Genetics in Degenerative Dementia: Current Status and Applicability

The aims of this systematic review are: (1) to underline the need to consider a genetic etiology of AD, FTD, and LBD; (2) to provide clinicians with information necessary to effectively translate genetic diagnosis into clinical practice; and (3) to highlight gaps and uncertainties in the field which will need to be addressed by future research.
p. 199-205 

Diagnostic Criteria for Vascular Cognitive Disorders: A VASCOG Statement
 Cognitive disorders of vascular etiology are a heterogeneous group of disorders with diverse pathologies and clinical manifestations, discussed broadly under the rubric of vascular cognitive disorders (VCD). The continuum of vascular cognitive impairment is recognized by the categories of Mild Vascular Cognitive Disorder, and Vascular Dementia or Major Vascular Cognitive Disorder. Diagnostic thresholds are defined. Clinical and neuroimaging criteria are proposed for establishing vascular etiology. Subtypes of VCD are described, and the frequent cooccurrence of Alzheimer disease pathology emphasized.
p. 206-218 

Association Between Neuropathology and Brain Volume in The Framingham Heart Study
The aim of this study was to correlate antemortem brain magnetic resonance imaging (MRI) volumes with postmortem brain pathology (both Alzheimer-related and cerebrovascular) in a community-derived cohort from the Framingham Heart Study. This study showed that volumetric MRI measures correlated with postmortem Alzheimer-related and cerebrovascular neuropathology in this community-derived cohort, confirming that these MRI measures are important antemortem surrogates for these dementia-related pathologies.
p. 219-225 

Distinctive RNA Expression Profiles in Blood Associated With Alzheimer Disease After Accounting for White Matter Hyperintensities
Background:
Defining the RNA transcriptome in Alzheimer Disease (AD) will help understand the disease mechanisms and provide biomarkers. Though the AD blood transcriptome has been studied, effects of white matter hyperintensities (WMH) were not considered. This study investigated the AD blood transcriptome and accounted for WMH.
p. 226-233 

Alzheimer Disease Cerebrospinal Fluid Biomarkers Predict Cognitive Decline In Healthy Elderly Over 2 Years
The aim of this study is to check the ability of cerebrospinal fluid biomarkers of Alzheimer disease (CSF-BMK-AD) to make a discrimination checklist within a healthy group, according to their cognitive development at 2 years of obtaining the sample.
p. 234-238 

Progressive Changes in Hippocampal Resting-state Connectivity Across Cognitive Impairment: A Cross-sectional Study From Normal to Alzheimer Disease
We investigate the changes in functional connectivity of the left and right hippocampus by comparing the resting-state low-frequency fluctuations in the blood oxygen level-dependent signal from these regions with relation to Alzheimer disease (AD) progression.
p. 239-246 

Practice Effects and Amyloid Deposition: Preliminary Data on a Method for Enriching Samples in Clinical Trials
Clinical trials in Alzheimer disease are moving toward prevention studies in prodromal individuals with amyloid burden. However, methods are needed to identify individuals expected to be amyloid positive for these studies to be feasible and cost-effective. The current study sought to determine whether short-term practice effects on cognitive tests can identify those with notable uptake on amyloid imaging.
p. 247-252

Social Relationships and Risk of Incident Mild Cognitive Impairment in US Alzheimer’s Disease Centers
Social relationships are hypothesized to prevent or slow cognitive decline. We sought to evaluate associations between social relationships and mild cognitive impairment (MCI).
p. 253-260 

Personality Changes in Dementia: Are They Disease Specific and Universal?
Previous studies about personality changes in dementia suggest that they may be due to the disruption of the biological basis of personality traits, and hence, that they are disease specific and universal. However, evidence about its specificity is still limited and scarce regarding culturally diverse populations. Accordingly, our aim was to compare personality changes in Argentinean patients with Alzheimer disease, behavioral variant of frontotemporal dementia, and primary progressive aphasia.
p. 261-268 

Community Engagement in Diverse Populations for Alzheimer Disease Prevention Trials
The recruitment of asymptomatic volunteers has been identified as a critical factor that is delaying the development and validation of preventive therapies for Alzheimer disease (AD). Typical recruitment strategies involve the use of convenience samples or soliciting participation of older adults with a family history of AD from clinics and outreach efforts. However, high-risk groups, such as ethnic/racial minorities, are traditionally less likely to be recruited for AD prevention studies, thus limiting the ability to generalize findings for a significant proportion of the aging population. A community-engagement approach was used to create a registry of 2311 research-ready, healthy adult volunteers who reflect the ethnically diverse local community. Furthermore, the registry’s actual commitment to research was examined, through demonstrated participation rates in a clinical study.
p. 269-274 

Cognitive Behavioral Group Intervention for Alzheimer Caregivers
Long-term caregiving of patients with Alzheimer disease (AD) frequently induces a relevant distress enhanced by inadequate coping strategies. This study aimed to explore the impact of cognitive and behavioral therapy (CBT) group intervention on AD patients’ caregivers. In particular, reduction in caregivers’ global care needs and in anxiety and depression has been investigated.
p. 275-282 

Altered Levels of Amyloid Precursor Protein Intracellular Domain-interacting Proteins in Alzheimer Disease
The amyloid precursor protein intracellular domain (AICD) is an intrinsically unstructured molecule with functional promiscuity that plays an important role in determining the fate of the neurons during its degeneration. Its association with Alzheimer disease (AD) recently played a key role in propelling scientists to choose AICD as a major molecule of interest. Although several studies have been conducted elucidating AICD’s participation in inducing neurodegenerative outcomes in AD condition, much remains to be deciphered regarding the linkage of AICD with cellular pathways in the AD scenario.
p. 283-290 

Brief Reports p. 291-298
  • Can Mirtazapine Counteract the Weight Loss Associated With Alzheimer Disease? A Retrospective Open-label Study
  • Rapidly Progressive Dementia as Presenting Feature in Inflammatory Bowel Disease
  • Comparative Analysis of the Alzheimer Questionnaire (AQ) With the CDR Sum of Boxes, MoCA, and MMSE
