International audience; Studying rare extreme forms of Alzheimer disease (AD) may prove to be a useful strategy in identifying new genes involved in monogenic determinism of AD. Amyloid precursor protein (APP), PSEN1, and PSEN2 mutations account for only 85% of autosomal dominant early-onset AD (ADEOAD) families. We hypothesised that rare copy number variants (CNVs) could be involved in ADEOAD families without mutations in known genes, as well as in rare sporadic young-onset AD cases. Using high-resolution array comparative genomic hybridisation, we assessed the presence of rare CNVs in 21 unrelated ADEOAD cases, having no alteration on known genes, and 12 sporadic AD cases, with an age of onset younger than 55 years. The analysis revealed the presence of 7 singleton CNVs (4 in ADEOAD and 3 in sporadic cases) absent in 1078 controls and 912 late-onset AD cases. Strikingly, 4 out of 7 rearrangements target genes (KLK6, SLC30A3, MEOX2, and FPR2) encoding proteins that are tightly related to amyloid-β peptide metabolism or signalling. Although these variants are individually rare and restricted to particular subgroups of patients, these findings support the causal role, in human pathology, of a set of genes coding for molecules suspected for a long time to modify Aβ metabolism or signalling, and for which animal or cellular models have already been developed.

International audience; We describe 56 novel autosomal dominant early-onset Alzheimer disease (ADEOAD) families with PSEN1, PSEN2, and AβPP mutations or duplications, raising the total of families with mutations on known genes to 111 (74 PSEN1, 8 PSEN2, 16 AβPP, and 13 AβPP duplications) in the French series. In 33 additional families (23% of the series), the genetic determinism remained uncharacterized after this screening. Cerebrospinal fluid (CSF) biomarker levels were obtained for patients of 58 families (42 with known mutations and 16 without genetic characterization). CSF biomarkers profile was consistent with an AD diagnosis in 90% of families carrying mutations on known genes. In families without mutation, CSF biomarkers were consistent with AD diagnosis in 14/16 cases. Overall, these results support further genetic heterogeneity in the determinism of ADEOAD and suggest that other major genes remain to be characterized.

International audience; Introduction. Le TOP 12 évalue la mémoire collective au travers d'une série de huit types de questions portant sur le souvenir de la vie de 12 célébrités nommément désignées. La validation de tels tests est souvent envisagée dans le seul but de prédire un critère externe au test (validation externe) ; la validation interne n'est quant à elle que très rarement étudiée. Objectifs. Montrer comment les réponses obtenues peuvent mesurer une seule grandeur hypothétique (appelée aussi construit) : la capacité de la mémoire collective. Méthodes. L'échantillon est composé de 145 sujets (91 témoins, 32 patients présentant une maladie d'Alzheimer, 21 patients ayant un trouble cognitif léger de type amnésique, 1 patient ayant une démence sémantique). Deux étapes sont nécessaires : modéliser les réponses aux items à l'aide d'un modèle de réponse à l'item à trois paramètres et tester l'unidimensionnalité des scores estimés. Résultats. Les huit modèles s'ajustent étroitement aux données. L'analyse factorielle confirmatoire ne permet pas de rejeter l'idée selon laquelle les huit types de questions mesurent bien une seule et unique grandeur hypothétique. Conclusion. La modélisation psychométrique des données observées avec le TOP 12 indique qu'elles mesurent la capacité de la mémoire collective.

Le TOP 12 examine la mémoire collective simplement et rapidement par huit types de question portant sur le souvenir de la vie de 12 célébrités nommément désignées. Objectifs. Vérifier la corrélation entre les scores moyens et le degré de sévérité de la pathologie ; déterminer un seuil permettant de conjecturer sur l'état de la personne au vu de son score au test. Méthodes. L'échantillon est composé de 145 sujets (91 témoins, 32 patients présentant une maladie d'Alzheimer, 21 patients ayant un trouble cognitif léger de type amnésique ou MCIa, 1 patient ayant une démence sémantique). Les propriétés diagnostiques du TOP 12 ont pu être mises en avant en confrontant deux méthodologies : le centilage et la courbe Receiver Operator Characteristic (ROC). Résultats. L'ordre des moyennes et l'ordre des niveaux de gravité pathologique des groupes sont corrélés. Le seuil qui optimise le compromis entre la sensibilité (Se) et la spécificité (Sp) est donné par la méthodologie de la courbe ROC (83 points ; Se = 0,83 ; Sp = 0,70). Le cinquième centile s'avère non optimal étant donné qu'il majore les omissions. Conclusion. Cette validation externe du TOP 12 montre l'intérêt de la méthodologie de la courbe ROC.

