The correct answer is that Gregory Baker is diagnosed with the mental disorder known as Schizophrenia.

Schizophrenia is described as a persistent and excessive intellectual disorder that affects how a person thinks, feels, and behaves. humans with schizophrenia might also appear like they've misplaced contact with truth. even though schizophrenia is not as common as different mental disorders, the signs and symptoms may be very disabling.
