There were examined 92 persons (mean age - 22,3 years old). Among them there were 67 pts with AIT (basic group) and 25 healthy people. Intellectual level in AIT was examined in 4 groups. The 1<sup>st</sup> group of 25 pts is controlled; the 2<sup>nd</sup> - of 24 pts - with euthyreosic AIT; the 3<sup>rd</sup> of 22 pts - with subclinic hypothyreosis; the 4<sup>th</sup> of 21 pts - with manifestal hypothyreosis. There were used clinic, ultrasonic investigations, determing free thyroxin fraction, TTG. The evaluation of mental development with calculating intellectual index IQ was investigated by means testing of D. Veksler method, adapting by A. Yu. Panasyuk. Data received revealed, that average total, verbal and nonverbal parameters in control group were 114 ± 8,1; 103 ± 23,1; 113 ± 15,2 respectively. AIT development was accompanied by the decrease of intellectual level by data of the same tests. There were revealed lower levels of memory volume in AIT, than in control group.
