[The functional status of the brain in patients with abdominal aortic aneurysm]
Abstract:
We performed electroencephalography to 11 patients with abdominal aortic aneurysm in order to investigate the functional status of the brain. The relative potency (RP) of the main rhythms (alpha, beta, teta and delta) was increased, as well as the beta/alpha activation ratio. The increase of low-frequency rhythms (delta and teta) indicates the brain cortex hypoxia. The high-frequency reactivity of the brain (alpha- and beta-rhythms) was decreased in such patients, which was probably due to the decreased sensitivity of the receptor zone of the upper respiratory tract.
