Question

All of the following are anatomical changes that occur within the brains of Alzheimer's patients EXCEPT:

a)cell degeneration in the sensory-motor cortex.
b)the emergence of neuritic plaques in the cerebral cortex.
c)the cortex shrinks losing about one-third of its volume.
d)cell loss in the entorhinal cortex.

Answer 1

Alzheimer's disease is associated with various anatomical changes in the brain, including the development of amyloid plaques and neurofibrillary tangles, loss of synapses and neurons, shrinking of brain volume, and cell loss in the entorhinal cortex. However, cell degeneration in the sensory-motor cortex is not among the anatomical changes that occur in Alzheimer's disease.

Step-by-step explanation:

All of the following are anatomical changes that occur within the brains of Alzheimer's patients except for cell degeneration in the sensory-motor cortex.

Alzheimer's disease is characterized by the development of amyloid plaques between brain cells and neurofibrillary tangles inside of neurons. These abnormal changes in the brain are associated with the loss of synapses between neurons and the eventual death of neurons. The brain also experiences an overall shrinking of volume and cell loss in the entorhinal cortex. However, there is no specific mention of cell degeneration in the sensory-motor cortex as one of the anatomical changes that occur in Alzheimer's disease.
