Meet Cesar, who was diagnosed and currently in treatment for a rare disease involving an accumulation of immature neuro histiocytes, which has created small tumors in his brain causing diffuse white matter damage. His decline in visuospatial integration and reasoning abilities are highly integrative cognitive processes that rely heavily on white matter integrity. We have been providing Cesar with cognitive rehabilitation through educational therapy, to build new connections and alternate pathways to learning. He is having great success, but needs more therapies, including Occupational therapy.
