Abstract

Early differential diagnosis of dementia is becoming increasingly important as new pharmacologic therapies are developed, as these treatments are not equally effective for all types of dementia. Early detection and differential diagnosis also facilitates informed family decision making and timely access to appropriate services. Information about gait characteristics is informative in the diagnostic process and may have important implications for discriminating among dementia subtypes. The aim of this review paper is to summarize existing research examining the relationships between gait and dementia, including gait classification systems and assessment tools, gait patterns characteristic of different dementias (Alzheimer's disease, vascular dementia, dementia with Lewy Bodies, and fronto-temporal dementia), and the utility of gait analysis in early-stage diagnosis. The paper concludes with implications for future research.

Résumé

Le diagnostic différentiel précoce entre les formes de démence revêt de plus en plus d'importance au fil de l'émergence de nouveaux traitements médicamenteux qui sont efficaces dans certaines formes de démence et pas dans d'autres. La détection et le diagnostic différentiel précoces ont également pour avantages de permettre à la famille de prendre des décisions éclairées et de faciliter l'accès opportun aux services appropriés. Les caractéristiques de la démarche sont l'un des éléments essentiels du diagnostic et cette information serait utile dans la distinction entre les formes de démence. Le présent exposé de synthèse fait le point sur la recherche concernant le lien entre la démarche et la démence en présentant notamment des systèmes de classification et des méthodes d'évaluation de la démarche, les caractéristiques de la démarche selon le type de démences, dont la maladie d'Alzheimer, la démence vasculaire, la démence à corps de Lewy et la démence frontotemporale, et l'utilité de l'analyse de la démarche dans le diagnostic à un stade précoce. L'exposé se termine par les perspectives de la recherche à l'avenir.
