 The refusal to continue a given task and leave the behavior-testing laboratory, known as running-away behavior, is a typical symptom of frontotemporal dementia(FTD). Similar behavior is also observed in advanced Alzheimer's disease(AD). However, when trying to leave, AD patients hold the door knob of the laboratory, attempt opening the door, but often fail to open it. This is in contrast to observations with FTD patients, who do not show difficulty in opening the door. These facts lead to a hypothesis that there is a difference in the frequency and severity of the disability to open a door, between patients with advanced AD and FTD. In this study, we examined the hypothesis and explored the factors related to disturbance in door opening. FTD patients can easily open a door compared with AD patients. This may be relative to the relatively preserved function of the parieto-occipital region in the FTD patients, which is suggested by the better scores for constructional tasks in FTD patients than in AD patients.
