title: [An Autopsy Case of Globular Glial Tauopathy Presenting with Amyotrophic Lateral Sclerosis with Dementia].
abstract: We report an autopsy case of globular glial tauopathy (GGT) presenting clinically with amyotrophic lateral sclerosis (ALS) with dementia. A 79-year-old female developed weakness in the right upper limb, which progressed gradually. She developed apathy and speech disorder at 80 years of age. On neurological examination, she showed signs of upper and lower motor neuron disorder and dementia, but no extrapyramidal signs. The clinical diagnosis was ALS with dementia. The autopsy revealed left predominant marked atrophy of the frontal lobe due to severe neuronal loss and Gliosis. Immunohistochemistry using anti-4-repeat tau antibody revealed numerous globular glial inclusions. Severe neurodegeneration in the primary motor cortex and corticospinal tract was observed. There were distinctive tau-positive inclusions in both Betz and anterior horn cells. TDP-43-positive inclusions in motor neurons were not detected. Sequence analysis of the tau gene revealed no mutations in exons 1-5, 7, 9-13, or the adjacent intronic sequences. GGT can cause a clinical phenotype of ALS with dementia.
