Review
Autism spectrum disorder (ASD) is a neurodevelopmental disorder that affects 1 in 68 children in the United States. Even though it is a common disorder, only two medications (risperidone and aripiprazole) are approved by the U.S. Food and Drug Administration (FDA) to treat symptoms associated with ASD. However, these medications are approved to treat irritability, which is not a core symptom of ASD. A number of novel medications, which have not been approved by the FDA to treat ASD have been used off-label in some studies to treat ASD symptoms, including medications approved for Alzheimer's disease. Interestingly, some of these studies are high-quality, double-blind, placebo-controlled (DBPC) studies. This article systematically reviews studies published through April, 2014, which examined the use of Alzheimer's medications in ASD, including donepezil (seven studies, two were DBPC, five out of seven reported improvements), galantamine (four studies, two were DBPC, all reported improvements), rivastigmine (one study reporting improvements), tacrine (one study reporting improvements), and memantine (nine studies, one was DBPC, eight reported improvements). An evidence-based scale was used to rank each medication. Collectively, these studies reported improvements in expressive language and communication, receptive language, social interaction, irritability, hyperactivity, attention, eye contact, emotional lability, repetitive or self-stimulatory behaviors, motor planning, disruptive behaviors, obsessive-compulsive symptoms, lethargy, overall ASD behaviors, and increased REM sleep. Reported side effects are reviewed and include irritability, gastrointestinal problems, verbal or behavioral regression, headaches, irritability, rash, tremor, sedation, vomiting, and speech problems. Both galantamine and memantine had sufficient evidence ranking for improving both core and associated symptoms of ASD. Given the lack of medications approved to treat ASD, further studies on novel medications, including Alzheimer's disease medications, are needed.

PURPOSE
The increasing prevalence of Alzheimer's disease (AD) demands more effective drugs, which are still unclear. The aim of this study is to compare the effectiveness of six drugs, such as donepezil, rivastigmine, galantamine, memantine, huperzine-A, and tacrine, in senior AD patients and identify the most effective one to improve patients' cognitive function.
METHODS
A system of search strategies was used to identify relevant studies including randomized controlled trials and clinical controlled trials evaluating the efficacy of six drugs in patients with AD. We updated relevant studies that were published before March 2018 as full-text articles. Using Bayesian network meta-analysis (NMA), we ranked cognitive ability objectively based on Mini-Mental State Examination (MMSE). Pairwise and NMAs were sequentially performed for the efficacy of drugs compared to each drug or control group through the trials included.
RESULTS
Among the 35 trials included, no obvious heterogeneity ( =0.0%, =0.583) was revealed according to the pooled data for cognition in NMA and the mean difference (MD) of memantine (MD=1.7, 95% CI: 0.73, 2.8) showed that the memantine was significantly efficacious in the treatment group in terms of MMSE. Followed by galantamine, huperzine-A, rivastigmine, tacrine, and donepezil.
CONCLUSION
As the first NMA comparing the major drugs in market for AD, our study suggests that memantine might have a more significant benefit on cognition than other five drugs available.

BACKGROUND
Pharmacological treatments play a significant role in treating mild to moderate Alzheimer's disease (AD), but the optimal doses of various drugs used for these treatments are unknown. Our study compared the efficacy, acceptability, and safety of different doses of pharmacological treatments for mild to moderate AD.
METHODS
Randomized controlled trials (RCTs) were identified by searching the PubMed, EMBASE, and Cochrane Library databases (all RCTs published from the date of inception of the databases until September 19, 2019). Trials comparing the efficacy, acceptability, and safety of pharmacological interventions involving donepezil, galantamine, rivastigmine, memantine, huperzine A, and extract EGb761, alone or in combination, were identified. The primary outcomes were efficacy, acceptability, and safety.
RESULTS
Our meta-analysis included 37 studies involving 14,705 participants. In terms of improving cognitive function, galantamine 32 mg, galantamine 24 mg, donepezil 5 mg, and donepezil 10 mg were more effective than other interventions, with the surface under the cumulative ranking curve (SUCRA) values of 93.2, 75.5, 73.3, and 65.6%, respectively. According to the SUCRA values, EGb761 240 mg was considered to be the optimal intervention in terms of both acceptability and safety. With regard to clinical global impression, rivastigmine 12 mg had the highest probability of being ranked first (83.7%). The rivastigmine 15 cm patch (SUCRA = 93.7%) may be the best choice for daily living. However, there were no interventions that could significantly improve neuropsychiatric symptoms, compared with the placebo.
CONCLUSIONS
Different doses of the tested pharmacological interventions yielded benefits with regard to cognition, acceptability, safety, function, and clinical global impressions, but not effective behaviors.

