Definition of electroencephalogram in English:



  • A test or record of brain activity produced by electroencephalography.

    ‘I had an electroencephalogram and a number of other tests’
    • ‘When possible, an electroencephalogram should be obtained to assess prognosis and select appropriate drug therapy.’
    • ‘The electroencephalogram shows no sign of electrical activity in the brain, as recorded from a minimum of eight points.’
    • ‘Computed tomography scans showed that her cerebral hemispheres had atrophied, and electroencephalograms showed that she was without any cortical activity.’
    • ‘Her brain activity was monitored with the help of an electroencephalogram or EEG.’
    • ‘Sequential electroencephalograms showed abnormal background activity with evidence of seizures, although these were not apparent clinically.’
    • ‘Computed tomography of the brain and an electroencephalogram gave normal results; treatment with carbamazepine was ineffective.’
    • ‘Encephalopathy usually can be documented by slow wave activity on an electroencephalogram.’
    • ‘The electroencephalogram and computed tomographic scan were within normal limits.’
    • ‘Nearly all of the studies we reviewed mentioned the standard electroencephalogram as an absolute requirement for the diagnosis of epilepsy.’
    • ‘It is necessary to investigate the relationship between each muscle stiffness and brain activities by electroencephalogram, positron emission tomography, and so on.’
    • ‘But internally, activity in your brain increases dramatically - recorded by an electroencephalogram in much the same way as an ECG measures your heart activity.’
    • ‘An extensive evaluation including ECG, echocardiogram, Holter studies, chest radiograph, brain MRI, electroencephalogram, and carotid ultrasound was unrevealing.’
