The efficacy and safety of Chinese herbal medicine for mild cognitive impairment: a systematic review and meta-analysis of randomized placebo-controlled trials. Front Pharmacol 2024; 15:1341074. [PMID: 38425647 PMCID: PMC10902497 DOI: 10.3389/fphar.2024.1341074] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2023] [Accepted: 01/29/2024] [Indexed: 03/02/2024] Open
Abstract
Objective: Effective and safe treatments for mild cognitive impairment (MCI) are limited. Chinese herbal medicine (CHM) is commonly used in China to manage MCI. However, its efficacy and safety remain uncertain. This review aims to evaluate the efficacy and safety of CHM for MCI. Methods: Nine databases were searched from their inceptions to January 2023. Randomized, placebo-controlled trials of oral CHM for MCI were included. Study quality was assessed using the Cochrane risk-of-bias tool 2.0, and the certainty of evidence was evaluated via the GRADE approach. Results: Thirteen studies, involving 1,043 participants, were analyzed. Most of the studies (10 out of 13) were associated with "some concerns" regarding the overall risk of bias. Meta-analyses results indicated that CHM significantly improved cognitive function compared to placebo in terms of Mini-Mental State Examination (MMSE) (MD: 1.90 [1.22, 2.58], I2 = 87%, 11 studies, 823 participants) and Montreal Cognitive Assessment (MoCA) (MD: 2.88 [1.69, 4.06], I2 = 81%, 3 studies, 241 participants). The certainty of evidence for MMSE was assessed as "moderate", while it was "low" for MoCA. One study did not report adverse events (AEs), one study reported no statistical difference between the groups in terms of AEs, and 11 studies provided detailed numbers of AE cases where gastrointestinal symptoms were the most commonly reported AEs. Two studies reported no SAEs among participants and one study found no significant difference in SAEs proportions between groups. The meta-analysis revealed no significant difference in AEs between the two groups (RR: 1.31 [0.92, 1.87), I2 = 0%, 11 studies, 839 participants). The cognitive-enhancing function of commonly used herbs (Panax ginseng C.A.Mey., Acorus calamus var. angustatus Besser, and Polygala tenuifolia Willd.) may be attributed to mechanisms including antioxidant, anti-apoptotic, anti-neurotoxic, anti-cytotoxic, and anti-inflammatory actions. Conclusion: Chinese herbal medicine holds potential as an effective intervention to improve cognitive function in MCI patients, supported by meta-analyses evidence of low to moderate certainty. Although current data suggests CHM is generally safe, caution is advised due to the lack of AE reporting or detailed information in some instances.

Joubran K, Bar-Haim S, Shmuelof L. The functional and structural neural correlates of dynamic balance impairment and recovery in persons with acquired brain injury. Sci Rep 2022; 12:7990. [PMID: 35568728 PMCID: PMC9107482 DOI: 10.1038/s41598-022-12123-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2021] [Accepted: 05/03/2022] [Indexed: 12/29/2022] Open
Abstract
Dynamic balance control is associated with the function of multiple brain networks and is impaired following Acquired Brain Injury (ABI). This study aims to characterize the functional and structural correlates of ABI-induced dynamic balance impairments and recovery following a rehabilitation treatment. Thirty-one chronic participants with ABI participated in a novel rehabilitation treatment composed of 22 sessions of a perturbation-based rehabilitation training. Dynamic balance was assessed using the Community Balance and Mobility scale (CB&M) and the 10-Meter Walking Test (10MWT). Brain function was estimated using resting-state fMRI imaging that was analysed using independent component analysis (ICA), and regions-of-interest analyses. Brain morphology was also assessed using structural MRI. ICA revealed a reduction in component-related activation within the sensorimotor and cerebellar networks post-intervention. Improvement in CB&M scale was associated with a reduction in FC within the cerebellar network and with baseline FC within the cerebellar-putamen and cerebellar-thalamic networks. Improvement in 10MWT was associated with baseline FC within the cerebellar-putamen and cerebellar-cortical networks. Brain volume analysis did not reveal structural correlates of dynamic balance, but dynamic balance was correlated with time since injury. Our results show that dynamic balance recovery is associated with FC reduction within and between the cerebellar and sensorimotor networks. The lack of global structural correlates of dynamic balance may point to the involvement of specific networks in balance control.

