Structural Connectivity and Cortical Thickness Alterations in Transient Global Amnesia.

Background And Purpose: Transient global amnesia (TGA) is a sudden onset of anterograde and retrograde amnesia. We aimed to assess differences in terms of cortical thickness and structural brain connectome between patients with TGA (at acute and delayed postrecovery stages) and matched controls.

Materials And Methods: We report on 18 consecutive patients with TGA who underwent 3T MR imaging, including DTI and MPRAGE sequences, at the acute (mean delay postonset: 44 hours) and delayed post-recovery (mean delay: 35 days) stages.

[Severe bouts of neuromyelitis optica: dramatic improvement after plasma exchanges].

Severe relapses are common in neuromyelitis optica (NMO). Plasma exchanges (PE) were successfully used to treat acute demyelinating relapses resistant to corticosteroids. However, little is known about PE efficiency in NMO relapses, particularly in relation with the presence or not of specific antibodies.
