Normal forgetfulness can happen
Occasionally forgetting a name, misplacing an item or needing more time to recall information can occur with age and does not by itself mean dementia.
Memory concerns
Memory problems, normal aging and when to seek an evaluation
Occasional forgetfulness can happen with normal aging, stress, poor sleep or distraction. Changes that are persistent, worsening or interfering with everyday tasks deserve medical attention because memory problems can have many causes.

Important use limits
This hub provides education and care navigation, not a diagnosis or dementia test. New, worsening or safety-related cognitive changes should be discussed with a qualified health professional.
Overview
Memory change is a symptom, not a diagnosis
People can notice changes in memory, attention, word finding, planning or other thinking skills for many reasons. The important questions are whether the change is new, how it compares with the person’s usual functioning, whether it is getting worse and whether it is affecting everyday independence.
Function matters
Repeated difficulty managing bills, appointments, conversations, navigation, medications or familiar tasks deserves closer attention.
Many causes are possible
Sleep problems, depression, anxiety, medications, medical conditions, substance use and neurological disorders can all affect memory or thinking.
Normal aging vs a concerning change
Look at frequency, progression and everyday impact
The National Institute on Aging distinguishes occasional age-related forgetfulness from more persistent changes that interfere with daily tasks or judgment.
More consistent with ordinary forgetfulness
Forgetting the day and remembering later, occasionally missing a payment or sometimes losing an item can happen without a neurocognitive disorder.
More concerning
Repeated trouble managing bills, losing track of time, frequent poor judgment, difficulty carrying on a conversation or often misplacing things without being able to retrace steps warrants evaluation.
Talk with a clinician when concerned
NIA advises discussing memory or thinking changes that concern you with a health professional rather than relying on self-diagnosis.
Possible causes
Memory problems can have reversible, treatable or progressive causes
A clinician may consider sleep, mood, medications, substance use, hearing or vision, metabolic or neurological conditions and other contributors based on the person’s history and symptoms.
Sleep and mental health
Poor sleep, depression, anxiety and high stress can reduce attention and make information harder to encode or retrieve.
Medication and medical factors
Some medicines and health conditions can affect cognition. A medication review and medical evaluation can be an important part of the work-up.
Neurological causes
Mild cognitive impairment, dementia and other neurological conditions are among the possible causes, but an online task cannot determine which explanation applies.
Evaluation
A useful assessment starts with history and everyday functioning
Depending on the concern, evaluation may include a medical history, medication review, neurological or physical examination, cognitive screening, laboratory testing and, when useful, more detailed neuropsychological assessment.
- Describe when the change started and whether it is progressing.
- Bring examples of tasks that have become harder.
- List medications, supplements, sleep problems and relevant health changes.
- When appropriate, input from someone who knows the person well can help describe changes over time.
Online cognitive tasks
Working-memory performance is not a dementia screen
The DesperateMinds Working Memory Test measures performance on a short browser task. Scores can be affected by attention, device, fatigue, distraction, strategy and familiarity. The task is not normed or validated to diagnose dementia, mild cognitive impairment or neurological disease.

Sudden confusion or abrupt cognitive change can be urgent
Sudden confusion, inability to stay awake, new weakness, trouble speaking, severe headache, a recent head injury or other abrupt neurological change can require emergency medical evaluation. Do not wait for an online test when symptoms begin suddenly or safety is uncertain.
Memory change
Look for progression and loss of everyday function, not isolated lapses
Everyone forgets names, misplaces objects or loses a train of thought sometimes. Memory concerns become more important when there is a clear change from previous ability, the problem is getting worse, or it begins to interfere with tasks that were previously manageable.
| More consistent with ordinary lapses | More concerning change |
|---|---|
| Occasionally forgetting an appointment but remembering later or using reminders successfully. | Repeatedly missing important events or being unable to manage previously familiar routines. |
| Taking longer to recall a name or word. | Increasing difficulty following conversations, finding common words or understanding familiar information. |
| Misplacing an item and retracing steps. | Frequently placing items in unusual locations and being unable to work out what happened. |
| Needing more time for a complex task. | New difficulty managing finances, medications, navigation or other everyday responsibilities. |
Memory symptoms can have many causes
Sleep problems, depression, anxiety, medication effects, substance use, hearing or vision problems, thyroid or nutritional issues and other medical conditions can affect memory and concentration. A clinician can review onset, progression, medications, health history and daily functioning before deciding whether formal cognitive testing or specialist evaluation is appropriate.
A browser working-memory task measures a narrow performance skill and is not a dementia screen. Sudden confusion, abrupt cognitive change or new neurological symptoms should be treated as urgent medical concerns.
Preparing for evaluation
A concrete history helps distinguish memory problems from attention or retrieval problems
Bring examples of what is going wrong: forgetting recent conversations, missing appointments, repeating questions, losing track of familiar tasks, getting lost, or struggling with finances and medications. Note whether the problem is stable, fluctuating or progressively worsening.
A medication list, sleep history, alcohol or substance use, hearing and vision problems, mood symptoms and major medical conditions are relevant because each can affect cognitive performance. If a trusted person has noticed changes, their observations can add useful information about everyday functioning.
Formal neuropsychological testing is not automatically required for every memory complaint. A clinician may begin with medical history, brief cognitive screening and examination, then decide whether laboratory testing, imaging, specialist referral or more detailed cognitive assessment is appropriate.