Abstract
Background: The Montreal Cognitive Assessment (MoCA) is a standard test for screening and monitoring cognitive functions. Objective: This study explored the two-year changes in MoCA scores in older adults. Methods: Fifty-seven participants with mild cognitive impairment (MCI) and 87 participants with normal cognition completed the baseline and two-year follow-up assessments. Apart from MoCA, tests on visuospatial judgment, memory, and motor-related executive function were administered. Results: The results identified three MCI subgroups based on the differential changes in MoCA scores. They were the consistently low, consistently high, and low-to-high between-time performances. These heterogeneous test performances are on contrary to the significant deteriorations in executive function and finger dexterity across all subgroups. Repeated exposure to MoCA tests during the follow-up period was found to be a plausible indicator of the MCI subgroup categorization. Conclusion: Findings raise concerns over adopting brief clinical instrument for repeated testing, such as MoCA, for monitoring MCI conditions among older adults.

Minimal Clinically Important Difference of Executive Function Performance in Older Adults Who Fall: A Secondary Analysis of a Randomized Controlled Trial. Gerontology 2021; 68:771-779.

Abstract
INTRODUCTION Executive function is responsive to exercise and predictive of subsequent falls. Minimal clinically important differences (MCIDs) are critical for understanding whether observed changes are meaningful. However, MCIDs of many cognitive measures are not established. We aimed to determine MCIDs of the Digit Symbol Substitution Test ([DSST] processing speed measure), Stroop (inhibition measure), and Trail Making Test B-A (TMT; set-shifting measure), using anchor- and distribution-based approaches in older adults who have fallen and received the Otago Exercise Program (OEP) relative to usual care only (CON). Our secondary aim was to establish construct (convergent and divergent) validity of these measures. METHODS Complete case analyses of cognitive outcomes (DSST, Stroop, TMT, and Montreal Cognitive Assessment [MoCA]) were acquired at baseline and 1 year (NCT01029171; NCT003235960); participants were randomized to the OEP (n = 114/172; Age: 80.6 ± 6.1 years; 64.9% Female) or CON (n = 128/172; Age: 82.3 ± 5.8 years; 71.9% Female)]. The MoCA was used as the anchor. We estimated MCIDs using anchor- and distribution-based approaches. Anchor-based executive function change differences ([CD] 1 year minus baseline) observed in participants with meaningful changes in the MoCA (≥3 or ≤ -3 points) receiving the OEP were subtracted from the CON. An anchor-based receiver operator characteristic (ROC) curve was employed to identify optimal cut-off scores of the 3 executive function measures. The distribution-based approach (DA) accounted for variability in baseline and follow-up data. MCID ranges were estimated using these approaches. We used Spearman's correlations to explore convergent validity between executive function measures and other measures involving the same construct (DSST, Stroop, TMT, MoCA, and Mini-Mental State Examination), and divergent validity between executive function measures and variables reflecting different constructs (Geriatric Depression Scale, Instrumental Activities of Daily Living, sex, and body mass index). RESULTS Based on the 3 approaches, MCID improvement ranges were 3-5 symbols for the DSST (CD = 5; ROC = 2.5; DA = 3.3 symbols), and -11.5 to -26.0 s for the Stroop (CD = -26.0; ROC = -11.5; DA = -20.6 s). MCID decline ranges were -3 to -6 symbols for the DSST (CD = -5.2; ROC = -2.5; DA = -3.3 symbols) and 5.4-30.6 s for the Stroop (CD = 30.6; ROC = 5.4; DA = 20.6 s). MCIDs for the TMT were not meaningful due to high variability (Improvement: CD = -106.6; ROC = -18.4; DA = -69.1 s; Decline: CD = 69.1; ROC = 14.5; DA = 69.1 s). The executive function measures exhibited good convergent (r = -0.22 to r = 0.42) and divergent (r < -0.01 to r = 0.16) validity. CONCLUSIONS These established MCIDs will allow clinicians to interpret meaningful changes in executive function following exercise amongst older adults who have fallen. The DSST, Stroop, and TMT demonstrated good construct validity, supporting their use in comprehensive fall-risk assessments in older adults who fall.

