Review
The objective of this review is to summarize the current data on the pharmacological treatments for frontotemporal dementias from randomized controlled trials. A systematic search of 4 major databases, PubMed, Medline, PsychINFO and Cochrane, found a total of 9 randomized controlled, double-blinded clinical trials. Of these, 2 trials used the selective serotonin reuptake inhibitor (SSRI), paroxetine; 1 trial used trazodone; 2 trials used stimulants (methylphenidate and dextroamphetamine); 1 trial used the acetylcholinesterase inhibitor, galantamine; 2 trials used the N-methyl-d-aspartate antagonist, memantine; and 1 trial used the neuropeptide oxytocin. The analysis of the available data indicates that SSRIs, trazodone, and the amphetamines may be effective in reducing some behavioral symptoms, but none of these medications had an impact on cognition. Available data indicate that these medications were well tolerated in all the trials.

Review
OBJECTIVE
To summarise existing systematic reviews that assess the effects of non-pharmacological, pharmacological and alternative therapies on activities of daily living (ADL) function in people with dementia.
DESIGN
Overview of systematic reviews.
METHODS
A systematic search in the Cochrane Database of Systematic Reviews, DARE, Medline, EMBASE and PsycInfo in April 2015. Systematic reviews of randomised controlled trials conducted in people with Alzheimer's disease or dementia measuring the impact on ADL function were included. Methodological quality of the systematic reviews was independently assessed by two authors using the AMSTAR tool. The quality of evidence of the primary studies for each intervention was assessed using GRADE.
RESULTS
A total of 23 systematic reviews were included in the overview. The quality of the reviews varied; however most (65%) scored 8/11 or more on the AMSTAR tool, indicating high quality. Interventions that were reported to be effective in minimising decline in ADL function were: exercise (6 studies, 289 participants, standardised mean difference (SMD) 0.68, 95% CI 0.08 to 1.27; GRADE: low), dyadic interventions (8 studies, 988 participants, SMD 0.37, 95% CI 0.05 to 0.69; GRADE: low) acetylcholinesterase inhibitors and memantine (12 studies, 4661 participants, donepezil 10 mg SMD 0.18, 95% CI 0.03 to 0.32; GRADE: moderate), selegiline (7 studies, 810 participants, SMD 0.27, 95% CI 0.13 to 0.41; GRADE: low), huperzine A (2 studies, 70 participants, SMD 1.48, 95% CI 0.95 to 2.02; GRADE: very low) and Ginkgo biloba (7 studies, 2530 participants, SMD 0.36, 95% CI 0.28 to 0.44; GRADE: very low).
CONCLUSIONS
Healthcare professionals should ensure that people with dementia are encouraged to exercise and that primary carers are trained and supported to provide safe and effective care for the person with dementia. Acetylcholinesterase inhibitors or memantine should be trialled unless contraindicated.

Annals of Internal Medicine Nov 2013Earlier identification of cognitive impairment may reduce patient and caregiver morbidity. (Review)
Review
BACKGROUND
Earlier identification of cognitive impairment may reduce patient and caregiver morbidity.
PURPOSE
To systematically review the diagnostic accuracy of brief cognitive screening instruments and the benefits and harms of pharmacologic and nonpharmacologic interventions for early cognitive impairment.
DATA SOURCES
MEDLINE, PsycINFO, and the Cochrane Central Register of Controlled Trials through December 2012; systematic reviews; clinical trial registries; and experts.
STUDY SELECTION
English-language studies of fair to good quality, primary care–feasible screening instruments, and treatments aimed at persons with mild cognitive impairment or mild to moderate dementia.
DATA EXTRACTION
Dual quality assessment and abstraction of relevant study details.
DATA SYNTHESIS
The Mini-Mental State Examination (k = 25) is the most thoroughly studied instrument but is not available for use without cost. Publicly available instruments with adequate test performance to detect dementia include the Clock Drawing Test (k = 7), Mini-Cog (k = 4), Memory Impairment Screen (k = 5), Abbreviated Mental Test (k = 4), Short Portable Mental Status Questionnaire (k = 4), Free and Cued Selective Reminding Test (k = 2), 7-Minute Screen (k = 2), and Informant Questionnaire on Cognitive Decline in the Elderly (k = 5). Medications approved by the U.S. Food and Drug Administration for Alzheimer disease (k = 58) and caregiver interventions (k = 59) show a small benefit of uncertain clinical importance for patients and their caregivers. Small benefits are also limited by common adverse effects of acetylcholinesterase inhibitors and limited availability of complex caregiver interventions. Although promising, cognitive stimulation (k = 6) and exercise (k = 10) have limited evidence to support their use in persons with mild to moderate dementia or mild cognitive impairment.
LIMITATION
Limited studies in persons with dementia other than Alzheimer disease and sparse reporting of important health outcomes.
CONCLUSION
Brief instruments to screen for cognitive impairment can adequately detect dementia, but there is no empirical evidence that screening improves decision making. Whether interventions for patients or their caregivers have a clinically significant effect in persons with earlier detected cognitive impairment is still unclear.

