Use of Cholinesterase Inhibitors in Non-Alzheimer ’s Dementias

AbstractNon-Alzheimer ’s dementias constitute 30% of all dementias and present with major cognitive and behavioral disturbances. Cholinesterase inhibitors improve memory by increasing brain acetylcholine levels and are approved symptomatic therapies for Alzheimer’s disease (AD). They have also been investigated in ot her types of dementias with potential cholinergic dysfunction. There is compelling evidence for a profound cholinergic deficit in Lewy Body dementia (LBD) and Parkinson’s disease dementia (PDD), even to a greater extent than AD. However, this deficit is difficult to objectivize in vascular dementi a (VaD) given the increased comorbidity with AD. Furthermore, there is minimal to no evidence for cholinergic loss in frontotemporal dementia (FTD). Although cholinesterase inhibitors showed significant improvement in cognitive, behavioral, and functional measures in both LBD and PDD clinical trials , only rivastigmine is approved for PDD, due to the heterogeneity of the scales used, the duration of trials, and the limited sample sizes impacting data interpretation. Similarly, the interpretation of findings in VaD trials are limited by the lack of pre-defined inclusion criteria for ‘pure VaD’ and the wide heterogeneity of patients enrolled with respect to location and extent of cerebrovascular disease. In FTD patients, cholinesterase inhibitors were mostly associated with worsening of cognitive and behavioral symptoms. In non-AD dementias, ...

AbstractAs the worldwide population ages, the prevalence of Alzheimer's disease (AD) increases. However, the results of promising medications have been unsatisfactory. Chinese acupuncture has a long history of treating dementia, but lack of evidence from well-designed randomized controlled trials that validate its efficacy and safety, as well as its lack of clear underlying mechanisms, contribute to its limited application in clinical practice. In recent years, brain imaging technologies, such as functional magnetic resonance imaging and positron emission tomography, have been used to assess brain responses to acupuncture ...

Conclusions: Although persons with AD are often collectively considered as expensive patient group, there is large temporal and inter-individual variation in belonging to the highest decile of hospitalization and/or medication costs. It would be important to assess whether hospitalization rate could be decreased by, e.g., comprehensive outpatient care with more efficient management of comorbidities. In addition, other interventions that could decrease hospitalization rate in persons with dementia should be studied further in this context. Key messages Persons with AD had large individual fluctuation in hospital care costs ...

In this study, we aimed to develop a risk prediction model to predict fast decline in the Aβ + MCI population using multimodal biomarkers. We included 186 Aβ + MCI patients who underwent florbetapir PET, brain MRI, cerebrospinal fluid (CSF) analyses, and FDG PET at baseline. We defined conversion to dementia within 3 years (= fast decline) as the outcome. The associations of potential covariates (MCI stage, APOE4 genotype, corrected hippocampal volume (HV), FDG PET SUVR, AV45 PET SUVR, CSF Aβ, total tau (t-tau), and phosphorylated tau (p-tau)) with the outcome were tested and nomograms were constru...

Dement Geriatr Cogn Disord. 2019 Jul 18;:1-7 Authors: Ishunina TA, Bogolepova IN, Swaab DF Abstract BACKGROUND: The hypothalamic medial mamillary (MMN) and the tuberomamillary (TMN) nuclei are important hubs in memory circuits. Previous studies determining the neuronal Golgi complex size showed decreased metabolic activity of the TMN neurons in both Alzhei-mer's disease (AD) and vascular dementia (VD), and no obvious decline...

In this study, we verify the impact of CDIP parameters compliance on total brain volume variance using 86 scans of the same individual acquired on various scanners. Data included planned data collection acquired within the Consortium pour l'identification précoce de la maladie Alzheimer - Québec (CIMA-Q) and Canadian Consortium on Neurodegeneration in Aging (CCNA) studies, as well as opportunistic data collection from various protocols. For images acquired from Philips scanners, lower variance in brain volumes were observed when the stated CDIP resolution was set. For images acquired from GE scanners, lower v...
