<b><i>Introduction:</i></b> Subjective memory complaints (SMCs) among stroke patients are common. To date, reports on SMCs using the Subjective Memory Complaint Questionnaire (SMCQ) are limited. We provided descriptive information on SMCs using the SMCQ alongside objective neuropsychological function assessment in stroke patients and established the sensitivity of SMCQ for post-stroke dementia. <b><i>Methods:</i></b> In total, 419 consecutive stroke patients who were admitted to a stroke unit for younger populations (age &#x3c;65 years) at a rehabilitation hospital from June 1, 2014, to January 1, 2020, were reviewed. SMCs were measured using the SMCQ. Objective neuropsychological function was assessed using protocols of the Vascular Cognitive Impairment Harmonization Standards. <b><i>Results:</i></b> SMCs were significantly correlated with objective neuropsychological functions including memory, executive function, language, and depression. SMCs were not significantly correlated with visuospatial function. The SMCQ exhibited comparable sensitivity to that of Mini-Mental Status Examination for evaluating post-stroke dementia. <b><i>Conclusions:</i></b> The SMCQ may be a valid measure of cognitive function among patients with stroke, is sensitive for post-stroke dementia, and may assume a complementary role for assessing patients with stroke.

The Relationship

ABSTRACTBackground:Subjective memory complaints are a requirement in the diagnosis of mild cognitive impairment (MCI) as they are thought to indicate a decline in objective memory performance. However, recent research suggests that the relationship between subjective memory complaint and objective memory impairment is less clear. Thus, it is possible that many people without subjective memory complaints who develop Alzheimer's disease are precluded from a diagnosis of MCI.Methods:The present study examined the relationship between subjective memory complaint assessed using the Multifactorial Memory Questionnaire (MMQ) and objective memory impairment assessed using standard neuropsychological measures in cases of amnestic MCI (n= 48), non-amnestic MCI (n= 27), and unimpaired healthy participants (n= 64).Results:Correlational and regression analyses indicated that subjective memory complaints displayed a poor relationship with objective memory performance. A subsequent discriminant function analysis indicated that subjective memory complaints failed to improve the diagnostic accuracy of MCI and resulted in increased rates of false negative and false positive diagnoses.Conclusion:The results of the present study suggest that a diagnostic criterion of subjective memory complaint reduces the accuracy of MCI diagnosis, resulting in an elevated rate of false positive and false negative diagnoses. The results of this study in conjunction with recent research indicate that a criterion of subjective memory complaint should be discarded from emerging diagnostic criteria for MCI.

Subjective Memory Complaint

Abstract Background Subjective memory complaint (SMCs) is a common trait amongst older population. The subjective cognition about their memory could depend on objective cognition. The aim of the current study was to examine the interaction between subjective memory cognition (i.e., SMC) and objective cognition on cognitive functions in participants from older generation. Methods A total of 219 patients, 181 normal control (NC) patients and 38 patients with mild cognitive impairment (MCI), were examined through standardized and comprehensive clinical evaluation and neuropsychological assessment. The Subjective Memory Complaints Questionnaire was used to assess SMCs along with five cognitive tasks were used to evaluate cognitive decline over following areas: verbal memory, visuospatial memory, attention, fluency, and language. Results The results of 2 × 2 two-way analysis of variance (ANOVA) showed that there were significant interactions between SMCs and cognitive status (NC, MCI) on memory performances. NC with SMCs showed significantly lower performance in verbal memory and visuospatial memory compared to NCs without SMCs. Conversely, no effect was observed in the MCI group. Conclusion There are interactions between subjective cognition (i.e., SMC) and objective cognition (i.e., cognitive status) on memory performances in older adults. The roles of SMCs on memory performances should be interpreted with older adults’ objective cognitive status.

Objective: Subjective memory complaints (SMCs) are associated with mild cognitive impairment and dementia but are understudied in African Americans (AAs). We compared SMC endorsement in white and AA participants and evaluated predictors of diagnostic progression. Methods: Initial visit variables, including SMC and memory performance, were compared within a cognitively normal race-matched sample of white and AA participants ( N total = 912; 456each race) to assess the presence and predictors of SMC, the predictors of future diagnostic progression, and the change in memory performance over time. Results: More white (32.9%) than AA (24.3%) participants reported SMC ( P < .01, ϕ = −.10). Subjective memory complaint was predicted by memory performance ( B = −0.03, standard error [SE] = 0.013, odds ratio [OR] = .968, P < .05) and race ( B = −0.99, SE = 0.080, OR = .373, P < .001). Subjective memory complaints and memory performance were associated with progression, χ2 (3, n = 912) = 102.37, P < .001. African American race (−2.05 ± 0.24 SE) and SMC (−0.45 ± 0.21 SE) were associated with worse memory performance at baseline and over time, χ 2(3) = 13.54, P < .01. Conclusions: In contrast to previous research, our study found that SMC is associated with diagnostic progression and objective memory declines in both white and AA participants.

Facial Emotion Processing

AbstractSubjective memory complaints (SMCs) are commonly related to aging, but they are also presented by young adults. Their neurophysiological mechanisms are not thoroughly understood, although some aspects related to affective state have been mentioned. Here, we investigated whether facial emotion processing is different in young people with (n = 41) and without (n = 39) SMCs who were exposed to positive, negative, and neutral faces, by recording the event-related potential (ERP) activity. From the ERP activity, the N170 (an index of face processing) and the LPP (an index of motivated attention) components were extracted. Regarding the N170, results showed less amplitude for positive and neutral faces in the participants with SMCs than in those without SMCs. Moreover, women with SMCs displayed longer latencies for neutral faces than women without SMCs. No significant differences were found between the groups in the LPP component. Together, our findings suggest deficits in an early stage of facial emotion processing in young people with SMCs, and they emphasize the importance of further examining affective dimensions.

Background: The three-month, multidomain Memory Boot Camp program incorporates z-score neurofeedback (NFB), heart rate variability (HRV) biofeedback, and one-on-one coaching to teach memory skills and encourage behavior change in diet, sleep, physical fitness, and stress reduction. Objective: This prospective trial evaluates the Memory Boot Camp program for adults ages 55 to 85 with symptoms of Mild Cognitive Impairment (MCI) and subjective memory complaints. Methods: Participants were evaluated via the Montreal Cognitive Assessment (MoCA), NeuroTrax Global Cognitive Index, measures of anxiety, depression, sleep, quality of life, quantitative electroencephalography (QEEG), and HRV parameters at four timepoints: baseline, pre-program, post-program, and follow-up. The trial included a three-month waiting period between baseline and pre-program, such that each participant acted as their own control, and follow-up took place six months after completion of the program. Results: Participants’ MoCA scores and self-reported measures of anxiety, depression, sleep quality, and quality of life improved after treatment, and these changes were maintained at follow-up. Physiological changes in HRV parameters after treatment were not significant, however, breathing rate and QEEG parameters were improved at post-program and maintained at follow-up. Finally, participants’ improvement in MoCA score over the treatment period was correlated with their improvement in two brain oscillation parameters targeted by the z-score NFB protocol: relative power of delta and relative power of theta. Conclusions: Trial results suggest that the Memory Boot Camp program is a promising treatment strategy for older adults with symptoms of MCI and subjective memory complaints.