Meta-Analysis Review
BACKGROUND
Lidocaine, mexiletine, tocainide, and flecainide are local anesthetics which give an analgesic effect when administered orally or parenterally. Early reports described the use of intravenous lidocaine or procaine to relieve cancer and postoperative pain (Keats 1951; Gilbert 1951; De Clive-Lowe 1958; Bartlett 1961). Interest reappeared decades later when patient series and clinical trials reported that parenteral lidocaine and its oral analogs tocainide, mexiletine, and flecainide relieved neuropathic pain in some patients (Boas 1982; Lindblom 1984; Petersen 1986; Dunlop 1988; Bach 1990; Awerbuch 1990). With the recent publication of clinical trials with high quality standards, we have reviewed the use of systemic lidocaine and its oral analogs in neuropathic pain to update our knowledge, to measure their benefit and harm, and to better define their role in therapy.
OBJECTIVES
To evaluate pain relief and adverse effect rates between systemic local anesthetic-type drugs and other control interventions.
SEARCH STRATEGY
We searched MEDLINE (1966 through 15 May 2004), EMBASE (January 1980 to December 2002), Cancer Lit (through 15 December 2002), Cochrane Central Register of Controlled Trials (2nd Quarter, 2004), System for Information on Grey Literature in Europe (SIGLE), and LILACS, from January 1966 through March 2001. We also hand searched conference proceedings, textbooks, original articles and reviews.
SELECTION CRITERIA
We included trials with random allocation, that were double blinded, with a parallel or crossover design. The control intervention was a placebo or an analgesic drug for neuropathic pain from any cause.
DATA COLLECTION AND ANALYSIS
We collected efficacy and safety data from all published and unpublished trials. We calculated combined effect sizes using continuous and binary data for pain relief and adverse effects as primary and secondary outcome measurements, respectively.
MAIN RESULTS
Thirty-two controlled clinical trials met the selection criteria; two were duplicate articles. The treatment drugs were intravenous lidocaine (16 trials), mexiletine (12 trials), lidocaine plus mexiletine sequentially (one trial), and tocainide (one trial). Twenty-one trials were crossover studies, and nine were parallel. Lidocaine and mexiletine were superior to placebo [weighted mean difference (WMD) = -11; 95% CI: -15 to -7; P <0.00001], and limited data showed no difference in efficacy (WMD = -0.6; 95% CI: -7 to 6), or adverse effects versus carbamazepine, amantadine, gabapentin or morphine. In these trials, systemic local anesthetics were safe, with no deaths or life-threatening toxicities. Sensitivity analysis identified data distribution in three trials as a probable source of heterogeneity. There was no publication bias.
AUTHORS' CONCLUSIONS
Lidocaine and oral analogs were safe drugs in controlled clinical trials for neuropathic pain, were better than placebo, and were as effective as other analgesics. Future trials should enroll specific diseases and test novel lidocaine analogs with better toxicity profiles. More emphasis is necessary on outcomes measuring patient satisfaction to assess if statistically significant pain relief is clinically meaningful.

Review
OBJECTIVE
Research has implicated glutamatergic projections between the various frontal subregions in the pathogenesis of compulsivity and impulsivity. Reducing striatal glutamate release, or antagonising the action of glutamate at its receptors, may therefore represent viable treatment strategies. Several glutamatergic agents with regulatory approval for other indications are available and may be of potential benefit in the treatment of compulsivity/impulsivity in psychiatric disorders in paediatric patients.
METHOD
This review was performed according to PRISMA guidelines and evaluates available scientific literature concerning the use of glutamatergic agents in these patients, in order to determine their reported effectiveness/efficacy and tolerability/safety.
RESULTS
Out of a total of 1,426 publications, 21 trials examining six glutamatergic substances in patients with obsessive-compulsive disorder, autism spectrum disorders, and attention deficit/hyperactivity disorder were included.
CONCLUSIONS
Trial designs as well as results were heterogeneous and thus comparability was limited. Available data support the hypothesis that glutamatergic agents are of potential value in the treatment of compulsivity/impulsivity in children and adolescents. Based on the data reviewed, memantine and N-acetylcysteine suggest the best risk-benefit profile for future trials. Riluzole should primarily be further investigated in adults. Clinical research of this nature is a key element of the TACTICS Consortium project funded by the European Union (FP7).

