“…Language difficulties are of particular concern to brain tumor patients and greatly affect their overall quality of life. For example, difficulties with language functioning have been demonstrated to result in reduced involvement in daily activities including social activities, educational endeavors, occupational roles, and leisure activities, and have been shown to negatively impact patients' self-confidence and relationships with significant others ( Christoffersen and Wells, 1998 , Dalemans et al, 2008 , Darrigrand et al, 2011 , Thomas et al, 1995 ).