diffusion, transport ,ddc:530 - Abstract
Extraction of accurate quantitative parameters to characterize water diffusion in complex porous media like brain tissue in neuroimaging is a challenging inverse problem, that depends on medium\''s structural and geometrical factors [1,3]. If the role of membranes is generally invoked, probe collisions with the insoluble cytoskeleton network and water hydrodynamic interactions with dissolved macromolecules and cytoskeleton occur as well [2]. The latter two interactions have been shown to determine the phenomenological “anomalous diffusion” of probes in the cytoplasm [4,5,6,7,8]. Additionally, the diffusion of small solutes in cytoplasm could be slowed by the local micro-viscosity of the aqueous phase, a phenomenon generally not taken into account in simulations. We suggest that the Grey and White Matter contrast in Diffusion Decay Imaging (DDI) could be caused by differences in cytoskeleton structures, composed respectively of actin and tubulin that could act by the elimination of one possible water diffusion pathlength by the volume occupied by the network phase. This could explain why anomalous DDI signal has been shown to be independent of membrane integrity [9]. Cytoplasm is able to rapidly shift from a sol (aqueous solutions embedded with insolubles particles) to a gel state (a colloidal solutions with a structured semi-solid and an aqueous fluid phase) or to a viscous solution when the insoluble particles become soluble. Does water have the ability of being a sensor of its local “self-viscosity” ? What is the length of the water diffusion\''s path compared to cells size ? Compared to this path length, how many cellular structures should be probed by water\''s translational diffusion ? We try to respond to these questions by investigating Diffusion Decay Imaging models and their effects on the hypothese-free q-space diffusion propagator shape [3], containing all informations concerning viscosity-slowed gaussian diffusion, structural informations [3] and restricted diffusion [1].

The event-related potential N270 component is known to be an electrophysiological marker of the supramodal conflict processing. However little is know about the factors that may modulate its amplitude. In particular, among all studies that have investigated the N270, little or no control of the conflict strength and of the load in working memory have been done leaving a lack in the understanding of this component. We designed a spatial audiovisual conflict task with simultaneous target and cross-modal distractor to evaluate the N270 sensitivity to the conflict strength (i.e., visual target with auditory distractor or auditory target with visual distractor) and the load in working memory (goal task maintenance with frequent change in the target modality). In a first session, participants had to focus on one modality for the target position to be considered (left-hand or right-hand) while the distractor could be at the same side (compatible) or at opposite side (incompatible). In a second session, we used the same set of stimuli as in the first session with an additional distinct auditory signal that clued the participants to frequently switch between the auditory and the visual targets. We found that (1) reaction times and N270 amplitudes for conflicting situations were larger within the auditory target condition compared to the visual one, (2) the increase in target maintenance effort led to equivalent increase of both reaction times and N270 amplitudes within all conditions and (3) the right dorsolateral prefrontal cortex current density was higher for both conflicting and active maintenance of the target situations. These results provide new evidence that the N270 component is an electrophysiological marker of the supramodal conflict processing that is sensitive to the conflict strength and that conflict processing and active maintenance of the task goal are two functions of a common executive attention system.

