Abnormalities on acute magnetic resonance imaging predict outcome in minor stroke and transient ischaemic attack patients. We hypothesised that noncontrast computed tomography and computed tomography angiography findings in minor stroke and transient ischaemic attack patients would also predict functional outcome. ⋯ The presence of an acute stroke on noncontrast computed tomography or an intracranial or extracranial occlusion or stenosis was associated with an increased risk of functional impairment. Multi-modal computed tomography could be used to identify high-risk transient ischaemic attack or minor stroke patients.

To determine the predictors of efficacy, including magnetic resonance imaging information, for low-dose intravenous alteplase therapy for stroke patients. ⋯ Intravenous alteplase therapy at a dose of 0.6 mg/kg resulted in a relatively good overall outcome when compared with outcomes reported by western studies using an alteplase dose of 0.9 mg/kg. However, patients with occlusion at the internal carotid artery did not respond to this low-dose alteplase therapy.

The aim of our study is to evaluate the frequency of aphasia and to describe the characteristics of aphasics among a large sample of acute stroke patients in Italy. ⋯ This is the first study considering the frequency of aphasia in a wide population of hospitalised acute stroke patients. The presence of aphasia is more common in patients with severe stroke and contributes to residual disability. Our findings should be considered for setting early specific rehabilitation programmes.
