Note the following
A) SCID B) Grave's disease C) Rheumatoid arthritis D) Alzheimer's disease E) Myasthenia gravis F) Addison's disease G) Parkinson's disease
Which of the above are auto immune disorders

Options

A. B, C, E&F
B. A, D, F & G
C. B, E, F & G
D. A, B, C & D

Answer

To determine which of the listed conditions are autoimmune disorders, we will analyze each condition one by one.

### Step-by-Step Solution:

1. **Identify the conditions**: The conditions listed are:
- A) SCID (Severe Combined Immunodeficiency)
- B) Grave's disease
- C) Rheumatoid arthritis
- D) Alzheimer's disease
- E) Myasthenia gravis
- F) Addison's disease
- G) Parkinson's disease

2. **Define Autoimmune Disorders**: Autoimmune disorders occur when the immune system mistakenly attacks the body's own cells, tissues, or organs.

3. **Analyze each condition**:
- **A) SCID**: This is not an autoimmune disorder; it is an immunodeficiency disorder caused by genetic defects affecting the immune system.
- **B) Grave's disease**: This is an autoimmune disorder where the immune system attacks the thyroid gland, leading to overproduction of thyroid hormones.
- **C) Rheumatoid arthritis**: This is an autoimmune disorder characterized by chronic inflammation of the joints due to the immune system attacking the synovium.
- **D) Alzheimer's disease**: This is not an autoimmune disorder; it is a neurodegenerative disease characterized by the buildup of proteins in the brain.
- **E) Myasthenia gravis**: This is an autoimmune disorder where antibodies block or destroy the communication between nerves and muscles, leading to weakness.
- **F) Addison's disease**: This is an autoimmune disorder where the immune system attacks the adrenal glands, leading to insufficient production of hormones.
- **G) Parkinson's disease**: This is not an autoimmune disorder; it is a neurodegenerative disorder caused by the loss of dopamine-producing neurons in the brain.

4. **List the autoimmune disorders**: Based on the analysis:
- Grave's disease (B)
- Rheumatoid arthritis (C)
- Myasthenia gravis (E)
- Addison's disease (F)

### Final Answer:
The autoimmune disorders from the list are:
- B) Grave's disease
- C) Rheumatoid arthritis
- E) Myasthenia gravis
- F) Addison's disease
