Which of the following diseases would you expect might result from a dysfunction of the basal nuclei?

• A. Multiple sclerosis (MS).
• B. Guillain-Barré Syndrome.

Answer: (C)

Verified step by step guidance

1. Begin by understanding the role of the basal nuclei in the brain. The basal nuclei, also known as basal ganglia, are a group of structures linked to the control of voluntary motor movements, procedural learning, and cognition.
2. Consider the symptoms and characteristics of each disease listed. Parkinson's Disease is characterized by tremors, stiffness, and difficulty with balance and coordination, which are directly related to motor control issues.
3. Multiple sclerosis (MS) is primarily an autoimmune disorder affecting the central nervous system, leading to demyelination. It does not primarily involve the basal nuclei.
4. Guillain-Barré Syndrome is an acute polyneuropathy affecting the peripheral nervous system, often triggered by an infection. It does not involve the basal nuclei.
5. Alzheimer's Disease primarily affects memory and cognitive function due to the degeneration of neurons in the brain, particularly in the hippocampus and cortex, rather than the basal nuclei.
