When Forgetfulness Means More Than Aging: Signs to Watch This World Alzheimer’s Month

Sandra Darling, DO, a preventive medicine physician at Cleveland Clinic, lists concrete warning signs to watch for: frequently missing appointments, forgetting names of familiar people, getting lost in familiar places, or repeating yourself often. She says these patterns should prompt concern and evaluation.

Alzheimer's disease is the most common cause of dementia and typically appears after age 65, but it is not the only explanation for memory problems. Dr. Darling notes other potentially treatable causes such as depression, thyroid disorders, vitamin deficiencies, and poor sleep. Because several conditions can cause similar symptoms, a medical evaluation is the practical next step.

What to expect when you see a doctor

Primary care evaluation typically aims to identify reversible causes and to assess whether cognitive decline points toward dementia. The visit often includes:

• A medical history that asks when problems started, how they have changed, and whether they affect daily tasks like managing money or medicines.

Dr. Darling's recommendation is direct: "You want to see your primary care doctor right away to be evaluated to determine the underlying cause of any memory problems and get treatment." Early treatment can slow or potentially reverse memory problems depending on the underlying cause.

Act promptly if you or a family member notices:

• Missing appointments or important dates repeatedly.
• Frequent repetition in conversation.
• Trouble recognizing familiar people or places.
• New difficulty with routine tasks such as taking medications correctly or handling finances.

If these signs are present, document examples and timelines to bring to the appointment. Details about onset, progression, and everyday impact help clinicians narrow potential causes.

Treatment depends on the cause. For reversible contributors—thyroid problems, vitamin deficiencies, depression, or poor sleep—targeted therapies can improve memory. For degenerative causes such as Alzheimer's, available interventions can sometimes slow decline and help manage symptoms. The article emphasizes that early evaluation improves the chances of finding treatable causes and planning care.

Not every lapse means dementia. Persistent, worsening, or functionally limiting memory problems merit a medical evaluation. Start with your primary care doctor, bring concrete examples, and ask about tests for reversible causes as well as referrals for cognitive assessment if needed. Timely assessment gives the best chance to treat reversible conditions and to plan care if cognitive decline is diagnosed.
