinking.
When memory loss becomes so pervasive and severe that it disrupts your work, hobbies, social activities, and family relationships, you may be experiencing the warning signs of Alzheimer’s disease, or another disorder that causes dementia, or a condition that mimics dementia
