Features of EEG Examinations in Patients with Anemia

Abstract: Anaemia is a common haematological disorder that may contribute to neurological symptoms due to impaired cerebral oxygenation. This study investigated the electroencephalographic (EEG) features in patients with different types and severities of anaemia. Fifty-two anaemic patients with neurological complaints underwent standard EEG examination. Abnormalities were observed in 65.4% of cases, most commonly diffuse background slowing and decreased alpha rhythm. The severity of EEG changes was significantly associated with lower haemoglobin levels and more pronounced in patients with megaloblastic anaemia. The results suggest that EEG can reveal functional cerebral disturbances in anaemic individuals, particularly those with moderate to severe anaemia. EEG may serve as a valuable, non-invasive tool for assessing subclinical brain dysfunction in patients with haematological conditions.
