Track recent memory loss before a dementia evaluation by keeping a dated log of specific changes, their frequency, possible triggers, and effects on daily life. Add a symptom timeline, a complete medicine list, and relevant health or behavior changes for the appointment. A symptom log is a running record of what happened and when, not an attempt to diagnose the cause. A dementia evaluation uses that history alongside examinations and further testing.

Build a useful symptom log
Record one event at a time while the details are still clear. The Alzheimer's Association guidance on working with the doctor recommends noting each memory, mood, behavior, routine, or eating change, including its timing, frequency, and possible triggers. Use the same fields for every entry: Write "asked about Tuesday's appointment four times that morning," rather than "memory was bad." If the exact date or frequency is unknown, label it as an estimate instead of guessing.
- Date and approximate time
- What happened, using specific details
- How often it has happened
- What occurred immediately beforehand
- Any suspected trigger
Which changes should you record?
Include concrete memory and communication problems. MedlinePlus guidance on cognitive testing identifies examples such as missing appointments, repeatedly losing items, struggling to find words, and losing one's train of thought. Record changes beyond memory, too.
Note new mood or behavior patterns, disrupted routines, eating changes, sleep problems, depression, anxiety, stress, infection symptoms, vascular problems, or a recent fall or head injury. Clinicians may investigate some of these as potentially treatable contributors to thinking problems. Keep observations separate from explanations. Write "slept poorly and forgot the morning appointment," not "poor sleep caused the memory problem." A suspected trigger is useful context, but it is not proof of the cause.
Has everyday independence changed?
For each concern, record whether the person completed the usual activity independently, needed a reminder, required direct help, or could not finish it. Track changes from that person's normal ability rather than judging a single mistake in isolation.
This distinction matters because mild cognitive impairment, or MCI, can involve noticeable memory problems while daily functioning remains intact, according to the MedlinePlus overview of mild cognitive impairment. A missed appointment with no other difficulty therefore provides different information from a growing need for help across usual routines.
Prepare an appointment summary
Create a short timeline showing the approximate onset and progression of symptoms. Include personality or behavior changes and any family history of dementia, as recommended in the National Institute on Aging's dementia diagnosis overview. Bring a complete list of prescription and over-the-counter medicines, their doses, vitamins, and supplements.
The Alzheimer's Association advises including these because medication side effects can contribute to memory or thinking symptoms. Put the earliest noticed change, the most concerning examples, changes in daily independence, and relevant health events on a one-page summary. Bring the full log as supporting detail rather than trying to fit every incident onto that page.
Know the limits and urgent warning signs
A memory diary cannot diagnose dementia, and cognitive screening alone cannot identify dementia or determine its cause. Clinicians interpret the history together with examinations and any further testing they consider necessary. Do not delay medical attention simply to collect more entries if the person develops: The Alzheimer's Association advises prompt medical attention for these changes rather than waiting for a routine dementia evaluation.
- Sudden confusion
- A major, abrupt memory or mood change
- Fainting or falling
- Fever
- New incontinence
