Role of depressive symptoms in subjective memory complaint in older adults with mild cognitive impairment

ABSTRACTBackground:Alteration in energy expenditure or metabolism is the most accused risk issue for the onset and for the course of neurodegenerative cognitive disorders. Neuropeptides are suggested to be related with learning and memory. Phoenixin (PNX) is the most recently reported neuropeptide and we aimed to compare the plasma level in people with subjective memory complaints, patients with mild cognitive impairment, and mild Alzheimer's disease (AD).Methods:Ninety two participants enrolled in the study. After screening tests, all participants were assessed with a neuropsychological battery for further cognitive evaluations. We used ELISA kit to assay the level of Human PNX.Results:Patients with AD were significantly older than people in subjective memory complaint group (p = 0.02). There was no significant difference between groups according to gender (p = 0.435). Mean plasma PNX level was not significantly different between groups (p = 0.279). Mean plasma PNX level in MCI group was positively correlated with BMI (r = 0.402 and p = 0.028), serum HDL level (r = 0.454 and p = 0.012), blood systolic pressure (r = 0.428 and p = 0.018) and negatively correlated with logical memory (r=−0.335 and p=0.031). The mean plasma PNX level was positively correlated with immediate recall in subjective memory complaint group (r = 0.417 and p = 0.034).Conclusion:This study is the first studying the association of plasma PNX level and cognitive complaints or decline. The knowledge about the role, interaction, and physiological functions of PNX is lacking. Lower plasma PNX level might be important in prodromal stages as MCI and the predictive role of PNX should be investigated in further studies.

Background: 10%to 20%of Americans aged 65 and older have mild cognitive impairment (MCI) with 10%progressing to Alzheimer’s disease (AD) each year. Underserved groups, including African Americans (AAs), are among the most vulnerable to MCI and AD. Although evidence continues to amass, the benefits of exercise and movement for AD is still understudied in AD. Objective: Understanding the attitudes, perceptions, and beliefs about motor-cognitive integration and examining the physical activity of a sample of predominantly Black women community members with self-reported memory problems will allow improved recruitment and refinement of multimodal interventions designed to improve motor-cognitive and cognitive function. Methods: We conducted focus groups with older adults who reported subjective memory complaints (n = 15; Black: n = 12, White: n = 3, mean age 71.7±5.8). Results: Findings from thematic analysis showed most participants knew of benefits of exercise. However, most participants reported not getting adequate exercise due to factors such as pain, increased responsibilities, and fears of injury. Despite barriers, participants expressed enthusiasm for multimodal interventions designed to target body and brain health and provided several suggestions to improve or enhance the proposed interventions. Conclusion: Results provide useful insights regarding improving participation among historically under-represented groups in clinical movement-based research. Participants’ discussion focused primarily on the way motor-cognitive integration prevents falls, maintains memory, and provides a social benefit. The reported perceived benefits and limitations of exercise, as this population understands it, can help researchers and physicians better engage the community for lifestyle changes that will support greater motor-cognitive health.

Objective: To determine the effects of group exercises on balance, mobility, and depressive symptoms in community-dwelling older adults with mild cognitive impairment. Design: Single blinded, randomized, matched pairs clinical trial. Setting: Four primary healthcare units. Subjects: Fifty-two sedentary subjects with mild cognitive impairment were paired (age, sex, body mass index, and Addenbrooke’s Cognitive Examination Revised score), tested, and then randomized into an intervention group ( n = 26) and a control group ( n = 26). Intervention: The intervention group performed strength (ankle weights, elastic bands, and dumbbells) and aerobic exercises (walking) in their communities’ public spaces, twice a week (60 minutes each), during 24 weeks. The control group maintained its usual routine. Main measures: Balance (Berg Balance Scale (BBS)), mobility (Timed Up and Go Test (TUG)), and depressive symptoms (Geriatric Depression Scale-15) were assessed before and after the intervention. Results: Before the intervention, the two groups did not differ statistically. After, the intervention group showed significant improvement ( P < 0.05) in balance (before: 53 ± 3; after: 55.1 ± 1.1 points), mobility (before: 10.7 ± 2.9 seconds; after: 8.3 ± 2 seconds), and depressive symptoms (median punctuation (interquartile range) before: 4 (1.8–6); after: 2.5 (1–4)). The control group presented a significant increase in their depressive symptoms (median before: 3.5 (2–7.3); after: 4 (2–5.3)), while their balance and mobility showed no significant modification. Small effect sizes were observed in the intervention group and control group depressive symptoms, as well as in the control group’s mobility and balance. Large effect sizes were observed the intervention group’s mobility and balance. Conclusion: Group exercises improved balance, mobility, and depressive symptoms in community-dwelling older adults with mild cognitive impairment.
