Texte intégralDespite being the second most common cognitive neurodegenerative disorder after Alzheimer’s disease (AD),dementia with Lewy bodies (DLB) is still poorly understood and represents a major scientific, clinical andpublic health problem. Magnetic resonance imaging (MRI), as a non-invasive and multimodal technique,constitutes a promising approach to improve the understanding of the underlying cerebral bases of thisdisease. In this thesis project we addressed the functional, structural and microstructural cerebral changes inpatients in the early stages of DLB compared with AD patients and healthy elderly subjects. We alsoinvestigated the links between these changes and some key-symptoms of DLB such as cognitive fluctuations.For that purpose, we combined functional connectivity analyses during a visual-perceptual paradigm andduring resting-state, morphometric analyses and quantitative multiparametric analyses. DLB patients showedsignificant functional connectivity disturbances between the salience network, the default mode network andattentional networks, that could arise from early disconnections within the salience network. Theseconnectivity changes, along with subtle grey matter volume reductions in regions of the cholinergic system,could contribute to the fluctuations characterizing DLB. In addition, we found gray matter diffusion changesin frontal regions and in the anterior cingulate cortex, associated with white matter diffusion changes inparietal and occipital regions in DLB patients, that could contribute to the functional connectivityabnormalities

Texte intégralThe aggregation of α-synuclein protein has been shown to be associated with Parkinson's disease, dementia with Lewy bodies, and multiple system atrophy, called synucleinopathies. Increasing amount of evidences suggest that synucleinopathies are prion diseases. Some aspects are missing for α-synuclein to be recognized as a prion, such as the existence of strains associated to synucleinopathies. During my thesis I set up a reliable method to amplify α-synuclein-rich deposits from patients tissues. I validated the method using all synucleinopathies tissues. This should allow the identification of α-synuclein strain related to each synucleinopathy. In addition, I also documented cleaning procedures for materials soiled with various amyloid fibers, in order to reduce the risk of contamination. Finally, I was associated to a study that shows the propagation abilities of different α-synuclein assemblies in a neuronal network mimicking human cortico-cortical connections. These results open the way to structural and functional studies of the amplified deposits

Texte intégralClinical manifestations associating motor and cognitive impairment are frequently encountered and difficult for the clinician who is required to address the problem of making the correct differential diagnosis, particularly to differentiate Parkinson's disease with dementia (PDD) from Lewy bodies dementia (LBD). In this study, we examined the neuropsychological characteristics which allow us to differentiate the two disorders. In the first study, we demonstrated that visual recognition memory is disturbed differently in the two cases. In a second study, we specified the characterisstics of the modifications encountered by using the classic "cortical" and "subcortical" dementia profiles. We also showed that, in PDD, the alteration in visual recognition memory is intermediary between Alzheimer's disease and LBD. Finally, in the last part of our study, we suggest future avenues of research needed to complete our work

