Primary progressive aphasia (PPA) is a dementia with primarily deterioration of language abilities. The aim of the current study was to describe patterns of language decline using the Aachen Aphasia Test (AAT), with a view to differentiate the characteristics of fluent and non-fluent PPA. 20 patients were assessed in a retrospective study, 14 of them repeatedly. Patients with fluent PPA were significantly more impaired in the AAT-spontaneous speech rating scale semantic structure and in the subtest confrontation naming than patients with non-fluent PPA. In advanced stages of the disease, no intergroup differences were present any more. Mild and fast progression of language decline could be documented. A change of fluent to non-fluent PPA could be observed in two patients.
