The Alzheimer’s Society says that sudden cravings for certain types of foods can, in some cases, be an early sign of dementia. The charity highlights that changes in appetite or eating behaviour—especially newly developing strong preferences—may reflect underlying changes in the brain rather than normal dietary shifts. It notes that people may begin to seek foods that are sweet, fatty, or high in carbohydrates. The charity links this pattern to conditions that affect behaviour and decision-making, including frontotemporal dementia, where eating habits can change early. The reports emphasize that cravings alone do not confirm a diagnosis and that persistent or noticeable changes in a person’s behaviour should be discussed with a healthcare professional. They also indicate that dementia is a broad group of conditions with different symptoms, and appetite changes are only one possible indicator among many. Overall, the message is that unusual, sudden changes in what someone craves—particularly if they are out of character—should prompt further assessment rather than being dismissed.
