Circuit dysfunction is clearly recognized as a driver of neuropsychiatric disease, and some neurodegenerative diseases such as Parkinson’s disease. And at the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) 2022 Congress, researchers made an argument that the same is true in multiple sclerosis (MS). Such a lens could explain the radiological-clinical paradox between the amount of structural damage and clinical severity.

How well connectomic models of the brain could be used to the predict performance of a specific person on cognitive tests was influenced by sociodemographic characteristics of that person, such as age and education. The findings, which were published in the Aug. 25, 2022, issue of Nature, suggest that models of cognition “are not predicting unitary cognitive constructs, such as episodic memory. Rather, they are predicting composites: measures of these constructs intertwined with sociodemographic and clinical covariates,” first author Abigail Greene told BioWorld.
