Cognitive and neuropsychological aspects of age-associated memory dysfunction
Umeå University, Faculty of Social Sciences, Department of Psychology.
1991 (English)Doctoral thesis, comprehensive summary (Other academic)
Abstract [en]

Memory dysfunction is common in association with the course of normal aging. Memory dysfunction is also obligatory in age-associated neurological disorders, such as Alzheimer’s disease. However, despite the ubiquitousness of age-related memory decline, several basic questions regarding this entity remain unanswered. The present investigation addressed two such questions: (1) Can individuals suffering from memory dysfunction due to aging and amnesia due to Alzheimer’s disease improve memory performance if contextual support is provided at the time of acquisition of to-be- remembered material or reproduction of to-be-remembered material? (2) Are memory deficits observed in ‘younger’ older adults similar to the deficits observed in ‘older’ elderly subjects, Alzheimer’s disease, and memory dysfunction in younger subjects?

The outcome of this investigation suggests an affirmative answer to the first question. Given appropriate support at encoding and retrieval, even densely amnesic patients can improve their memory performance. As to the second question, a more complex pattern emerges. When attentional demands are varied, subjects of varying ages perform qualitatively similar. However, when semantic aspects of the to-be- remembered material are manipulated, age-associated qualitative differences are observed. These qualitative differences show up between older and younger adults, as well as between ‘younger’ and ‘older’ elderly subjects.
