Continuous four hours EEG (electroencephalogram) recordings and its power spectrum analysis using fast fourier transform (FFT) in urethane anesthetized male Charles Foster rats were performed in two groups: open brain injury and p-CPA (para-Chlorophenylalanine) pretreated before brain injury, respectively, and compared with the EEG power spectrum of control rats. The EEG power spectrum analysis...

Multimodality monitoring of cerebral physiology encompasses the application of different monitoring techniques and integration of several measured physiologic and biochemical variables into assessment of brain metabolism, structure, perfusion, and oxygenation status. Novel monitoring techniques include transcranial Doppler ultrasonography, neuroimaging, intracranial pressure, cerebral perfusion...

Earlier diagnosis of cerebral vasospasm and delayed cerebral ischemia (DCI) and treatment has the potential to decrease post-bleed morbidity after subarachnoid hemorrhage (SAH). Previous studies have shown that electroencephalogram (EEG) can detect blood flow changes associated with DCI sooner than other modalities potentially leading to earlier diagnosis. However, continual monitoring with raw...

OBJECTIVE To evaluate the value of continuous electroencephalography in early prognostication in patients treated with hypothermia after cardiac arrest. DESIGN Prospective cohort study. SETTING Medical intensive care unit. PATIENTS Sixty patients admitted to the intensive care unit for therapeutic hypothermia after cardiac arrest. INTERVENTION None. MEASUREMENTS AND MAIN RESULTS In al...

the differentiation of vasovagal syncope and epileptic seizure is sometimes problematic, since vasovagal syncope may mimic epileptic seizures in many ways. the present report describes a patient who had been diagnosed and treated as having epilepsy with medically-refractory sei-zures for 16 years. often, unlike epileptic seizures, tonic-clonic convulsions and postictal confusion are uncommon fe...

-Electroencephalography is the simple method of recording and measuring electrical activity of brain. This brain signal is amplified and resulting in electroencephalogram (EEG). EEG is non-invasive tool used in monitoring brain activities and diagnosis of many neurological disorder. The main challenge of EEG is the small signal amplitude and its sensitivity to noise because of which it demands ...

OBJECTIVE To evaluate clinical data, electroencephalogram, etiology, classification, treatment, morbidity, and mortality in acute refractory status epilepticus. METHODS Fifteen patients, mean age of 41.3 years-old, six males, with refractory status epilepticus, were retrospectively studied. All of them were followed by serial electroencephalogram or continuous electroencephalographic monitori...

brain death is defined as the permanent, irreversible and concurrent loss of all brain and brain stem functions. brain death diagnosis is based on clinical criteria and it is not routine to use paraclinical studies. in some countries, electroencephalogram (eeg) is performed in all patients for the determination of brain death while there is some skepticism in relying on eeg as a confirmatory te...
