Normal Forgetfulness or Dementia? Signs Families Should Not Miss
Forgetting where the spectacles went is normal ageing; forgetting what spectacles are for, getting lost on a familiar road, or paying the milkman three times in a week is not. This guide helps families tell normal forgetfulness from dementia (bhoolne ki bimari), note what they see, and get the right checks, including the treatable causes that doctors look for first.
The short version
- Normal: slow to recall a name, then it comes back later.
- Worth a check: repeating the same question within minutes, getting lost, money mistakes, a changed personality.
- Treatable look-alikes: low B12, thyroid problems, depression, poor hearing, and medicine side effects.
- Emergency, not dementia: confusion that starts over hours or a day or two.
- Who to see: the family doctor first, who may refer to a neurologist, psychiatrist or geriatrician.

Normal forgetfulness vs dementia: where is the line?
Everyone’s memory gets slower with age. That’s it. Slower, not broken.
A healthy 70-year-old may walk into the kitchen and forget why, lose the name of a cousin’s son at a wedding, or need a list for the bazaar, and none of that is a disease, because the information is still stored and usually surfaces an hour later, often while doing something else entirely. Dementia is different. The memory isn’t just slow to arrive; it was never laid down, or it’s gone. And it isn’t only memory. Dementia is a group of brain conditions (Alzheimer’s is the most common kind) where thinking, judgement, language and daily skills slowly decline until they get in the way of ordinary life.
That last part is the real test. Doctors ask: is this change stopping a person from doing things they managed well a year or two ago?
| Usually normal ageing | Worth a doctor’s check |
|---|---|
| Forgets a name, remembers it later | Forgets close relatives’ names or who they are |
| Misplaces keys, retraces steps to find them | Puts keys in the fridge, accuses others of stealing |
| Makes an odd slip with the gas bill | Can’t manage money they always handled |
| Needs a moment for a word | Stops mid-sentence often, calls a watch “the hand clock” |
| Gets tired of big gatherings | Withdraws, becomes suspicious, irritable or flat |
Early dementia signs families should not miss
These are the changes relatives in joint families notice first, often before the person does.
Repeating and asking again
The same story told twice in one visit, or “Has Asif come home?” asked four times in half an hour. Once is nothing. A pattern over weeks matters.
Getting lost in known places
Coming back late from the mosque or mandir they’ve walked to for 30 years, or not recognising their own lane. This one is a safety sign as well as a memory sign.
Money and paperwork mistakes
Unpaid bills that were always paid on time, cash handed over twice, a sudden interest in “prize” phone calls. Scammers target exactly this change, so it’s worth protecting bank cards and PINs early, gently.
Personality and mood change
A calm person who becomes suspicious or snappy, a sociable one who stops visiting, or someone who suddenly makes odd remarks at the dinner table. Families often blame “old age temper”. Sometimes it’s the first sign.
Trouble with familiar tasks
Burning the daal they’ve cooked all their life, forgetting steps of wudu or a puja they know by heart, struggling with the TV remote they used easily last year.
The question isn’t “does Ammi forget things?” but “can she still do what she could do last year?”
Treatable causes doctors check first
Here’s the hopeful part. Some memory trouble has a cause that can be found and managed, and a good doctor rules these out before using the word dementia.
- Low vitamin B12: common in older people, in vegetarians, and in people on long-term acidity or diabetes medicines. It can also cause tingling or burning feet (see burning feet and B12). A blood test answers it.
- Thyroid problems: an underactive thyroid can make someone slow, tired and foggy.
- Depression: in older people it often looks like poor memory and poor concentration rather than sadness. It’s sometimes called “pseudo-dementia”.
- Poor hearing and eyesight: a parent who can’t hear the question can’t answer it, and looks confused. Hearing loss in older relatives is easy to miss and worth checking alongside memory.
- Medicines: sleeping pills, some allergy and bladder medicines, strong painkillers and several others can cloud thinking. Take every strip and bottle to the appointment. Never stop one on your own.
- Poor sleep, low salt (sodium), infections, heavy drinking, and rarely a slow bleed or fluid build-up in the brain after a fall.
So “it’s just age” isn’t an answer. It’s a guess.
What to note before the doctor visit
Doctors get 10 or 15 minutes, and a parent may perform beautifully in the clinic (many people do). A short diary from the family is worth more than a long worried speech.
- Keep a notebook for 2 to 4 weeks. Write the date and one line for each incident: what happened, not your opinion of it.
- Note three things for each: memory (what was forgotten), task (what couldn’t be done), and mood or behaviour.
- Write when it started and whether it came on slowly over months or suddenly over days. Sudden change is urgent (see below).
- Collect every medicine, including herbal, Unani and Ayurvedic ones, eye drops and anything bought from the chemist without a prescription, in one bag.
