When Someone With Dementia Stops Eating

Unplanned weight loss in dementia predicts decline, infection and falls, so treat it as a medical signal rather than something to be expected.

Before adjusting mealtimes, rule out the causes that have nothing to do with dementia: painful teeth, an ill-fitting denture, a mouth infection, constipation, depression, or medication that has flattened appetite or altered taste. A dental check and a medication review resolve a surprising share of cases.

Someone may not recognise the food as food, or may not see it at all. Pale food on a white plate on a white cloth can effectively disappear when visual processing changes, which is why a single coloured plate so often produces an immediate improvement.

Cutlery may have become a puzzle. The sequence of a meal may have been lost. A busy table with several conversations and a television on can overwhelm attention to the point where eating stops. And swallowing may be genuinely difficult, which is the one that needs professional assessment rather than adaptation.

Use a plain, brightly coloured plate with strong contrast against both the food and the table, and clear the table of everything else. Turn the television off.

Offer one item at a time rather than a full plate, which reduces the decision to something manageable. Finger food often outperforms cutlery by a wide margin: sandwiches, cut fruit, cheese, small pieces of chicken, anything that can be eaten while walking around by someone too restless to sit.

Eat with them rather than watching them eat, because copying survives long after instruction stops working. Six small meals often beat three larger ones. And allow far more time than seems necessary.

Thirst perception fades, so someone can become dehydrated without ever feeling thirsty, and dehydration causes confusion, constipation, urinary infection and falls. It is frequently the cause of a sudden unexplained deterioration.

Leave a drink visibly within reach at all times and offer regularly rather than waiting to be asked. Water is not the only route: soup, jelly, fruit with high water content, ice lollies. If a cup has become difficult, a lidded cup with a straw often solves it without any conversation about needing help.

Coughing during or after eating and drinking, a wet or gurgly voice after swallowing, or food held in the mouth without being swallowed all warrant a referral for a swallowing assessment. Aspiration pneumonia is a leading cause of death in advanced dementia and this is the point at which it becomes preventable.

In late-stage dementia, appetite genuinely declines as part of the illness, and at that stage forced feeding causes distress without extending life. That is a conversation to have with a doctor, ideally alongside a hospice discussion, rather than a problem to solve at the table.
