early stage
middle stage
late stage
end stage

Explanation:

• Question 6: Delirium is an acute, reversible, organic disorder with cognitive dysfunction symptoms. Pick's disease is a form of dementia (progressive, not acute - reversible). Parkinson's is a movement disorder (not primarily a cognitive - dysfunction - based acute - reversible organic disorder). Dementia is a chronic, progressive condition (not acute and reversible).
• Question 7: Brain tissue examination (such as in autopsy) is the definitive way to diagnose Alzheimer's as it can show the characteristic plaques and tangles. Mini - mental status exam, blood test, and psychological examination can help in the clinical diagnosis but are not definitive.
• Question 8: In the early stage of Alzheimer's, a person has memory problems but can still function independently. In the middle stage, more significant functional impairment occurs. In the late and end stages, the person is highly dependent.

Answer:

1. Delirium
2. Brain tissue examination
3. Early stage
