Background: Older adults with type 2 diabetes mellitus (DM2) exhibit accelerated decline in some domains of cognition, including verbal episodic memory. Few studies have investigated the influence of DM2 status in older adults on recognition memory for more complex stimuli,
such as faces. Aims: In the present study, we sought to compare recognition memory performance for words, objects and faces under conditions of relatively low and high
cognitive load. Methods: Healthy older adults with good glucoregulatory control (n = 13) and older adults with DM2 (n = 24) were administered recognition memory tasks in which stimuli (faces, objects and words) were presented under conditions of either i) low (stimulus presented without a background pattern), or ii) high (stimulus presented against a background pattern) cognitive load. Results: In a subsequent recognition phase, the DM2 group recognised fewer faces than healthy controls. Further, the DM2 group exhibited word recognition deficits in the low cognitive load condition. Conclusions: The recognition memory impairment observed in the patients with DM2 has clear implications for day-to-day functioning. While these deficits were not amplified under conditions of increased cognitive load, the present study emphasises that recognition memory impairment for both words and more complex stimuli, such as faces, are a feature of DM2 in older adults.
