Normal Forgetfulness or Dementia? Check 7 Warning Signs and How to Self-Assess Before Seeing a Doctor

A collection of methods to observe the differences between normal forgetfulness and dementia warning signs. Learn how to distinguish them, with a basic self-assessment and advice on keeping your brain healthy before visiting a doctor.

Learn to differentiate between “age-related forgetfulness” and “dementia warning signs.” Check for abnormal symptoms that affect daily life and use a basic medical self-assessment method for timely treatment.

Clear distinction! What types of forgetfulness are normal, and which indicate “dementia”?

Forgetfulness can affect people of all ages, especially under stress or lack of rest. However, for elderly people or those aging, the recurring question is: “Is this forgetfulness just normal aging or an early sign of dementia?” Understanding the difference helps us monitor symptoms and get diagnosed sooner.

Differences Between Age-Related Forgetfulness and Dementia Warning Signs

According to information from the Institute of Neurology, Department of Medical Services, the following key differences are noted:

• Normal forgetfulness: Usually temporary memory lapses such as forgetting car keys or occasional appointments, but the person can recall them later and still perform complex daily activities independently.
• Dementia symptoms: Forgetting recent events, repeatedly asking the same questions within a short time, difficulty performing familiar tasks (e.g., forgetting how to use a TV remote), and importantly, these symptoms interfere with daily life.

7 Warning Signs to Watch For (Red Flags)

If you or someone close to you exhibits more than 2-3 of the following symptoms, consider consulting a doctor.

1. Short-term memory loss: Frequently forgetting newly learned information or important dates to the extent of needing constant memory aids.
2. Confusion about time and place: Getting lost in familiar areas or not knowing the current day or season.
3. Unusual misplacement of items: For example, putting a phone in the refrigerator and being unable to retrace steps to find it.
4. Language and communication difficulties: Trouble finding words or clearly misnaming objects.
5. Poorer judgment: Making mistakes in managing money or no longer able to maintain personal hygiene as before.
6. Changes in mood and personality: Becoming easily irritated, suspicious, or socially withdrawn.
7. Difficulty with daily tasks: Forgetting steps in cooking or other activities that have been routine for a lifetime.

Basic Self-Assessment Methods

Besides observing behavior, doctors often recommend basic cognitive tests such as:

• Clock Drawing Test: Draw a circle, place numbers 1-12 correctly, and draw clock hands to show a specified time (e.g., 10:10). People with brain abnormalities often misplace numbers or clock hands.
• Short-term memory test: Have a close person name three objects (e.g., car, flower, table), then after 5-10 minutes, try to recall all the objects to see if memory is intact.
• Caution: This preliminary assessment is not a diagnosis but a screening tool to decide whether to visit a neurologist or a specialized psychiatrist.

Basic Brain Protection and Care

While some types of dementia such as Alzheimer’s cannot be cured, lifestyle changes can slow brain decline.

• Exercise your brain: Read books, play brain games, or learn new skills.
• Manage risk factors: Monitor and keep blood pressure, cholesterol, and blood sugar within normal ranges.
• Regular physical exercise: Improves blood flow to the brain.
• Sleep well: Get enough rest to allow the brain to clear waste (Amyloid Beta) during the night.
