The primary purpose of long-term EEG monitoring is to diagnose epilepsy by identifying seizure patterns and guiding treatment.

The 10-20 system is a standard method of electrode placement for EEG monitoring, ensuring consistent and accurate recording.

Reviewing the patient's history and monitoring orders before the EEG study helps ensure that the recording is tailored to the individual's needs and specific concerns.

Concept 4 in long-term EEG monitoring focuses on understanding the different frequencies present in EEG recordings, which is crucial for accurate diagnosis and analysis.

Calibration in EEG recording is essential to verify that the equipment is working correctly and capturing data accurately.

Electroencephalogram (EEG) artifact is a result of unwanted signals and noise like movements, muscle activity, etc.

Comprehensive documentation of clinical events, stimulations, and EEG changes is crucial for accurate interpretation and analysis of the recordings.

Impedance monitoring helps reduce noise and artifacts, ensuring clear EEG recordings.

During deep sleep, delta waves, which are slow and large, dominate the brain's activity.

EEG procedures for children require specialized recording parameters and the understanding of age-related brainwave patterns.

HIPAA (Health Insurance Portability and Accountability Act) protects the privacy and security of patient information, including EEG data.

Safety protocols in EEG prioritize the well-being of both the patient and the technician during the procedure.

A standard electrode placement system used for EEG recordings, which ensures consistent and accurate positioning.

A chaotic EEG pattern characterized by high-amplitude slow waves, spikes, and sharp waves, commonly seen in infants with West Syndrome.

The initial step in troubleshooting EEG artifacts is checking the connections of electrodes to ensure they are securely attached.

Implanted devices such as pacemakers or neurostimulators can interfere with EEG signals, requiring careful monitoring and adjustment during EEG recordings.

The Health Insurance Portability and Accountability Act (HIPAA) mandates the protection of patient health information, including privacy in EEG monitoring.

Measuring the resistance between each electrode and the skin, impedance checks ensure optimal signal acquisition and efficient EEG recording.

The most prominent brain wave pattern in a relaxed adult with eyes closed, alpha waves are a regular, rhythmic pattern in the 8-12 Hz frequency.

Following infection prevention protocols when cleaning reusable electrodes is essential to ensure patient safety and prevent cross-contamination.

Long-term video-EEG monitoring allows for continuous recording and analysis of brain activity, providing crucial information for accurate diagnosis of seizure types and patterns.

Functional brain mapping identifies areas responsible for specific functions like language, movement, and sensation, helping to understand localized brain activity.

An EEG artifact often caused by loose electrode placement, resulting in a sudden, sharp spike in the recording.

Digital analysis in EEG enhances the identification of spikes and seizures by processing and highlighting specific electrical patterns in the brain.

Annotations in EEG recordings document clinical events, describe observed EEG patterns, and provide a comprehensive record for later analysis.

A type of seizure characterized by a sudden loss of muscle tone, causing the patient to collapse.

Data archiving in EEG ensures long-term accessibility of recordings for legal, medical, and research purposes, adhering to regulations and standards.

Periodic lateralized epileptiform discharges (PLEDs) are a type of electrical activity seen on an EEG that can be associated with various neurological conditions, including stroke, brain tumors, and status epilepticus.

Hyperventilation activation involves having the patient breathe rapidly and deeply, which can sometimes trigger epileptiform activity in those with epilepsy. This technique is not safe for patients with asthma, recent stroke, or cardiovascular disease, due to the potential risks.

Impedance checks measure the resistance between an electrode and the skin. A good impedance reading indicates a strong connection, minimizing noise and improving the accuracy of EEG recordings.

Electrode pop artifact is a sudden, sharp spike on the EEG caused by a sudden change in contact between the electrode and the skin. This can be caused by muscle movement, electrode displacement, or a loose connection.

EMG artifact is a high-frequency, noisy signal on the EEG that is caused by muscle activity. It can interfere with the interpretation of brain activity and needs to be minimized.

Long-term EEG monitoring involves recording brain activity for an extended period (often days or weeks), allowing for a more comprehensive view of brain activity and patterns. This documentation should include all important events, stimulations, and changes in the EEG signal.

The American Clinical Neurophysiology Society (ACNS) provides guidelines for safe and effective practices in long-term EEG monitoring.

Functional mapping involves using EEG to identify critical brain regions responsible for specific functions, such as language or motor control. This is important for pre-surgical planning to avoid damaging vital areas.

The 10-20 System is a standard electrode placement system used for EEG recordings. It is based on the distances between key anatomical landmarks on the head.

Spike-and-wave complexes are a distinctive pattern of brainwave activity often seen during generalized tonic-clonic seizures. They consist of a sharp, high-amplitude spike followed by a slower, lower-amplitude wave.

Trending analysis involves examining changes in brain activity over time based on the EEG recordings. This can help identify patterns, such as seizure frequency or progression of brain activity changes.

Reusable electrodes should be sterilized according to infection prevention guidelines to ensure patient safety and prevent the spread of infections.

A differential amplifier is a component of the EEG recording system that compares the electrical potentials between two electrodes, generating the EEG signal. This helps to reduce noise and amplify the brain's electrical activity.

Tonic seizures are characterized by sudden muscle stiffening and increased muscle tone, lasting for a short period.
