Abstract
Article focuses on the use of 99mTc-HMPAO brain SPECT for evaluation of cerebral blood flow in patients with arterial hypertension and identification of the relationship of brain perfusion and cognitive function. Using SPECT of brain with 99mTc-HMPAO it was found out that hypertensive patients even in the absence of focal neurological symptoms have hypoperfusion of the brain which leads to cognitive dysfunction: decreased attention, psychomotor speed and slow thought processes.
