Abstract

Transkranijska Doppler ultrasonografija (TCD) je neinvazivna dijagnostička metoda kojom možemo pratiti promjene brzina strujanja krvi (BSK) u cerebralnim arterijama te na taj način procijeniti lokalnu metaboličku aktivnost moždanog tkiva. Dosadašnja istraživanja utvrdila su korelaciju mentalne aktivnosti prilikom rješavanja određenih kognitivnih zadataka s povećanjem protoka krvi kroz srednje cerebralne arterije (MCA). Naše istraživanje uspoređivalo je BSK u MCA između zdravih mladih muškaraca i žena tijekom izvođenja dva kognitivna zadataka (testa verbalne fluentnosti (VFT) te Stroop testa s nekongruentnim podražajem). U ispitivanje je uključeno 18 dobrovoljaca (7 muškaraca i 11 žena). BSK mjerene su istovremeno u obje MCA kroz transtemporalni koštani prozor. Nađeno je statistički značajno povećanje BSK kod muškaraca i žena prilikom izvođenja oba kognitivna zadatka. Prilikom izvođenja oba zadatka nije pronađena statistički značajna razlika u BSK u MCA između spolova, niti je pronađena statistički značajna razlika u BSK između lijeve i desne MCA u pojedinog spola.

Abstract (english)

Transcranial Doppler ultrasonography (TCD) is a noninvasive diagnostic method that enables monitoring of blood flow velocity (BFV) changes in the cerebral arteries and thereby to assess local metabolic activity of brain tissue. Previous studies have established a correlation between mental activity during cognitive tasks performance and increasing BFV through the middle cerebral arteries (MCA). The aim of our study was to compare BFVs in the MCA between healthy young men and women during the performance of two cognitive tasks (verbal fluency test (VFT) and the Stroop test with incongruent stimuli). The study included 18 volunteers (7 men and 11 women). BFVs were measured simultaneously in both MCA through transtemporal bone window. A statistically significant increase in BFV was found in men and women during the performance of both cognitive tasks. No statistically significant gender differences in BFVs were found during cognitive tasks performance. Additionally, no statistically significant difference in BFV between the left and right MCA was found in females or males.
