Summary

This study investigated patterns of brain activity at rest in the neurodegenerative disease progressive supranuclear palsy (PSP).

The study found that participants with PSP spend more time than individuals without the disease in certain brain states, meaning their brain activity was less flexible and less efficient than normal. The time spent in these brain states was more apparent in participants who were more severely affected.

The changes in the brain’s activity did not only involve regions of the brain that are most affected by PSP, meaning that effect of the tau protein pathology of PSP has consequences across the whole brain, even where it may appear normal on a scan or have no tau pathology.
