What to notice in the house
Open the fridge. Out-of-date food, very little food, or a lot of food bought repeatedly are all worth noting. Look at whether meals are being cooked or whether everything is cold and quick. Look at the laundry, the bins, and whether the kitchen shows signs of actual cooking.
Look for unopened post, especially anything that looks official, and for medication: full boxes near the end of a month, or several months of the same prescription accumulating, both suggest doses are being missed.
Check the bathroom for signs that washing has become difficult — a bath being avoided in favour of a flannel, for instance — and look for scorch marks, burns on pans, or a smoke alarm that has been disabled because it kept going off.
What to notice in the person
Weight loss is the single most important physical sign, and clothes fitting differently is often the first clue. Unexplained bruising, particularly on the arms or hips, can indicate falls that have not been mentioned — people frequently conceal falls precisely because they fear the conversation that follows.
Watch for a shrinking world: activities dropped, friends not seen, church or the club stopped, the car used less or not at all. Withdrawal is often practical rather than emotional — someone stops going out because getting ready has become exhausting.
Repetition in conversation, difficulty with familiar tasks, or confusion about time and place deserve a GP appointment rather than a wait-and-see.
Ordinary ageing, or something more
Being slower, needing more rest, occasionally losing a word or a name — these are ordinary and by themselves signify little. What matters is change over months, and pattern across several areas at once.
The clearest test is usually function rather than memory: not whether someone forgot a name, but whether they are still managing the things they always managed. Someone who has always been house-proud living in a suddenly untidy home is telling you something.
What to do next
Start with the GP. A review can pick up treatable causes that look like decline — a urinary infection, an underactive thyroid, depression, or simply the side effects of a medication combination that has quietly accumulated over years.
Then ask the council for a care needs assessment. It is free, it is available to anyone regardless of finances, and it produces a written picture of what would help. Even if you arrange and pay for everything privately afterwards, having that assessment is useful.
And begin the conversation early, while it is still hypothetical. It is far easier to discuss what someone would want before the decision is urgent.