Abstract
Introduction Major trauma centres are effective in reducing morbidity and mortality rates following serious injury. Many patients attending major trauma centres present with traumatic brain injuries, requiring specialist assessment in screening for potential cognitive deficits. Numerous cognitive screens exist but it is currently unclear which are used most frequently within major trauma centres. This study aimed to identify which screening tools are used most frequently in major trauma centres in England to enable discussion around their suitability for this clinical population. Method Electronic surveys were distributed via a mailing list to Clinical Psychologists and Clinical Neuropsychologists in major trauma centres across England to gather data on the use of cognitive screens. Results Fourteen Clinical Psychologists in Neuropsychology participated. Results suggest major trauma centres in England are currently using the ACE-III (50%) or MoCA (42%) as the most frequently used screens for cognitive difficulties following traumatic brain injury. Cognitive screening pathways are multi-disciplinary involving OTs (86%), psychologists (qualified 79%; assistant 57%) psychiatrists (36%), mental health nurses (7%) and therapy assistants (7%). Conclusions Major trauma centres are using evidence-based cognitive screens at present, but further work is needed to develop more effective, better validated cognitive screens for traumatic brain injury populations. Increased inter-professional discussion on the practice of cognitive screening would be beneficial for patients seen within major trauma centres.

Effect of mirabegron on cognitive function in elderly patients with overactive bladder: MoCA results from a phase 4 randomized, placebo-controlled study (PILLAR). BMC Geriatr 2020; 20:109. [PMID: 32183741 PMCID: PMC7079371 DOI: 10.1186/s12877-020-1474-7] [Citation(s) in RCA: 37] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2019] [Accepted: 02/14/2020] [Indexed: 12/02/2022] Open
Abstract
Background Antimuscarinics are often used for treatment of overactive bladder (OAB), but exposure to medications such as antimuscarinics that have anticholinergic properties has been linked to adverse cognitive effects. A phase 4 placebo-controlled study (PILLAR; NCT02216214) described the efficacy and safety of mirabegron, a β3-adrenoreceptor agonist, for treatment of wet OAB in patients aged ≥65 years. This pre-planned analysis aimed to measure differences in cognitive function between mirabegron and placebo, using a rapid screening instrument for mild cognitive impairment: the Montreal Cognitive Assessment (MoCA). Methods Outpatients aged ≥65 years with wet OAB were randomized 1:1 to mirabegron or placebo, stratified by age (<75/≥75 years). There were no exclusion criteria regarding cognitive status. Patients randomized to mirabegron initially received 25 mg/day with an optional increase to 50 mg/day after week 4/8 based on patient/investigator discretion. The MoCA was administered at baseline and end of treatment (EoT, week 12). The study protocol was Independent Ethics Committee/Institutional Review Board-approved. Results Of the 887 randomized patients who received ≥1 dose of study drug, 72.3% were female, 79.5% were white, and 28.1% were aged ≥75 years. All patients had ≥1 comorbidity and 94.3% were receiving ≥1 concomitant medication. One third of patients had a history of psychiatric disorders, the most common being depression (17.2%), insomnia (15.7%), and anxiety (11.4%). Baseline mean (standard error, SE) MoCA total scores were 26.9 (0.1) and 26.8 (0.1) in the mirabegron and placebo groups, respectively. Among patients with MoCA data available at baseline/EoT, 27.1% (115/425) and 25.8% (106/411) of mirabegron and placebo group patients, respectively, had impaired cognitive function at baseline (MoCA total score <26). There was no statistically significant change in adjusted mean (SE) MoCA total score from baseline to EoT in the mirabegron group (−0.2 [0.1]) or the placebo group (−0.1 [0.1]). Conclusions Treatment with mirabegron for 12 weeks did not contribute to drug-related cognitive side effects in patients aged ≥65 years, as measured by the MoCA. Furthermore, the pattern of change in cognition over time in an older OAB trial population does not appear to differ from that of subjects receiving placebo. Trial registration NCT02216214 (prospectively registered August 13, 2014).

