Sour aversion in frontotemporal dementia: a case report and review on physiologic-anatomic mechanisms

ABSTRACT

Frontotemporal dementia (FTD) is a common cause of early-onset dementia characterized by behavioral and personality changes, as well as, altered eating habits. FTD is associated with complex changes in neural networks of gustatory processing which may be responsible for eating abnormalities. Here, we present a 66-years-old lady suffered from behavioral variant of FTD with an interesting symptom of food aversion, typically sour foods.
