Question

Quizplus · Accepted Answer

Lavinia is exhibiting symptoms of delirium, which includes confusion, hallucinations, and changes in sleep patterns. Dementia is a long-term decline in cognitive functioning, which is not necessarily sudden. Focal brain damage would cause more specific symptoms related to the area of the brain affected. Depression may cause changes in sleep patterns and mood, but is not likely to cause hallucinations and confusion.
