Answer to Question 1

D
Sleep deprivation may sometimes trigger mania. In some persons, symptoms seem to respond to restorative sleep.

Answer to Question 2

A
A diagnosis of Alzheimer's is made by ruling out all other possible reversible or irreversible causes of mental dysfunction. Alzheimer's, like other forms of dementia, is a diagnosis of exclusion. However, in the absence of other treatable conditions that may cause the symptoms, an early diagnosis of Alzheimer's is also important in that it will allow affected individuals to receive treatment earlier and derive greater benefit from them.
