[Purpose] This study investigated the primary factors behind changes in depressive symptoms among stroke patients after 8 weeks of rehabilitation (physical, occupational, and cognitive therapy). [Methods] This study was conducted using a literature review, and electronic medical records from January, 2008 to December, 2009. Data were collected for 120 subjects with chronic stroke. [Results] Car...

BACKGROUND AND PURPOSE We aimed to determine if ischemia involving Broca area predicts Broca aphasia more reliably in acute or chronic stroke. METHODS We included consecutive right-hand-dominant patients with left hemisphere ischemic stroke (<48 hours from onset for acute stroke or >6 months after stroke for chronic stroke). MRI scans were analyzed for ischemic lesions or hypoperfusion in Bro...

Lesion-symptom mapping studies are based upon the assumption that behavioral impairments are directly related to structural brain damage. Given what is known about the relationship between perfusion deficits and impairment in acute stroke, attributing specific behavioral impairments to localized brain damage leaves much room for speculation, as impairments could also reflect abnormal neurovascu...

BACKGROUND AND PURPOSE Helicobacter pylori and Chlamydia pneumoniae have been associated epidemiologically and pathogenetically with coronary atherosclerosis. However, population-based data on chronic infection and stroke are lacking. Therefore, we investigated the association of both bacterial pathogens and ischemic stroke subtypes in a population-based case-control study. METHODS Patients w...

BACKGROUND Several studies have reported that chronic rhinosinusitis (CRS) increases the risk of stroke. The aim of this study is to elucidate the putative association between CRS and stroke (ischemic or hemorrhagic) using large population-based national health insurance data. METHODS Using the national cohort study from the Korean Health Insurance Review and Assessment Service, CRS patients ...

BACKGROUND AND PURPOSE Adenosine 5'-monophosphate-activated protein kinase (AMPK) is an important sensor of energy balance. Stroke-induced AMPK activation is deleterious because both pharmacological inhibition and genetic deletion of AMPK are neuroprotective. Metformin is a known AMPK activator but reduces stroke incidence in clinical populations. We investigated the effect of acute and chronic...

There is increasing recognition of the involvement of the immune signaling molecule, tumor necrosis factor (TNF), in the pathophysiology of stroke and chronic brain dysfunction. TNF plays an important role both in modulating synaptic function and in the pathogenesis of neuropathic pain. Etanercept is a recombinant therapeutic that neutralizes pathologic levels of TNF. Brain imaging has demonstr...

background and purpose: cancer and cerebrovascular accidents (cva) are two most common causes of mortality and morbidity in the elderly. patients with brain tumor can be highly affected by postsurgical stroke. cva may be the first manifestation in these patients . therefore, we aimed to assess the epidemiological factors affecting cva after brain surgery. methods: in this cross-sectional study ...

BACKGROUND Sickle cell diseases (SCDs) are chronic inflammatory processes on capillary level. We tried to understand some possible correlations between stroke and severity of SCDs. METHODS All patients with SCDs were taken into the study. RESULTS The study included 343 patients (174 males and 169 females). There were 30 cases (8.7%) with stroke. The mean ages were similar in both groups (32...

INTRODUCTION Stroke in young adults has seldom been studied in a necropsy series. The objective of the present clinical necropsy-based investigation was to analyze stroke and its relationship with cardiovascular and renal pathology in young adults. MATERIALS AND METHODS The protocols of 52 clinical necropsies with diagnoses of stroke in patients aged 18 - 49 years, performed between the years...
