Abstract

The patient was a 66-year-old man brought to the emergency room with impaired consciousness due to hypercarbonemia, managed on a respirator, and diagnosed with amyotrophic lateral sclerosis (ALS). MRI showed atrophy of the anterior and medial surfaces of the bilateral temporal lobes that was more severe in the right side. The patient had dysgraphia in both kana and kanji. Detailed examinations of the language function revealed impaired single-word comprehension, impaired naming, and surface dysgraphia, leading to the diagnosis of semantic variant primary progressive aphasia (svPPA). ALS patients with atrophy of the anterior temporal lobe and surface dysgraphia of kanji may have svPPA as a complication.
