Answer: (D)

Verified step by step guidance

1. Step 1: Understand the term 'neurodegenerative disease' — these are disorders characterized by the progressive loss of structure or function of neurons, including diseases like Parkinson's disease and Alzheimer's disease.
2. Step 2: Recognize that abnormal sleep patterns, such as REM sleep behavior disorder, are commonly associated with certain neurodegenerative diseases, particularly Parkinson's disease.
3. Step 3: Review the options given: Generalized anxiety disorder, Asthma, Irritable bowel syndrome, and Parkinson's disease, and identify which are neurodegenerative diseases.
4. Step 4: Note that Generalized anxiety disorder, Asthma, and Irritable bowel syndrome are not neurodegenerative diseases, whereas Parkinson's disease is a well-known neurodegenerative disorder.
5. Step 5: Conclude that Parkinson's disease is the correct answer because it is a neurodegenerative disease linked with abnormal sleep patterns.