- Abstract
Causative variants in APP, PSEN1 or PSEN2 account for a majority of cases of autosomal dominant early-onset Alzheimer disease (ADEOAD, onset before 65 years). Variant detection rates in other EOAD patients, that is, with family history of late-onset AD (LOAD) (and no incidence of EOAD) and sporadic cases might be much lower. We analyzed the genomes from 264 patients using whole-exome sequencing (WES) with high depth of coverage: 90 EOAD patients with family history of LOAD and no incidence of EOAD in the family and 174 patients with sporadic AD starting between 51 and 65 years. We found three PSEN1 and one PSEN2 causative, probably or possibly causative variants in four patients (1.5%). Given the absence of PSEN1, PSEN2 and APP causative variants, we investigated whether these 260 patients might be burdened with protein-modifying variants in 20 genes that were previously shown to cause other types of dementia when mutated. For this analysis, we included an additional set of 160 patients who were previously shown to be free of causative variants in PSEN1, PSEN2 and APP: 107 ADEOAD patients and 53 sporadic EOAD patients with an age of onset before 51 years. In these 420 patients, we detected no variant that might modify the function of the 20 dementia-causing genes. We conclude that EOAD patients with family history of LOAD and no incidence of EOAD in the family or patients with sporadic AD starting between 51 and 65 years have a low variant-detection rate in AD genes.

Objective: Because of its heterogeneity in clinical presentation and course, predicting autoimmune encephalitis (AIE) evolution remains challenging. Hence, our aim was to explore the correlation of several biomarkers with the clinical course of disease. Methods: Thirty‐seven cases of AIE were selected retrospectively and divided into active (N = 9), improved (N = 12) and remission (N = 16) AIE according to their disease evolution. Nine proteins were tested in both serum and cerebrospinal fluid (CSF) at diagnosis (T0) and during the follow‐up (T1), in particular activated MMP‐9 (MMP‐9A) and YKL‐40 (or chitinase 3‐like 1). Results: From diagnosis to revaluation, AIE remission was associated with decreased YKL‐40 and MMP‐9A levels in the CSF, and with decreased NfL and NfH levels in the serum. The changes in YKL‐40 concentrations in the CSF were associated with (1) still active AIE when increasing >10% (P‐value = 0.0093); (2) partial improvement or remission when the changes were between +9% and −20% (P‐value = 0.0173); and remission with a reduction > −20% (P‐value = 0.0072; overall difference between the three groups: P‐value = 0.0088). At T1, the CSF YKL‐40 levels were significantly decreased between active and improved as well as improved and remission AIE groups but with no calculable threshold because of patient heterogeneity. Conclusion: The concentration of YKL‐40, a cytokine‐like proinflammatory protein produced by glial cells, is correlated in the CSF with the clinical course of AIE. Its introduction as a biomarker may assist in following disease activity and in evaluating therapeutic response. [ABSTRACT FROM AUTHOR]

Frontotemporal dementia (FTD) refers to a disease spectrum including the behavioral variant FTD (bvFTD), primary progressive aphasia (PPA), progressive supranuclear palsy/corticobasal degeneration syndrome (PSP/CBDS), and FTD with amyotrophic lateral sclerosis (FTD-ALS). A GGGGCC expansion in C9ORF72 is a major cause of FTD and ALS. C9ORF72 was analyzed in 833 bvFTD, FTD-ALS, PPA, and PSP/CBDS probands; 202 patients from 151 families carried an expansion. C9ORF72 expansions were much more frequent in the large subgroup of patients with familial FTD-ALS (65.9%) than in those with pure FTD (12.8%); they were even more frequent than in familial pure ALS, according to estimated frequencies in the literature (23-50%). The frequency of carriers in non-familial FTD-ALS (12.7%) indicates that C9ORF72 should be analyzed even when family history is negative. Mutations were detected in 6.8% of PPA patients, and in 3.2% of patients with a clinical phenotype of PSP, thus enlarging the phenotype spectrum of C9ORF72. Onset was later in C9ORF72 (57.4 years, 95%CI: 55.9-56.1) than in MAPT patients (46.8, 95%CI: 43.0-50.6; p = 0.00001) and the same as in PGRN patients (59.6 years; 95%CI: 57.6-61.7; p = 0.4). ALS was more frequent in C9ORF72 than in MAPT and PGRN patients; onset before age 50 and parkinsonism were indicative of MAPT mutations, whereas hallucinations were indicative of PGRN mutations; prioritization of genetic testing is thus possible. Penetrance was age- and gender-dependent: by age 50, 78% of male carriers were symptomatic, but only 52% of females. This can also guide genetic testing and counseling. A flowchart for genetic testing is thus proposed. [ABSTRACT FROM AUTHOR]

