| Outline of Final Research Achievements |
Cognitive impairments after stroke might interfere with return to work of the patients. The damage to the subcortical structures as well as the cortical ones could cause the cognitive deficits, such as inattention, attenuated information processing speed, and executive dysfunction . The prognosis of the deficits remains riddle. The phenomenon has been known as the cerebro-cerebellar diaschisis, which might be related to the fronto-cerebellar-thalamic loop via the brainstem. We undertook 99mTc-ECD SPECT to detect whether acute subcortical ischemia would cause extensive perfusion abnormality and to disclose the physiological significances. Additionally, using near-infrared spectroscopy with phonemic verbal fluency task (VFT), we investigated the association frontal activity of the patients and neuropsychological tests. Our results suggested that different region of the circuit would play different role for the information processing throughout the loop.
