Explanation:

For question 9: In Alzheimer's dementia, aggressiveness and hallucinations are more common in the middle stage. In the early stage, memory loss (especially short - term) is more prominent. In the late and end stages, there is more severe cognitive decline and physical deterioration rather than the onset of these specific behavioral symptoms (aggressiveness and hallucinations) as a main feature.
For question 10: Vitamin B (especially B12 and folate) deficiency can be associated with dementia or dementia - like symptoms. Iron deficiency is mainly related to anemia. Vitamin D deficiency has links to other health issues (e.g., bone health, immune function). Calcium deficiency is mainly related to bone and muscle function.

Answer:

1. Middle stage
