We read with interest the study by Maeder-Ingvar et al.1 They reported 195 cases of pure monoparesis, with 42 (22%) cases involving the face, 123 (63%) cases involving an arm, and 30 (15%) cases involving a leg, from the Lausanne Stroke Registry (1979 through 2000). No correlation between stroke type and etiology was found. Echocardiography was performed in only 37% of the patients in this group; cardioembolic risk factors were found in 5% and patent foramen ovale in 4%.
