    Abstract:
    To elucidate the precise recovery process and prognosis of language functions in aphasic patients with left putaminal hemorrhage, we investigated 48 aphasic patients classified into 4 groups according to the location and extent of hematoma. The hematoma extended to the corona radiata in all patients, extracapsular in type I (12 cases), to the anterior limb in type II (10 cases), to the posterior limb in type III (12 cases), and to both limbs in type IV (14 cases). The Standard Language Test for Aphasia was performed at 1 month, 3 months, and 6 months after the attack. The type II, III, and IV patients were divided into 2 groups, with and without ventricular rupture of the hemorrhage. At 3 and 6 months after the attack, the type I, II, and III patients showed significant improvement (P < .05) in all language modalities compared with the type IV patients. Most improvement in language modalities occurred in the first 3 months. The evaluation of patients with ventricular rupture after 6 months revealed poor recovery (P < .05) in oral commands, visual commands, confrontation naming, sentence repetition, narratives, verbal fluency, and writing in type II and III patients. In type IV patients, this evaluation showed poor recovery (P < .05) only in oral and written naming (kanji words). No significant difference in prognostic outcome was observed between the surgical treatment group and the nonsurgical treatment group. The classification of hemorrhage may be useful in predicting the outcome of aphasia with putaminal hemorrhage and in guiding clinicians in providing effective instructions to patients and their relatives.
