ID 297 – Changes in finger tapping-related desynchronization during motor stroke recovery
Complex mechanisms underlying stroke recovery and modulations of associated brain activities are still far to be well elucidated. Here we investigated the potential effects of motor stroke recovery on finger tapping-related (FTR) brain dynamics by using high-power EEG with 128 channels and 2048Hz sampling rate. A follow-up study was carried out on six patients with ischemic stroke. Patients were instructed to perform finger tapping with their right or left index finger at a pace determined by a visual cue.

ID 290 – Differences in sleep microstate curves among healthy sleepers and patients after stroke
Sleep deprivation, whether from disorder or lifestyle, poses a significant risk in daytime performance. Ischemic stroke resulting in cerebral lesions is a well-known acute disorder that leaves affected patients strongly vulnerable to sleep disturbances that often lead to the above-mentioned impairments. The aim of this study is to identify objective sleep patterns being potential sources of disturbed sleep in stroke patients.

ID 127 – Small world characteristics of cortical connectivity in acute stroke
After cerebral ischemia, disruption and subsequent reorganization of functional connections occur both locally and remote to the lesion. Recently, brain complexity has been described using the graph theory, an elegant approach which depicts important properties of complex systems by quantifying topologies of network representations. We tested whether ischemic stroke may determine changes in smallworldness of cortical networks as measured by cortical sources of EEG.

The role of neurovascular ultrasound in intensive care units
The neurovascular ultrasound methods are cheap and noninvasive methods that are performed at the bedside of critically ill patients. Transcranial Doppler sonography (TCD), transcranial color Doppler sonography (TCCD) and ultrasound examination of the neck vessels can provide valuable information for timely treatment decisions. In patients with acute stroke, TCD can detect intracranial arterial steno-occlusive disease and presence of collateral flow. The recanalization rate after reperfusion treatment can be monitored with serial TCD recordings in acute ischemic stroke.

Defining abnormal slow EEG activity in acute ischaemic stroke: delta/alpha ratio as an optimal QEEG index
Ischaemic stroke (IS) produces abnormal, slow EEG activity - particularly in the delta frequency range (1-4 Hz) - and attenuation of normative, faster activity, particularly in the alpha frequency range (8-12 Hz; e.g., Jordan, 2004; Hirsch et al., 2013). A recent review (Finnigan and van Putten, 2013) emphasises that particular QEEG indices, which are sensitive to such cerebral pathophysiology following IS, can inform clinical decision-making including: (1) continuous monitoring to inform about the efficacy of acute reperfusion therapies, and; (2) outcome prognostication and clinical management decisions based on brief, pre-discharge EEG.

P99. Predictors of new cerebral microbleeds in patients with antiplatelet drug therapy
Cerebral microbleeds (CMBs) are an MRI marker of vascular damage in the brain and are associated with an increased risk for ischemic and especially hemorrhagic stroke. CMBs are known to be more prevalent in patients who take antiplatelet drug therapy, which is commonly used for secondary prevention in patients with ischemic stroke. The aim of the present study was to evaluate the usefulness of susceptibility weighted imaging (SWI) to identify patients at high risk for the development of new CMBs under antiplatelet drug therapy.

P59. Evaluation of representational deficits in neglect patients – Visual search patterns in two different bed side tests
Early diagnosis of different modalities in neglect after right hemisphere ischemic lesion and subsequent adequate therapy is crucial in regard to the clinical outcome (e.g. Buxbaum et al., 2004). Bed-side tests in the acute phase after stroke usually include only clinical examination and paper based cancellation tests (e.g. Ota search task, Bell‘s Cancellation). Additional testing such as recording of deficit in visual exploration by tracking of eye movements and standardized test for diagnosis of representational neglect have so far been only conducted in as non-bed-side tests in sub-acute or chronic stages (Isihai et al., 1989).

33. Intraoperative neurophysiological monitoring of brain perfusion during cardiac surgery in patients with asymptomatic internal carotid stenosis
Asymptomatic internal carotid (ICA) stenosis is one of documented risk factors of perioperative ischemic stroke (IS) in cardiac surgery. There is no strict consensus in benefit of prophylactic carotid endarterectomy (CEA) in asymptomatic ICA stenosis to reduce intraoperative IS. Median somatosensory evoked potentials (SEP) is reliable tool for intraoperative neurophysiological monitoring (IONM) of brain perfusion during CEA.

The P300 in middle cerebral artery strokes or hemorrhages: Outcome predictions and source localization
Stroke is the leading cause of disability and is the third leading cause of death worldwide (Murray and Lopez, 1997). According to the World Health Organisation, a total of 15 million people suffer a stroke each year. Strokes can principally be classified into two main categories, ischemic and hemorrhagic (Donnan et al., 2008). 85% of all strokes are of ischemic origin (Qureshi et al., 2001) and most commonly occur within the territory of the middle cerebral artery (MCA). The MCA supplies the lateral portion of the cerebral cortex (about 60–70% of the hemisphere).

34. Modulation of cortical activity by botulinum toxin type a in patients with post-stroke arm spasticity
Conclusion: Study of 2 age-matched groups with mild and severe weakness demonstrated different effect of BoNT-lowered spasticity on motor system engagement. Group A during movement imagery at maximum BoNT effect manifested deactivation of visual and default mode system, perhaps a change from visual to kinesthetic imagery, with cerebellum participating. Group B during movement also manifested motor pattern normalization, especially reduced activation extent.Supported by IGA MZ CR NT13575.
