Abstract
La maladie à corps de Lewy (MCL) est la deuxième cause de déclin cognitif d’origine neurodégénérative après la maladie Alzheimer. Elle se caractérise par des symptômes variés (troubles cognitifs, parkinsoniens, fluctuations, etc.) et est souvent mal diagnostiquée en l'absence de biomarqueurs spécifiques. Le syndrome de Capgras, fréquent dans la MCL, est une idée délirante des patients qui sont convaincus qu'un proche est remplacé par un sosie, pouvant entraîner des comportements violents. La gestion de ce syndrome repose sur des indices émotionnels pour reconnecter le patient à la réalité. Mieux comprendre ce syndrome pourrait améliorer les soins et ouvrir la voie à de nouvelles approches thérapeutiques.
Lewy body disease (LBD) is the second leading cause of neurodegenerative cognitive decline after Alzheimer's disease. It is characterized by a variety of symptoms (cognitive impairments, parkinsonism, fluctuations, etc.) and is often misdiagnosed due to the lack of specific biomarkers. Capgras syndrome, common in LBD, is a delusion where the patient believes a familiar person has been replaced by an imposter, which can lead to violent behavior. Managing this syndrome involves using emotional cues to reconnect the patient with reality. A deeper understanding of this syndrome could improve care and lead to new therapeutic approaches.
