Tobias has recently been diagnosed with schizophrenia. He frequently experiences visual hallucinations, reporting that he sees glowing geometric patterns floating in his field of vision. He also suffers from delusions of grandeur, firmly believing he has been chosen by a supreme being to decode secret messages in classical music. His speech is highly disorganized, often switching abruptly from one unrelated topic to another (derailment). Tobias’s mother was also diagnosed with schizophrenia in her twenties.
