ABSTRACT:   Although both subclinical hyper- and hypo-thyroidism have been implicated as risk factors for cognitive decline, the clinical relevance of this finding is still controversial. This cross-sectional analytical study aimed to find out the association between subclinical thyroid dysfunction and cognitive function of elderly people. A total of 157 elderly (60-70 years old, 47 men and 110 women) from Thabawa Meditation Center, Thanlyin participated in the study. Serum triiodthyronine (T3), thyroxine (T4) and thyroid stimulating hormone (TSH) were measured as indicators for thyroid function and determined by direct sandwich ELISA method. Cognitive function was assessed by using mini-mental state examination (MMSE). It was found that 85.99% of the elderly had normal thyroid function and 14.01% had thyroid dysfunction. The most common was subclinical hypothyroidism (11.46%), followed by subclinical hyperthyroidism (1.27%) and overt hyperthyroidism (1.27%), respectively. Among the elderly, 49.04% had normal cognitive function (MMSE score ≥28), 38.85% had impaired cognitive ability (MMSE score between 27-24) and 12.11% had dementia (MMSE score ≤23). Although no significant correlation was found between T3, T4, TSH level and MMSE score in the whole study group, a moderate degree of significant negative correlation between TSH level and MMSE score (r=-0.49, p<0.05, n=18) was found in those with subclinical ypothyroidism. This could be simply due to the fact that TSH is the most sensitive measure of thyroid status. This study pointed out that subclinical hypothyroidism is the most prevalent thyroid dysfunction among the asymptomatic elderly and those with subclinical hypothyroidism were not more likely to have cognitive impairment.
