Different types of normal brain waves. An EEG records patterns of brain activity. Among the basic waveforms are the alpha, beta, theta, and delta rhythms. Alpha waves occur at a frequency of 8 to 12 cycles per second in a regular rhythm.They are present only when you are awake but have your eyes closed.he 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. Patients with lesions of the brain, which can result from tumors or stroke, may have unusually slow EEG waves, depending on the size and the location of the lesion.
Results of Electroencephalography. 1  A neurologist will evaluate your brain wave patterns for evidence of any abnormality. For example, seizure activity is indicated by rapid, spiking waves, while cerebral lesions such as tumors or blood clots will result in abnormally slow EEG waves. The presence of an inflammatory brain disease, such as meningitis or encephalitis, may cause diffuse and slow brain waves.
