Metabotropic glutamate receptor 5 is associated with plasma GFAP dependent on age

Alzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Abstract INTRODUCTION We investigated the relationship between metabotropic glutamate receptor subtype 5 (mGluR5) availability and plasma biomarkers in individuals with cognitive impairment. METHODS Seventy‐one subjects were included (17 cognitively unimpaired [CU], 10 early‐onset cognitive impairment [EOCI], and 44 late‐onset cognitive impairment ...

Phenotypic diversity of frontotemporal lobar degeneration in two novel GRN variants from Colombia

Alzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Abstract INTRODUCTION Pathogenic progranulin (GRN) variants are among the main genetic causes of frontotemporal lobar degeneration (FTLD). These variants have been predominantly reported in European cohorts, but their characterization in Latin America remains scarce.

Grey matter correlates of BNT.

, 2013
Brain regions where voxel-based GM volumes are positively correlated with BNT in 344 participants aged 70-90 years, superimposed on the sagittal slices of the brain template. The slices are at 4 mm intervals between and including -48 mm and 44 mm.

Can a combination of two neuropsychological tests screen for mild neurocognitive disorder better than each test alone? A cross-sectional study

Middle East Current Psychiatry, 2020
Background Early symptoms of dementia may not be apparent and are sometimes even concealed during short office visits initiated for other complaints. The aim of the study is to find out if the combined use of VF/CDT, VF/BNT, or CDT/BNT could improve the ...

LEAD-FREE BNT PIEZOELECTRIC THIN FILMS BY SOL-GEL METHOD

, 2015
International audienceThe objective of this work is to synthesize lead-free piezoelectric thin films by the Sol-Gel method: bismuth sodium titanate (Bi0.5Na0.5TiO3 or BNT). BNT films were annealed with the rapid thermal process (RTP). The film treated at
