Which of the following can be categorised as an age - related disorder ?

Options

A. Myasthenia gravis
B. Tetany
C. Muscular dystrophy
D. Osteoporosis

Answer

To determine which of the following options can be categorized as an age-related disorder, we will analyze each option one by one:

1. **Myasthenia Gravis**:
- This is a neuromuscular disorder characterized by weakness in the skeletal muscles. It is not specifically associated with aging, as it can occur in individuals of any age. Therefore, this option is incorrect.

2. **Tetany**:
- Tetany is a condition that involves increased neuromuscular excitability, often due to low calcium levels in the blood (hypocalcemia). It is not primarily associated with aging, making this option also incorrect.

3. **Muscular Dystrophy**:
- Muscular Dystrophy is a genetic disorder that results in progressive weakness and loss of muscle mass. While it affects muscle function, it is not classified as an age-related disorder, as it is inherited rather than acquired with age. Thus, this option is incorrect.

4. **Osteoporosis**:
- Osteoporosis is a condition characterized by weakened bones that become brittle and are more prone to fractures. It is commonly associated with aging, as bone density decreases over time, particularly in postmenopausal women. Therefore, this option is correct and is categorized as an age-related disorder.

**Final Answer**: The correct answer is **Osteoporosis** (Option 4).
