Background:
The relationship between cognitive performance and regional thalamic atrophy in multiple sclerosis (MS) has been investigated in recent studies.
Objective And Methods:
To further assess this relationship, 118 relapsing-remitting MS patients and 52 healthy controls underwent a neuropsychological assessment and a 3T-MRI (3-Tesla magnetic resonance imaging). Cognitive performances were correlated with thalamic shape changes by using Vertex Analysis.
Results:
Information processing speed performance correlated with atrophy of frontal/motor-connected thalamic sub-regions. Inhibitory control performance correlated with atrophy of all thalamic sub-regions. Global cognitive status correlated with atrophy of frontal/temporal-connected sub-regions.
Conclusions:
These findings support the hypothesis that, within the thalamus, the damage of the anterior regions is most relevant for cognitive dysfunction.
