Summary: When to Worry and When Not To

Beverly Okafor and Janet Reiss have been meeting for Tuesday lunch for nine years. They are 71 and 70, both retired, and today at the Italian place on Grant Street they are comparing memory stories the way they always do. Beverly forgot where she parked. Janet forgot her dentist appointment. They laugh about it. They have been laughing about it for two years.

Beverly notices something she cannot name. Janet’s laugh arrives a fraction of a second later than it used to. She does not know whether it means something or whether she is manufacturing fear out of friendship and too many articles about Alzheimer’s.

The brain at 70 is not the brain at 30, and the differences are normal, documented, and do not indicate dementia. Processing speed declines. Words take longer to arrive. You forget why you walked into the kitchen and remember when you return. The neurons are intact. The networks are intact. The highway is the same highway with a lower speed limit. That is age-related cognitive change.

The other side of the line is specific. The Alzheimer’s Association’s ten warning signs distinguish normal from concerning: forgetting where you put your keys is normal, forgetting what keys are for is a warning sign. Getting lost on a new road is normal, getting lost on the route you have driven for thirty years is not. No single incident constitutes a diagnosis. The distinction that matters is between a moment and a pattern, and the pattern unfolds over months.

The mechanism beneath the difference is what makes the distinction clinically real. Age-related changes are slowdowns in healthy tissue. Early dementia involves the death of neurons and the disruption of neural networks. You cannot tell from the outside which is which. Only a physician can.

The right first call is your primary care physician. A cognitive assessment visit involves a conversation about what you have noticed, a screening test that takes about ten minutes, and a physical exam looking for completely reversible causes of cognitive complaints: thyroid dysfunction, vitamin B12 deficiency, medication side effects, depression. These treatable causes produce symptoms that look like early dementia and are not.

The hardest part is making the appointment. The fear that asking the question confirms the answer. But asking does not change the answer. If the answer is normal aging, the appointment produces relief and a baseline. If the answer is something else, the appointment produces information at the moment when that information has its maximum value. Early-stage cognitive impairment is the period of greatest agency: plans can be made, preferences stated, documents prepared, clinical trials considered. The window of action is widest at the beginning.

Beverly should not diagnose her friend. A fraction of a second’s delay in a laugh is not a clinical sign. What she can do is pay attention without catastrophizing, notice whether the pattern repeats over months, and know the difference between a concern worth raising now and one worth watching. Today is a watching day. It may stay a watching day. That would be a good outcome.

They finish lunch. Janet picks up the check and calculates the tip correctly. The math is fine. The laugh is still a fraction of a second late. Beverly does not know what either of those things means. She knows where to find out.
