It can creep up quietly. A friend who used to ring every week now waits for you to call. A parent who loved the Saturday market says they can’t be bothered any more. A brother-in-law who was always the life of the party stays home from the family barbecue, then the next one, then the one after that.
When someone we care about starts pulling away in later life, it’s natural to wonder whether something is wrong. Sometimes it is. Often it isn’t. Research on how social lives change with age gives a useful way to tell the difference, and some reassuring evidence about what a little effort from the people around them can do.
Some narrowing is normal, and can even be healthy
Most people’s social circles shrink as they get older, and that isn’t necessarily a problem. In a study that followed people aged 18 to 94 for ten years, psychologists Laura Carstensen of Stanford University and Tammy English found that social networks started to get smaller from midlife onwards. But the loss was mainly among peripheral contacts, such as acquaintances and colleagues, not close friends and family. Older participants also reported that the people in their lives brought them more positive feelings and fewer negative ones than younger participants did.
This fits Carstensen’s long-running theory of socioemotional selectivity. As her Stanford lab puts it, when people see their time as more limited, goals related to “emotional satisfaction and meaning are prioritized”. In everyday terms, that often looks like fewer catch-ups with people they barely know and more time with the ones they love.
So a parent who has stopped going to the work reunion, or who says no to a large party but still loves Sunday lunch with the family, may simply be choosing. That is very different from someone who is losing touch with the people closest to them.
Changes that are worth noticing
None of the signs below proves anything on its own, and none of them is a diagnosis. But when several turn up together, or when they represent a real change from how someone used to be, they are worth paying attention to.
Pulling back from close people, not just distant ones. The research on healthy narrowing describes peripheral contacts falling away while close relationships hold steady. When it’s the closest relationships that start to fade, such as a best friend, a sibling or the grandchildren, that pattern is different.
Losing interest in things they used to love. The garden goes untended, the choir is dropped, the golf clubs stay in the shed. A fact sheet based on a presentation by Beyond Blue’s older adults project manager lists “withdrawing and not socialising” among the behavioural signs of depression in older people, alongside feeling tired all the time, waking early, changes in appetite, irritability and poor concentration.
Avoiding conversation, especially in groups or noisy places. Sometimes withdrawal has a very practical cause. Someone who is struggling to hear may start avoiding restaurants, family gatherings and phone calls simply because keeping up is exhausting or embarrassing. A 2020 systematic review of 14 studies, led by Aishwarya Shukla, found that hearing loss was associated with a higher risk of loneliness and social isolation in most of the studies that adjusted for other factors. Most of those studies were snapshots in time, so they can’t show which came first, but the link is consistent.
Changes in personality or confusion alongside the withdrawal. The Australian Psychological Society lists “loss of interest in people and events” and withdrawal among the possible signs of dementia, along with changes in mood. Withdrawal alone is far more likely to have another explanation, but if it comes with memory problems or uncharacteristic behaviour, it is worth raising with a doctor.
A recent loss. The death of a partner or close friend, a move away from a familiar neighbourhood, giving up the car or a health scare can all shrink a person’s world quickly. Pulling back for a while after a loss is a normal part of grief. It’s when the world stays small, month after month, that it may need a gentle nudge.
Why it matters
Isolation in later life is more common than many people realise, and it has real consequences. In June 2025 the World Health Organization’s Commission on Social Connection estimated that social isolation affects up to one in three older adults, and that loneliness, which affects about one in six people worldwide, is linked to more than 871,000 deaths a year. The WHO linked loneliness and isolation to higher risks of stroke, heart disease, diabetes, cognitive decline and early death, and said lonely people are twice as likely to become depressed.
Those are population figures, and most of the research behind them shows associations rather than direct causes. But they are a reminder that a shrinking world is not always a harmless one.
Reaching out may mean more than you think
One of the things that stops people making contact is the worry that it will be awkward or unwelcome. The evidence suggests that worry is usually misplaced.
In a series of experiments with more than 5,900 participants, published in the Journal of Personality and Social Psychology in 2022, Peggy Liu of the University of Pittsburgh and colleagues asked people to get in touch with someone they hadn’t spoken to in a while, with a short message, a note or a small gift. Every time, the people reaching out underestimated how much it would be appreciated. The gap was largest when the contact came as a surprise.
A few approaches tend to work better than a general “Let me know if you need anything”:
- Make a specific invitation. “Can I pick you up for a coffee on Thursday morning?” is easier to say yes to than an open offer.
- Choose an easy setting. If hearing might be part of the problem, a quiet café or a walk side by side is kinder than a busy restaurant.
- Keep it low pressure. A regular phone call at the same time each week, or a standing invitation to Sunday lunch, can be easier to accept than a big outing.
- Listen more than you advise. Asking how they are, and really waiting for the answer, often does more than suggesting solutions.
- Raise health gently. If you suspect hearing loss, low mood or memory problems, encourage a visit to the GP as an ordinary check-up rather than a crisis.
When to get more help
This is general information, not medical advice. If someone you care about seems persistently low, has lost interest in most things, or you are worried about their memory, their GP is a good first step. Beyond Blue offers support on 1300 22 46 36. If you are ever concerned that someone may be thinking about suicide, or is in immediate danger, call Lifeline on 13 11 14 or 000 in an emergency.
Small, steady contact
Not every quiet retreat needs fixing. Some people are happiest with a small circle and plenty of time to themselves, and the research suggests that is often a sign of good judgement rather than trouble. The difference lies in whether the people who matter most are still close.
When they seem to be slipping away, the most useful response is often the simplest one: a call, a visit, an invitation, made a little more often than feels necessary. On the evidence, it is likely to be more welcome than you expect.
