Lesions of Left Basal Ganglia and Insula Structures Impair Executive Functions but not Emotion Recognition: A Case Report

Increasing research evidence suggests that basal ganglia are an important part of frontal- subcortical circuit which is involved not only in motor control but also in affective, cognitive and executive functions. In this article, we describe the ability of facial emotion recognition and cognitive functioning in a patient with left basal ganglia and insula damage. The patient’s ability to recognise facial emotional expressions was intact in spite of unilateral injury of the left insula and basal ganglia. He showed preserved intellectual function in general, but experienced difficulties on subsets of the executive functions: set- shifting and ability to activate or generate cognitive strategies, commonly found in patients with caudate lesions. This case contributes to evidence that striatal structures are important for executive functions.
