Explanation:

• Question 6: In the late - stage of Alzheimer's, patients may have difficulty swallowing, which can lead to aspiration pneumonia (inhaling food or liquid into the lungs). Hypertension, heart failure, and arthritis are not directly common late - stage complications specific to Alzheimer's in the context of the disease's progression.
• Question 7: Delirium is an acute (sudden - onset), reversible (can be treated and symptoms can go away), organic (related to physical causes) disorder with cognitive dysfunction. Pick's disease is a type of dementia (progressive), Parkinson's is a movement disorder with some cognitive symptoms but is not acute and reversible in the same sense as delirium, and dementia is a general term for a chronic (long - term) decline in cognitive function.
• Question 8: Paranoia is a belief that others are out to harm (e.g., poison) the person. An illusion is a misperception of a real stimulus, a catastrophic reaction is an over - reaction to a situation (usually in dementia patients), and a hallucination is a perception without a real external stimulus.
• Question 9: Vitamin B (especially B12) deficiency can cause dementia or dementia - like symptoms. Iron deficiency causes anemia, vitamin D deficiency is related to bone health and some immune functions, and calcium deficiency is related to bone and muscle function.
• Question 10: Currently, the definitive diagnosis of Alzheimer's is made through brain tissue examination (usually post - mortem) to look for characteristic plaques and tangles. The mini - mental status exam is a screening tool, blood tests can rule out some other conditions but not definitively diagnose Alzheimer's, and a psychological examination can assess cognitive function but not give a definitive diagnosis of Alzheimer's.

Answer:
