[Cognitive and mnemonic information processing in institutionalized and noninstitutionalized elderly patients].

Older subjects (institutionalized in a home for the aged and non-institutionalized) were compared in a test battery according to the recommendations of the NINCDS-ADRA. The institutionalized subjects were not distinguishable from the controls when only a small amount of information was to be processed or when the information had to be recalled with no distraction. Possible reasons for the observed differences are discussed.
