“My memory is not what it used to be.” It is one of the most common ways people describe a growing concern. The statement may be accurate. It may also be influenced by stress, poor sleep, a recent mistake, or the fact...

You may know that memory changes with age. That knowledge does not always make everyday lapses easier to interpret. When a word disappears or you forget part of a conversation, you may wonder:

Forgetting a name or losing your train of thought in midlife is often harmless. Learn which patterns are usually normal, which warning signs deserve attention, and what to do next.