Review
BACKGROUND
Alzheimer's dementia (AD) is the most common form of dementia in people with Down Syndrome (DS). There is an understanding that an increase in L-glutamate contributes to the pathogenesis of cerebral ischemias and AD. Memantine acts as an antagonist of N-methyl-D-aspartate (NMDA) type receptors, which is thought to reduce abnormal activation of glutamate neurotransmission. It binds with a low affinity to the NMDA receptor and so should not prevent learning and the formation of memory. Memantine can improve cognitive function and slow the decline of AD in the general population over time, and is the subject of this review. It is important to note that people with DS tend to present with AD at a much younger age than the normal population as well as having subtle differences in physiology (e.g. metabolism and heart rate) and may therefore have different requirements from the general population.
OBJECTIVES
To determine the effectiveness and safety of memantine for people with DS who develop AD.
SEARCH STRATEGY
CENTRAL, MEDLINE, EMBASE, CINAHL, PsycINFO, BIOSIS, SCI, SSCI and the NRR were searched up to October 2008. We contacted the manufacturers of memantine, as well as experts in the field, to ask about reports of unpublished or ongoing trials.
SELECTION CRITERIA
Randomised controlled trials of participants with DS and AD in which treatment with memantine was administered compared with a placebo group.
DATA COLLECTION AND ANALYSIS
No study was identified which met the inclusion criteria for this review.
MAIN RESULTS
No study was identified which met inclusion criteria for this review, however there is an on-going randomised controlled study being conducted in the UK and data are expected in 2009.
AUTHORS' CONCLUSIONS
As there are no included trials, recommendations cannot be made about memantine for AD in DS. Well-designed, adequately powered studies are required.

OBJECTIVE
The objective of this study was to conduct a systematic review and meta-analysis of randomized placebo-controlled trials of amantadine for the treatment of olanzapine-induced weight gain.
METHODS
Studies were identified using online searches of PUBMED/MEDLINE and Cochrane database (CENTRAL), along with websites recording trial information such as ClinicalTrials.gov, Controlled-trials.com, and Clinicalstudyresults.org. Study eligibility criteria included randomized, double-blind clinical trials comparing amantadine with placebo for olanzapine-induced weight gain with body weight as an outcome measure and study duration of at least 12 weeks. The methodological quality of included trials was assessed using the Jadad Scale. Separate meta-analyses were undertaken for each outcome (body weight and frequency of weight loss >7%) and treatment effects were expressed as weighted mean differences (WMD) and Mantel-Haenszel odds ratio for continuous and categorical outcomes, respectively.
RESULTS
A systematic review of literature revealed six studies that had assessed amantadine for olanzapine-induced weight gain. Of these, two studies (n = 144) met the review inclusion criteria and were included in the final analysis. Meta-analysis was performed to see the effect size of the treatment on body weight and frequency of body weight loss >7%. For body weight change, WMD was -1.85 (95% confidence interval [CI] -3.31 to -0.39) kg with amantadine as compared with placebo; the overall effect was statistically significant (p = 0.01). For frequency of body weight loss >7%, Mantel-Haenszel odds ratio for weight loss was 3.72 (95% CI 1.19-11.62), favoring amantadine as compared with placebo, and the overall effect was significant (p = 0.02).
CONCLUSIONS
Existing data is limited to two studies, which support the efficacy of amantadine for olanzapine-induced weight gain and a significant proportion of patients might lose weight with amantadine compared with placebo.

