Subjective Assessment of Spatial Orientation Abilities in Alzheimer's Disease

Evaluation Subjective Des CApacités d'Orientation sPatialE Dans la mAladie D'Alzheimer

Source: ClinicalTrials.gov · Last updated 29 May 2026

Brief summary (registry, in English)

Difficulty orienting oneself and finding one's way around the environment, also known as "topographical disorientation" (TD) or "spatial disorientation" (SD), is a common and often early symptom of Alzheimer's disease (AD) that affects people's independence and well-being. Being able to identify it is therefore crucial in order to provide appropriate support. It cannot be assessed using conventional psychometric tests due to its low ecological validity. Several subjective assessment scales have been created to screen for SD "spatial disorientation" and assess its functional and psychological impact. However, none of these scales have been translated and validated in French. As a result, DS is not assessed in routine clinical practice. Among these scales, the Wayfinding Questionnaire (WQ) explores three dimensions: spatial orientation, distance estimation, and spatial anxiety. This questionnaire has undergone psychometric validation studies in its original Dutch version for a population with mild post-stroke , and norms for the general population have been published. Our team translated this questionnaire into French (i.e., "Questionnaire d'Orientation Spatiale" (QOS)) and adapted it cross-culturally to preserve the qualities of the measurement. A "Caregiver" version was also created, taking into account the anosognosia known to occur in AD. Primary Objective : Evaluate the psychometric properties of the Spatial Orientation Questionnaire (SOSQ) (i.e., the French translation and adaptation of the Wayfinding Questionnaire) in assessing spatial orientation disorders in patients with Alzheimer's disease, in both its "patient" and "caregiver" versions. Secondary objective : Evaluate the acceptability of the Spatial Orientation Questionnaire (SOC) in its "patient" and "caregiver" versions.
