“…The lack of an enhancement effect for the recall of words in AD may suggest a ‘picture superiority effect'. In other words, a pictorial stimulus may be dual-coded (picture generates both verbal and image codes) or may be more salient because of its perceptual distinctiveness [48,49]. However, as a limitation we did not examine the arousal levels in the study.…”

Emotional enhancement of memory (EEM) has been a well-known phenomenon which corresponds to the advantage of emotional stimuli to be better recalled than neutral ones. Previous studies suggest that aging favours recollection of positive items and this pattern is disrupted in Alzheimer's disease (AD). Emotional valence of different stimulus modalities, i.e. pictures and words, may also have an effect on each other's memory performances. However, none of these were clearly studied in AD. This study aimed to evaluate how emotional valences of simultaneously presented stimuli affected recall in healthy young (YG, n = 30), healthy elderly (HE, n = 30) participants and in patients with AD (n = 30). A battery consisting of emotional words presented on emotional pictures was developed. An analysis of a 3 (Groups) × 3 (Emotional Valence of Picture) × 3 (Emotional Valence of Word) mixed ANOVA design was carried out. Patients with AD could process emotional information similarly to healthy participants; however, they had EEM only for picture recalling. Emotional valence of the co-presented stimulus had a boosting effect both in the YG and HE, but not in AD group, especially if both of the stimuli had the same emotional valence. This study highlights the impaired EEM for verbal and preserved EEM for non-verbal declarative memory in patients with AD, the neurobiological underpinnings of which should be addressed by future studies.

“…Gist memory encourages individuals to capture meaning, or remember the essential meaning, the "substance" of information, rather than exact words, numbers, or pictures. A recent experimental study showed that gist-based conceptual processing of pictures was preserved in persons with MCI, supporting the persons to extract and use gist information [20]. Therefore, [20].…”

Objective:Community dwelling older adults with mild cognitive impairment (MCI) encounter challenges in many daily activities including medication taking. With inadequate health literacy, many of them have difficulty in understanding the instructions on drug labels and make decision on medication taking. This study aims to assess the effect of two interventions, verbal advice plus educational leaflet (VAEL) and comic books (CB), on medication taking among persons with MCI. Methods:This is a two-year multi-site longitudinal study with pre-and-post design and four-point measures (Time 1, 2, 3, and 4). Subjects were aged 60 or above, scored <22 in Chinese version of the Montreal Cognitive Assessment (MoCA), and were taking ≥ 2 drugs regularly. Health literacy was measured by the 24-item Chinese Health Literacy for Chronic Care (CHLCC) and medication adherence was measured by the 8-item Morisky Medication Adherence Scale (MMAS). Generalized Linear Mixed Models (GLMM) and Generalized Estimating Equation (GEE) were used. Results:Among the 131 subjects, the majority (62%) were females and mean age was 82.5 (SD 6.5). One-third of them received primary education (31%). Controlling age, there was a significant increase in CHLCC scores after the use of CBs (T4-T3: coefficient=2.742, p=0.003; T4-T1: coefficient=5.073, p=0.014). On the other hand, comparing to the baseline at T1 and controlling age, the chance of moving MMAS level one level higher than its original level at T4 was high (O.R.=3.316, S.E. 0.2979, 95% CI 0.650-1.747, p<0.001). Similar improvement in MMAS level was observed at T3 and T2. Conclusion:The two interventions (VAEL and CBs) seem to be a good strategy to improve health literacy and medication adherence among community dwellers with MCI. More research is warranted to support medication taking in this specific population.

“…Recent reviews have yielded evidence supporting the existence of noun naming deficits in individuals with MCI [10,14]. However, individual studies have revealed contradictory results: while some studies suggest that individuals with MCI performed significantly more poorly on the BNT than HE subjects [4,5,6,7,8,9,11,12,13], other studies did not find significant differences between the two groups [10,25,26,27,28,29,30,31,32]. These inconsistent reports about the performance on BNT in MCI can be explained by differences in the diagnostic criteria, procedural differences in the naming tasks, and the possibility that only a segment of patients with MCI has naming deficits [33].…”

Background: Naming difficulties have recently garnered more interest in elderly individuals with mild cognitive impairment (MCI). We anticipate that naming tests with the consideration of response time can provide more informative and distinct neuropsychological profiles of individuals with MCI. Methods: Naming tests were administered to 76 elderly individuals with MCI and 149 healthy elderly (HE). We analyzed the impact of MCI on naming performance and occurrence of “delayed” response. We also validated the predictive power of naming tests with a time-constrained scoring system. Results: MCI participants performed poorer on the noun naming test than HE participants (p = 0.014). MCI was significantly associated with the occurrence of “delayed” response on the noun (odds ratio [OR] = 3.57; 95% confidence interval [CI] = 1.78-7.17) and verb naming tests (OR = 4.66; 95% CI = 2.07-10.46). The time-constrained naming scores were significantly better able to distinguish the MCI from the HE group than the conventional spontaneous naming score on both the noun (p < 0.001) and verb (p = 0.002) naming tests. Conclusions: Our findings broaden the knowledge related to the naming ability in individuals with MCI, with respect to the response time. We also confirmed the validity of the naming tests by applying the “delayed” responses as supplementary assessments in the diagnosis of MCI.