We report the case of a 62-year-old asymptomatic carrier of AβPP gene duplication. He was investigated by MRI and the amyloid ligand
18 F-AV45, and compared to Alzheimer's disease patients (n = 11) and healthy controls (n = 11). The neuropsychological examination was normal. Cortical thickness and AV45 retention were comparable to Alzheimer's disease patients. AβPP duplication was diagnosed because cerebral amyloid angiopathy and Alzheimer's disease pathology were found on the neuropathological examination of his youngest brother, who died at 42 from intracerebral hemorrhage. This is the first description of a pre-symptomatic AβPP duplication carrier over 60, despite widespread cerebral amyloid angiopathy, 'Alzheimer's like' atrophy, and amyloid deposition.

- Abstract
There is an ongoing debate regarding the respective role of anterior subhippocampal structures and the hippocampus in recognition memory. Here, we report a double anatomo-functional dissociation observed in two brain-damaged patients, FRG and JMG. They both suffered from complete destruction of left MTL structures. In the right hemisphere however, FRG sustained extensive lesions to the hippocampus sparing anterior subhippocampal structures, while JMG suffered from the reversed pattern of lesion, i.e., extensive damage to anterior subhippocampal structures but preserved hippocampus. FRG was severely amnesic and failed all recall tasks involving visual material, but exhibited normal performance at a large battery of visual recognition memory tasks. JMG was not amnesic and showed the opposite pattern of performance. These results strongly support the view that right anterior subhippocampal structures are a critical relay for visual recognition memory in the human. © 2010 Wiley-Liss, Inc. [ABSTRACT FROM AUTHOR]

- Abstract
Initialement reconnu comme un syndrome de l’enfance, les données scientifiques indiquent qu’une proportion significative d’enfants atteints du trouble du déficit de l’attention avec ou sans hyperactivité (TDA/H) continue de présenter des symptômes à l’âge adulte. Le diagnostic reste clinique en dépit des caractéristiques cliniques, neuropsychologiques, biologiques, génétiques ou de neuroimagerie identifiées mais insuffisantes individuellement pour confirmer le diagnostic. Considérant que le TDA/H est basé sur un modèle neuropsychologique, nous examinerons dans un premier temps la nature des troubles cognitifs à travers les données issues des méta-analyses de l’adulte et la valeur prédictive des outils neuropsychologiques. Les résultats de ces études attestent que les fonctions d’inhibition, de flexibilité mentale, de vigilance et d’attention soutenue sont les plus sensibles à l’identification du TDAH de l’adulte. Si les valeurs prédictives positives des tests neuropsychologiques spécifiques de ces troubles sont bonnes, les valeurs prédictives négatives restent quant à elles insatisfaisantes.

