In 1948, Paul Yakovlev described an additional limbic circuit located basolateral to James Papez’s circuit (1937) and included orbitofrontal cortex, amygdala and dorsomedial nucleus of thalamus. This circuit is shown to be an important component of subcortical cognitive abilities. We aimed to demonstrate this circuit in a multiple sclerosis (MS) cohort, using diffusion tensor imaging (DTI) and evaluate its role in MS related cognitive impairment (CI). We enrolled cognitively intact (n=10) and impaired (n=36) MS patients who underwent a comprehensive cognitive assessment; the Minimal Assessment of Cognitive Function in Multiple Sclerosis (MACFIMS) and structural magnetic resonance imaging (MRI). Correlation analyses between volumetric and DTI derived values of the orbitofrontothalamic (OFT), amygdalothalamic tracts (ATT) and dorsomedial nucleus of thalamus and CI index derived from MACFIMS were computed after adjustment for age, education and lesion load. We observed a consistent trend between CI index and bilateral dorsomedial nucleus’ mean diffusivity (MD) (r=0.316; p: 0.02), left OFT FA (r:−0.302; p:0.02), MD (r=0.380; 0.006), and radial diffusivities (RD) (r=0.432; p:0.002), also with right ATT FA (r=−0.475; p:0.0006) and left ATT FA (r=−0.487; p:0.0005). After Bonferroni correction, correlations of left OFT RD, right and left ATT FA with CI were found to be significant. Our study provides in vivo DTI delineation of Yakovlev’s historical basolateral limbic circuit and establishes a role in MS related CI. These findings may potentially pave the way for future clinical studies using targeted invasive and non-invasive neurostimulation modalities for cognitive impairment in MS.
