A professional musician with progressive visuospatial concerns: a case study and review of musical alexia.

This case report presents the story of Mr. S, a professional orchestral musician with declining musical sight-reading ability, followed by progressive visuospatial and language deficits. Our novel musical assessment battery revealed deficits in music-reading (musical alexia) and music-writing (musical agraphia), with spared auditory perception and expression. Taken with neuropsychological testing, clinical history, and imaging, we conclude that his symptoms evolved from musical alexia to a multidomain, neurodegenerative process centered in the dominant inferior parietal lobe and temporoparietal junction. We suspect a primary TDP-opathy with comorbid preclinical Alzheimer's disease. Mr. S's case highlights musical symptoms as meaningful, early indicators of neurodegeneration.
