title: Memory dysfunction of the frontal type in normal ageing.
abstract: In this study healthy subjects divided into five consecutive age groups (20-60 years of age) completed a series of memory tasks which had previously been shown to reveal impairments in patients with frontal lobe lesions. Significant age differences were found for free recall, retention rates for material which required effortful encoding, memory for temporal order and prospective memory. In the tests addressing these memory functions, subjects of more than 60 years of age performed more poorly than the youngest group, and they also showed evidence of false recognition (increased false alarm rates and confabulatory responses). The general pattern suggests that inefficient frontal functioning might contribute to age-related memory problems.
