Right parietal infarction with concomitant mutism.
Abstract
Right brain damage results in a variety of cognitive and behavioural dysfunctions. Mutism however, has been described only with left or bihemispheric lesions involving the parietal lobe. We report an elderly man who had left faciobrachial monoparesis and concomitant mutism. His auditory-verbal comprehension was intact. MRI revealed a right parietal infarct involving the cortical and subcortical regions. Recovery from mutism during the course of treatment was abrupt and complete with no residual dysarthria. A possibility of diaschisis or impaired modulation of left hemispheric function due to right cerebral infarct, presenting as conversion reaction, is proposed for this rare association.
