Development of the Effectiveness of Rehabilitation Tools for Neurovisual Disorders in Patients With Posterior Cortical Atrophy (REEDUC-ACP)

March 21, 2023 updated by: Centre Hospitalier Universitaire de Nice

Development and Evaluation of the Effectiveness of Rehabilitation Tools for Neurovisual Disorders in Patients With Posterior Cortical Atrophy (PCA)

Posterior cortical atrophy (PCA) is manifested by neuro-visual disorders that alter the spatial location of objects, their manipulation and/or recognition. Its etiology is most often neurodegenerative, with a major impact on the autonomy and mood of patients and their families. Few studies have focused on non-medication management of these disorders.

The present study thus has a double objective: the development of a complete tool to work on the recognition, localization and/or manipulation of objects; and the evaluation of the effectiveness of this type of management.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Recognition of objects
Patients will do the therapy in the following order: object location, object manipulation and object recognition
Behavioral: Recognition of objects
  • Name of shapes / colors / images / objects
  • Classification of shapes / colors / images / objects
Experimental: Location of objects
Patients will do the therapy in the following order: object recognition, object location, and object manipulation
Behavioral: Location of objects
  • Search for frequent/rarse targets among distractors sharing one or more characteristics with the target
  • Hit/catch a stationary/mobile target as quickly as possible
Experimental: Manipulation of objects
Patients will do the therapy in the following order: object manipulation, object recognition and object location
Behavioral: Manipulation of objects
