Dementia Psychologist Highlights Eating Habit Changes as Early Sign of Cognitive Decline

Mood changes, memory loss, and confusion are commonly recognized signs of dementia. However, Dr. Kellyn Lee, a chartered psychologist at the University of Southampton specializing in dementia, ageing, and mental health, warns that shifts in eating habits can also be early indicators of cognitive decline.

In a recent TikTok video, Dr. Lee explained that changes in food preferences and sensory perceptions often accompany dementia. “When we think about food, we often know a person’s likes and dislikes over many years,” she said. “But dementia disrupts brain function, leading to unexpected changes. Someone who once loved fish and chips may suddenly refuse them. The tastes they enjoyed can become unpleasant, and textures that were once appealing may feel off.”

The Alzheimer’s Society agrees, noting that people with dementia may switch dietary preferences unexpectedly—vegetarians might develop a sudden craving for meat, or individuals may forget religious food restrictions. As dementia progresses, some individuals might even put inedible items such as napkins or soap into their mouths, posing further health risks.

Managing these behaviors requires awareness and care. The Alzheimer’s Society advises caregivers to keep non-food items out of reach and secure harmful substances like cleaning products to ensure safety.

Additionally, Dr. Lee highlights that people with dementia may forget they’ve eaten and ask for additional meals, which can create confusion and anxiety. To handle this, she suggests using distraction techniques. Instead of insisting they have already eaten, caregivers might say, “We can have lunch in a moment,” and gently redirect their attention to another activity.

Recognizing these subtle changes in eating behavior could provide crucial early signs of dementia, helping families and caregivers respond with understanding and appropriate support.
