FTLD patients binge eat, especially sweets, even when stated that they are full. Investigators found significant atrophy in ventral insula, rostral orbital frontal, and striatum of right hemisphere among six binge eaters. Interestingly other frontal lobe abnormalities on neuropsychological tests were not found. Also they did not gain weight, leading Grossman to question whether the eating was a form of L'Hermitte's environmental dependency.
