Abstract

Primary Progressive Aphasia (PPA) is a rare neurodegenerative disease that is rarely observed with the relative preservation of mental functions such as memory, visuospatial functions, personal characteristics but that causes degeneration of speech function. Even though cognitive and behavioral functions are preserved during the starting stages, psychiatric symptoms may develop with the advancement of the disease. The objective of this study was to present a primary progressive aphasia case followed due to conversion disorder and depression for about 30 years and to discuss the confounding effects of the existing psychiatric symptoms at the diagnosis stage.
