This paper is taken from a presentation one of us (EN) had hoped to give at the 2010 ASET Annual Conference. In it EN provides evidence that in true Alzheimer dementia (AD), memory loss is the initially dominating problem due to deterioration of the circulation in the hippocampus, which has a vulnerable blood supply to begin with. Brain pathology is likely to be secondary. Could this situation be prevented, or even reversed, with simple techniques like "head-down therapy"? What was planned to be an oral presentation by EN could not materialize because of his illness. Thanks to Janet Ghigo's invaluable assistance, our efforts have resulted in this joint presentation. The paper is presented in the conversational style Dr. Niedermeyer would have used in his oral presentation. This style reminds AJET readers of both Dr. Niedermeyer's unquenchable curiosity and his infectious enthusiasm about all research.
The study of the electroencephalogram (EEG) and other clinical neurophysiology (CNP) measurement tools has evolved over the last 70 years. In this evolutionary process, Ellen Grass and many professional technologists along the way have been instrumental in the translation of new developments in CNP technology to clinical utility. Technological developments in long-term EEG/video intensive care unit (ICU) monitoring, intraoperative monitoring, high frequency oscillation (HFO) recordings, automated signal analysis tools, seizure prediction devices, and the study of implanted intracranial recording and stimulation devices will improve our understanding of how the nervous system works. Improved understanding and translation of this evolving technology for improved patient care and outcomes remains the ultimate goal of such endeavors. Professional organizations such as the American Board of Registration of Electroencephalographic and Evoked Potential Technologists (ABRET) and the American Society of Electroneurodiagnostic Technologists (ASET) must continue to serve the CNP community and society to guide the application of this technology with an emphasis on providing information, guidelines on its use, and setting standards of professionalism. Any prior prediction of the demise of CNP technology has been greatly exaggerated. Quite the opposite has occurred, considering that the humble origins of vacuum tube powered Grass EEG machines will eventually yield to intracranial implanted microchip based recording and stimulation devices; the future appears bright for our profession.
Electrodes are an essential element of electroencephalography. Complications related to the use of recording electrodes are known to occur but not much is known about the mechanism, risk factors, and incidence of such complications. In this study, we wanted to identify the incidence and potential risk factors for electrode related skin injuries. We found that such injuries occur in 11.4% of children.