Abstract
OBJECTIVE To assess the value of using frailty measures in primary care for predicting death, nursing home transfer (NHT) and hospital admission. DESIGN Cohort study. SETTING AND PARTICIPANTS All 380 people, mean age 88.4, living in the community and receiving home-based primary geriatric care from one practice in Victoria, Canada. INTERVENTIONS/MEASUREMENTS A 60 min baseline assessment which included: Clinical Frailty Scale (CFS), EuroQol EQ-5D-5L (EQ-5D), EuroQol Visual Analogue Scale (EQ-VAS) and Gait Speed (Gaitspeed). OUTCOMES Death, NHT and hospital admission. RESULTS During 18 months of follow-up, there were 39 (10.3%) deaths, 48 (12.6%) NHTs and 93 (24.5%) individuals admitted to hospital. All three outcomes were predicted by: CFS Level 6+7/4+5 (HR death 5.92, 95% CI 3.12 to 11.22, NHT 6.00, 95% CI 3.37 to 10.66 and hospital admission 2.92, 95% CI 1.93 to 4.40); EQ-5D Quintile 1/Quintile 5 (death 6.26, 95% CI 2.11 to 18.62; NHT 3.18, 95% CI 1.29 to 7.82 and hospital admission 2.94, 95% CI 1.47 to 5.87); EQ-VAS Q1/Q5 (death 7.0, 95% CI 2.34 to 20.93; NHT 3.38, 95% CI 1.22 to 9.35 and hospital admission 6.69, 95% CI 3.20 to 13.99) and Gaitspeed (death 5.87, 95% CI 1.78 to 19.34; NHT 8.51, 95% CI 3.18 to 22.79 and hospital admission 11.05, 95% CI 5.45 to 22.40). Medical diagnoses, multiple comorbidities and polypharmacy were weaker predictors of these outcomes. Cox regression analyses showed CFS (adjusted HR 2.88, 95% CI 1.23 to 6.68), EQ-VAS (0.96, 95% CI 0.93 to 0.98), estimated glomerular filtration rate (0.97, 95% CI 0.95 to 1.00) and haemoglobin (0.97, 95% CI 0.94 to 0.99) were independently associated with death. Gaitspeed (0.13, 95% CI 0.03 to 0.57), Geriatric Depression Scale (1.39, 95% CI 1.07 to 1.82) and dementia diagnosis (4.61, 95% CI 1.86 to 11.44) were associated with NHT. Only CFS (1.75, 95% CI 1.21 to 2.51) and EQ-VAS (0.98, 95% CI 0.96 to 0.99) were associated with hospital admission. No other diagnoses, polypharmacy nor multiple comorbidities predicted these outcomes. CONCLUSIONS For elderly people, standardised simple measures of frailty and health status were stronger predictors of death, NHT and hospital admission than medical diagnoses. Consideration should be given to adding these measures into usual medical care for this age group.

Abstract
Patients with traumatic brain injury (TBI) undergo cognitive impairment. We aimed to explore the cognition level in patients of all severities with different lesion sites and the effect of demographic variables, lesion site, TBI severity, and the time since the TBI on their cognitive abilities using the Montreal Cognitive Assessment-Basic (MoCA-B). A total of 67 patients with TBI were recruited from the Department of Cerebral Surgery at No. 101 Hospital of the Chinese People's Liberation Army (PLA) at out-patient follow up. A regression model was performed to assess the effect of these variables on cognition of TBI patients. As expected, age, education, and the Glasgow Coma Scale (GCS) score were found as predictors of cognition of TBI patients. Participants, who were younger, had more years of education, and a higher GCS score had better cognition, respectively. Thus, the results provide evidence for the early detection of possible different cognition impairment of TBI patients. Specifically, these findings can help predict early prognosis for patients in the course of clinical diagnosis and treatment and, thus, allow for early intervention to improve the patients' quality of life and possible extend their life.

Abstract
Objective Persons with stroke frequently suffer from cognitive impairment. The Montreal Cognitive Assessment (MoCA), a recently developed screening tool, is sensitive to poststroke cognitive deficits. The present study assessed its psychometric and clinimetric properties (i.e., responsiveness, minimal clinically important difference (MCID), and criterion validity) in stroke survivors receiving rehabilitative therapy. Method The MoCA and the Stroke Impact Scale (SIS) were administered to 65 stroke survivors before and after 4 to 5 weeks of therapy. The effect size and standardized response mean (SRM) were calculated for responsiveness. Anchor- and distribution-based methods were used to estimate the MCID. Criterion validity was measured with the Spearman correlation coefficient. Results The responsiveness of the MoCA was moderate (SRM = 0.67). Participants exceeding the MCID according to the anchor- and distribution-based approaches were 33 (50.77%) and 20 (30.77%), respectively. Fair to good concurrent validity was reported between the MoCA and the SIS communication subscale. The MoCA had satisfactory predictive validity with the SIS communication and memory subscales. Conclusion This study may support the responsiveness, MCID, and criterion validity of the MoCA in stroke populations. Future studies with larger sample sizes are needed to validate the current findings.

