Trial Outcomes & Findings for Combined Levothyroxine/Liothyronine Supplementation in Hypothyroid Patients With Brain Tumors (NCT NCT00488644)

NCT ID: NCT00488644

Last Updated: 2013-06-24

Results Overview

At baseline, each participant's scores for standardized/widely-used NCF exams are recorded (recalled words/objects/sequence repetition/etc per tests listed below). After 8 weeks liothyronine therapy, participants are tested again and scores compared to baseline scores. If the participant recalls more numbers/objects/sequence repetition faster/etc., than previous scores, this constitutes an improvement in NCF function for that individual. Scores are not compared to other participants. NCF tests: Memory by RAVLT (Rey Auditory Verbal Learning Test), scored by the number of words correctly recalled at different timepoints; Attention by Digit Span Exam (accurately repeating a sequence of numbers just spoken); Processing speed by Digit Symbol Exam (accurately matching numbers with associated symbols) Executive function by Trail Making Tests and Controlled Oral Word Association; Motor dexterity evaluated by correctly placing pegs in pegboards in a specified time.
