Abstract
Non-pharmacological interventions can improve the behavioural and psychological symptoms of dementia (BPSD). However, the optimal non-pharmacological treatments remain controversial. This study aimed to compare the efficacy of multiple non-pharmacological methods and identify the optimal therapy for BPSD. Potential randomised controlled trials (RCTs) were searched and selected from 15 databases and sources from the inception of the databases until 1 October 2022. Two independent authors implemented study screening, data extraction, and methodological quality assessment. Primary outcome was reduction of Neuropsychiatric Inventory (NPI). The secondary outcome were changes of Cornell Scale for Depression in Dementia (CSDD), the Cohen-Mansfield Agitation Inventory (CMAI), the Quality of Life in Alzheimer's Disease (QoL-AD), the Abilities of Daily Living scale, and the Apathy Evaluation Scale. Meta-analyses were performed using STATA v15.0 and ADDIS v1.16.8. The GRADE approaches were utilised to evaluate evidence quality. The present study included 43 RCTs with 4978 participants. The global methodological quality of the RCTs was moderate. Regarding NPI reduction, with moderate-certainty evidence, exercise plus treatment as usual (TAU) outperformed TAU (mean difference [MD]: -7.13; 95% confidence interval [CI]: -13.22, -0.76) and ranked as the optimal treatment. For reduction in CSDD, with low- to moderate-certainty evidence, massage plus TAU (MD: -15.26; 95% CI: -20.13, -10.52) and music plus TAU (MD: -2.40; 95% CI: -4.62, -0.12) were associated with greater reduction compared with TAU. For reduction in CMAI, with moderate-certainty evidence, aromatherapy plus massage (MD: -15.84; 95% CI: -29.76, -2.42) and massage plus music (MD: -13.12; 95% CI: -25.43, -0.76) were significantly more effective than TAU. For improvement in QoL-AD, with critically low- to low-certainty evidence, there were no statistical differences between any of non-pharmacological treatments and TAU. Due to the limited number of included studies, network meta-analysis was not performed for other outcomes. In conclusion, non-pharmacological treatments are effective for overall symptoms, depression, and agitation. Exercise plus treatment as usual may be an optimal non-pharmacological intervention for improving the overall BPSD. This may help to guide patients, doctors, and policymakers.

Survival Bias and Crosstalk between Chronological and Behavioral Age: Age- and Genotype-Sensitivity Tests Define Behavioral Signatures in Middle-Aged, Old, and Long-Lived Mice with Normal and AD-Associated Aging. Biomedicines 2021; 9:biomedicines9060636. [PMID: 34199476 PMCID: PMC8228433 DOI: 10.3390/biomedicines9060636] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2021] [Revised: 05/23/2021] [Accepted: 05/24/2021] [Indexed: 12/18/2022] Open
Abstract
New evidence refers to a high degree of heterogeneity in normal but also Alzheimer's disease (AD) clinical and temporal patterns, increased mortality, and the need to find specific end-of-life prognosticators. This heterogeneity is scarcely explored in very old male AD mice models due to their reduced survival. In the present work, using 915 (432 APP23 and 483 C57BL/6 littermates) mice, we confirmed the better survival curves in male than female APP23 mice and respective wildtypes, providing the chance to characterize behavioral signatures in middle-aged, old, and long-lived male animals. The sensitivity of a battery of seven paradigms for comprehensive screening of motor (activity and gait analysis), neuropsychiatric and cognitive symptoms was analyzed using a cohort of 56 animals, composed of 12-, 18- and 24-month-old male APP23 mice and wildtype littermates. Most variables analyzed detected age-related differences. However, variables related to coping with stress, thigmotaxis, frailty, gait, and poor cognition better discriminated the behavioral phenotype of male APP23 mice through the three old ages compared with controls. Most importantly, non-linear age- and genotype-dependent behavioral signatures were found in long-lived animals, suggesting crosstalk between chronological and biological/behavioral ages useful to study underlying mechanisms and distinct compensations through physiological and AD-associated aging.
