Breaking bad news in neurology: assessing training, perceptions, and preparedness among residency programs in Brazil.

Objective: • Neurology trainees and program directors recognized a lack of structured breaking bad news training. • Program directors reported that many factors hinder the implementation of breaking bad news education. • Trainees felt capable of breaking bad news, but most did not have lectures, simulations, nor feedback.

Global efficiency of the motor network is decreased in Parkinson's disease in comparison with essential tremor and healthy controls.

Background: Graph theory (GT) is a mathematical field that analyses complex networks that can be applied to neuroimaging to quantify brain's functional systems in Parkinson's disease (PD) and essential tremor (ET).

Objectives: To evaluate the functional connectivity (FC) measured by the global efficiency (GE) of the motor network in PD and compare it to ET and healthy controls (HC), and correlate it to clinical parameters.

Methods: 103 subjects (54PD, 18ET, 31HC) were submitted to structural and functional MRI.
