Texto completoWe describe 6 original studies, conducted on INSIGHT-PreAD and ADNI cohorts, that address different aspects of the association between patients' level of awareness of cognitive decline (ACD) and their risk of Alzheimer’s disease (AD). We used both classical statistical methods and machine learning. We show that a subtle decline is already present in preclinical AD. Patients may notice these early changes when neither the informant nor cognitive tests do. However, the informant and tests very quickly become more reliable sources of information than the patient him/herself: during the progression from the preclinical to the prodromal stage, ACD begins to decline. In prodromal AD, the patient is mildly anosognosic, until he/she usually reaches clear anosognosia in AD dementia. The clinician should consider the patient's complaint but also compare it to other, more reliable sources of information. This may also help in a better subject selection for studies targeting pre-dementia AD

Texto completoAdult neurogenesis occurring in the dentate gyrus and the olfactory bulb (OB) could be involve in cognitive processes. Moreover, precocious olfactory alterations and changes in neuromodulatory systems are constantly described in Alzheimer disease (AD). We hypothesized that bulbar neurogenesis, in relation with modifications in neuromodulation, could be involved in the development of olfactory signs of AD (Study 1). In a rodent model of the disease, the Tg2576 mice, we showed an early deficit of olfactory short term memory (OSTM) associated with a strong decrease in newborn neurons survival in the OB and a marked degeneration of the Locus Coeruleus (LC). Then, we tested the implication of the bulbar noradrenalin (NA) in the OSTM (Study 2). For that purpose, we beforehand injected the animals with the specific-noradrenergic neurotoxin DSP4 and then, lesioned and control animals were tested in a habituation-discrimination task after bulbar re-injection of saline or NA solutions. We showed that local NA is strongly involved in the modulation of habituation performances and essential to the short term memory of odorants. Finally, we assessed the influence of normal aging on bulbar neurogenesis and olfactory learning. These preliminary results showed that old mice were not able anymore to associate a food-reward with a specific odor. This deficit was associated with an almost suppression of bulbar neurogenesis and with signs of LC degeneration (Study 3). These data suggest that adult neurogenesis and noradrenergic system could be involved in some alterations linked to aging according to different mechanisms during AD or normal aging

Texto completoThe flavaglines are natural compounds, extracted from plants, which possess unique anticancer properties, display potent neuroprotective effects and may protect cardiomyocytes from cardiotoxicity induce by anthracyclines. The objective of this work was the synthesis of analogues and the study of the relation structure-activity (RSA). The variations on five different positions gave us important insight on the nature of substituent for activity. In general, the RSA on the anticancer properties, neuro- and cardioprotection were globally the same, with subtle differences. Importantly, the introduction of substituents at C-2 was deleterious on multidrug resistance cancer cell lines; and the replacement of the hydroxyl group at C-1 by an aminoformyl with the opposite configuration enhances the cytotoxicity. This work has led to an analogue that reduces tumors growth in an allograft model at non-toxic doses. Two tools to identify the biological target of flavaglines were synthesized. The first is a flavagline derivative conjugated to a dimethylaminocoumarin that allowed visualizing the accumulation of flavagline in the reticulum endoplasmic. The second is an affinity ligand for pull-down experiment and which permit to isolate the target of flavaglines. Finally, this work demonstrated that flavaglines have a real therapeutic effect for the treatment of cancer and their iatrogen effects

Texto completoThe growing proportion of people with Alzheimer's disease living at home poses problems about their safety and accompaniment. Cognitive inpairment from dementia involves memory and judgement difficulties which have repercussions on their daily life and expose them to situations of risk. The caregiver's concern is to preserve the safety of his relative, supervising, identifying and anticipating the difficulties in order to avoid risks situations. This implicit responsability, qualified as "vigilance", is an integral part of the caregivers tasks. The first aim of this study was to describe the prevalence of safety problems at home in a sample of patients with demencia seen (n=103) in a memory consultation clinic. Results show that all of the people with dementia were exposed to risks at home. The most common risks reported concerned fires, food and medication. The use of the Safety Assessment Scale is useful in the context of consultation to determine the risks at home and to focus the interview with the caregivers torwards preventing accidents and improving quality of life in the home settings. The second empirical goal of this study is to mesure, qualitatively and quantitatively, the level of vigilance of caregivers of people with dementia. Results show subgroups of caregivers with a very high level of vigilance, feeling they must now be available for their relative 24H/24. The reasons often include some patient's safety and risky behaviours, including wandering. The third aim is to explore factors associated with caregivers vigilance. The level of vigilance is associated with patient features (dependance in activities of daily living, home risks) and with characteristics of the caregiver (burden, psychological disorders). Propositions are offered in order to improve safety at home for people with dementia, and to support caregivers identified as psychologically vulnerable
