Alzheimer‌ ‌disease‌ ‌in‌ ‌humans‌ ‌is‌ ‌associated‌ ‌ with‌ ‌the‌ ‌deficiency‌ ‌of‌

Options

A. Acetylcholine‌
B. Gamma‌ ‌aminobutyric‌ ‌acid‌ ‌(GABA)‌ ‌
C. Dopamine‌
D. ‌Glutamic‌ ‌acid

Answer

**Step-by-Step Solution:**

1. **Understanding Alzheimer's Disease**: Begin by recognizing that Alzheimer's disease is a neurodegenerative disorder that primarily affects memory and cognitive functions.

2. **Identifying Neurotransmitters**: Understand that neurotransmitters are chemicals that transmit signals in the brain. They play a crucial role in communication between neurons.

3. **Recognizing the Role of Acetylcholine (ACH)**: Acetylcholine is a key neurotransmitter involved in memory and learning processes. It is essential for cognitive functions.

4. **Research Findings**: Studies have shown that individuals with Alzheimer's disease have a decreased concentration of acetylcholine. This reduction affects both the levels and the functionality of this neurotransmitter.

5. **Conclusion**: Since Alzheimer's disease is associated with a deficiency in acetylcholine, it can be concluded that the deficiency of acetylcholine is linked to the symptoms and progression of Alzheimer's disease.

6. **Final Answer**: The deficiency associated with Alzheimer's disease in humans is acetylcholine (ACH).