Meta-Analysis
Clinical efficacy and safety of compound Congrong Yizhi Capsules on Alzheimer's disease in mainland China: A systematic review with trial sequential analysis and GRADE assessment.
ETHNOPHARMACOLOGICAL RELEVANCE
Alzheimer's disease (AD) is a degenerative disease of the central nervous system (CNS) with insidious onset. AD is also the most common cause of dementia. Compound Congrong Yizhi Capsules (CCYC), a traditional Chinese medicine compound developed by the team of Beijing University of Chinese Medicine, has been widely used to treat AD.
AIM OF THIS STUDY
To systematically evaluate the clinical efficacy and safety of CCYC for AD by meta-analysis, Trial Sequential Analysis (TSA) and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system.
METHODS
This study was registered at PROSPERO (CRD42022295496). Randomized controlled trials (RCTs) of CCYC as the treatment for AD published before December 1, 2021 were retrieved from 4 Chinses databases, 4 English databases and 2 clinical trials registration systems. RevMan 5.4 and STATA 17.0 was used to conduct the meta-analysis of the included studies, the quality of outcomes was rated by the GRADE system, the TSA was conducted by TSA 0.9.5.10 software.
RESULTS
Seven studies were included, and the total sample size was 746. Meta-analysis showed that 6 months of treatment with CCYC plus conventional western medicine treatments (CTs) improved MMSE scores compared with CTs alone (WMD: 4.32, 95% CI: 3.23, 5.42), and TSA confirmed that more trials in the future will not reverse the result. Among which, CCYC combined with donepezil can significantly improve MMSE scores (WMD: 3.54, 95% CI: 2.86, 4.22). CCYC combined with olanzapine also showed good effect on both MMSE (WMD: 6.49, 95% CI: 5.54, 7.44) and ADL scores (WMD: 5.23, 95% CI: 4.63, 5.83). No serious adverse events were reported. The strengths of the evidences above are MODERATE.
CONCLUSION
CCYC combined with cognition-modifying western medicine can improve cognitive function, mental behavioural symptoms, and activities of daily living in AD patients with good safety.

Vascular dementia (VD) is a common type of disease in the elderly. Numerous clinical trials have suggested that hyperbaric oxygen is an effective and safe complementary therapy for aging-related disorders. However, there is no reliable systematic evidence regarding hyperbaric oxygen therapy (HBOT) for the treatment of VD. Therefore, we performed a meta-analysis to evaluate the clinical efficacy and safety of HBOT in treating VD. We methodically retrieved the clinical studies from eight databases (PubMed, Cochrane Library, Embase, Web of Science, Sino-Med, China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP), and WanFang) from their inception to November 2018. RevMan 5.3.5 was used for quality assessment and data analysis. Stata 15.1 was employed for publication bias detection and sensitivity analysis. Twenty-five randomized clinical trials (RCTs) involving 1,954 patients met our inclusion criteria. These articles researched the HBOT + oxiracetam + conventional therapy (CT) vs. oxiracetam + CT ( = 13), HBOT + butylphthalide +CT vs. butylphthalide + CT ( = 5), HBOT + donepezil + CT vs. donepezil + CT ( = 4), HBOT + nicergoline + CT vs. nicergoline + CT ( = 2) and HBOT + CT vs. CT ( = 1). The results indicated that additional HBOT strikingly improved the Mini-Mental State Examination (MMSE) ( = 4.00; 95% = 3.28-4.73; < 0.00001), activities of daily living (ADL) ( = -5.91; 95% = -6.45, -5.36; < 0.00001) and ADL by Barthel index (BADL) ( = 13.86; 95% = 5.63-22.10; = 0.001) and increased the total efficacy rate (TEF) ( = 4.84, 95% = 3.19-7.33, < 0.00001). The adverse events rates were not statistically significant between the HBOT and CT groups ( = 0.85, 95% = 0.26-2.78, = 0.79). In view of the effectiveness and safety of HBOT, the present meta-analysis suggested that HBOT can be recommended as an effective and safe complementary therapy for the treatment of VD.

OBJECTIVE
The aim of this systematic review was to evaluate the effect of therapies for cognitive impairment on patients' perceived cognitive function in breast cancer survivors with chemotherapy-related cognitive impairment.
METHOD
A literature search of PubMed, Embase, and the Cochrane Library was conducted up to April 2019. Search terms included breast cancer, chemotherapy, and cognitive impairment.
RESULT
Six randomized controlled trials with a total of 305 patients were included in this review. A total of 6 randomized controlled trials using various treatments (Tibetan sound meditation, donepezil, memory and attention adaptation training, aerobic exercise, acupuncture, Qigong) for chemotherapy-related cognitive impairment met the eligibility criteria and were included. This review showed that meditative interventions (Tibetan sound meditation, Qigong) and cognitive therapy (memory and attention adaptation training) may partially improve some aspects of patients' perceived (self-reported) cognitive functioning, particularly patients' perceived cognitive impairment and ability.
CONCLUSION
In this systematic review, the results showed that meditative interventions (Tibetan sound meditation, Qigong) and cognitive therapy (memory and attention adaptation training) may be optional therapies. We hope to have more randomized controlled trials to support this result in the future.
