Background: The risk of stroke after a transient ischemic attack (TIA) is high. Appropriately directed therapies may reduce this risk. However, sensitive means of detecting the presence of transient neuronal ischemia are lacking. Objective: To analyze the incidence of ischemic lesions detected by using diffusion-weighted MR imaging in patients suffering from transient ischemic attacks (TIA), an...

Background: Prediction of functional outcome immediately after stroke onset is difficult but become easier once it is clear that the patient is likely to survive. Several prognostic factors have been identified for outcome after stroke. Infarction size and site may have a role in motor and functional recovery after stroke. Objective: This study was carried out to evaluate the role of early CT i...

Background: Selective dorsal rhizotomy (SDR) is an established strategy for treating spastic cerebral palsy. The applied techniques and criteria of intraoperative electrophysiological monitoring (EPM) for selected transected rootlets vary between different centers; therefore its validity has been questioned. Objective: The aim of this study is to evaluate the applied techniques of EPM used duri...

Background and Purpose: Although there is some early evidence showing the value of repetitive transcranial magnetic stimulation (rTMS) in stroke rehabilitation, the therapeutic effect of high-frequency rTMS, has not been established. The aim of this study is to investigate the effect of different frequencies of rTMS on motor cortical excitability on the affected and non affected hemisphere and ...

KONOPACKI, J. Theta-like activity in the limbic cortex in vitro. NEUROSCI BIOBEHAV REV 22(2), 311–323, 1998. The generation of EEG theta rhythm in the mammalian limbic cortex is a prime example of rhythmic activity that involves central mechanisms of oscillations and synchrony. This EEG pattern has been extensively studied since 1938, when Jung and Kornmuller (28) (Eine methodik der ableitung l...

The present study was conducted on 56 patients (34 females, 22 males), presenting with aphasia due to ischemic insult in the domain of the MCA. Patients were divided into 2 groups to study the short and long-term changes of rCBF in various clinical types of aphasia. They were subjected to thorough neurological examination, assessment of aphasia using modified Chesher test and AAT, laboratory te...

Background: Swallowing dysfunction can complicate acute stroke and directly affect patient's prognosis and recovery through development of chest infection (respiratory morbidity), nutritional problems and dehydration. Objective: To study the relationship of post stroke dysphagia (assessed clinically and by pulse oximetry) with the stroke 'site and size, and with subsequent in hospital respirato...

Background: Prognostic value of blood markers in cerebral stroke is still a matter of controversies. Recently, much interest has developed in the potential use of plasma DNA as a prognostic tool in acute stroke. Objective: To assess the role of plasma DNA measured early after stroke for the correlation with clinical status of the patients at onset and for prediction of disease severity and mort...
