Abstract
SUMMARYA 64‐year‐old man presented with a change in personality and behaviour but with no neurological deficits. He exhibited impaired executive functions, apathy, unsteadiness of gait and falling; he lacked insight and exhibited purposeless behaviour, making loud grunting noises. A CT scan at 6 months revealed no abnormality, but at 9 months CT and MRI showed a bilateral thalamic tumour. The presenting symptoms had similarities to frontal lobe dysfunction progressing to dementia.