- List past illnesses: diabetes, BP, stroke, head injury, thyroid, heart problems.
- Agree beforehand who goes. One calm relative who sees the parent daily is better than four who don’t.
- Ask the doctor directly: “Could this be B12, thyroid, depression, hearing or a medicine?”
The doctor may do a short memory test in the room, blood tests, and sometimes a brain scan. Many cities in Pakistan and India have memory clinics in teaching hospitals; your family doctor can refer.
Confusion starts suddenly over hours or a day or two; that is usually delirium from an infection, dehydration, low sugar or a new medicine, not dementia. Also go at once for a fall with hip pain or any head injury, not eating or drinking for a day, chest pain, new wetting with fever, or stroke signs (face drooping, arm weakness, slurred speech: call emergency). Don’t start, stop or change any medicine on your own; ask for a medicine review instead.
How to talk about it kindly
This part hurts. Nobody wants to be told they’re losing their mind, and many elders fear being called “pagal” or losing their place in the house.
- Say “Let’s get your B12 and thyroid checked, and your hearing” rather than “We think you have dementia”.
- Don’t quiz them at the dinner table (“What did you eat today? Who’s this?”). It shames and proves nothing.
- Don’t argue with a wrong memory. Correct gently if it matters, and let it go if it doesn’t.
- Keep them in family decisions for as long as possible. Being useful protects dignity.
Words matter in the extended family too, where an uncle may say “sathiya gaye hain” (gone senile). A calm, medical framing helps everyone.
In many homes, badam at breakfast, a spoon of khamira or brahmi were given “for the memory”. They’re part of food culture and tradition, and nothing in them reverses dementia. Don’t let a jar in the cupboard delay a proper check. Herbal products can also clash with prescribed medicines, so mention them to the doctor.
Myth: forgetfulness in old age is always dementia
Most older people never develop dementia. Slower recall is normal. The myth does harm in both directions: families panic over normal slips, or they shrug at real warning signs because “everyone’s grandmother forgets things”. Watch for change in what a person can do, not just what they remember.
Did you know? Poor hearing is one of the changeable things linked with memory decline in later life, which is one reason hearing checks sit in a memory assessment. Loneliness matters too; loneliness in old age is worth a look if a parent spends most days alone. More guides for families sit under Desi Remedies.
Dementia and memory loss: questions families ask
How do I know if it’s normal forgetfulness or dementia?
Ask whether the forgetting stops them doing things they managed a year or two ago. Forgetting a name and remembering later is normal. Getting lost, repeating questions within minutes, or failing at money and cooking they always handled needs a doctor’s check.
What are the first signs of dementia in elderly parents?
Repeating the same question or story, getting lost in known places, money mistakes, trouble with familiar tasks, and personality change such as suspicion or withdrawal. Families usually see a pattern over weeks rather than one event.
Can vitamin B12 deficiency cause memory loss?
Yes, low B12 can cause memory trouble, confusion, tiredness and tingling feet. It’s common in older people and those on long-term acidity or diabetes medicines. A simple blood test checks it, and the doctor decides on any treatment.
Is sudden confusion a sign of dementia?
No. Confusion that appears over hours or a day or two is usually delirium, caused by infection, dehydration, low sugar or a medicine. It’s an emergency and needs a doctor the same day.
Which doctor should we see for memory problems?
Start with the family doctor or physician. They check blood tests, hearing and medicines, then refer to a neurologist, psychiatrist or geriatrician, or a hospital memory clinic, if needed.
Can depression look like dementia in old age?
It can. Depression in older people often shows as poor concentration, slowness and forgetfulness rather than tears. It’s treatable, so it’s one of the first things a doctor considers.
Can medicines cause memory loss in the elderly?
Some can, including certain sleeping pills, allergy medicines, bladder medicines and strong painkillers. Bring every medicine to a review. Never stop one without the doctor, because stopping suddenly can be harmful too.
Do memory tests at home tell you if someone has dementia?
No. Online quizzes and home tests can’t diagnose it, and a bad day can look worse than reality. A written diary of real incidents is far more useful to the doctor.
Do almonds or brahmi prevent dementia?
There’s no good evidence they prevent or reverse it. Almonds are a fine food. Herbal products can interact with medicines, so tell the doctor about them, and don’t use them to put off a check.
Is dementia hereditary?
Having a parent with dementia raises the risk a little, but most cases aren’t passed down in a simple way. Controlling BP, diabetes, hearing loss and staying active and social all matter more for most families.
How do you tell a parent they need a memory check?
Frame it as a general health check: B12, thyroid, hearing and eyes. Avoid the word dementia at first, choose a calm moment, and let the person they trust most bring it up.
