Entropy-based algorithms have been suggested as robust estimators of electroencephalography (EEG) predictability or regularity. This study aimed to examine possible disturbances in EEG complexity as a means to elucidate the pathophysiological mechanisms in chronic stroke, before and after a brain computer interface (BCI)-motor observation intervention. Eleven chronic stroke subjects and nine un...

Alzheimer's disease (AD) is associated with an elevated risk for seizures that may be fundamentally connected to cognitive dysfunction. Supporting this link, many mouse models for AD exhibit abnormal electroencephalogram (EEG) activity in addition to the expected neuropathology and cognitive deficits. Here, we used a controllable transgenic system to investigate how network changes develop and ...

In the clinical analysis and processing for EEG, because of the difference of ages and pathology, it is possible to appear abnormal waves related with pathology. Also, the restrain of normal rhythms could be abnormal. But at present doctors estimate if certain rhythm is restrained only by using the method of eyeballing or by some simply analysis methods in clinical EEG detection, which will ine...

A key feature of normal neonatal EEG at term age is interhemispheric synchrony (IHS), which refers to the temporal co-incidence of bursting across hemispheres during trace alternant EEG activity. The assessment of IHS in both clinical and scientific work relies on visual, qualitative EEG assessment without clearly quantifiable definitions. A quantitative measure, activation synchrony index (ASI...

AIM: Epilepsy is a socially significant neurological disease spread all over the world. Valproic acid (VPA) one of most used antiepileptic drug (AED) for treatment which has some side effects on hematology field. A nowadays update to adult safety information needed. The current aim conduct cross-sectional study and describe profile adults with epilepsy treated by VPA. MATERIALS AND METHODS: Dat...

OBJECTIVE To compare the rate of abnormal brain metabolism by FDG-PET/CT to other paraclinical findings and to describe brain metabolism patterns in autoimmune encephalitis (AE). METHODS A retrospective review of clinical data and initial dedicated brain FDG-PET/CT studies for neurology inpatients with AE, per consensus criteria, treated at a single tertiary center over 123 months. Z-score ma...

This article describes a case involving the resolution of hypsarrhythmia, a generalized abnormal EEG pattern, following focal resection of a cortical tuber in a patient with tuberous sclerosis.

Ohtahara syndrome (OS) is a rare epileptic encephalopathy that is characterized by an abnormal electroencephalogram (EEG) and intractable seizures in the neonatal and early infantile period. The patient of this reported case was delivered normally at 39 weeks of gestation without any complication. One week after birth, seizures that were refractory to anticonvulsants started with repetitive clu...

OBJECTIVE To determine the sequelae of neonatal seizures in a cohort of newborns, recruited over a six month period. DESIGN Prospective hospital based study. SETTING The neonatal intensive care unit (NICU) of a tertiary care hospital. PARTICIPANTS 135 babies were recruited of whom 10 died and 25 were lost to follow up. METHODS The cases were followed up over four months. RESULTS 68% o...

Brain tumor is inherently serious and life-threatening disease. Brain tumor builds the intracranial pressure in the brain, by shifting the brain or pushing against the skull, and also damaging nerves and healthy brain tissues. This intracranial pressure affects and interferes with normal brain functionality, which results in generation of abnormal electrical activities from brain. With recent d...
