Dementia Warning Signs: When to See a Geriatrician in Kolkata

When families bring an elderly parent to see me for the first time, they often say the same thing: "We thought it was just old age." Memory slipping. Getting lost in familiar conversations. Forgetting names. These things happen to all of us — and for a long time, families watch and wait, wondering whether what they're seeing is normal ageing or something that needs medical attention.

The question matters more than most families realise. Dementia is not one disease — it is an umbrella term for a group of conditions that affect memory, thinking, behaviour, and the ability to carry out daily activities. Alzheimer's disease is the most common, but there are others: vascular dementia, Lewy body dementia, frontotemporal dementia. Each has a distinct pattern, a different rate of progression, and different management needs.

And while there is no cure for most forms of dementia, early assessment makes an enormous difference — to the person living with it, and to the family caring for them.

What Normal Ageing Actually Looks Like

Before we talk about warning signs, it helps to understand what is genuinely normal.

With age, it is normal to take slightly longer to recall a name or word — but the information comes back later. It is normal to occasionally forget where you put your keys. It is normal to find new technology frustrating, or to take longer to learn a new task.

What is not normal is forgetting what a key is for. What is not normal is becoming lost in the street you have lived on for thirty years. What is not normal is not recognising a family member you have known for decades.

The distinction between normal cognitive ageing and early dementia is not always obvious — but it is one that a geriatrician is specifically trained to assess.

Warning Signs That Warrant a Specialist Assessment

These are the patterns I ask families to watch for:

1. Memory loss that disrupts daily life

Forgetting an appointment and remembering it later — normal. Forgetting an entire event happened at all, and continuing to ask about it in the same conversation — not normal. People in early dementia often repeat the same questions within minutes, with no awareness they have already asked.

2. Difficulty with familiar tasks

An older person who has cooked the same recipes for decades and suddenly cannot follow the steps, or who forgets to turn off the stove, is showing something more than forgetfulness. Difficulty completing familiar sequences — cooking, managing finances, taking medication in the right order — is an early and important sign.

3. Confusion about time and place

Losing track of dates, seasons, or the passage of time is common in early dementia. More concerning is disorientation about place — not knowing where one is, or how one got there — which tends to appear as the condition progresses.

4. Language and communication changes

Struggling to find the right word occasionally is age-related. But when someone stops mid-sentence, cannot find common words, or starts substituting unusual words for familiar ones ("that thing you drink water from" instead of "glass"), this suggests cognitive changes that need evaluation.

5. Withdrawal from social activities

Dementia is exhausting. People in early stages often withdraw from social engagements, hobbies, and activities they previously enjoyed — not because they want to, but because the cognitive effort required has increased beyond what feels manageable. Families often interpret this as depression or "just getting old." It can be both — but it warrants assessment either way.

6. Personality and mood changes

Increased suspicion, anxiety, depression, or irritability — particularly when these are new to the person's character — can be early markers of dementia. Families frequently notice that a previously gentle person has become uncharacteristically harsh, or that a confident person has become fearful.

7. Judgement that seems impaired

Giving large sums of money to unknown callers. Wearing a winter coat in summer. Making decisions that seem disconnected from reality. These changes in judgement are not stubbornness — they reflect a deterioration in the brain's ability to assess and respond to situations appropriately.

What a Geriatric Assessment Involves

When someone comes to me with concerns about memory or cognition, I do not rely on a single test. A Comprehensive Geriatric Assessment (CGA) evaluates multiple domains: memory, executive function (the ability to plan and reason), language, visual-spatial processing, and the capacity to carry out daily activities.

I also look at the whole picture — medications, physical health, depression, sleep, and sensory impairment. Hearing loss, for example, is a significant and underappreciated contributor to cognitive decline and social withdrawal. Thyroid problems, B12 deficiency, and poor sleep are all reversible causes of cognitive symptoms that are frequently missed when a patient only sees a neurologist focused on the brain in isolation.

This whole-person approach is the particular value of geriatric medicine. A geriatrician does not just assess whether dementia is present — we assess whether there are reversible contributing factors, what stage the condition may be at, and what the family needs to know to plan ahead.

The Case for Early Assessment

There is still a widespread belief that there is no point in diagnosing dementia early, because nothing can be done. This is no longer true.

While there is no cure, early diagnosis opens important doors. Medications used in Alzheimer's disease are more effective when started early. Lifestyle modifications — physical activity, cognitive engagement, diet, social connection — have documented evidence for slowing progression. Legal and financial planning is better done early, while the person still has full capacity. And families need time to understand what is ahead and put the right support in place.

I have seen families wait two or three years before bringing a parent in — often because they did not want to upset the person, or because they convinced themselves it was "just age." By the time they came, the window for early intervention had passed.

If you are reading this because something feels off with an elderly parent, that instinct is worth acting on. The earlier the assessment, the more we can do.

When to Come to a Geriatrician Rather Than a General Physician

A GP is an excellent first stop and will often refer onward. But if your parent has multiple health conditions, is on five or more medications, or the cognitive concerns are mixed with physical changes — such as falls, incontinence, or significant weight loss — a geriatrician's multi-domain assessment is more likely to give you the complete picture.

I consult at Manipal Hospital Broadway in Kolkata and offer home visits in the Newtown, Rajarhat, and Salt Lake areas through GeraVita. If you would like to discuss what you are seeing in a parent, please do reach out — a conversation costs nothing and may give you the clarity your family needs.

Frequently Asked Questions

At what age does dementia typically start?

Most dementias occur after age 65, but early-onset dementia can affect people in their 50s. Age is a risk factor, not a guarantee — and many people in their 80s and 90s have no significant cognitive decline.

Is memory loss always dementia?

No. Depression, thyroid dysfunction, vitamin B12 deficiency, medication side effects, and sleep disorders can all cause memory problems that look like dementia but are reversible with treatment. This is precisely why assessment matters.

Can dementia be prevented?

There is no certain prevention, but the evidence for lifestyle factors is strong. Regular physical exercise, intellectual engagement, social connection, good sleep, blood pressure control, and treating hearing loss are all associated with lower risk. These are things a geriatrician can help you act on.

My parent refuses to see a doctor. What should I do?

This is one of the most common situations I encounter. Denial is a normal response to cognitive fear. In this situation, framing the visit as a general health review rather than a memory assessment is often more acceptable. If your parent is open to the idea of a home visit — which is less confrontational than going to a hospital — GeraVita's home-based assessment may be a more comfortable starting point.
