We examined, with single photon emission tomography (SPECT) and (99mTc)-HMPAO, 18 patients with idiopathic Parkinson's disease and no dementia (PD), 12 patients with PD and dementia, 24 patients with probable Alzheimer's disease (AD), and 14 controls. While the three patient groups showed significantly lower perfusion in frontal inferior and temporal inferior areas as compared to controls, both demented groups showed significantly more severe bilateral hypoperfusion in superior frontal, superior temporal and parietal areas as compared to non-demented PD patients and controls. On the other hand, no significant differences in cerebral perfusion were found between patients with AD and patients with PD and dementia. In conclusion, our findings demonstrated specific but similar cerebral perfusion deficits in demented patients with either AD or PD.

This study examined how future self-representations are affected by two different chronic illnesses, one focused on cognitive losses, early-stage Alzheimer's disease (AD), and one focused on physical losses, Parkinson's disease (PD). The impact of illness on possible selves (perceptions of self in the future) was made salient by a comparison with healthy older adults in order to better understand developmental issues in later life. Findings show that although there were no differences in the total number of domains reported by the groups, specific domains were reported differently by patient groups and all domains were likely to become infused with illness. As expected, patient groups had less self-efficacy and lower outcome expectancies for their future selves, and PD patients reported less distance from their feared selves. Although these findings are intuitive, this is the first empirical effort to document the impact of illness on older adults' self-representations. Group differences are explained in terms of disease context, and the importance of possible selves and self-regulatory functions as therapeutic mechanisms for adaptation to illness are emphasised.
