Amma forgot where she kept her spectacles. Again. Papa called your son by your brother’s name at dinner. Is this just age catching up, or the first sign of something bigger?
Most families ask this question quietly, and many wait too long to ask it out loud. This guide gives you a simple way to tell everyday forgetfulness apart from changes that deserve a doctor’s opinion.
The short answerNormal ageing means occasional lapses that a person usually recovers from, such as forgetting a name and remembering it later. Dementia means an ongoing decline in memory, thinking or other brain functions that gets worse over time and starts to disrupt everyday life. If forgetfulness is increasing or interfering with daily tasks, it is time to see a doctor. (Alzheimer’s Association, NHS, CDC)
Side-by-side check
Normal forgetfulness vs possible dementia
Think of the brain like a well-used home library. With age, finding a book can take a little longer. That is different from books going missing from the shelves altogether. The Alzheimer’s Association pairs each early warning sign with what a typical age-related change looks like. (Alzheimer’s Association)
| Usually normal with age | Worth discussing with a doctor |
|---|---|
| Sometimes forgetting names or appointments, but remembering them later | Memory loss that disrupts daily life |
| Making occasional errors with bills or household accounts | Challenges in planning or solving problems |
| Occasionally needing help with settings on a gadget | Difficulty completing familiar tasks |
| Getting confused about the day of the week, then figuring it out | Confusion with time or place |
| Vision changes related to cataracts | Trouble understanding visual images and spatial relationships |
| Sometimes having trouble finding the right word | New problems with words in speaking or writing |
| Misplacing things now and then, and retracing steps to find them | Misplacing things and losing the ability to retrace steps |
| Making a poor decision once in a while | Decreased or poor judgement |
| Sometimes feeling uninterested in family or social obligations | Withdrawal from work or social activities |
| Developing fixed ways of doing things and getting irritable when a routine is disrupted | Changes in mood and personality |
The CDC adds a few more telltale signs: getting lost in a familiar neighbourhood, using unusual words for familiar objects, forgetting the name of a close family member or friend, and not being able to complete common tasks on one’s own. (CDC)
Forgetting where you kept the keys is common. Getting lost on the way back from the neighbourhood market is a reason to get checked.
Look for the pattern
Why those two questions matter most
Beyond memory
Dementia is not only about memory
Many families watch only for memory loss and miss the other signs. Early dementia symptoms include difficulty concentrating, struggling to follow a conversation or find the right word, confusion about time and place, and mood changes. (NHS)
Dementia can also affect thinking speed, understanding, judgement and even movement. (NHS) Some unusual forms of Alzheimer’s disease “can start with problems with vision or with language” rather than memory. (NHS)
The grey zone
The middle ground: mild cognitive impairment
Between “perfectly fine” and “dementia” there is a grey zone. When early symptoms are present but “not severe enough to be diagnosed as dementia,” doctors may call this mild cognitive impairment (MCI). (NHS)
MCI “can be caused by an underlying illness, such as depression, anxiety or thyroid problems.” If that illness is treated, “symptoms of MCI often disappear and cause no further problems.” (NHS)
Worth ruling out
Forgetfulness that may have a fixable cause
“Some memory problems may be caused by treatable conditions” and these “can be reversed when the underlying condition is treated.” (CDC)
- Medicine side effects (CDC)
- Vitamin deficiency (CDC)
- Thyroid hormone imbalance (CDC)
- Increased pressure in the brain (CDC)
- Stress and anxiety (NHS)
- Depression (NHS)
- Sleeping problems (insomnia) (NHS)
This is why “it’s just old age” is a risky assumption. Only a doctor can sort a fixable cause from a progressive one: “Do not try to self-diagnose the cause of your memory loss.” (NHS)

Questions
What families ask us
At what age does dementia usually start?
Dementia is more common after age 65, but it is not an inevitable part of ageing. (WHO) In India, the LASI-DAD study found prevalence rises with age among adults over 60. (Lee et al., 2023)
Can forgetfulness in older adults be reversed?
Sometimes, yes. Memory problems caused by treatable conditions, such as medication side effects, vitamin deficiency or thyroid imbalance, can be reversed when the condition is treated. (CDC)
Is forgetting words a sign of dementia?
Occasionally struggling to find the right word is typical with age. New and persistent problems with words in speaking or writing are a warning sign worth discussing with a doctor. (Alzheimer’s Association)
Your next step
Noticed a pattern? Start with a conversation.
If the changes you are seeing are growing, or getting in the way of daily life, book a visit with your family doctor. That single step can rule out fixable causes or open the door to early support.
If a diagnosis has already been made, Manastik offers dementia rehabilitation at home or by video, coordinated by a Care Navigator who works alongside the treating doctor and supports the family too.
