Answer 1

d. Unusual for mild neurocognitive disorder to involve speech aphasia

Step-by-step explanation:

Most persons as they age because of changes in brain chemistry and physiology become slower in thinking and controlling attention. The biological explanation for this is because the fatty insulation layer surrounding the nerves become worn out. The electrical impulses going to and from the brain is not sufficiently conducted and some of the messages is lost or delayed.

This is a normal part of aging, dementia however, is not. This could involve a sudden onset of memory loss that progressively worsens over time along with increasing speech aphasia. This worsens over time and the person eventually losses all cognition.
