1. In vitro Antioxidant and Anticholinesterase Activities of Ouratea fieldingiana (Gardner) Eng. Leaf Extract and Correlation with Its Phenolics Profile with an in silico Study in Relation to Alzheimer’s Disease
Ouratea fieldingiana is a native medicinal plant from Northeastern Brazil and many biological properties are due to the phenolic constituents. The objective of this work was performing the characterization of O. fieldingiana leaf constituents to correlate with antioxidant and anticholinesterase activities by in vitro and in silico studies and thus contribute

2. The role of the microbiota-gut-brain axis in neuropsychiatric disorders
The microbiota-gut-brain axis is a bidirectional signaling mechanism between the gastrointestinal tract and the central nervous system. The complexity of the intestinal ecosystem is extraordinary; it comprises more than 100 trillion microbial cells that inhabit the small and large intestine, and this interaction between microbiota and intestinal epithelium c

3. Expedient Microwave-Assisted Synthesis of Bis(n)-lophine Analogues as Selective Butyrylcholinesterase Inhibitors: Cytotoxicity Evaluation and Molecular Modelling
In the brain of patients with chronic Alzheimer’s disease (AD), the butyrylcholinesterase (BuChE) levels rise while the acetylcholinesterase (AChE) levels decrease. Therefore, development of new selective BuChE inhibitors is of vital importance. Here we present a series of bis(n)-lophine analogues, where two lophine derivatives are connected by a methylene

6. RELIGIOSIDADE E QUALIDADE DE VIDA DO INDIVIDUOS COM DOENÇA DE ALZHEIMER E DO CUIDADOR: RELAÇÕES COM ASPECTOS CLÍNICOS E COGNITIVOS
RESUMO São poucos os estudos da religiosidade de indivíduos com doença de Alzheimer (AD) e de cuidadores e as relações com a qualidade de vida (QV) e aspectos clinicos. Objetivo: Relacionar os dados do Duke University Religion Index e da Quality of life in Alzheimer’s disease scale de 39 idosos (AD: leve ou moderada) e do cuidador com aspectos clíni

7. Benzodioxol Group Driving Supramolecular Arrangement of Two Tri-Methoxy Chalcones onto Β-Secretase 1 Enzyme Active Site
Chalcones are compounds with wide interesting biological activities including Alzheimer’s disease. A comparative study was performed between the chalcones (E)-1-(2-aminophenyl)-3-(3,4,5-trimethoxyphenyl)prop-2-en-1-one and 1-(6-amino-1,3-benzodioxol-5-yl)-3-(3,4,5-trimethoxyphenyl)prop-2-en-1-one regarding the influence of benzodioxol group on their molecu

8. Functionalized Dienes: A New Series of Potential Agents for the Treatment of Alzheimer’s Disease
We report a series of functionalized dienes as compounds of great potential in the treatment of Alzheimer’s disease due to their antioxidant activity and ability to inhibit the enzyme acetylcholinesterase. The dienes tested showed high enzymatic inhibition capacity and accentuated antioxidant activity, which are comparable to or higher than the standards t

9. Topography of 11C-Pittsburgh compound B uptake in Alzheimer’s disease: a voxel-based investigation of cortical and white matter regions
Objective: To compare results of positron emission tomography (PET) with carbon-11-labeled Pittsburgh compound B (11C-PIB) obtained with cerebellar or global brain uptake for voxel intensity normalization, describe the cortical sites with highest tracer uptake in subjects with mild Alzheimer’s disease (AD), and explore possible group differences in 11C-PI

10. The validity and reliability of the CAMDEX-DS for assessing dementia in adults with Down syndrome in Brazil
Objective: Alzheimer’s disease occurs at a higher prevalence and an earlier age in individuals with Down syndrome (DS) than typically developing individuals. However, diagnosing dementia in individuals with intellectual disability remains a challenge due to pre-existing cognitive deficits. The aim of this study was to investigate the validity and reliabil

11. Two Novel Donepezil-Lipoic Acid Hybrids: Synthesis, Anticholinesterase and Antioxidant Activities and Theoretical Studies
Alzheimer disease (AD) is a complex disease related to multiple pathogenic mechanisms. A strategy to develop effective drugs is based on the so-called multi-target directed ligands (MTDL) by using hybrid compounds. So, in the present study, we have designed and synthesized two hybrids, containing the indanone-piperidine moiety of donepezil, a drug approved f

12. Diagnosing dementia in lower educated older persons: validation of a Brazilian Portuguese version of the Rowland Universal Dementia Assessment Scale (RUDAS)
Objective: To validate the Rowland Universal Dementia Assessment Scale for use in Brazil (RUDAS-BR). Methods: We first completed an English-Brazilian Portuguese translation and back-translation of the RUDAS. A total of 135 subjects over 60 years of age were included: 65 cognitively healthy and 70 with Alzheimer’s disease (AD) according to the DSM-IV and
