Physical medicine and rehabilitation multidisciplinary approach in a case of posterior cortical atrophy

Abstract

Posterior cortical atrophy (PCA) is a degenerative syndrome heralded by progressive visual and spatial disorders, while the memory and execution capacities remain preserved for a long time. We report the clinical case of a female patient who received a global Physical and Rehabilitation Medicine (PRM) therapy. Our objective is to highlight the interest of a multidisciplinary approach in PCA. A female patient, LO, 60 years old, presented with visual and spatial difficulties of progressive worsening, while global cognitive efficiency was preserved, signing PCA, with a loss of autonomy in daily life. A six-month multidisciplinary approach (speech therapy, occupational therapy, and physiotherapy) centered on her visual disturbances and associated to the reinforcement of her preserved abilities, as well as a rehabilitation program, was proposed. At the end of this period, LO was again able to read, find efficient exploratory strategies, use the underground, visit museums, have leisure activities, and carry out everyday life activities, which she had ended up abandoning. The specific therapeutic management allowed reaching functional objectives. Our hypothesis is that the absence of other cognitive disorders allowed this type of rehabilitation "contract". The neurodegenerative pathologies responsible for specific instrumental disabilities without global cognitive alteration, and particularly PCA, should be able to benefit from a specific, or even multidisciplinary PMR therapy approach.