- Abstract
En 1911, le Dr Alois Alzheimer a décrit plusieurs crises convulsives chez l’un des premiers cas identifiés de la pathologie neuroévolutive portant désormais son nom. Cependant le lien physiopathologique entre la maladie d’Alzheimer (MA) et l’épilepsie est resté peu exploré pendant un siècle entier, ou bien seulement considéré comme un symptôme des formes familiales extrêmement rares de la MA. Tout a changé au début des années 2000, avec plusieurs publications décrivant, d’une part, une incidence accrue des crises d’épilepsie chez les patients atteints des formes sporadiques de la MA, et d’autre part, le rôle des plaques Aβ et des enchevêtrements neurofibrillaires dans les activités paroxystiques spontanées dans des modèles génétiques précliniques de la pathologie. Ces publications ont permis d’introduire la perspective d’un dysfonctionnement de réseaux neuronaux dans cette pathologie et ont déclenché une avalanche d’études sur la caractérisation de l’épilepsie chez les patients MA ainsi que sur les mécanismes sous-jacents de cette comorbidité. Ces travaux de recherche ont mis en évidence plusieurs interrelations entre l’épilepsie et la MA, commençant par l’impact des agrégats Aβ et Tau, mais également l’implication de facteurs liés aux perturbations du sommeil, l’altération du fonctionnement du système glymphatique ou bien des altérations des réseaux neuronaux de l’hippocampe, l’aire la plus touchée par les activités paroxystiques dans cette comorbidité. Finalement, des études chez des modèles animaux de la MA suggèrent une efficacité particulière de certains traitements antiépileptiques sur les activités paroxystiques et sur des symptômes de la MA. Ceci parait d’autant plus important au vue des nombreuses études chez les patients épileptiques dévoilant la contribution potentielle de ces activités paroxystiques au dysfonctionnement mnésique caractéristique de la MA ainsi qu’à la progression de la pathologie.

L’encéphalite auto-immune (EAI) est un groupe hétérogène de maladies inflammatoires du système nerveux, susceptible d’entraîner une altération du sommeil. Même si le nombre d’études sur le sommeil dans les EAI a augmenté ces dernières années, celles-ci sont basées sur des petites cohortes et n’étudient pas ou peu la microarchitecture et l’électrogenèse du sommeil.

- Abstract
C9orf72repeat expansions are rarely associated with primary progressive aphasias (PPA). In-depth characterization of the linguistic deficits, and the underlying patterns of grey-matter atrophy in PPA associated with the C9orf72expansions (PPA-C9orf72) are currently lacking. In this study, we comprehensively analyzed a unique series of 16 patients affected by PPA-C9orf72. Eleven patients were issued from two independent French and Finnish cohorts, and five were identified by means of literature review. Voxel-based morphometry (VBM) studies were performed on three of them.

Primary familial brain calcification (PFBC) is a neurological disease characterized by calcium phosphate deposits in the basal ganglia and other brain regions and has thus far been associated with SLC20A2, PDGFB or PDGFRB mutations. We identified in multiple families with PFBC mutations in XPR1, a gene encoding a retroviral receptor with phosphate export function. These mutations alter phosphate export, implicating XPR1 and phosphate homeostasis in PFBC. [ABSTRACT FROM AUTHOR]

Accurate segmentation of thalamic nuclei, crucial for understanding their role in healthy cognition and in pathologies, is challenging to achieve on standard T1-weighted (T1w) magnetic resonance imaging (MRI) due to poor image contrast. White-matter-nulled (WMn) MRI sequences improve intrathalamic contrast but are not part of clinical protocols or extant databases. In this study, we introduce histogram-based polynomial synthesis (HIPS), a fast preprocessing transform step that synthesizes WMn-like image contrast from standard T1w MRI using a polynomial approximation for intensity transformation. HIPS was incorporated into THalamus Optimized Multi-Atlas Segmentation (THOMAS) pipeline, a method developed and optimized for WMn MRI. HIPS-THOMAS was compared to a convolutional neural network (CNN)-based segmentation method and THOMAS modified for the use of T1w images (T1w-THOMAS). The robustness and accuracy of the three methods were tested across different image contrasts (MPRAGE, SPGR, and MP2RAGE), scanner manufacturers (PHILIPS, GE, and Siemens), and field strengths (3 T and 7 T). HIPS-transformed images improved intra-thalamic contrast and thalamic boundaries, and HIPS-THOMAS yielded significantly higher mean Dice coefficients and reduced volume errors compared to both the CNN method and T1w-THOMAS. Finally, all three methods were compared using the frequently travelling human phantom MRI dataset for inter- and intra-scanner variability, with HIPS displaying the least inter-scanner variability and performing comparably with T1w-THOMAS for intra-scanner variability. In conclusion, our findings highlight the efficacy and robustness of HIPS in enhancing thalamic nuclei segmentation from standard T1w MRI. [ABSTRACT FROM AUTHOR]
