Primary progressive aphasia: a case report.

Abstract

Primary progressive aphasia is a progressive neurodegenerative disorder characterised by deterioration in language function while other higher centre functions are relatively preserved initially. The diagnosis is made based on clinical presentation, linguistic testing and imaging, both functional and structural. Survival is similar to other dementias and the main form of intervention is speech therapy. We describe a case of primary progressive aphasia in a Vietnamese man with corresponding changes on positron emission tomography.
