The 69 pages that link to Electroencephalography, each with the reason it gives.

• Signal-to-noise ratioRelated: Brain signals are weak relative to muscular, electrical, and instrumental interference.

• Neurological examinationRelated: It measures brain activity directly, unlike examination findings inferred from observed responses.

• EpilepsyRelated: EEG can reveal epileptiform patterns and help characterize seizure activity.

• NeuroscienceRelated: EEG reveals population-level brain rhythms and is used in both research and clinical care.

• SleepRelated: It reveals the changing brain-wave patterns used to classify sleep stages.

• SeizureRelated: It can reveal electrical patterns associated with seizures.

• DeliriumRelated: Electroencephalography can reveal diffuse brain slowing or identify seizures that resemble delirium.

• ElectrodeRelated: Recording electrodes detect voltage differences generated by neural activity.

• Functional magnetic resonance imagingCompared with: EEG tracks electrical activity directly and quickly, unlike fMRI's indirect, delayed vascular signal.

• NeuroimagingRelated: It measures brain electrical activity directly, with millisecond-scale timing.

• Electroconvulsive therapyRelated: EEG monitoring helps clinicians assess seizure activity during an ECT treatment.

• NeurologyRelated: EEG helps evaluate seizures and other disturbances of brain function.

• Status epilepticusRelated: EEG can detect ongoing nonconvulsive seizures when outward signs are absent.

• PolysomnographyCompared with: Polysomnography includes EEG but adds respiratory, movement, and other channels.

• ArousalRelated: EEG patterns provide an indirect measure of changes in arousal and vigilance.

• ComaRelated: It can reveal seizures or patterns of brain activity that examination alone may miss.

• ElectrophysiologyBroader topic: It captures summed neural signals for clinical assessment and research.

• Focal SeizureRelated: EEG can reveal patterns that support focal onset, although a normal recording does not exclude it.

• EncephalitisRelated: It can detect seizures and abnormal brain activity during encephalitis.

• PropofolRelated: Brain-wave patterns can help characterize and monitor propofol-induced unconsciousness.

• Sleep architectureRelated: Its signals help distinguish sleep stages by their characteristic patterns.

• Brain–computer interfaceRelated: It is a common noninvasive way to capture signals for brain–computer interfaces.

• ElectroretinographyCompared with: Unlike EEG, ERG measures retinal responses directly, before signals travel through the optic nerve.

• Cognitive neuroscienceRelated: Its millisecond timing helps link brain signals to stages of mental processing.

• MagnetoencephalographyCompared with: EEG detects the same broad class of neural currents, but measures scalp voltage rather than magnetic fields.

• Lucid dreamingRelated: EEG helps identify sleep stages and study brain activity during lucid dreams.

• Auditory brainstem responseNarrower topic: The test uses scalp electrodes to detect tiny, time-locked neural signals.

• BrainRelated: EEG reveals patterns of brain activity, including seizures and sleep stages.

• Herpes simplex encephalitisRelated: EEG can detect seizures and support diagnosis when temporal-lobe abnormalities are present.

• Locked-in syndromeRelated: EEG can support assessment of brain function when behavioral responses are difficult to interpret.

• Rapid eye movement sleepRelated: EEG reveals REM's low-amplitude, mixed-frequency activity.

• Creutzfeldt–Jakob diseaseRelated: Periodic EEG patterns can support diagnosis, though they are not present in every case.

• Drug-Resistant EpilepsyRelated: EEG can help classify seizures and identify patterns that guide treatment.

• Multiple Sleep Latency TestRelated: EEG signals help technicians identify when sleep begins and classify its stages.

• Angelman syndromeRelated: Characteristic EEG patterns can support clinical assessment, though they do not establish the genetic cause.

• Absence seizureRelated: EEG can reveal seizure activity even when outward behavior shows only a brief pause.

• Neurological disorderRelated: It can identify abnormal brain activity relevant to seizures and other conditions.

• Febrile seizureRelated: It is generally not needed after a typical simple febrile seizure in a healthy child.

• Psychogenic non-epileptic seizureRelated: EEG helps assess whether a recorded episode has an epileptic electrical correlate.

• WaveformRelated: Brain rhythms are recorded as changing voltage waveforms.

• Behavioral neuroscienceRelated: Its timing precision helps relate rapid neural changes to behavior.

• WakefulnessRelated: EEG patterns help distinguish waking from sleep and altered states.

• Depolarization (neuroscience)Related: Its signals reflect coordinated electrical activity involving neuronal membrane currents.

• Dravet syndromeRelated: EEG findings can support evaluation, though early results may be normal or nonspecific.

• Lennox–Gastaut syndromeNarrower topic: EEG helps identify the characteristic patterns used to support diagnosis.

• Edgar AdrianRelated: Adrian helped bring attention to brain rhythms through early electroencephalographic research.

• NeurolinguisticsRelated: Its millisecond timing reveals when brain responses to linguistic events occur.

• Sturge–Weber syndromeRelated: EEG helps assess seizures and identify abnormal electrical activity.

• Transmissible spongiform encephalopathyRelated: Characteristic EEG patterns can support diagnosis in some forms of Creutzfeldt–Jakob disease.

• 1p36 deletion syndromeRelated: It helps evaluate seizures, which can occur in the syndrome.