Meta-Analysis Review
BACKGROUND
Fatigue and unintentional weight loss are two of the commonest symptoms experienced by people with advanced progressive illness. Appropriate interventions may bring considerable improvements in function and quality of life to seriously ill people and their families, reducing physical, psychological and spiritual distress.
OBJECTIVES
To conduct an overview of the evidence available on the efficacy of interventions used in the management of fatigue and/or unintentional weight loss in adults with advanced progressive illness by reviewing the evidence contained within Cochrane reviews.
METHODS
We searched the Cochrane Database of Systematic Reviews (CDSR) for all systematic reviews evaluating any interventions for the management of fatigue and/or unintentional weight loss in adults with advanced progressive illness (The Cochrane Library 2010, Issue 8). We reviewed titles of interest by abstract. Where the relevance of a review remained unclear we reached a consensus regarding the relevance of the participant group and the outcome measures to the overview. Two overview authors extracted the data independently using a data extraction form. We used the measurement tool AMSTAR (Assessment of Multiple SysTemAtic Reviews) to assess the methodological quality of each systematic review.
MAIN RESULTS
We included 27 systematic reviews (302 studies with 31,833 participants) in the overview. None of the included systematic reviews reported quantitative data on the efficacy of interventions to manage fatigue or weight loss specific to people with advanced progressive illness. All of the included reviews apart from one were deemed of high methodological quality. For the remaining review we were unable to ascertain the methodological quality of the research strategy as it was described. None of the systematic reviews adequately described whether conflict of interests were present within the included studies. Management of fatigueAmyotrophic lateral sclerosis/motor neuron disease (ALS/MND) - we identified one systematic review (two studies and 52 participants); the intervention was exercise.Cancer - we identified five systematic reviews (116 studies with 17,342 participants); the pharmacological interventions were eicosapentaenoic acid (EPA) and any drug therapy for the management of cancer-related fatigue and the non pharmacological interventions were exercise, interventions by breast care nurses and psychosocial interventions.Chronic obstructive pulmonary disease (COPD) - we identified three systematic reviews (59 studies and 4048 participants); the interventions were self management education programmes, nutritional support and pulmonary rehabilitation.Cystic fibrosis - we identified one systematic review (nine studies and 833 participants); the intervention was physical training.Human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) - we identified two systematic reviews (21 studies and 748 participants); the interventions were progressive resistive exercise and aerobic exercise.Multiple sclerosis (MS) - we identified five systematic reviews (23 studies and 1502 participants); the pharmacological interventions were amantadine and carnitine. The non pharmacological interventions were diet, exercise and occupational therapy.Mixed conditions in advanced stages of illness - we identified one systematic review (five studies and 453 participants); the intervention was medically assisted hydration. Management of weight lossALS/MND - we identified one systematic review but no studies met the inclusion criteria for the systematic review; the intervention was enteral tube feeding.Cancer - we identified three systematic reviews with a fourth systematic review also containing extractable data on cancer (66 studies and 5601 participants); the pharmacological interventions were megestrol acetate and eicosapentaenoic acid (EPA) (this systematic review is also included in the cancer fatigue section above). The non pharmacological interventions were enteral tube feeding and non invasive interventions for patients with lung cancer.COPD - we identified one systematic review (59 studies and 4048 participants); the intervention was nutritional support. This systematic review is also included in the COPD fatigue section.Cystic fibrosis - we identified two systematic reviews (three studies and 131 participants); the interventions were enteral tube feeding and oral calorie supplements.HIV/AIDS - we identified four systematic reviews (42 studies and 2071 participants); the pharmacological intervention was anabolic steroids. The non pharmacological interventions were nutritional interventions, progressive resistive exercise and aerobic exercise. Both of the systematic reviews on exercise interventions were also included in the HIV/AIDS fatigue section.MS - we found no systematic reviews which considered interventions to manage unintentional weight loss for people with a clinical diagnosis of multiple sclerosis at any stage of illness.Mixed conditions in advanced stages of illness - we identified two systematic reviews (32 studies and 4826 participants); the interventions were megestrol acetate and medically assisted nutrition.
AUTHORS' CONCLUSIONS
There is a lack of robust evidence for interventions to manage fatigue and/or unintentional weight loss in the advanced stage of progressive illnesses such as advanced cancer, heart failure, lung failure, cystic fibrosis, multiple sclerosis, motor neuron disease, Parkinson's disease, dementia and AIDS. The evidence contained within this overview provides some insight into interventions which may prove of benefit within this population such as exercise, some pharmacological treatments and support for self management.Researchers could improve the methodological quality of future studies by blinding of outcome assessors. Adopting uniform reporting mechanisms for fatigue and weight loss outcome measures would also allow the opportunity for meta-analysis of small studies.Researchers could also improve the applicability of recommendations for interventions to manage fatigue and unintentional weight loss in advanced progressive illness by including subgroup analysis of this population within systematic reviews of applicable interventions.More research is required to ascertain the best interventions to manage fatigue and/or weight loss in advanced illness. There is a need for standardised reporting of these symptoms and agreement amongst researchers of the minimum duration of studies and minimum percentage change in symptom experience that proves the benefits of an intervention. There are, however, challenges in providing meaningful outcome measurements against a background of deteriorating health through disease progression. Interventions to manage these symptoms must also be mindful of the impact on quality of life and should be focused on patient-orientated rather than purely disease-orientated experiences for patients. Systematic reviews and primary intervention studies should include the impact of the interventions on standardised validated quality of life measures.

