Cаse: A 28-yeаr-оld mаn presents fоr a checkup. Medical recоrds indicate a 3-year history of hospitalizations for mania and depression. The last admission occurred 7 months ago and was due to a suicide attempt after a major depression. The patient has been taking lithium since the last hospitalization; there have been no further mood disturbances, but his mother relates that the patient remains convinced that the "city officers" poisoned the water system over the last 2 months. He refuses to drink tap water. His mother heard him talking alone in his room, and she found several bottles of water under his bed. She reports he has not been very social with his friends over the last 6 months and is showing signs of depression. On examination, the patient appears disheveled; he experiences auditory hallucinations and persecutory delusions throughout the interview. His speech is disorganized. Question: What is the most likely diagnosis?
