Abstract:
The study of the self in neuropsychological patients raises not only theoretical questions on the relationships between the self, autobiographical memory (AM), and episodic future thinking but also clinical issues for patients' daily life and care. We addressed this issue in Parkinson's disease patients for whom AM and future thinking impairments have been documented. All patients and controls generated and dated up past and future self-images and provided associated past and future events. Our findings suggest a subtle pattern of preservation/impairment of different dimensions (quantitative and qualitative) of self-images, which rely partially on the episodic quality of past and future events.
