Is my parent getting forgetful, or is it something more?

You've been noticing things. Mom calls twice in an hour and doesn't remember she called. Dad asks how you got there, then asks again 20 minutes later. A grandchild's name slips and doesn't come back. You're probably not imagining it. And you don't need a diagnosis to act: roughly 75% of dementia worldwide goes undiagnosed, and the worry you're carrying is the most common first signal.

• Occasionally forgetting a name and remembering it later.
• Briefly losing your train of thought mid-sentence.
• Walking into a room and not remembering why for a second.
• Needing more time to learn new technology.
• Recalling old memories sharply while sometimes fumbling recent ones.

• Repeating the same question or story within minutes.
• Getting lost in places they should know.
• Trouble with familiar tasks: bill paying, a 30-year recipe, dressing in the right order.
• Personality or judgment shifts: paranoia, uncharacteristic spending, impulsive decisions.
• Word-finding difficulty that's gotten noticeably worse.
• Withdrawal from things they loved (church, bridge club, daily walks).
• Losing important things repeatedly (keys in the fridge, mail in the freezer).

Three obstacles 'how to tell' guides rarely acknowledge. Anosognosia, a brain-based loss of self-awareness, affects ~60% of people with MCI and 81% with Alzheimer's (Frontiers in Aging Neuroscience, 2024); they neurologically cannot agree anything is wrong. Even when families arrange evaluation, primary-care diagnostic sensitivity for mild dementia is only 9–41% (Bradford et al., 2009). And Non-Hispanic Black and Hispanic families experience diagnostic delays 11–40% longer (Alzheimer's & Dementia, 2024). Recognition is the start of a process that may take multiple encounters and specialist referral.

• Schedule a doctor visit; frame it as a regular check-up. Ask for a cognitive screening (MoCA or MMSE).
• Ride along if allowed. Adult children often catch things the parent omits.
• Bloodwork to rule out reversible causes: thyroid, B12 deficiency, depression.
• Walk in with data, not impressions. A 12-month chart of repetition, vocabulary, name recall, and time-orientation gets the doctor to act in 30 seconds. Familiar's Daily Calls in Family Voices export exactly that as a clinician-formatted PDF.
• Ask about the pTau217 blood test (Precivity AD2, C2N Diagnostics). Dr. Rudolph Tanzi (Harvard Medical School; Director of MassGeneral's Genetics and Aging Research Unit) describes on the Nothing Left Unsaid podcast, May 2026 how the test can detect Alzheimer's pathology years before symptoms, opening a window for intervention while the brain is still largely intact.
• Refer to a neurologist if the screen suggests concern. Disease-modifying drugs for early Alzheimer's exist now; don't wait for a crisis event.

Most older adults sense something is changing before family says anything; fear is often greater than frustration. Concern *for* them lands better than concern *about* them. 'I want you to feel sharp for the next 20 years and I'd rather check sooner' is a different sentence than 'I think you might have dementia.'

If they refuse, accept once and try again later. Multiple gentle conversations beat one big one. Their primary care doctor can also raise it as routine, which is often easier to accept.
