Diagnosis To diagnose transient global amnesia, your health care provider must first rule out more-serious conditions. This can include stroke, seizure or head injury, for example. These conditions can cause the same type of memory loss. Physical exam This begins with a neurological exam, checking reflexes, muscle tone, muscle strength, sensory function, gait, posture, coordination and balance. The doctor may also ask questions to test thinking, judgment and memory. Brain and imaging tests The next step is testing to look for abnormalities in the brain's electrical activity and blood flow. Your health care provider might order one or a combination of these tests: • Computerized tomography (CT). Using special X-ray equipment, your doctor obtains images from many different angles and joins them together to show cross-sectional images of the brain and skull. CT scans can reveal abnormalities in brain structure, including narrowed, overstretched or broken blood vessels and past strokes. • Magnetic resonance imaging (MRI). This technique uses a magnetic field and radio waves to create detailed, cross-sectional images of the brain. The MRI machine can combine these slices to produce 3D images that may be viewed from many different angles. An MRI may not be needed if you had a CT scan at the time of the episode, and the CT didn't show any problems in the brain. • Electroencephalogram (EEG). An EEG records the brain's electrical activity via electrodes attached to the scalp. Peopl...

The range of frequencies one observes are between 1 and 30Hz and amplitudes will vary between 20 and 100 μV. The observed frequencies are subdivided in various groups, these are alpha (8–13Hz), beta (13–30Hz), delta (0.5–4Hz) and theta (4–7Hz). Alpha waves are observed when a person is in a state of relaxed wakefulness and are mostly prominent over parietal and occipital sites. During intense mental activity beta waves are more prominent in frontal areas as well as other regions. If a relaxed person is told to open their eyes one observes alpha activity decreasing and an increase in beta activity. Theta and delta waves are not seen in wa...

What is an EEG? An EEG is a test that detects abnormalities in your brain waves, or in the electrical activity of your brain. During the procedure, electrodes consisting of small metal discs with thin wires are pasted onto your scalp. The electrodes detect tiny electrical charges that result from the activity of your brain cells. The charges are amplified and appear as a graph on a computer screen, or as a recording that may be printed out on paper. Your healthcare provider then interprets the reading. During an EEG, your healthcare provider typically evaluates about 100 pages, or computer screens, of activity. He or she pays special attention to the basic waveform, but also examines brief bursts of energy and responses to stimuli, such as flashing lights. Evoked potential studies are related procedures that also may be done. These studies measure electrical activity in your brain in response to stimulation of sight, sound, or touch. Why might I need an EEG? The EEG is used to evaluate several types of brain disorders. When epilepsy is present, seizure activity will appear as rapid spiking waves on the EEG. People with lesions of their brain, which can result from tumors or stroke, may have unusually slow EEG waves, depending on the size and the location of the lesion. The test can also be used to diagnose other disorders that influence brain activity, such as Alzheimer's disease, certain psychoses, and a sleep disorder called narcolepsy. The EEG may also be used to determ...

An EMU evaluation plays a crucial role in a patient’s diagnosis and management with seizures and epilepsy. It is a specialized inpatient unit designed to evaluate, diagnose, and treat seizures, using state-of-the-art continuous video-electroencephalogram (EEG) monitoring technology. Patients may come to the UNC EMU for diagnosis of typical spell or seizure, localization of seizure, or anti-epileptic medication adjustment. The EMU care team consists of several Board-certified epileptologists, an epilepsy nurse practitioner, neurology- and epilepsy-trained nurses, Board-certified or eligible EEG technologists, epilepsy fellows, neurology residents and attending neurologists. Annually, we perform more than 1,200 long-term video-EEG monitoring, known as LTM or vEEG, including over 500 epilepsy monitoring unit admissions, 2,000 routine and ambulatory EEGs, 10-15 Phase II intracranial monitoring cases for epilepsy surgery and 15-20 epilepsy surgeries. Out of 500 EMU admissions, over 100 phase I epilepsy pre-surgical evaluations are performed with or without usage of ictal SPECT (single photon emission computed tomography). History The UNC EMU first opened in 1984 with four dedicated private adult beds and two dedicated pediatric beds. In 1988, UNC EMU joined NAEC as a member and performed the first Ictal Single Photon Emission Computed Tomography (SPECT). In the 1990s, the UNC Epilepsy Center started offering an epilepsy surgery treatment in addition to traditional medical thera...

Overview What’s an EEG? An EEG (electroencephalogram) measures and records your brain’s electrical signals. During an EEG, a technician places small metal disks (electrodes) on your scalp. The electrodes attach to a machine that gives your healthcare provider information about your brain’s activity. Brain activity can help your provider diagnose and monitor conditions that affect your brain. Why is an EEG performed? Most commonly, healthcare providers use an EEG to check for seizure activity related to Healthcare providers may use an EEG during brain surgery or to test the brain activity of someone in a EEGs can also check the status of brain-related conditions such as: • • • Infections, including • EEGs help diagnose the causes of symptoms such as: • Confusion. • Fainting ( • • Seizures. Who performs an EEG? A specially trained EEG technician performs the procedure. You may have an EEG in an outpatient laboratory or inpatient per your healthcare provider’s order. Some EEG tests record your brain’s activity while you go about your usual activities with an ambulatory device. What are the different types of EEG tests? There are several types of EEG tests: • Routine EEG: Routine EEG scans take 23 minutes. Your EEG technologist may ask you to breathe differently or look at flashing lights during the procedure. • Prolonged EEG: A prolonged EEG test usually takes one hour and 15 minutes, but some types can last several days. A prolonged EEG gives your healthcare provider more in...
