Medicine - Neurology |
To report a case of the semantic variant of PPA. |
Case report |

|
Medicine - Neurology |
To analyze demographic data and classify the variants from a sample of 100 PPA cases. |
Cross-sectional study |
100 |
It was possible to classify the language impairment in 80% of the sample into one of three variants of PPA. It would be interesting to have adjustments in diagnostic recommendations to deal with cases that do not fit into any classification and to avoid cases that overlap in more than one classification. |

Medicine - Neurology |
To describe a case in which the diagnosis was divided between Alzheimer's and the logopenic variant of PPA. |
Case report |
1 |
It is possible that atypical cases of AD exhibit the logopenic variant of PPA in the early stages of the disease. |