Abstract
Background: Mild cognitive impairment (MCI) prevalence is estimated at 6%-12% of the population. It is possible that early treatment at the MCI stage could reduce progression to more severe cognitive impairment. The Montreal Cognitive Assessment (MoCA) is a sensitive measure used to assess changes in cognitive function. Various Chinese herbal medicines (CHMs) have been tested for effects on MCI using MoCA. Objectives: To evaluate the clinical evidence for CHMs on MoCA scores in MCI. Design: Five biomedical databases in English and Chinese language were searched for randomized controlled trials that compared orally administered CHMs with a control group and assessed changes in cognition using MoCA. Analyses were based on the comparison, control intervention, and study duration. Mean differences and 95% confidence intervals were calculated to evaluate treatment effects. For each study, risk of bias was assessed according to the Cochrane tool. Results: Nineteen studies were included with 16 contributing to the data analyses. Three studies were placebo controlled. Nine compared a CHM with a pharmacotherapy, three combined a CHM with a pharmacotherapy, and one combined CHM with cognitive training. In the two placebo-controlled studies of 24-week duration, results favored the CHMs at end of treatment. Conclusions: The systematic review suggests that the oral application of certain CHMs improved scores on MoCA by 1.76-2.34 points compared with placebo in people with MCI after 24 weeks of treatment. However, these two studies used different CHM formulations. Two studies that tested the same CHM formulation, Bu Yang Huan Wu Tang, in combination with donepezil, reported improvement in the integrative groups, but the studies were not blind and the durations were only 8-12 weeks. Overall, methodological weaknesses limited the strength of the evidence. The herbal formulae included ingredients that have received considerable research attention for their effects on memory and cognition.

Abstract
OBJECTIVES The Montreal Cognitive Assessement (MoCA) is a brief and standardized cognitive screening tool that has been used with several clinical populations. The aim of this study was to screen the early cognitive status of patients following mild traumatic brain injury (mTBI) with the MoCA. METHODS The MoCA was administered within the first 2 weeks post-injury to 42 patients with uncomplicated mTBI, 92 patients with complicated mTBI and 50 healthy controls. RESULTS Patients with complicated mTBI had a significantly lower performance (more impairments) on the total score of the MoCA than both the group with uncomplicated mTBI and the control group. Also, the group with uncomplicated mTBI had a significantly lower performance than controls. Moreover, age, education and TBI severity had a significant effect on the MoCA total score where younger, more educated and patients with less severe (higher GCS score) mTBI performed significantly better. CONCLUSIONS The MoCA may be clinically useful to acutely screen cognition following mTBI.

Abstract
BACKGROUND Acquired brain injury (ABI) is damage to the brain that occurs after birth caused either by a traumatic or by a nontraumatic injury. The rehabilitation process following ABI should be performed by a multi-professional team, working in an interdisciplinary way, with the aim of organizing a comprehensive and holistic approach to persons with every severity of ABI. This Evidence Based Position Paper represents the official position of the European Union through the UEMS Physical and Rehabilitation Medicine (PRM) Section and designates the professional role of PRM physicians for people with ABI. The aim was to formulate recommendations on the PRM physician's professional practice for persons with ABI in order to promote their functioning and enhance quality of life. METHODS This paper has been developed according to the methodology defined by the Professional Practice Committee of the UEMS-PRM Section: a systematic literature search has been performed in PubMed and Core Clinical Journals. On the basis of the selected papers, recommendations have been made as a result of five Delphi rounds. RESULTS The literature review as well as thirty-one recommendations are presented. CONCLUSIONS The expert consensus is that structured, comprehensive and holistic rehabilitation program delivered by the multi-professional team, working in an interdisciplinary way, with the leadership and coordination of the PRM physician, is likely to be effective, especially for those with severe disability after brain injury.
