Language Roster Flashcards
Morphology
Morphology - morphology refers to the shape of a waveform or EEG pattern
Inion
The inion is the highest point of the occipital bone’s projection at the back of the skull, often indicated by a bump
Nasion
Nasion - point between the forehead and nose.
Montage
Montage - An EEG montage is a specific arrangement of electrode pairs, or channels, on an electroencephalographic (EEG) display. Montages are used to record and display electrical activity in the brain, and to provide information about localization and lateralization
Localization
localization is the process of identifying the location in the brain where an EEG event has occurred. Localization is a key skill in EEG interpretation, and can help determine not only where an event occurred, but also what it is.
Lateralization
lateralization is the ratio of EEG power recorded in the right hemisphere compared to the left. Brain lateralization is the idea that the brain’s two hemispheres have different functions and specializations. For example, the left hemisphere is often associated with language, while the right hemisphere is often associated with visual motor tasks.
Electrode positions, channels and # of montages
With 21 electrode positions in the 10-20 system and 16 channels, the number of possible montages is 2116
Photic Stimulation
Flashing lights test done during an EEG study
Hyperventilation
Have patient blowing in a pinwheel
Epileptiform
Anything that suggests an increased risk of seizure
Spike vs Sharp
The main difference between an EEG spike and a sharp wave is their duration: spikes are shorter, while sharp waves are longer.
Spikes and sharp waves are two types of interictal epileptiform discharges (IEDs) that are well‐recognized hallmarks of epilepsy [1].
The difference between the two is their duration: the duration of a spike is less than 70 ms whereas that of a sharp wave is between 70 and 200 ms.
Encephalopathy
A broad term for any brain disease that alters brain function or structure. Encephalopathy refers to the mental state that can happen because of several types of health problems. However, encephalitis can cause encephalopathy.
Encephalitis
encephalitis, the brain itself is swollen or inflamed
Electroencephalography (EEG)
Used to measure electrical activity in the brain
Neurologist
neurologist, a specialist medical doctor with six years of specialist training after becoming a doctor.
A neurologist is a medical doctor with specialized training in diagnosing, treating, and managing disorders of the brain and nervous system including, but not limited to, Alzheimer’s disease, amyotrophic lateral sclerosis (ALS), concussion, epilepsy, migraine, multiple sclerosis, Parkinson’s disease, and stroke.
A child or pediatric, neurologist specializes in the diagnosis and treatment of neurological disorders in children from the neonatal period through adolescence.
Some of the conditions overlap with those seen by adult neurologists, and others are unique to this younger population. Child neurologists treat many of the same common conditions found in adults such as migraine, epilepsy, stroke, and Tourette’s and are also trained in conditions related to neurogenetics and developmental problems.
Neurophysiologists
neurophysiologist is a medical doctor. They go to medical school.
Neurophysiologists are healthcare specialists who assess particular disorders of nervous system, which includes the brain, spinal cord and nerves. A neurophysiologist is a neurologist who has specialized knowledge specifically on the function of your nervous system. They perform tests and interpret the results to do so.
A neurophysiologist often doesn’t recommend treatment for neurological conditions, but a neurologist does.
There are two main types of neurophysiologists: surgical neurophysiologists and clinical neurophysiologists. They each have specific roles and responsibilities.
Neurodiagnostic Technologist/Technician
Neurodiagnostic technologists perform many tests that diagnose problems with the brain and nervous system, as well as sleep disorders. They use state-of-the-art digital equipment to record electrical patterns throughout the brain and nervous system, which results in valuable data that the doctor needs to diagnose and treat the patient. The data gathered from these tests can help diagnose conditions like epilepsy, seizure disorders, strokes, and degenerative brain disease, among others.
Scope of practice
Collaborating with doctors to treat patients who range in age from newborns to the elderly, neurodiagnostic technologists perform many tests that help diagnose brain and nervous system disorders.
Tests and procedures they perform include:
Electroencephalograms (EEGs) that are used to assess brain activity
Magnetoencephalography which detects and records magnetic fields in the brain
Intraoperative neuromonitoring to track brain and nerve function while in surgery
Polysomnograms that are used to diagnose sleep disorders
In addition to the many advanced tests and procedures they perform, neurodiagnostic technologists are also responsible for patient safety and maintaining equipment.
Work environment
Neurodiagnostic technologists typically work in hospitals, outpatient clinics, doctors’ offices, research facilities, sleep labs, and epilepsy monitoring units. This role comes in close contact with patients and spends many hours on their feet performing tests. The tests they perform can last a few hours to continuous daily monitoring. Work schedules often vary to accommodate patients’ schedules, which may include working nights and weekends.
After completing a two-year program, you are eligible to take a professional certification exam with the Nerve Conduction Association (AAET), American Board of Electrodiagnostic Medicine (ABEM), ABRET Neurodiagnostic Credentialing and Accreditation, or Board of Registered Polysomnographic Technologists (BRPT).
