Abstract : Hypothyroidism affects cognition in a multitude of ways; however, verbal memory is a consistently affected domain. Verbal memory, which is a memory for verbally presented material, may be enhanced using semantic clustering. Imaging studies have shown that the hypothyroid brain has many functional and structural abnormalities in areas that are important for semantic clustering. The current study aimed at analyzing the semantic clustering among overt and subclinical hypothyroid subjects.46 hypothyroid subjects were contacted who were attending the outpatient ward of the Department of Endocrinology and Metabolism, Sir Sundarlal Hospital, Institute of Medical Sciences, Banaras Hindu University. 26 patients were overt hypothyroid, 20 were subclinical hypothyroid, and 20 healthy control patients were also recruited and were matched on age, education and gender. Both multivariate and univariate analyses of variance revealed a significant effect of hypothyroidism, and the hypothyroid group performed significantly inferior in comparison to the healthy controls on semantic clustering measures. It is clear from the current study's findings that hypothyroidism, whether overt or subclinical, can affect semantic clustering among young hypothyroid patients while learning new material.
