(a) Mental retardation (b) Abnormal skin (c) Deaf-mutism (d) Stunted growth Which disorder is correctly described by these symptoms?

Options

A. Acromegaly
B. Myxedema
C. Exophthalmic goitre
D. Cretinism

Answer

To solve the question regarding the symptoms of a disorder, we will analyze each symptom and determine which disorder corresponds to them.

### Step-by-Step Solution:

1. **Identify the Symptoms**: The symptoms provided are:
- Mental retardation
- Abnormal skin
- Deaf-mutism
- Stunted growth

2. **Understanding Each Symptom**:
- **Mental Retardation**: This indicates a cognitive impairment or developmental delay.
- **Abnormal Skin**: This can refer to various skin conditions, often associated with hormonal imbalances.
- **Deaf-Mutism**: This refers to the inability to hear and speak, which can be a result of genetic or developmental issues.
- **Stunted Growth**: This suggests that the individual has not reached their expected height or physical development.

3. **Evaluate Possible Disorders**:
- **Acromegaly**: This is characterized by excess growth hormone in adults, leading to disproportionate growth. It does not cause mental retardation or the other symptoms listed.
- **Myxedema**: This is related to low thyroid hormone levels in adults, leading to edema and skin issues, but does not typically cause mental retardation or deaf-mutism.
- **Exophthalmic Goiter**: This condition involves excessive thyroid hormones and does not align with the symptoms, as it typically does not cause mental retardation or stunted growth.
- **Cretinism**: This is a condition that arises from a deficiency of thyroid hormones during pregnancy or early childhood. It is associated with mental retardation, stunted growth, abnormal skin (often dry), and can include deaf-mutism.

4. **Conclusion**: Based on the analysis, the disorder that correctly describes the symptoms of mental retardation, abnormal skin, deaf-mutism, and stunted growth is **Cretinism**.

### Final Answer:
The disorder described by the symptoms is **Cretinism**.
