Describe the neuroanatomical changes that accompany Down syndrome and Alzheimer's disease. In what way are these diseases similar to each other? How do they differ from one another?
What will be an ideal response?
Answer: Down syndrome is a congenital disorder involving profound mental retardation. The disorder is induced by the presence of an additional 21st chromosome. After age 30, a Down's person will experience brain atrophy and degeneration (a similarity to that of Alzheimer's disease). Alzheimer's disease (AD) involves dementia, which first appears as a memory difficulty. AD is associated with severe degeneration of brain structures such as the hippocampus and neurocortex. Both disorders are characterized by abnormal intracellular abnormalities.