Meta-Analysis Review
Antipsychotic-related weight gain and metabolic effects are a critical outcome for patients requiring these medications. A literature search using MEDLINE, Web of Science, PsycNET, and EMBASE for randomized, open and double-blind, placebo-controlled trials of medications targeting antipsychotic-induced weight gain was performed. Primary outcome measures were change and endpoint values in body weight and body mass index (BMI). Secondary outcomes included >or=7% weight gain, all-cause discontinuation, change in waist circumference, glucose and lipid metabolism parameters, and psychiatric symptoms. Sensitivity analyses were conducted to explain heterogeneity of the results. Across 32 studies including 1482 subjects, 15 different medications were tested: amantadine, dextroamphetamine, d-fenfluramine, famotidine, fluoxetine, fluvoxamine, metformin, nizatidine, orlistat, phenylpropanolamine, reboxetine, rosiglitazone, sibutramine, topiramate, and metformin+sibutramine. Compared with placebo, metformin had the greatest weight loss (N=7, n=334, -2.94 kg (confidence interval (CI:-4.89,-0.99)), followed by d-fenfluramine (N=1, n=16, -2.60 kg (CI:-5.14,-0.06)), sibutramine (N=2, n=55, -2.56 kg (CI:-3.91,-1.22)), topiramate (N=2, n=133, -2.52 kg (CI:-4.87,-0.16)), and reboxetine (N=2, n=79, -1.90 kg (CI:-3.07,-0.72)). Weight loss remained significant with metformin initiation after weight gain had occurred, but not when started concomitantly with antipsychotics. Nausea rates were not higher with any treatment compared with placebo. In all, 5 of 15 psychopharmacologic interventions aimed at ameliorating antipsychotic-induced weight gain outperformed placebo. Results were most robust for metformin, although these were modest and heterogeneous. Only one (negative) combination treatment study was available and head-to-head studies are absent. None of the agents were able to entirely reverse weight gain because of antipsychotics. At present, no treatment has sufficient evidence to recommend broad clinical usage. Antipsychotics with no or minimal cardiometabolic liability, as well as interventions that prevent or normalize adverse antipsychotic cardiometabolic effects are needed.

Meta-Analysis Review
INTRODUCTION
Sexual dysfunction frequently occurs in patients with schizophrenia under antipsychotic therapy, and the presence of sexual side effects may affect compliance. The aim of this study was to review and describe clinical findings relating to the appropriate management of such dysfunctions.
MATERIAL AND METHODS
The research was carried out through Medline (from 1966 to March 2005), PsycInfo (from 1974 to March 2005), and Cochrane Library (from 1965 to March 2005) and included any kind of study, from case reports to randomized trials.
RESULTS
The most common sexual dysfunctions found in the literature were libido decrease, difficulties in achieving and maintaining erection, ejaculatory dysfunction, orgasmic dysfunction, and menstrual irregularities. Thirteen papers were found: eight of them were open-label studies, four were descriptions of cases, and only one was a randomized clinical trial. All of them were short-term and had small sample sizes. The agents used were: bromocriptine, cabergoline, cyproheptadine, amantadine, shakuyaku-kanzo-to, sildenafil and selegiline.
DISCUSSION
There was no evidence that those agents had proper efficacy in treating the antipsychotic-induced sexual dysfunction. An algorithm for managing sexual dysfunction induced by antipsychotics is suggested as a support for clinical decisions. Since the outcome from schizophrenia treatment is strongly related to compliance with the antipsychotics, prevention of sexual dysfunction is better than its treatment, since there is a scarcity of data available regarding the efficacy of intervention to deal with these problems.
