Electrophysiological studies in animals have shown coordinated reactivation of neuronal ensembles during a restricted time period of behavioral inactivity that immediately followed active encoding. In the present study we directly investigated off-line processing of associative memory formation in the human brain. Subjects' regional cerebral blood flow(More)
BACKGROUND Quality of life (QoL) is increasingly used to characterize the impact of disease and the efficacy of interventions. METHODS Prospective cohort study in patients' and proxies' homes with 137 patients with dementia (age 52 to 88; Mini-Mental Status Examination (MMSE) 3 to 28) and their proxies (age 43 to 90). MMSE, Behave-AD, Geriatric Depression(More)
BACKGROUND Substituted judgment asks the proxy to decide what the patient would have decided, had he or she been competent. It is unclear whether substituted judgment of the patient's quality of life can serve as a surrogate measure in patients with dementia. METHODS 212 patients with dementia and their proxies were interviewed in their homes. Dementia(More)
The hippocampus is well known to contribute to episodic memory encoding. Here we used functional magnetic resonance imaging to investigate the hippocampal response to exponentially varying encoding demands while forming associations between faces and names. We found that only the left hippocampus exhibited a stepped modulation of neuronal activity, which(More)
BACKGROUND Increasing incidences of dementia necessitate the improvement of supportive measures for patients suffering from this disease and their proxies. Clinicians without psychiatric backgrounds and others involved in appraising the supportive needs of dementia patients, such as those who allocate nursing insurance, base their appraisals on the ability(More)
