Please read about our recent 2015 paper discussing temporal lobe and frontal-subcortical contributions to verbal memory impairment in Parkinson’s Disease.
For this investigation, Dr. Tanner and his colleagues examined verbal memory in idiopathic Parkinson’s disease (PD) and the significance of the left entorhinal cortex and left entorhinal-retrosplenial region connections on memory impairment in Parkinson’s disease. The findings demonstrate that only white matter connections associated with the entorhinal cortex significantly contributed to memroy performance in the sample. There was no contribution from the subcortical gray matter structures typically associated with the Parkinson’s disease illness. The findings address the significance of white matter on cognition in Parkinson’s disease. It also addresses the source of memory difficulties in Parkinson’ s disease.
