Abstract

The Wada test or intracarotid amobarbital procedure is commonly used to determine hemisphere dominance for language and memory. This study presents the first standardised Wada protocol for Russian-speaking population. First, we provided the background on the Wada procedure and made the comparison of two most widely accepted standardised protocols, the Montreal and the Seattle ones. Next, the whole procedure of the Wada test according to our protocol was presented. Additionally, the main types of speech errors that may occur during the procedure were analysed. The protocol was first tested in 20 non-brain-damaged participants. Finally, the newly designed protocol was clinically piloted, with resulted in revealing its high reliability. With the new protocol, it was possible to determine for each of the tested patients, which hemisphere was responsible for language, and which - for memory.
