Left Prefrontal Repetitive Transcranial Magnetic Stimulation in a Logopenic Variant of Primary Progressive Aphasia: A Case Report.

Background/aims: High frequency repetitive transcranial magnetic stimulation (hf-rTMS) improves language skills in Alzheimer's disease (AD). We report the use of hf-rTMS in a patient with logopenic primary progressive aphasia (LPPA) due to AD.

Method: hf-rTMS was applied to the left dorsolateral prefrontal cortex of a LPPA patient.

Initial neuropsychological profile of a series of 20 patients with logopenic variant of primary progressive aphasia.

Background: Logopenic variant of primary progressive aphasia (LPPA) is classically considered as an isolated language disorder, but verbal short-term memory deficit induces difficulties in neuropsychological tests that are not intended to evaluate language.

Objective: The aim of this study is to describe the initial symptoms and neuropsychological profiles of LPPA.

Methods: A retrospective study was conducted with a series of 20 consecutive patients diagnosed with LPPA.

Logopenic syndrome in posterior cortical atrophy.

Few language disorders have been reported in posterior cortical atrophy (PCA). Furthermore, no study has focused on screening for them and described these language deficits. The goal of this work was to describe linguistic examination of PCA patients and the impact of language disorders on neuropsychological performances compared to patients with other neurodegenerative syndromes and control groups.
