CONCLUSION: Despite mostly insufficient reimbursement, a large proportion of the responding hospitals offer a specialized service, which largely adheres to guideline-based diagnostic procedures. The concepts of at-risk and prodromal stages of dementia seem to be largely established. PMID: 30641612 [PubMed - as supplied by publisher]

AbstractPurposeWe investigated the regional distribution of18F-THK5351 uptake in gray (GM) and white matter (WM) in patients with behavioral-variant frontotemporal dementia (bvFTD) and compared it with that in patients with Alzheimer ’s disease (AD) or semantic dementia (SD).Methods18F-THK-5351 positron emission tomography (PET),18F-florbetaben PET, magnetic resonance imaging, and neuropsychological testing were performed in 103 subjects including 30, 24, 9, and 8 patients with mild cognitive impairment, AD, bvFTD, and SD, respectively, and 32 normal subjects. Standardized uptake value ratios (SUVRs) of18F-THK-5351 P...

ConclusionsThis investigation demonstrates that early phase florbetapir uptake shows a reduction of frontal lobe perfusion in bvFTD, similar to metabolic findings with FDG. Thus, dynamic florbetapir scans can serve as a dual-phase biomarker in dementia patients to distinguish FTD from AD and cognitively normal elderly, removing the need for a separate FDG-PET scan in challenging dementia cases.

ConclusionsThe present findings show a good level of reproducibility and generalizability of a model for detecting the hypometabolic pattern in AD and confirm the accuracy of FDG-PET in Alzheimer disease.

ConclusionsWe observed focal changes of density/availability of nicotinic receptors in IGE, namely an increase in the ACC. These data suggest that the modulation of α4β2 nicotinic receptors plays a role not only in ADNFLE, but also in other genetic epileptic syndromes such as IGE and could serve as a biomarker of epilepsy syndromes with a genetic background.

CONCLUSIONS:: At this point, it is impossible to recommend any of the tools evaluated given the low number and quality of the studies. Other analyses and studies need to be conducted to develop, adapt, or further validate observational pain instruments for the end-of-life population, regardless of the disease.

In this report, we detected a 5.8-Mb deletion encompassing the chromosome 1q42.12q42.2 region in a 4-year-old boy with hypoplastic corpus callosum, epilepsy, developmental delay, microcephaly, cata ract, cleft palate, and skeletal changes. The deletion was de novo. Genotype-phenotype correlations suggest that the major features of 1q42.12q42.2 microdeletion were attributed to the genes with a high probability of loss-of-function intolerance score in this deletion, namelyLBR, ENAH, ACBD3, LIN9, ITPKB, CDC42BPA, ARF1, TAF5L, GALNT2, SPRTN, andEGLN1along with GNPAT.Mol Syndromol

DISCUSSION: Optimized tau PET classifiers may diagnose AD with high accuracy, but both tau PET and structural brain MRI capture partly unique information relevant for the clinical deterioration in AD. PMID: 30639421 [PubMed - as supplied by publisher]
