Adult onset ictal aphasia with epileptic discharges in Broca’s and Wernicke’s areas
Aphasia can sometimes present with epileptic seizures, especially in temporal lobe epilepsy affecting the dominant hemisphere. Child-onset epilepsy with aphasia is known as Landau-Kleffner Syndrome (Caraballo et al., 2014), whereas adult-onset epilepsy presenting with aphasia is quite rare, as aphasia more often presents with stroke in adult patients. Here we describe a patient with adult-onset epilepsy exhibiting ictal aphasia, and whose epileptic discharges were detected by magnetoencephalography (MEG) in the motor and sensory speech areas.

Resting-state sensorimotor rhythm (SMR) power predicts the ability to up-regulate SMR in an EEG-instrumental conditioning paradigm
During instrumental conditioning of EEG activity (EEG-IC), participants receive feedback of a specific aspect of their brain signals (Lubar et al., 1995), e.g. feedback on the power of a certain frequency band. Desired patterns of EEG activity are rewarded by visual or auditory stimuli, thus enabling participants to modulate their brain activity by means of instrumental conditioning. EEG-IC training has been used to treat patients with disorders such as epilepsy (Sterman and Egner, 2006), attention deficit hyperactivity disorder (Arns et al., 2009) and stroke (Doppelmayr et al., 2007), as well as in healthy participants (H...

1. Epileptic seizures in pediatric stroke: Data from the Italian Registry for Childhood Thrombosis
According to data from the Italian Registry for Childhood Thrombosis (R.I.T.I.), in about half cases diagnosis of pediatric stroke occurs after 24h from clinical onset (Baggio et al., SINP2013). The aim of the present study was to evaluate the frequency of seizures at stroke onset and their correlation with time to diagnosis in the pediatric stroke patients in the R.I.T.I. We selected the R.I.T.I. children with first acute arterial (AIS) or venous (CSVT) cerebral infarction occurring between January 2007 and June 2012; we studied prevalence, characteristics and recurrence of epileptic seizures, focusing on diagnostic delay.

7. Convulsive and non-convulsive seizures observed from aging mice following brian ischemia episodes
Conclusions: The early-onset seizures result from severe cerebral ischemia and brain injury. Generation of the convulsive seizures may involve deeper sub-cortical structures particularly the brainstem, and the non-convulsive EEG discharges may originate from the hippocampus. Our data may help understanding genesis of post-stroke seizures in the aging/aged population.

P 194. The EEG correlates of the TMS induced EMG silent period in humans
Application of magnetic or electrical stimulation to the motor cortex can result in a period of electromyography (EMG) silence in a tonically active peripheral muscle. This period of EMG silence is referred to as the silent period (SP). The duration of SP shows intersubject variability and reflects the integrity of the cortical and corticospinal pathways. A non-invasive technique for assessing the duration of SP is the combination of Transcranial Magnetic Stimulation (TMS) with EMG. Utilizing TMS-EMG, several studies have reported on the shortening or lengthening of SP in neuropsychiatric disorders such as schizophrenia, b...

P 172. Focal tDCS in Chronic Stroke patients: A pilot study of physiological effects using TMS and concurrent EEG
We report results of MEPs, EEG, and motor behavior. We show, for the first time, that tDCS and EEG recording can be concurrently applied in stroke patients. Bilateral M1 stimulation using small Ag/AgCl electrodes is well tolerated and can augment corticospinal excitability in the affected hemisphere. In the literature, there is only one prior studying using concurrent EEG recording during cathodal tDCS in healthy subjects and two patients with epileptic encephalopathy (Faria et al., 2012). As far as we know, no studies have applied tDCS simultaneous with EEG recording in chronic stroke patients. We report the first study i...

4. ICU EEG study
This study suggests that long-term EEG monitoring in an unselected ICU population rarely influences treatment or outcome. In a selected population with known epilepsy the benefit may be larger.
