Research has been made on the clinical significance of pleomorphic delta-wave activity (PDA). The purpose of this article is to further investigate the clinical significance of persistent PD and its relationship with CT. A group of 117 patients with persistent, localized PDA wave EEG included 100 of them and had a CT scan. Age from March to age 87 (average 41 years). 55 males and 45 females. The most common diseases are stroke and epilepsy. 32 cases of ischemic stroke, hemorrhagic stroke in 6 cases, epilepsy 21; tumor 13; 11 cases of head trauma without hematoma, 9 cases of head trauma with hematoma; 1 case of arteriovenous malformations; 1 case of acute infant hemiplegia, 1 case of viral encephalitis, 1 case of epidural water cyst, 1 case of metabolic encephalopathy, 1 case of eclampsia and 1 case of unknown neurological disease. 68% of them
