Imaging Pinpoints Markers of Anxiety Related to Parkinson's!
The insula and frontal cortex are involved in the development of anxiety in adults with Parkinson’s disease, according to imaging data from 108 individuals. Anxiety occurs in approximately 31% of Parkinson’s disease patients, but the underlying mechanisms are not well understood, wrote Nacim Betrouni, MD, of the University of Lille, France, and colleagues. Previous research has shown associations between anxiety severity and increased activity in brain areas of emotion processing, based on MRI and positron emission tomography, but electroencephalography (EEG) has not been widely used
@shiladitya The study is the first known to use EEG to explore the mechanisms of PD-related anxiety and “the reported results provide new insights, supporting findings of previous studies using other modalities, mainly rs-fMRI, and show that EEG could be a relevant technique to explore these disorders.
