Which of the following conditions is not linked to deficiency of thyroid hormone?

Options

A. Cretinism
B. Goitre
C. Myxoedema
D. Exophthalmia

Explanation

To determine which condition is not linked to a deficiency of thyroid hormone, we can analyze each option provided:

1. **Cretinism**: This condition is a result of severe deficiency of thyroid hormones during early development, leading to stunted growth and mental retardation. Therefore, it is linked to thyroid hormone deficiency.

2. **Goiter**: Goiter is an enlargement of the thyroid gland, which can occur due to insufficient thyroid hormone production. This is often due to a lack of iodine in the diet, leading to thyroid hormone deficiency. Thus, goiter is also linked to thyroid hormone deficiency.

3. **Myxedema**: This condition is associated with severe hypothyroidism in adults, characterized by swelling of the skin and underlying tissues. It is directly linked to a deficiency of thyroid hormones.
