Yes. Repeated questions can have treatable causes besides dementia, including medication effects, depression, sleep problems, vitamin B12 deficiency, thyroid disease, and acute illness. However, frequent repetition is a meaningful memory change, not a diagnosis. The National Institute on Aging says clinicians should assess the cause rather than assume it is dementia based on this memory-loss guidance.

Which treatable problems can affect memory?
Several health problems can make it difficult to retain an answer or follow a conversation. These include medication side effects, metabolic or endocrine problems, and delirium caused by illness. Depression, anxiety, poor sleep, stressful events, and alcohol or drug misuse can also disrupt memory.
Symptoms connected to stress or negative emotions are often temporary as those pressures ease. Low vitamin B12 and thyroid disease are other possible contributors. Some causes may improve with treatment, especially medication effects and untreated depression, although improvement depends on the underlying problem.
Did the repetition begin suddenly?
Timing matters. dementia usually is not the only concern when confusion or difficulty following a conversation appears suddenly. The NHS lists infection, stroke or transient ischemic attack, low blood sugar, head injury, medicines, alcohol, and seizures among possible causes of sudden confusion requiring immediate medical assessment.
Do not wait for a routine memory appointment if the person abruptly becomes confused or cannot remember what was just said. Other concerning causes of new memory loss include concussion, brain infection, tumor, hydrocephalus, severe illness, and low oxygen. An abrupt change needs medical evaluation, not an assumption that aging or dementia explains it.
Could it be normal aging or mild cognitive impairment?
Normal aging can make learning and recall slower. It does not cause dramatic memory loss. Occasionally forgetting an answer and recalling it later differs from repeatedly asking because the answer does not remain in memory.
Mild cognitive impairment, or MCI, causes greater memory difficulty than expected among similar-age peers while leaving daily independence intact. Not everyone with MCI develops Alzheimer's disease. The practical dividing line is not repetition alone. Frequency, progression, and effects on medication use, appointments, finances, conversations, or other daily activities help show how significant the change may be.
What will a clinician investigate?
A clinician will usually ask when the repetition began, whether it is worsening, and what seems to trigger it. MedlinePlus notes that an evaluation may include tests for vitamin B12 deficiency or thyroid disease when indicated.
Before the appointment, record concrete examples: A family member or caregiver may notice patterns the person does not remember. Specific observations are more useful than saying only that the person seems forgetful.

What should you do now?
Arrange a professional assessment when repeated questioning persists, worsens, worries the person or family, or interferes with daily life. The symptom can occur with dementia and with treatable conditions, so repetition alone cannot distinguish between them.
Do not start an unproven "memory" pill or supplement while waiting. The National Institute on Aging warns that such products may be unsafe or interfere with other treatments. Seek immediate medical help instead if the change is sudden or includes new confusion or an inability to follow conversation.
