Primary Outcome Measures:
- Number of Participants Demonstrating Improvement With Impaired NCF (Neuro-cognitive Function) Based on Results of a Series Neuro-cognitive Exams Administered at Baseline and Again 8 Weeks After Liothyronine Therapy [ Time Frame: At baseline and after 8 weeks of treatment ] [ Designated as safety issue: No ]NCF exams administered before and after 8 weeks liothyronine therapy to measure: 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.
