Frontotemporal dementia (FTD), the second commonest degenerative cause of dementia under the age of 65, often presents with striking changes in behaviour and personality in association with frontal lobe atrophy. Based on the behavioural changes observed in FTD, it is commonly assumed that the orbitofrontal cortex is the earliest and most severely affected frontal sub-region. However, evidence to support this assumption has to date been largely lacking.
