BACKGROUND Matrix metalloproteinase-9 (MMP-9) plays a key role for the blood-brain barrier disruption and intravenous tissue plasminogen activator (iv-tPA) therapy increases MMP-9. Edaravone, a free radical scavenger, reduces MMP-9-related blood-brain barrier disruption. We aimed to investigate whether edaravone would suppress the MMP-9 increase after(More)
BACKGROUND Lifestyle modification is associated with a substantially decreased risk of cardiovascular events. However, the role of lifestyle intervention for secondary prevention in patients with noncardioembolic ischemic stroke is inadequately defined. We assessed the hypothesis that lifestyle intervention can reduce the onset of new vascular events in(More)
The over-65 population stands at 29 million, more than 20% of the total population in Japan. This is the highest rate in the world. One-person households and older couple households will be increasing. The aim of the present study was to identify whether life and family background are significant factors for delayed presentation to hospital after stroke(More)
The concept of telestroke networks has been proposed to overcome regional disparities in stroke treatment. Such networks do not yet operate in Japan. We aimed to determine the specific needs for telestroke networks and to estimate the effects on the number of thrombolytic therapies. Five of the 47 Japanese prefectures with various population densities to(More)
A 78-year-old woman was admitted to another hospital with progressive cognitive dysfunction and right hemiparesis. Magnetic resonance imaging (MRI) of the brain revealed a high-intensity area in bilateral frontal lobes on T2-weighted imaging (T2WI) and fluid-attenuated inversion recovery (FLAIR). Brain biopsy revealed no significant findings. She was(More)
Contrast-enhanced transoral carotid ultrasonography (CETOCU) is a novel modality for imaging the distal extracranial internal carotid artery, which is not possible with conventional carotid ultrasonography. We present a representative case that demonstrates the usefulness of CETOCU.
Radiological and clinical findings of 20 cases with angiographically proven stenosis or occlusion of the vertebrobasilar system and with clinical signs and symptoms attributable to posterior circulation disorder were studied. A simplified classification of vertebrobasilar arterial disease was presented; type I refers to stenosis of the vertebrobasilar(More)
BACKGROUND We peformed a ventral intermediate nucleus (Vim) thalamotomy in a patient with Holmes' tremor and palatal tremor. The frequencies of these movement disorders were 4 Hz and 3 Hz, respectively. Vim thalamotomy stopped the Holmes' tremor but not the palatal tremor. Our observations suggest different mechanisms for these two involuntary movements. (More)
Bickerstaff brainstem encephalitis (BBE) is a rare post-infectious neurological syndrome for which an effective treatment strategy has not been established. Here, we report a case of a 71-year-old male who suffered from an upper respiratory tract infection, and 7 days later, developed numbness of the bilateral upper and lower limbs, unsteady gait and(More)
BACKGROUND To determine which patients effectively respond to ventilatory assistance (VA) and to examine the factors influencing patient response in patients who underwent cardiovascular (CV) surgery. METHODS We conducted the first walking session after surgery either with or without VA in a randomized order. The patients walked with 3cmH2O of inspiratory(More)
