Article Synopsis
  • The Medio-Dorsal Nuclei (MDN) in the thalamus is linked to verbal memory, and new research on a 77-year-old woman shows that acute confabulations occurred after an infarct in the right MDN following a previous silent infarct in the left.
  • MRI and Diffusion Tensor Imaging (DTI) were used to analyze the patient's thalamic lesions and white matter alterations, revealing lower Fractional Anisotropy (FA) and higher Mean Diffusivity (MD) in damaged areas connected to the Anterior Cingulate Cortex (ACC).
  • The study suggests that the bilateral MDN's projections to the ACC play a significant role in the development of confabulations, contributing to the

Background: Studying default mode network activity or connectivity in different parkinsonisms, with or without visual hallucinations, could highlight its roles in clinical phenotypes' expression.
