Is it normal for memory to decline with age, or is it dementia?
My mother is 72 and sometimes forgets names or where she put her keys, but she manages her finances and cooks every day. How do we tell the difference between normal age-related memory changes and early dementia?
✓ Accepted answer
It is completely normal for memory to decline slightly with age, and the specific patterns your mother is describing are typically indicative of healthy cognitive aging rather than dementia.
To distinguish between the two, focus on functionality and severity. Isolated lapses are common. Forgetting a name or the location of keys is a typical age-related change, whereas dementia usually involves difficulty finding words while speaking or losing the thread of conversation entirely. Independence is maintained. Because your mother still manages her finances and cooks, she is demonstrating executive function and complex problem-solving skills that often deteriorate in the early stages of Alzheimer’s. Learn new skills. Normal aging involves occasional difficulty learning new complex tasks, but individuals usually figure out workarounds; dementia patients typically forget how to perform familiar tasks they have done for decades, like paying bills or operating a stove. Context is lost. Older adults may forget they attended a meeting but usually can recall it if prompted; those with dementia often forget the event occurred at all and may ask the same questions repeatedly within minutes. Consult a professional. If you notice personality changes, severe disorientation, or a decline that interferes with daily safety, schedule a baseline cognitive assessment with a primary care provider or a geriatric psychiatrist. The NIH and CDC recommend regular health screenings to monitor cognitive health as part of general wellness.
