Computed tomography (CT) findings in 57 patients with senile dementia of Alzheimer type (SDAT), 19 patients with multi-infarct dementia and 85 controls of similar age and sex were studied. The SDAT patients differed from the controls of ventricular dilatation, frontal horn index, cella media index and the width of the third ventricle, and also in the index of cortical atrophy. Even the least se...

Stroke is one of the leading causes death and disability worldwide. However, treatment options for ischemic stroke remain limited. Matrix-metalloproteinases (MMPs) contribute to brain damage during strokes by disrupting blood-brain barrier (BBB) causing edemas. Carnosine, an endogenous dipeptide, was found us others be protective against injury. In this study, we investigated whether carnosine ...

OBJECTIVE To evaluate the factors that can influence evolution of communication after a first stroke. METHOD Thirty-seven adult patients were evaluated for speech and language within 72 hours after a single first-ever ischemic brain injury and later on. Patients who were comatose, with decompensated systemic diseases, or history of chronic alcoholism or illicit drug use were not included. Bra...

BACKGROUND AND PURPOSE Intra-arterial cell transplantation offers a novel therapeutic strategy for stroke; however, it remains unclear how the timing of cell administration affects cell distribution, brain repair processes, and functional recovery. Here, we investigate the hypothesis that the timing of cell transplantation changes the behavior of the cell graft and the host environment in a way...

myocardial infarction is a common presentation of coronary artery disease and the leading cause of death worldwide. the present study was investigated potential resistance to ischemia-reperfusion (i/r) injuries following administration of methanolic (meoh) extract of scrophularia frigida (s. frigida) in isolated rat heart. male wistar rat hearts (n= 8-10) were isolated and allowed to equilibrat...

Introduction: A vital step in the evaluation of acute and chronic stroke involves volume quantification of the infarct as determined from diffusion-weighted images (DWI) [1]. The routine assessment of infarct size is by visual review of the approximate size reported along with the location of the defect with reference to the brain anatomy. Assessment of the infarct volume is critical to managem...

Recovery of function after stroke is thought to be dependent on the reorganization of adjacent, surviving areas of the brain. Macroscopic imaging studies (functional magnetic resonance imaging, optical imaging) have shown that peri-infarct regions adopt new functional roles to compensate for damage caused by stroke. To better understand the process by which these regions reorganize, we used in ...

Cerebral infarct due to embolic stroke without recanalization was examined by cerebral blood flow (CBF) SPECT in the early acute stage, and the possibility of predicting the size it will reach in the later stages was evaluated. Twenty patients (67 +/- 13 years) were examined by CBF SPECT with 99mTc-ECD 4.5 +/- 3.1 hours after the onset of cardiogenic cerebral embolism. The ratio of the anteropo...
