Slow processing of information is a cognitive deficit that occurs in MS’ers.
Three structures in the brain called the basal ganglia, thalamus and neocortex are have a key role in information-processing. The basal ganglia and thalamus are groups of neurons that are found deep with in the brain and are typically referred to as the deep gray matter. The neocortex refers to the layer of cells on the surface of the brain.
This study shows that damage and shrinking in size of the basal ganglia and thalamus on MRI in MS’ers is associated with slow information processing.