Texte intégralOur first aim was to evaluate some sleep disorders which are still poorly investigated in patients with synucleinopathies (Parkinson's disease (PD), dementia with Lewy bodies (DLB), Parkinson's disease dementia (PDD) and multiple system atrophy (MSA)): insomnia, motor and behavioral phenomena emerging upon arousals from REM, and, particularly, non-REM sleep. Insomnia : Our data show that insomnia symptoms are more common in patients with PD compared to patients with other chronic medical conditions. Insomnia symptoms proved to be related to the duration of PD, but not to motor or non-motor symptoms or signs of PD (Article 1). Motor and behavioral phenomena emerging upon arousals : Patients with MP, DLB/PDD and AMS often seek medical attention for sleep-related movements and behaviors, which we proposed to label with the umbrella definition of "Parasomnia Behaviors". During these events, the patients seem to behave as if they were being enacting a dream or a fantastic setting. At video-polysomnography, these episodes prove to occur either during stable REM sleep in which physiological motor control mechanisms fail (so called REM without atonia) or during states of consciousness intermediate between sleep and wakefulness upon nocturnal arousals. In this work, we systematically studied and described for the first time the video-polysomnographic features of NREM Parasomnia Behaviors (NPBs) in a selected population of patients with MP, DLB/PDD and MSA. At quantitative analysis of the EEG frequency spectrum, we found patterns that are in favour of the hypothesis that the NPBs are likely to be underpinned by pathophysiologic mechanisms different from those underlying disorders of arousals in childhood (DOA, otherwise called NREM parasomnias). NPBs probably represent a rare, late-onset phenomenon observed in synucleinopathies (Article 3). We demonstrated that parasomnia behaviors were more common in patients with DLB/PDD than in those with PD and hypothesized that they may represent a sign of advanced disease rather than a specific hallmark of dementia (Article 2). From a pathophysiologic perspective, REM and NREM sleep parasomnias may be viewed as permissive "windows" for the exploration of sleep mental activity. In NPBs, this window would traduce a failure of the mechanisms of vigilance ("arousal"), attentional and cognitive processing during transitions from sleep to wakefulness, while in the REM sleep behavior disorder (RBD) by a failure of motor control. Overall, the findings of these studies indicate that insomnia and parasomnia behaviors could be the clinical endpoint of a functional alteration of regulators of sleep-wake activity and cognition due to the neurodegeneration associated with PD, DLB/DMP and AMS, and could reflect a more advanced stage of disease. RBD as a pathophysiological model to study the akinesia and bradykinesia : Our second aim was to set up a protocol to simultaneously record local field potentials from subthalamic nuclei neurons and video-polysomnography recordings during sleep and wakefulness in PD patients with RBD undergoing surgery for implantation of intracerebral electrodes for deep brain stimulation. This study is based on the previous observation that, during RBD, patients show, while asleep, movements and behaviors which are closer to normal movements in healthy subjects than to the movements of as PD. Three patients have been recruited and participated in this study so far (Rêves Park NST study)

Texte intégralThe question of how acetylcholine (ACh) and dopamine (DA) could be involved together in the pathophysiology of some neurodegenerative disorders is essential, particularly in dementia with Lewy bodies (DLB). The present study aims at assessing an in vivo molecular imaging method of both ACh and DA brain systems using single photon emission computed tomography. In the first part of the present study, a method based on pharmacokinetic analysis making it possible to quantify ACh neurons in vivo, using [123I]-IBVM, a specific radioligand of vesicular acetylcholine transporter, was developed and validated in healthy subjects and Alzheimer’s disease patients. Then, we showed the ability of our method to demonstrate a differential alteration of ACh pathways in Progressive Supranuclear Palsy and Multiple System Atrophy patients. In the last part of this study, we imaged for the first time both ACh and DA systems in DLB patients, using not only [123I]-IBVM, but also [123I]-FP-CIT, a specific radioligand of dopamine transporter. Concomitantly, a behavioral exploration of hallucinations, fluctuating cognition and disturbances of circadian rhythms was achieved in these patients, as well as a neuropsychological examination. This study is currently in progress. The first results show consistent links between imaging and clinical data

Texte intégralIdiopathic rapid-eye-movement sleep behaviour (iRBD) disorder can be a premotor feature of Parkinson’s disease (PD) or dementia with Lewy bodies (DLB). Depressive and anxiety symptoms are frequent nonmotor features in PD or DLB. We assessed the frequency and severity of depressive and anxiety symptoms in patients with iRBD compared to healthy control subjects. Fifty-five iRBD patients and 63 age and sexmatched healthy subjects were studied. Participants completed the Beck Depression Inventory – Second Edition (BDI-II) and Beck Anxiety Inventory (BAI). We assessed the depressive and anxiety symptoms and compared the proportion of participants with clinically significant depressive or anxiety symptoms. We also used the BDI for Primary Care (BDI-PC) to minimize confounding factors that could overestimate depressive symptoms. iRBD patients scored higher than controls on the BDI-II (9.63 ± 6.61 vs. 4.32 ± 4.58; P < 0.001)), BDI-PC (2.20 ± 2.29 vs. 0.98 ± 1.53; P = 0.001) and BAI (8.37 ± 7.30 vs. 3.92 ± 5.26; P < 0.001). Compared to controls, we found a higher proportion of patients with iRBD with either clinically significant depressive (4/63 or 6% vs. 12/55 or 22% P = 0.03) or anxiety symptoms (9/50 or 18% vs. 21/43 or 49%; P = 0.003). The proportion of iRBD patients with clinically significant depressive symptoms remains unchanged using the BDI-PC (11/55 or 20%). Depressive and anxiety symptoms are frequent features in iRBD. Routine examination of patients with iRBD disorder should include an assessment of depressive and anxiety symptoms in order to prevent or treat them.
